The Dairy Edge

John McCabe, Seamus Kearney and Sean Callan, Advisors on the Teagasc Aurivo, Teagasc Tirlán and Teagasc Lakeland joint programmes, join Stuart Childs to give a more countrywide feel for the situation on farms around Ireland currently following the recovery in grass growth in the last few weeks.The impact of the drought varied significantly by region with the west generally less affected, while parts of the Lakelands, due to the geography of the catchment, and especially the south and east experienced major reductions in grass growth and farm cover which in turn led to substantial supplementary feeding.Seamus explains that the winter fodder shortages are the main concern and that although grass growth and farm covers have recovered, many farms in the Tirlán catchment have used large quantities of silage and meal during the summer. Fodder budgets have identified shortages of approximately two bales per cow on the lighthouse farms, making early feed purchasing and planning essential. Meanwhile, some of farms on the Lakeland programme have significant surplus but with wet starts and ends to the year more common, it may well be needed in the future.The key message is to quantify and act early.  Farmers should complete fodder budgets, manage the final grazing rotation carefully, assess grazing infrastructure and improve if possible or plan to improve in the future to maximise opportunities to get cows to grass even in challenging conditions. Where deficits have been identified, consider options such as buying fodder, using meal to stretch existing supplies, and/or removing underperforming/empty cows earlier to protect winter feed stocks.For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Teagasc ruminant nutritionist, Aisling Claffey, joins James Dunne to discuss managing dairy cow nutrition as we move out of the drought conditions. With many cows having been fed increased levels of silage and concentrate, the return to grass needs to be managed carefully. We’ll discuss how farmers can make decisions around reducing silage and concentrate, what to monitor in cow performance, and also what to look out for with young stock grazing outside blocks.For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Dr. David Wall, Enterprise Leader of the farms and estate at Teagasc’s Environment Research Centre in Johnstown Castle, joins Stuart Childs to discuss the timing of fertiliser applications over the coming weeks to maximise the return from nutrients applied while minimising the risk to water quality.This is particularly important in drought-affected areas, where low grass growth and reduced nutrient uptake have increased the risk of nutrient losses.David first addresses the concept of calendar farming, explaining that fertiliser deadlines are driven by declining nutrient uptake rather than soil trafficability. As daylight levels fall, grass growth and nutrient demand naturally decrease. Applying additional nitrogen above crop requirements will not generate extra growth and, particularly from mid-October onwards, will instead increase the risk of nutrient losses.Following the recent drought, David says farmers should make the most of natural soil mineralisation over the coming weeks. With moisture returning while soils remain warm, mineralisation can supply approximately 1 kg N/ha per day, potentially supporting around 35 kg DM/ha per day of grass growth.Lime also has an important role to play. Correcting soil acidity can improve nutrient availability and help release significant quantities of soil nitrogen over time, which can then support further grass growth.Despite the temptation to apply heavily now that the drought has broken, David advises farmers to use fertiliser and slurry sparingly and avoid over-application. In drought-affected areas where growth has resumed, applications of around 20–25 kg N/ha from fertiliser or slurry can provide additional growth on top of what soil mineralisation is already supplying.Slurry should also be prioritised where appropriate, particularly where tanks need to be emptied before October. David recommends applying slurry regularly over the coming month ahead of the closing period commencing on October 1st.This approach will help maximise the return from the nutrients applied, reduce the risk of losses to water and also help spread contractor workloads over the coming weeks.For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Raymond Ryan, Milk Quality Advisor for the Limerick and Clare regions with Dairygold, joins Stuart Childs to discuss staying on top of milk quality.Raymond explains that milk quality in 2026 is generally holding up, with cell count and TBC broadly similar to previous years, but drought and difficult weather have created localised problems.Dirty conditions are the main risk, particularly for thermoduric bacteria and farmers should keep cows and parlours clean, manage sacrifice paddocks or cubicles carefully, ideally dry-wiping cows before milking. Making sure machine maintenance such as liners and rubberware has been done is also an important management step.Raymond says that, where problems arise, early action and implementation of consistent routines are critical: monitor cell counts/TBC and act quickly on rises, ensure adequate water and nutrition, remove persistent high-cell-count cows where appropriate, and maintain proper plant washing with sufficient hot water, chemicals, temperature and turbulence. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Eoghan Byrne, project manager in FRS farm services, and MTU Agriculture student, Cormac Harnett, who works as an operator with the FRS in Cork joins Stuart Childs to discuss how farmers can help themselves get a bit of a break from the work by making it easier to work on their farm.Both Eoghan and Cormac say that planning and communication are central by giving operators advance notice and clearly stating what needs to be done, how to do it on your farm and when it needs to be done. Farmers leaving checklists, notes on how to do different tasks where relevant and pre-visits from the operator can help avoid confusion or mistakes being made.Cormac points out that having the farm equipment and materials ready means operators can get straight to the job, making the arrangement more efficient for both farmer and operator, saving time and money and making life a little easier for everyone as stress can be avoided by being prepared.Eoghan finishes up the conversation by highlighting that many young operators want to progress in agriculture. Farm-relief work can provide experience and a potential pathway into farm management or collaborative farming, but both Eoghan and Cormac are clear that creating a positive, respectful workplace is important for attracting and retaining the next generation.  For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Colman Purcell, Nutritionist with Dairygold Agri Business, joins Stuart Childs to discuss managing stock in drought or near drought conditions.Colman praises the farmers in the Dairygold catchment who have been affected by the dry weather for how they have dealt with it up to now, maintaining milk and protein performance, a response that he credits to their knowledge of how to react in these situations due to their experience of them in the last decade. Colman says that it is important to maintain cow performance by avoiding feed shortages with the priority being to maintain dry matter intake and milk production by supplementing early. Monitor milk yield and milk proteins and react quickly if performance drops as these are good indicators of nutritional status.Filling the gap created by the lack of grass will depend on how severe the grass deficit is and what the help and facilities on the farm are like. In some cases, feeding will be pushed as high as 9kg in the parlour feed due to an inability to feed outside of the parlour. People will need to see what will work best for their farm. Concentrate protein should be ok at 16% but an 18% protein ration may be appropriate, particularly where cows are receiving significant forage. Again, monitoring the performance of the herd will help decisions here.Young stock while appearing content in the current conditions will still need to be fed in order to keep them growing, so supplementation will be necessary where there is grass shortage for these animals. Forward beef cattle that are based on weight are forward enough to start on finishing diet and should be started on this to reduce stocking rates and avoid these animals slipping back which would delay their finishing later in the year.Furthermore with demand increasing, delivery logistics may become more challenging. Farmers should calculate feed requirements and order well in advance to avoid running out.For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

