Hello, I'm an expert in animal husbandry and livestock management. When it comes to the question of how many cows a bull needs, it's important to clarify the context. If you're referring to a breeding situation, the number of cows a single bull can effectively service depends on various factors such as the bull's age, health, and the management practices in place.

In a well-managed cattle operation, a young and healthy bull can typically breed with a group of cows that ranges from 20 to 30, depending on the time of the year and the specific breeding program. However, this number can vary widely based on the bull's libido, the cows' receptiveness, and the level of supervision provided by the rancher.

It's also worth noting that overbreeding a bull can lead to a decline in the quality of his offspring, so it's crucial to maintain a balance that ensures the health and productivity of both the bull and the cows.

However, a breeding soundness exam must be done 30-60 days prior to bull turn out.read more >>
