Castration and dehorning of cattle is the common practice in the cattle industry. This a violation a basic Noahide Law ref Tractate Sanhedrin 56a-b:

שבע מצות נצטוו בני נח ...רבי חידקא אומר אף על הסירוס Seven commandments were given to the sons of Noah... Rabbi Chidka said they were also commanded not to castrate animals.

All men today that are Bnei Noah are required to follow this command. I refuse to castrate and dehorn my cattle and get a big reduction in sale price for them at the local sale barns. Most of all male slaughtered animals in the US have been castrated, dehorned if not polled by mixed breeding and then fattened on Kilayim-(mingled seed) (GMO) feeds with herbicide residues. Why are these animals slaughtered as kosher beef?


Castration of an animal is forbidden to Gentiles (according to most opinions) so a Jew cannot tell him to do so. If he does he is forbidden to eat that animal. But if the gentile has already castrated the animal it is permitted for a Jew to eat that animal.

The Shulchan Aruch Even Haezer 5,14 says:

אסור לומר לכותי לסרס בהמה שלנו. ואם לקחה הוא מעצמו וסרסה, מותר. ואם הערים ישראל בדבר זה, קונסין אותו
It is forbidden to tell a Gentile to castrate an animal, but if he did so himself it is permitted to have benefit from. But if the Israelite told the Gentile to castrate the Animal we punish him that he cannot benefit from the animal

Chelkas Mechokek

ישראל אחר מותר לאכול אף על גב שהוא בכלל תעבתי לך מ"מ מדאסור לגבוה ש"מ להדיוט שרי מרדכי פ' ש"ש וישראל שסירס או שסירס העכו"ם בשבילו משמע דאסור לאכול ממנו
We punish him since he told the Gentile to castrate the Animal or castrated it himself he cannot eat it, but not other Jews that didn't tell the gentile to castrate the Animal i.e they can eat that animal if it was Slaughtered properly.

A Gentile is not commanded regading Kilayim (cross breed) seeds rather only kilayim fruit from a tree and Kilayim animals (mixtures) Rambam Melachim 10,6:

מִפִּי הַקַּבָּלָה שֶׁבְּנֵי נֹחַ אֲסוּרִין בְּהַרְבָּעַת בְּהֵמָה וּבְהַרְכָּבַת אִילָן בִּלְבַד
A Noachide is commanded not to crossbreed animals and trees

So since a gentile can feed his animal_kilayim_ GMO seeds, that animal is permitted for a Jew as there is no reason to punish the Jew with a Knas as no transgression has happened.
