User blog:Stormzone5/Mutton Drops

I recently added a mod called realistic livestock, the mod replaces the models of the animals of the own minecraft

The problem is that when I kill a sheep, it drops meat from the mod rather than mutton from the LoTR mod. Is there any way to remove the meat from the realistic livestock mod and make the meat from the LoTR mod drop from the sheep?

ps: I looked in the configs and there is no way to disable the game.
