ויקרא פרק כה , ז וְלִבְהֶּמְתְךָ וְלַּחַּיָׁה אֲשֶּר בְאַּרְ צֶּךָ תִהְיֶּה כָׁל-תְבוּאָׁתָׁהּ לֶּאֱכֹל:
מסכת פסחים דף נב/ב אמר קרא ולבהמתך ולחיה אשר בארצך כל זמן שחיה אוכלת מן השדה האכיל לבהמתך שבבית
כלה לחיה אשר בשדה כלה לבהמתך מן הבית
Food is only permitted to the owner of the field for the family’s consumption while the food is available in the fields for the wild animals to eat; after that time, a person must destroy any such stored food. This concept is derived from the cited verse since the word לבהמתך is extra. The basic law is concerning that the undomesticated animals must have access; the domesticated animals are the owner’s responsibility to feed. However, the extra word equates the domesticated animal to the undomesticated animal limiting the time one can feed the domesticated animal to the same time period that the type of food is available to the undomesticated animal. And the same law would apply to the human consumption of such food.
