הַבְּהֵמָה מוּעֶדֶת לֶאֱכל פֵּרוֹת אוֹ יְרָקוֹת וְכַיּוֹצֵא בָּהֶן. לְפִיכָךְ אִם נִכְנְסָה לִרְשׁוּת הַנִּזָּק וְאָכְלָה דְּבָרִים שֶׁדַּרְכָּהּ לְאָכְלָם מְשַׁלֵּם נֵזֶק שָׁלֵם שֶׁנֶּאֱמַר (שמות כב ד) "וּבִעֵר בִּשְׂדֵה אַחֵר מֵיטַב שָׂדֵהוּ" וְגוֹ'. וְאִם אֲכָלָתָם בִּרְשׁוּת הָרַבִּים פָּטוּר. וְאִם נֶהֱנֵית מְשַׁלֵּם מַה שֶּׁנֶּהֱנֵית לֹא מַה שֶּׁהִזִּיקָה:
It is taken for granted that an animal is prone to eat fruit, vegetables or the like. Therefore, if [an animal] enters a domain belonging to another person and eats produce that it would normally eat, [the owner of the animal] is liable for the entire amount of the damages, as stated [in Exodus 22:4]: "And if he shall send forth his animals, and they shall pasture in another's field, payment should be exacted from his choice field." If [the animal] ate produce belonging to another person in the public domain, [the owner] is not liable. If [the animal] benefits [from eating the produce], the owner must pay for the benefit [his animal received], but not for the damages caused.
