Mishnayot Zevachim 8:1-3 repeatedly prescribe the strategy of "יִרְעוּ עַד שֶׁיִּסְתָּאֲבוּ" - "they graze until they become defected" for dealing with animals that are stuck in situations of doubt with respect to whether they should be offered as korbanot. The idea is that the doubtful animal is left to graze until it develops a defect that invalidates it for offering. When that happens, it's legal to sell the animal to the general meat market and then use the proceeds to purchase whatever korban it may have been committed to.
I'm wondering how this strategy works, in practice.
- Are animals destined to be korbanot kept in safer conditions than general-market animals, while those in this יע"ש situation are kept in regular conditions?
- Are animals destined to be korbanot kept in the same conditions as general-market animals, while those in this יע"ש situation are kept in worse conditions?
- Are all animals kept in the same conditions, and we assume it's just a matter of time until they develop a defect?
In any case:
- Is there a standard period of time, under יע"ש conditions, within which it's expected that an animal will develop a defect, or is there a wide distribution for this duration, such that many such animals pasture for the rest of their lives?
