Chullin 19 - May 19, 3 Sivan

Pictures Rav Nachman permitted slaughtering above the large ring, at the point where the "hat" begins to slope inward, provided that the chitim (wheat-shaped glands) are at least partially left intact below the cut. This ruling matches neither the rabbis nor Rabbi Yossi b'Rabbi Yehuda, but appears to follow the position of Rabbi Chanina ben Antignus. Rav Huna and Rav Nachman dispute the exact parameters of the disagreement between the Sages and Rabbi Yossi b'Rabbi Yehuda. One view posits that they disagree in a case where the slaughterer cut the first third too high up, and the remaining two-thirds in the correct place - whereas if one cut two-thirds in the correct place and then veered upward for the last third, all agree it is valid (as the majority was already severed properly). An alternative version shifts the opinions between Rav Huna and Rav Chisda. Both versions include a difficulty and resolution exchanged between either Rav Chisda, Rav Yosef, and Abaye. Rav Huna and Rav Yehuda further disagree on cases of alternating validity - such as when one slaughters the first third in the wrong place, the next third in the right place, and the final third in the wrong place (or the reverse scenario). Rav Yehuda follows the absolute majority; if the total sum of the valid cuts constitutes a majority, the slaughter is kosher. Rav Huna, however, evaluates the chronological moment the majority is achieved, requiring the majority to be made continuously in a valid manner. Rav Kahana asked Rav Yehuda for the ruling on the cases of alternating thirds. He then raised several subsequent queries regarding the validity of shechita performed over a pre-existing perforation (nekev) in the windpipe. The Mishna notes that the location for shechita is the exact opposite of the location for melika (the sacrificial pinching of a bird's neck). Melika must be performed from the back of the neck (oref), whereas shechita must be performed from the front or the sides of the neck.
