Not knowing anything about leukosis, I looked it up. Here is a section of the Merck Vet Manual on leukosis. You might want to read the sections on spread and prevention. It looks like something that could spread "horizontally" or "vertically" through your herd. Seems like something the breeder you bought from needs to get this cleaned up before he sells any more cattle and spreads it. The article says 44% of all dairy cows have it but only 10% of beef. Good luck. |
