Leviticus 22:26

Either a bull or a lamb that has any deformity or lacking in his parts, that you may offer for a free will offering; but for a vow it shall not be accepted.

You must not offer to the LORD that which has its testicles bruised, crushed, broken, or cut. You must not do this in your land.

You must not offer any of these as the bread of your God from the hand of a foreigner, because their corruption is in them. There is a defect in them. They shall not be accepted for you.’”

“When a bull, a sheep, or a goat is born, it shall remain seven days with its mother. From the eighth day on it shall be accepted for the offering of an offering made by fire to the LORD.

Whether it is a cow or ewe, you shall not kill it and its young both in one day.

“When you sacrifice a sacrifice of thanksgiving to the LORD, you shall sacrifice it so that you may be accepted.
