[QUOTE="Dempster, post: 1513618, member: 32761"] Nuflor is commonly used in bulls with foot/hoof diseases, in-spite of the label precautions. It is not unusual that your vet did that. However, everything else your vet did was unusual. A 900 # bull should receive about 40 cc of LA 200, not 15, if giving a standard sub-q dose. Additionally, banamine can be given at 1-2 ml/100#, the 2ml/100 dose is probably a lot more common than 1, I would of thought the vet would of given closer to 18 of that, but 10 is still within the labeled dose. I'm going to take a stab in the dark and guess that this vet does a fair bit of horse work, not as much on cattle. I don't know that I would expect epididymitis to cause a noticeably enlarged scrotum, the epididymis is a relatively small portion of the testicular structure, but maybe you would see a little enlargement. Additionally, lots of bulls go through a bout of epididymitis, end up with a hard epididymis, and continue to have acceptable fertility. It is possible that side shuts down and the other testicle takes over total production, but there are also bulls out there where both epididymis are hard and they are still fertile. Given the significant enlargement and subsequent shrinking of the scrotum, it is more likely the testicles underwent some severe stress prior to your vet visit that caused the enlargement and ultimately caused them to shut down, which is why they shrunk and the bull is no longer fertile. It's not likely your vet did anything to contribute to this process, and there probably wasn't much else they could of done to prevent it. A scrotal measurement at each visit would of been interesting to track. [/QUOTE]
