What is the ruling on giving a pregnant she-camel an injection to abort her, on the grounds that her pregnancy is from an undesirable male camel?

Aborting a pregnancy in an animal is permissible if there is a valid reason, and it does not take the same rulings as aborting a human fetus. However, it is conditional upon not torturing the animal or tampering with it. The reason mentioned in the question (that the camel becomes pregnant from an unhandsome male camel) is not a valid reason. Therefore, it should be avoided as it constitutes tampering with the animal.
