During the winter I didn't deworm my boer goats that often. They were pregnant and I gave them a shot of Ivermec once and fed them a couple bags of the Postiive Pellet Dewormer. A couple of days ago I noticed bottle jaw starting to form on one of my does already. She is one that I purchased in January so she did not get the Ivermec shot I gave my other girls, but did get the Positive Pellet Dewormer. So anyway, just a heads up .... it is time to hit those boer goats hard again with the dewormers and keep it up so she don't have problems like we did last year. I have dewormed mine with Cydectin and the one with the bottle jaw I waited 3 days and dewormed her again with Cydectin. These 4 girls are all heavy bred and the other 3 were not showing any signs of worm burdens but they got dewormed anyway.
