CHULIN 31-43 - Two weeks of study material have been dedicated by Mrs. Estanne Abraham Fawer to honor the Yahrzeit of her father, Rav Mordechai ben Eliezer Zvi (Rabbi Morton Weiner) Z'L, who passed away on 18 Teves 5760. May the merit of supporting and advancing Dafyomi study -- which was so important to him -- during the weeks of his Yahrzeit serve as an Iluy for his Neshamah.


1. A dangerously-ill animal is Kosher only if it moves a foreleg and hind leg when it is slaughtered, according to Raban Shimon ben Gamliel.
2. Rebbi Elazar maintains that if blood shoots out from the neck of the dangerously-ill animal during Shechitah, it is sufficient to make it a valid Shechitah.
3. The Chachamim maintain that an animal must move either a foreleg or a hind leg in order for the Shechitah to be valid.
4. The prohibition of Neveilah and Tereifah takes effect, in addition to the prohibition of Chelev.
5. If a live animal was cut into two at its width, it is a Neveilah.
6. An animal is regarded as dangerously-ill when it stands on its feet and cannot remain standing, even if it is still strong enough to eat slats or chips of wood.


1. If it does not move a leg, then it certainly died before the end of the Shechitah.
2. One slaughtered a dangerously-ill animal at night and could not see whether or not blood shot out from its neck. If, the next morning, he finds the walls to be full of blood, then the Shechitah is valid, according to Rebbi Elazar.
3. This law applies to both small and large animals. However, if a dangerously-ill small animal extended its foreleg at the end of the Shechitah but did not bring it back towards its body, the Shechitah is Pasul, because it is usual for a small animal to extend its foreleg at the end of the Shechitah and it is no proof that the animal did not die before the end of the Shechitah.
4. The concept that one prohibition cannot take effect on another prohibition does not apply, and one who eats from the Chelev of a Tereifah or Neveilah is liable for both prohibitions.
5. Even if it is still moving, it is regarded as a Neveilah immediately when it is cut.
6. Since it cannot stand, it is considered dangerously-ill. If it is slaughtered, it must move one of its legs in order to be considered Kosher, according to the Chachamim.