John O’Loughlin, Head of Sustainability at Grassland Agro, joins Stuart Childs to discuss the impact of CBAM, fertiliser advice in dry conditions and two upcoming farm walks that will be worth attending this July. John first explains the EU's Carbon Border Adjustment Mechanism (CBAM) which is adding approximately €50/t to urea in 2026, with the potential to rise significantly in future years. While there has been discussion about suspending the charge during periods of high fertiliser prices, he believes this now looks unlikely, meaning farmers should expect CBAM to remain a factor in fertiliser costs. John recommends that farmers measure grass regularly and make decisions based on their own farm’s situation, as drought conditions are varying widely across the country from his perspective and one size won’t fit all in terms of advice.  Where soil moisture deficits become severe, nitrogen applications should be reduced or paused, but where growth remains good, protected urea is still a good choice as it will absorb water from the atmosphere. John stresses that potassium (K) and lime are essential for helping grass cope with drought and recover quickly afterwards. John describes K as the "engine oil" of the plant because of the role it plays in the movement of water and nutrients, and he says that correcting K and lime deficiencies are among the biggest, most cost-effective improvements farmers can make to maximise grass growth and resilience. Finally, John says listeners should consider attending two good days later this month in the Clonmel area with the Irish Grassland Dairy Summer Tour taking place on the farms of Michael and Ollie O’Gorman on the 21st and then the Tipperary Dairy Calf to Beef Open Day the following day at the Ballyvadin Farm near Fethard. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

