Miniature Horse Sexual Preference

While scientific studies are non-conclusive, it appears that horses have distinct sexual preferences and that horse homosexuality and bisexuality is more related to environment than to genetics.

Horse Sexual Preference

It is well-documented in horse breeding that stallions have very clear sexual preferences for their partners.  Many breeding stallions have color preferences for their mare's, and colored blankets must be used.  For example, a Bay Stallion may refuse to breed a gray mare and a brown blanket must be placed on the mare in order to pasture breed. 

Stallion Bisexuality

Bisexuality is prevalent in bachelor stallion groups that have no access to mares.  Without access to heterosexual activity, many stallion will engage in typical homosexual activity, mounting other stallions and adopting mare-like heat display to entice other stallions.
