Hadran: Advancing Talmud Study for Women

The dispute between Rabbi Natan and the rabbis regarding whether a secular slaughter requires intent has ramifications in the case of one who slaughters an additional animal during the slaughter of a para aduma (engaging in an extraneous activity). If slaughter does not require intent, the cutting of the second animal’s simanim is considered a completed act of slaughter, and consequently, the para aduma is disqualified because an extraneous activity was performed at that time. Conversely, if slaughter requires intent, the unintended slaughter is not considered an act at all, and the para aduma remains valid.

The disqualifications of shechita begin with the law of shehiya (pausing), which occurs when the slaughterer pauses between the slaughter of one siman and the next. A tannaitic dispute is analyzed regarding the duration of time that disqualifies due to pausing, questioning whether it is the time of an act of slaughter or the time it takes to examine the knife. Several amoraim define the duration of slaughter: Rav defines it as the time needed to slaughter another animal, while Rav and Shmuel dispute whether the disqualifying pause for a bird slaughter is measured by the time it takes to slaughter an animal or a bird. Additional opinions expand this duration to include the time required for physical handling of the animal, such as the time it takes to lower it to the ground or lift it and push it down.

The details of the disqualifications continue with ikur (tearing the simanim instead of cutting them) and chalada (inserting the knife beneath the simanim or behind them). These flaws in the act of slaughter trigger a tannitic dispute between Rabbi Yeshevav and Rabbi Akiva over whether animals disqualified by an improper slaughter, such as shehiya, chalada, or ikur, are considered a treifa and do not impart impurity, or whether they are treated as a neveila and impart impurity through carrying. Ultimately, Rabbi Akiva reversed his original understanding and agreed with Rabbi Yeshevav that the status of these animals is like a neveila in all regards.

A contradiction to the Mishna arises from a Mishna at the beginning of the third chapter, which lists a severed windpipe among the defects that define an animal as a treifa, seemingly contradicting our Mishna’s ruling that such a defect is considered a neveila. To resolve this contradiction, four potential resolutions are proposed, two of which are ultimately rejected.

The Gemara continues the debate over whether shechita takes effect continuously from the beginning of the act until the end (yeshna l’shechita mitchila ve’ad sof), or if it only takes effect at the very final moment (eina l’shechita ela basof). Two further difficulties are raised against the latter opinion and are resolved.

There is a debate about whether the shechita needs to be done in a single, continuous cut (shechita mefura’at) or can be done in two or three different spots along the neck. The Gemara raises two difficulties against those who require shechita mefura’at. These challenges are resolved.

Rav Yehuda in the name of Rav brings a ruling about chalada, a disqualification of shechita when the knife is hidden under the simanim. The Gemara tries to assess what he is adding which wasn’t already stated in the Mishna in Chullin 32a.

The second part of Rav’s statement was that if the knife is under the hide, the shechita is valid. However, the beit midrash of Rav (Bei Rav) stated that it was unknown whether he actually permitted it under the hide. This statement by the scholars of his beit midrash led to several related questions that remain unresolved (teiku), such as hiding the knife under a cloth, under tangled wool, or concealing it during only a minority of the cut.

A Mishna rules that slaughtering two heads at once or two people holding a single knife and slaughtering are both valid. However, completely severing the head in one instantaneous downward blow is invalid due to pressing (drisa). The Mishna qualifies this: if the person was actually drawing the knife back and forth, but it came off after just moving the knife in one direction, if the knife was long enough, the shechita is valid. If they slaughtered with a back-and-forth motion, even if the blade is very small, the meat is kosher.

Two sources are brought to support the need for moving the blade back and forth when slaughtering.
