[QUOTE="cowgirl_jenna, post: 996169, member: 20102"] Its fairy common in dairy herds in spots. Probably more common in beef herds than we realize. The thing is, you notice it mostly when an animal is "pushed hard in a high production environment"... The exact words of a dairy cow. I feel some beef cows may have/carry it, but it is not nearly as apparent due to beef cows aren't pushed as hard as dairy. I do believe there were some funding/grants at one point to get your herd tested and eradicate it. Basically its a bad disease, that costs ?millions? (maybe more) $ a year in loss of production. With that said, you can get rid of it, but it'll take time. I know of a few dairy guys that tested everything, only used milk re-placer for calves, as colostrum/milk is a great way to transfer it to the newborn calf. It took many years, but I think they are free of it at the moment. You really have to watch purchased cattle, as one animal can infect some of or your whole herd. [/QUOTE]
