Puberty is a transitional period for horses, from a time of reproductive immaturity to a time where sexual behavior is demonstrated and sperm is ready for release in the colt, and the filly starts to cycle. Unfortunately, very little information is available about puberty in horses, including at what age and what weight most horses reach this important li...
