So Binyamin and I have been going over חולין פרק ראשון Hulin Perek Rishon. The משנה Mishna talks about שחיטה Shehita (Kosher Slaughter), which is prohibited on Shabbat. But, according to the משנה Mishna, if one does שחיטה Shehita on Shabbat, the שחיטה Shehita is Kosher.
The משנה Mishna doesn't go into any detail about when it can be eaten, though. So the גמרא Gemara starts off with רב Rav saying that, while the שחיטה Shehita is kosher, the meat isn't permitted on that day -- meaning that you can't eat the meat on שבת Shabbat.
Later on, the tables discuss a מחלוקת (Mahloket) in a ברייתה Breita that I mentioned in a previous post in this blog about what three different Rabbis say about cooking on שבת Shabbat, but this is about שחיטה Shehita on שבת Shabbat...
Later on, the גמרא Gemara talks about a time when the תנא Tanna (the man in the Yeshiva who remembered everything that was said in the Yeshiva word for word) was talking and רב Rav silenced him. So they are trying to figure out why רב Rav silenced the תנא Tanna.
The תנא Tanna said: המבשל בשבת בשוגג יאכל במזיד לא יאכל (one who cooks on Shabbat [if it is] accidental he can eat it [if it is] on purpose he may not eat it) -- (Which is what רבי מאיר Rabbi Meir said in the ברייתה Breita) --
רב נחמן בר יצחק Rav Nahmon Bar Yitzhak said that the תנא Tanna spoke about שחיטה Shehita and רב Rav says the table (the one I mentioned earlier) was about בישול Bishul (cooking) only and not about שחיטה Shehita. When it comes to שחיטה Shehita, רב נחמן Rav Nahmon says, all agree that you can't eat it on שבת Shabbat (that is, if someone slaughters an animal on שבת Shabbat, as the משנה Mishna says, the meat is Kosher but you can't eat it until after שבת Shabbat).
משנה: "שחיטה בשבת כשרה"
רב אמר: "אסורה לאכילה ליומה
The Mishna says "Slaughter on Shabbat is Kosher"
Rav says "It is forbidden to eat it [the meat slaughtered on Shabbat] on the day [meaning Shabbat]"
So the next suggestion about why רב Rav silenced the תנא Tanna is that perhaps it was because a live animal is מוקצה Muktza on שבת Shabbat and this made the whole שחיטה Shehita on שבת Shabbat issue quite different from the בישול Bishul on שבת Shabbat issue (since the food isn't מוקצה Muktza on שבת Shabbat as the live animal is). This, too, was discarded as a reason.
Finally, they suggested that perhaps the reason רב Rav silenced the תנא Tanna was that the תנא Tanna had said that if there is a חולה Hola/e (a sick person) then the animal can be slaughtered on שבת Shabbat and the meat can be eaten. But, because he was talking to the populous at the time, not the learned assemblage, the distinction of there being a חולה Hola/e might escape them, so Rav silenced the תנא Tanna so the populous wouldn't be confused. If there is no חולה Hola/e, then all agree that you can eat the meat on שבת Shabbat is
