Tim Brown: Differences in level of DCAD intensity
from Progressive Dairy Podcast Hosted by Walt Cooley
When prepartum cows are fed a negative DCAD diet, inducing a mild compensated metabolic acidosis, calcium status is improved, resulting in healthier, more productive cows. Recently, some nutritionist have been feeding even lower-DCAD diets (more anions) to acidify cows more deeply than the majority of published research. At these higher, more extreme levels of acidification, cows may walk a fine line between being OK and being overwhelmed by uncompensated metabolic acidosis. Progressive Dairy Editor Audrey Schmitz spoke with Tim Brown to hear more about DCAD myths and the optimum level for negative DCAD diets.
