In a recent post you wrote that the prohibition of meat and milk applies only if the milk and meat are from kosher sources. Does that mean the prohibition of milk and meat doesn’t apply to a kosher animal not slaughtered properly (i.e. cow slaughtered wihout shechita)? Of couse, it isnt kosher for other reasons.
Milk and meat from kosher sources that are cooked together are forbidden regarding benefit, and therefor may not be fed to animals. If the meat or milk is from a kosher source (e.g. a cow) that has not been properly slaughtered benefit from the mixture is forbidden as well. If the milk or meat are from non kosher animals the mixture is only forbidden for human consumption, but may be cooked together and benefit may be derived, including feeding it to animals.
