תּוספֿתּא אויף דברים 14:5

Five things were stated about a wild ox: It is forbidden [to slaughter on the same day as its calf] on account of "it and its offspring," and its fats are are forbidden, and it may be sacrificed on top of the Altar, and it is liable for the priestly gifts (i.e., the shankbone, cheeks, and maw), and it may be purchased with [second] tithe money for purposes of [bringing it as] a peace offering, but not for "meat for one's craving" (see Deut. 12:20). And behold, it is like a domesticated animal in every respect. Rabbi Yosei says, that is the t'o spoken of in the Torah (Deut. 14:5), and it is permitted on account of "it and its offspring," and its fats are permitted, and it is disqualified from being sacrificed on top of the Altar, and it is exempt from the priestly gifts, and it may be purchased with [second] tithe money for "meat of one's craving," but not for [purposes of] bringing as a peace offering, and behold, it is like a wild animal in every respect. And the Sages say, a t'o is a creation in and of itself, and a wild ox is a creation in and of itself.
