Related Does one have to feed his dog, parrot, or goldfish before eating according to this Gemara?
The gemara in Gittin 62A teaches that one should feed his animals before he, himself eats. I have seen others who write that the care of an animal including feeding it satisfies tza'ar ba'alei chayim.
As the feeding of the animal is elevated to the role of "mitzvah" (that is, the fulfilling of an halachic obligation) does the food used get elevated in its sanctity as well (having been used for a mitzvah)?
As a practical application, my 4 minim, having been used for a mitzvah on Sukkot, have to be treated with a certain level of respect, and according to some, should be used for a mitzvah. Can I feed my lulav to a cow, or my etrog to whatever animal eats etrogim because feeding is a mitzvah?
And does the food left in my dog's bowl, which I set aside to be used to feed him (thus it was established there for the sake of a mitzvah) need to be disposed of in a particular manner because it has been elevated through its use for a mitzvah?
the fulfilling of an halachic obligation. If one wants to cut their tzitzis, the halacha obligates using one's teeth – robev Oct 24 '21 at 14:47fulfilling of a halachic obligation, then my example is included. If you mean only things that are actual mitzvos, for example the sign being it's counted in the 613 or one makes a blessing, then feeding of one's animals I would think would be excluded. As far as I know, it isn't counted as a mitzvah by any of the Rishonim, and only by Sefer Charedim (an early Acharon). If I'm not mistaken, the Rambam doesn't even mention it as an obligation in his Mishneh Torah. – robev Oct 24 '21 at 14:52And isn't tzaar baalei chayim at least a miderobonon mitzvahagain, depends what you mean by mitzvah. It's not included in the seven mitzvos derabanan that Rav Dovid Vital counts. In any event I believe we pasken tza'ar baalei chaim is a Biblical prohibition. Either way, it would seem feeding your animals first is simply a halachic obligation, as you wrote. If so, my example is included. – robev Oct 24 '21 at 15:07
