Halakhah sa Deuteronomio 11:15: Shulchan Shel Arba & Kitzur Shulchan Arukh

If one has said the blessing “ha-motzi’” and has a conversation in the interim before he eats, he says the blessing over again. But if the conversation is just something that has to do with the table, like “take it and say the blessing,” or “pass the salt or relish,” or even “mix some mush for my ox,” he does not have to repeat the blessing, since a person is required to give food to his livestock first, and after that eat, as it is said, “I will provide grass in your fields for your livestock” and then “you shall eat your fill.”⁷⁴Dt. 11:15. Thus it is something that has to do with the table and does not count as a break. It is like some one butchering a hundred chickens. If he talks between one butchering and another to say, “pass me some others,” it has to do with the butchering, and does not count as a break.

If you own animals or birds (poultry), and it is your responsibility to feed them, you are not allowed to eat anything until you feed them, as it is written (Deuteronomy 11:15): "And I will put grass in your fields for your cattle (animals) and you will eat and be satisfied." Thus the Torah has given preference to feeding the cattle [animals] before the feeding of man. But as regards drinking, man comes first as it is written (Genesis 24:14): [Rivkah said] "Drink first and I will also give your camels to drink." Similarly it is written (Numbers 20:8): "And you will give drink to the congregation and to their animals."