With increasing pressure on dairy farms to reduce nitrogen inputs whilst maintaining profitability, technologies such as white clover are attracting renewed interest.  But how well does clover perform on heavier type soils that are common across the Border, Midlands and Western region, and how can farmers reduce fertiliser and feed nitrogen inputs without compromising grass growth or milk production? To help answer those questions, James Dunne is joined by Helena Walsh, PhD student with Teagasc, who has been leading a farm systems study at Ballyhaise Agricultural College examining the role of white clover in low nitrogen input grazing systems.  Helena discusses the establishment and performance of clover swards, the impact on pasture and animal production, nitrogen use efficiency, and the practical lessons farmers can take from this work. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

For this week’s Grass10 grazing management update, John Maher says concentrate input should be reduced on farms where grass supply is adequate (cover/LU >160 kg DM/LU).  A third of farms are over target and have a cover/LU >190 kg DM/ha. This will negatively impact:-       Grass quality - negative impact on animal performance-       Clean out of swards - feed wastage-       Grass recovery and subsequent quality June is challenging for grass quality as we are now in the main heading phase for perennial ryegrass.  Grass quality is critical for animal performance, particularly as young stock grass intake increases.  Walk the farm every 4-5 days to inform decision making. Plus the featured farmer is William Blackburn from Kilworth,Co.

Ricki Fitzgerald, Farm Manager of the Teagasc Moorepark Kilworth Farm, and Brian McCarthy, Researcher in Teagasc Moorepark, join Stuart Childs with a run down on how the year has gone so far on the Kilworth Farm and to talk a little about the Next Gen 2 trial that is in its first full year in 2026. Ricki says they had quite a good spring in 2026 despite the weather challenges with minimal health issues. Regular body condition scoring and managing cow condition was a significant part of this success.  Grazing, while challenging, happened almost every day during the spring but only because they had the cover to start with and excellent infrastructure on the farm. A batt latch bought a few years ago has been instrumental in facilitating grazing in the evening during the spring also.  The farm started breeding on April 27th and so far results have been exceptionally positive, with 96% of cows submitted in the first three weeks and early pregnancy scanning showing very high conception rates. Brian then spoke about the previous next generation trial and the outcomes of it and the the rationale for the current trial Next Gen 2 which is comparing National Average Holstein-Friesians with Elite Holstein-Friesians and Elite Jersey-cross cows.  The previous iteration of the trial  (2013–2016) showed that high-EBI cows were more fertile, survived longer in the herd, produced higher-value milk solids, and generated approximately €275 more profit per cow annually thus validating the EBI.  Early results from the set-up year of 2025 and the figures from 2026 so far indicate that elite genetics continue to deliver higher fat and protein percentages, increasing milk value compared with national-average cows.  However, this trial goes further than the effect of the genotypes as it is also looking at sustainability and beef performance through evaluating different stocking-rate systems, nitrogen-use efficiency, methane emissions, and overall environmental performance as well as examining how dairy cow genetics and beef sire selection affect dairy-beef calf value and lifetime beef performance. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

For this week’s Grass10 grazing management update, John Maher explains that June is a challenging month for grass quality as we are now in the main heading phase for perennial ryegrass. Pre grazing yield is too high on many farms:-       Watch rotation length (Target 18-21 days)-       Minimise stem content-       Grazing covers >1500 kg DM/ha will have a negative effect on animal performance, pasture cleanout, grass recovery and quality in the subsequent rotation Read more from this week’s Grass10 newsletter and subscribe for weekly updates at:https://bit.ly/Grass10-9thJune  For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

With breeding season reaching the midpoint on many spring-calving dairy farms, we're taking stock of how the season has progressed so far and discussing the key management decisions for the weeks ahead. Doreen Corridan, CEO of NCBC, joins James Dunne to discuss breeding performance to date, trends in dairy and beef semen usage, managing cows that have yet to be served, and the key actions farmers should focus on for the remainder of the breeding season. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

