MBY 332:1-4 Laws relating to birthing and healing animals on Shabbos (abridged)MBY 332:1-4 Laws relating to birthing and healing animals on Shabbos (abridged)
[Based heavily upon Kitzur Shulchan Aruch: 87:22-24, “Metsudah” edition, with notes, translated and annotated by Rabbi Avrohom Davis] 22) You must not deliver an animal of its offspring on Shabbos. Even to assist it, i.e. holding the newborn so that it should not fall to the ground, is forbidden. (Footnote #45: Where there is danger to the life of either animal – mother or offspring – you may ask a non-Jew to aid in the delivery. If there is none available, you may help in the delivery. Chazon Ish 59:5, see also Pri Megadim 332:2)
23) On a fresh wound which is causing the animal pain, you may apply oil; but on a wound that is healing, and applying oil is only for the comfort of the animal, it is forbidden. (Footnote #46: It is considered an unnecessary and bothersome activity. Shulchan Aruch 332:2)
24) If an animal ate too much vetch, or the like, and is now suffering, you may cause it to trot in the yard in order to exhaust it so that it should recuperate. (Footnote #47: The prohibition against administering remedies does not apply to animals - Rif and Rosh.) If the animal has become hyperemic (i.e. suffering from an increase in blood), you may make it stand in water so that it will cool off. If there is a possibility that if it is not bled, it may die, you may tell a non-Jew to bleed it. (Footnote #48: Mishnah Berura and Chayei Adam permit instructing a non-Jew to blood-let even to alleviate pain or illness.) Other remedies should also be administered through a non-Jew.
