[QUOTE="shloh1981, post: 746240, member: 12930"] Wondering a few things about lice. Before we got our latest bull (black angus bull from my best friend's dad's herd we bought three years ago as a yearling) I never noticed any infestations of lice in our small herd (4-5 momma cows). Last year in the early spring the bull started showing signs of lice (big bare spots of skin on his neck, tailhead, etc.). My friend's dad told me that sometimes his cattle get lice on their faces but it usually clears up after a while. Last year when I noticed it on the bull I used Ivomectrin pour-on on him and it cleared up right away. None of the other animals including the cows and the younger bulls that I was running the bull with at the time have ever shown signs of lice. Today I noticed the same thing with the bull (now a big four year old) but still no sign on any of the rest of the herd. We are miles away from any other cows. My dad mentioned that he thought lice could be spread by birds but so far in my limited research on the web it seems like lice are specific to certain types of animals. Anybody else have similar issues where only one or two animals show signs of infestation? I also read that some animals can have some immunity towards lice. Maybe the lice live in my herd but at levels that don't show on the cows but come on the bull in the late winter/early spring. Any thoughts on this topic would be greatly appreciated. Thanks!
