Semen Collection

Typically semen is collected every two to four days; and depending on the stallion’s sperm production an average of 5 to 15 straws can be frozen per collection. Some stallions with large testes can produce 15 to 30 straws per collection. One straw can be one insemination dose when it contains a minimum of 300 million progressively motile sperm cells post thaw. We recommend supplying 2-3 straws of frozen semen per heat cycle per mare; and for booking purposes, sufficient semen should be on hand to cover a minimum of two cycles per mare.
