what is a stallion horse
Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, cresty neck, as well as a somewhat more muscular physique as compared to female horses, known as mares, and castrated males, called geldings.illies usually soon join a different band with a dominant stallion different from the one that sired them. Colts or young stallions without mares of their own usually form small, all-male, bachelor bands in the wild. Living in a group gives these stallions the social and protective benefits of living in a herd.
