How many cows per bull?
Jami2023-02-06T02:15:24+00:00A bull can breed 25 cows on average per year. Some bulls cover more cows. However, over a long period of time, if you don’t have enough bulls for your cow herd size you could have many open (non-pregnant) cows. Overworking a bull leads to decreased sperm count which could temporarily or permanently affect a bull’s fertility.
