Shabbat 45B

פצעילי תמרה, לרבי שמעון מהו? אמר לו: אין מוקצה לרבי שמעון אלא גרוגרות וצימוקין בלבד.

Unripe dates that are placed in baskets to ripen and until they are ripe can only be eaten with difficulty, according to the opinion of R' Shimon, what is their legal status as far as moving them on Shabbat is concerned? Are they considered set-aside? R' Yehuda HaNasi said to him: There is only a prohibition of set-aside according to R' Shimon in the cases of dried figs and raisins alone.

ורבי לית ליה מוקצה? והתנן אין משקין ושוחטין את המדבריות, אבל משקין ושוחטין את הבייתות. ותניא: אלו הן מדבריות? כל שיוצאות בפסח ונכנסות ברביעה. בייתות ⁠— כל שיוצאות ורועות חוץ לתחום, ובאות ולנות בתוך התחום. רבי אומר: אלו ואלו בייתות הן. ואלו הן מדבריות: כל שרועות באפר, ואין נכנסות לישוב לא בימות החמה ולא בימות הגשמים.

The Talmud challenges this: And does R' Yehuda HaNasi not hold that there is a prohibition of set-aside? Didn’t we learn in a Mishnah that on a Festival, before they are slaughtered, one may neither give water to, in order to ease removal of their hides, nor slaughter wild, desert animals, animals that are always grazing in the fields? Since people do not generally tend to them, they are considered set-aside and may not be used. However, one may give water to and slaughter livestock. And it was taught in a baraita that these are wild, desert animals: Any animals that leave their sheds on Passover and only enter their sheds with the advent of the winter. livestock are any animals that go out to graze beyond the city limits, and come and sleep within the city limits. R' Yehuda HaNasi says: These and those are both domesticated. And these are the wild, desert animals that are prohibited due to the prohibition of set-aside: Any animals that graze in the grazing area and neither enter the town during the summer nor during the winter. It is these animals that it is prohibited to give water to or slaughter on a Festival. Apparently, R' Yehuda HaNasi holds that there is a prohibition of set-aside even in the case of animals.
