Negative Commandment 217 (Digest)
Interbreeding Animals

"You shall not let your cattle breed with a different kind"Leviticus 19:19.

It is forbidden to breed together two different animal species.

Negative Commandment 218 (Digest)
Working with Two Animal Species

"You shall not plow with an ox and donkey together"Deuteronomy 22:10.

It is forbidden to cause animals of two species to work together, e.g., to have them jointly plow, thresh or pull a wagon.

Biblically, this prohibition only applies if one of the animals is kosher (e.g., an ox) and the other of a non-kosher species (e.g., a donkey). The Sages, however, extended this prohibition to apply to any two species.


Translation of (the unabridged text of) Sefer Hamitzvot by Rabbi Berel Bell, member of the Rabbinical Court of Montreal and director of Teacher Training for the Jewish Learning Institute.

From "Sefer Hamitzvot in English," published by Sichos in English.
Daily Quote
If you follow My statutes and observe My commandments and perform them: I will give your rains in their time, the land will yield its produce, and the tree of the field will give forth its fruit. Your threshing will last until the vintage, and the vintage will last until the sowing; you will eat your food to satiety, and you will live in security in your land. And I will grant peace in the land . . .
  –Leviticus 26:3–6
