Im looking for a discussion about this bulls loss of fertility. I got a shorthorn bull calf born July 2, 2016. Mid may 2017 I put him with 6 heifers. June 30 I went to preg check via blood draw the heifers. I found his scrotum swollen. Took to vet. Diagnosed epididymitis. Gave 15cc la200, 45 cc nuflor, 10cc banamine to a 900 pound bull. Took back 3 days later and had the la200 and nuflor but no banamine. 2 of the heifers came back preg on the first test. Mid August took a highland/shorthorn heifer we were going to show to get to get ears tattooed. Palpate preg test called her open. End of August put bull back with heifers. Oct 1 preg checked 4 that previous test called open. 2 came back preg including highland/shorthorn. One heifer open came down with hardware and was treated and sold. Other shorthorn still open. Left bull with her all winter. In march 4 heifers calves including the one that the vet called open in August. I took the open heifer and bull to a different vet as I have no confidence in first vet. New vet could not find a thing wrong with heifer. Tested bull. He had an almost zero semen count. I looked closely and his testicles were half the size they were a year earlier. I culled him. Then I had a baby heifer get sick. Decided to give her nuflor. First time I had given nuflor at home so I carefully read packaging. It says on the box and on the bottle not to give to breeding animals as it causes testicular degeneration. So I am wondering if his loss of fertility was caused by the infection or by the nuflor. It cost me a really nice registered bull. I love the couple of calves I got from him. I have not discussed this with either vet.