With the increased cost of fuel and fertiliser, Peter Doyle, Grassland Researcher in Teagasc, Grange, joins Stuart Childs to discuss the cost of growing grass, silage and other feeds. Peter outlines the costs that he uses in the Grange Feed Costing Model which are of course assumptions but are necessary for the model to function. He emphasises that grazed grass delivers the lowest feed cost, even with higher fertilser prices. The cost model estimates grazed grass at about 14c/kg dry matter (including land charge), compared with roughly 42c/kg dry matter for concentrates. Feed quality is important in the model as the energy of the feed influences the performance it delivers. Peter argues that delaying first-cut silage to chase higher yields given increased fuel costs to get better bang for the buck from contractor costs is a false economy.  Earlier cutting (around late May) produces higher-quality silage, improves the total energy yield of the overall two-cut system as well as supporting better animal performance, reducing the requirement for expensive concentrate supplementation. Big first cuts of low quality material don’t deliver more silage and are ‘penny wise, pound poor’ due to the cost they create subsequently. Peter also stresses that feed quality should be matched to the type of stock being fed. High-quality silage is needed for lactating cows and young stock, while lower-quality, higher-volume silage may suit dry cows.  He notes that alternatives such as maize and fodder beet can be useful but involve similar or higher costs, additional management requirements, and often require supplementary protein and minerals. Finally, Peter says that the cost of grazed grass doesn’t increase as significantly as the other feeds and thus people need to focus on grazed grass as their primary feed source and maximise the amount of it that they produce and consume to minimise their overall feed costs. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Claire Mooney, Catchment Coordinator for the Suir, joins Stuart Childs to discuss practical tips for farmers in relation to improving water quality. Claire first explains immediate on-farm actions to improve environmental compliance and efficiency, including better silage management, protecting waterways with fencing and alternative drinking points, improving slurry and effluent handling, using sulphur correctly, and how clover can reduce chemical nitrogen use. Claire discusses the need for farmers to prepare for tighter slurry storage rules in 2028 by assessing storage capacity now, working with advisors, exploring TAMS grants and capital allowances, and planning investments early rather than waiting until compliance becomes urgent. Finally, Claire stresses that small operational improvements can make a significant difference, such as separating soiled water from slurry, reducing rainwater entering tanks, fixing leaks, cleaning yards efficiently, and redesigning cow traffic areas to reduce unnecessary slurry storage demand and avoid a need to reduce stock numbers on foot of the new regulations that may be avoidable.  She also emphasises the importance of using slurry well and distributing it across the whole farm to reduce losses. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

For this week’s Grass10 grazing management update, John Maher says that the majority of farms are grazing covers too high. As we move further into May, grass composition is changing and keeping grass quality correct becomes more challenging. To ensure grass quality is maintained to maximise animal performance pre-grazing yield has to be between 1300-1400 kg DM/ha. Meanwhile, the featured farmer is Killian Brennan, from Kilcogy, Co.

For this week’s Grass10 grazing management update, John Maher says that we're now entering into higher growth rates and reproductive stage of the perennial ryegrass plant:·      Pre grazing yield must target 1300 - 1400 kg DM/ha on all farms·      This will enable the animals to graze and clean out the sward to 4 cm·      Grass should be green leaf from top to bottom For fertiliser, when spreading on dry stock farms it is important to include P (if allowance available), K and S, especially on paddocks that may have been damaged on the first rotation. Meanwhile, the featured farmer is Danny Bermingham, from Doonbeg, Co. Clare. Read more from this week’s Grass10 newsletter and subscribe for weekly updates at:https://bit.ly/Grass10-28thApril  For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Tom O’Connell, dairy farmer in Inniscarra, near Cork city, and John Maher of Grass10, join Stuart Childs to discuss the importance and management of reseeding. John first outlines the national figures which are poor in terms of the amount of reseeding taking place each year and this is a negative for the industry. Tom is the opposite, reseeding every year on both grazing platform and silage ground. Reseeding every year  is what Tom says allow him to have the confidence to take out the ground safe knowing he has responsive swards that will grow at sufficient levels to meet herd requirements while he waits for the reseed to slot back in, as evidenced by the performance of the spring 2024 and 2025 reseeds. Tom splits the 10% so that it isn’t all gone out together and generally takes the 2nd piece out when he knows the first bit is nearly ready to come back in. This as an insurance policy against having too high a stocking rate with all ground out at the same time.  Tom has also reduced his overall milking platform stocking rate through land acquisition and a slight reduction in cow numbers so that now his stocking rate with reseeded ground out is where his stocking rate was before he took out ground for reseeding in the past.  This is making the whole thing easier to tackle as at the higher stocking rate, he could be tight for grass at times and this was adding cost as well as compromising production. For Tom, reseeding is an essential element of each year’s work.John finishes up by highlighting that people often do a lot of the things right but fail to get the post emergence spraying and early grazing of the sward right. Tom is doing this very well as evidenced by his lack of need to spray for weeds between reseeding events in his paddocks. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com 

