Bava Metzia 90 - May 28, 20 Iyar

Two contradictory sources are brought regarding the prohibition to muzzle an animal while the animal is threshing trauma and maaser produce. One source suggests it's not prohibited, while another asserts it is. Various explanations attempt to reconcile this contradiction, suggesting differences in the type of truma/maaser or differing opinions. If the food on the threshing floor is causing the animal to be sick, is it still prohibited to muzzle - is the prohibition meant for the best interest of the animal or is it meant to not be cruel to the animal? Is it prohibited to tell a non-Jew to muzzle the animal and thresh with it as with laws of Shabbat or is it forbidden only on Shabbat on account of the stringency of Shabbat laws? Two sources are brought to answer this question, but in the end are not conclusive. Rami bar Hama asks a series of questions about whether there is a prohibition of muzzling in a case where there is some external factor that is in place (not put there by the owner) that may prevent the animal from eating. His questions remain unanswered. Rabbi Yonatan asked if one muzzled another's animal and then brought it to the threshing floor, is that forbidden? Rabbi Simai answered from the case of kohanim coming into the Temple drunk that obviously, the verse did not mean only when drinking as one goes into the Temple. If one person muzzles and the other brings it to thresh, the second one gets lashes. Rabbi Yochanan and Reish Lakish debate about whether one gets lashes for muzzling an animal by words alone, i.e. telling the animal not to eat.
