Okie so my 32 month old Brangus bull has been out with 10 cows breeding since May26. Some being replacement heifers and the majority being mature brangus and angus cows. 3 weeks ago I noticed my bull limping on his left hind leg much resembling a horse with an abcess. Not putting his full weight on but still getting use out of the leg and foot. He arches/cocks his fetlock much like a horse when they rest there hind legs. He tends to stay on toes. So after 1 week and half the vet comes and we lay the bull down in the pasture to doctor a superficial case of pinkeye due to a seed. The vet decided to examine the leg. There was no foot rot no soreness in the hoof or toes. He checked for a stifle injury and there was no swelling. No swelling anywhere in the bulls leg. My vet told me if it were in the hip the swelling would not show, but in this bulls case he didnt think it was in the hip because the bull was not swinging his leg out. The bull walks in a straight line with the hurt leg following right in step with the front. Now about the bull....He has continued to use this leg to the fullest extent. I have seen him mounting, and breeding cows mulitple times. He is breeding hard even with this slight injury. Ive also seen him run several times to feed with the rest of the herd. A wide open gallop. He does not lag behind, he doesnt really lay around alot and rest he's very active and as I said he's still fullfilling his duties and doing quite well. Im just worried what this is and will it eventually pass? I did notice today that the bull was actually kind of dragging his toes on that foot now, but he also was tracking cows heavy today....maybe I was just looking to hard today. Ive contacted the breeder and they told me to keep them updated if they need to replace the bull. But I really like this one and thats to much traveling seeing how the bull came from far away. Please give me some incite to what this may be. Ive had several other old timer, good cattlemen tell me that its not a stifle injury cuz the bull would be doing nothing whatsoever and could not mount or breed cows let alone run. Thanks alot for any help!!