For this week’s Grass10 grazing management update, John Maher says that 42% of farms are well above target AFC (> 750 kg DM/ha) largely due to challenging grazing conditions. While each farm is individual, these key rules need to be applied:-       Maximum SR of 4.2 LU/ha-       Minimum AFC of 160 kg DM/LU Now is also a good time to assess clover content in your paddocks and the aim is to identify paddocks with a good clover content. The target is 20-25% clover content in April to allow for reductions in chemical N in May/June Meanwhile, the featured farmer is Tom McEvoy from Ballyragget,Co.

Teagasc Grassland Science Researcher, Mike Egan, joins James Dunne to discuss some of the common questions regarding establishing and managing grass clover swards.  Mike outlines the benefits for farmers but also discusses the challenges and learnings that have been seen throughout the Clover 150 commercial farm trial.   The correct chemical nitrogen strategy is outlined and why clover content should be the key deciding factor rather than fertiliser price when it comes to reducing nitrogen inputs.  Mike also outlines what farmers should be doing now with regards to assessing their own farm clover content and he also identifies opportunities to establish clover on farms over the coming weeks.   For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

For this week’s Grass10 grazing management update, John Maher explains how walking the farm will allow you to assess what your grass supply is (AFC). If you are below target AFC <650kg DM/ha:-       Reduce demand on the farm to lift AFC to 650kg DM/ha. This may require grazing additional land (silage ground, replacement heifer area)-       Increase feed supplementation (ration, silage)-       Remove surplus animals-       Hold rotation length using these options to ensure growth isn’t further hampered Walk the farm more frequently as grass growth and grazing conditions can and will change fast. There is also huge variation in fertiliser and slurry applied to date across the country owing to ground conditions and grass covers.  A focus should be put on getting nutrients where possible to ensure production is on track for the year ahead Meanwhile, the featured farmer is Declan Flynn from Kilmallock, Co. Limerick. Read more from this week’s Grass10 newsletter and subscribe for weekly updates at:https://bit.ly/Grass10-14thApril For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Mark Treacy, Dairy Specialist in Teagasc Clonakilty, joins Stuart Childs on this week’s Dairy Edge to discuss management tips for April. Mark explains that dairy farms are in various positions: some have moved too quickly into second-round grazing, others are well-balanced with remaining first-round grass, and some (especially on heavy ground) are delayed due to poor weather conditions. He then outlines the solutions such as housing some or all of the herd in order to get grass cover back up to where they need to be which might only take a week, or where there is a lot of grass on farm, tackling it from a number of angles including grazing, silage immediately once opportunity arises or longer term silage in some cases. Mark also spoke about the need for silage ground to be fertilised but to have cutting date influence the amount applied. With slurry application to most of this ground not an option, the advice is to cut early and return the slurry then. This will result in the same total yield with better quality than a large application of N for first cut now thus delaying the cut date. Finally, Mark spoke about the need to follow up on problem cows ahead of the breeding season as it is creeping up on farmers now. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

