How many doe can a buck mate in year?

There's no set number of does a buck can mate with in a year. It depends on a few factors:

* The buck's age and health: Younger bucks are often less successful at mating than older, experienced bucks. A buck's overall health and stamina also play a role.

* The size and density of the doe population: If there are many does in the area, a buck might be able to mate with more.

* The mating season: Bucks are most fertile and active during the rut (breeding season), which typically lasts several weeks.

However, it's important to note that:

* Bucks can mate with multiple does: A buck's natural instinct is to mate with as many does as possible to ensure the continuation of his lineage.

* The number of successful pregnancies is different: Even if a buck mates with many does, not all will become pregnant. Factors like the doe's health and age also influence pregnancy success.

So, while there's no definite number, a healthy, dominant buck in a large, dense population could potentially mate with dozens of does during the rut.
