Semen production takes ten weeks, so MOT your bull now to ensure he is ready to go to work when the breeding season starts. He should be fit not fat, and have a body condition score of 3.5 at the start of the service period to ensure his optimum performance.
Bull fertility is key to maintaining a compact calving period, maximising the value of the calf
crop and overall herd profitability. While few bulls are infertile and therefore incapable of getting a cow in calf, many are sub-fertile and produce fewer calves than a fully fertile bull. Check scrotal tone and size, as testicle size has a direct influence on daily sperm production and hence mating load. The testicles should feel firm with no lumps, softness or swelling. His penis and sheath should be free of sores, scars and abscesses. Four weeks before serving, ask your vet to check his semen quality.
For a bull to actively seek out cows for mating and mount them he needs to be physically fit, possess good locomotion and be free from pain or discomfort. More bulls are culled for problems with their hind limbs than for any other structural condition, so check his feet and legs carefully.