For this week’s Grass10 grazing management update, John Maher explains why a flexible approach has to be applied on farm to begin the 2nd rotation and particular caution needs to be taken on farms that are starting the 2nd rotation to ensure AFC stays above 650 kg DM/ha. Walk the farm on a more regular basis as growth increases.  Average farm cover needs to stay above 650 kg DM/ha.  Take action by reducing demand if your cover drops below 650 kg DM/ha. Meanwhile, the featured farmer is Michael Leahy from Co. Kilkenny. Read more from this week’s Grass10 newsletter and subscribe for weekly updates at:https://bit.ly/Grass10-7thApril   For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Water quality continues to be a major focus for the agricultural industry, and while farmers are already making changes on farm, there is increasing emphasis on how practical actions can improve water quality outcomes at catchment level.  In this episode, Pat Dillon from Teagasc joins James Dunne to discuss the Better Farming for Water campaign.  Pat explains what the Better Farming for Water campaign is aiming to achieve, why a catchment approach has been taken and the practical actions dairy farmers can take to make a difference.  We also discuss concepts such as nitrogen use efficiency, nitrogen surplus, stocking rate and how all of these interact with water quality. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

For this week’s Grass10 grazing management update, John Maher discusses why, due to the challenging conditions in spring 2026, a flexible approach has to be applied on farm to begin the 2nd rotation. By early April, dry farms should have about 60 units (75 kg N/ha) of N applied (combination of fertiliser and slurry) and most farms need to assess regrowths on the first 3 paddocks grazed for the next 2-3 weeks. Meanwhile, the featured farmer is Kieran Kennedy from Nenagh, Co. Tipperary. Read more from this week’s Grass10 newsletter and subscribe for weekly updates at:https://bit.ly/Grass10-31stMarch   For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Prof. Donagh Berry, Quantitative Geneticist at Teagasc Moorepark, joins Stuart Childs on this week’s Dairy Edge to discuss the future of Irish Dairy Breeding Programmes. Donagh first explains that breeding is all about numbers. With the uptake in use of sexed semen, the pool of dairy bull calves being born has shrunk and while this was part of the objective of using it in the first place, there is a side effect which has the potential to slow genetic gain in Irish dairy. He outlines the type of numbers of calves that need to be born each year in order to maintain the genetic growth that Irish farmers have enjoyed since the late 2000s when genomics arrived. In order to continue this, it will be important to have a structured breeding programme that will see Irish farmers work with the AI companies putting some of their best cows in calf to nominated bulls with a view to delivering the bulls of the future. Failure to do so will see the progress made in the industry in the last three decades since the introduction of the EBI slow significantly.  However, Donagh is attempting to avoid this occurrence by bringing industry together during 2026 to discuss the situation, identify the solutions and get them implemented as quickly as possible. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

For this week’s Grass10 grazing management update, John Maher discusses why monitoring grass supply on farm is critically important at this time of the year; growth rates are predicted to be above average for the coming week so walk the farm and establish regrowth on paddocks grazed first in spring. Plus, it’s important to get up to date with Nutrient applications – the aim is to have 60 units N/acre applied by early-mid April. Meanwhile, the featured farmer is Michael Cunniffe from Fuerty, Co. Roscommon. Read more from this week’s Grass10 newsletter and subscribe for weekly updates at:https://bit.ly/Grass10-24thMarch2026   For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com

Kevin Downing and Dan O’Riordan of ICBF join Stuart Childs on this week’s Dairy Edge to discuss the Spring Breeding Guidelines that will be arriving to farmers across the country this week. Kevin explains how the scorecard included in the guidelines can be used to identify the herd strengths and weaknesses to allow people to see where they may need to target improvement. He then discusses the importance of using enough dairy AI straws to ensure there are adequate numbers of replacements coming through to support the needs of individual farms. 25% is required in order to ensure that 18-20% replacement rates can be maintained as not all heifers will go the distance so some surplus will be needed. He also spoke about the importance of using high DBI with high beef subindex beef sires to generate high quality dairy beef stock and emphasises the need to continue using AI until such time as there is sufficient bull power to meet demand. Finally Dan spoke about how sire advice is now available on the HerdPlus app which will facilitate more people to use it.  He highlights the benefits of sire advice, balancing milk and fertility, avoiding inbreeding and lethal mutations and maximising beef merit while minimising calving difficulty risk, all making life easier for everyone involved. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com
