What is an insemination dose?
Good question. Some Stallion Stations package 800 million sperm per dose. These sperm can be packaged in just a few large 5ml straws or in as many as 12 small (0.25ml) straws. Usually, though, the semen is packaged in six to eight 0.5ml straws. Regardless of the number of straws per dose, there should be enough semen for one ovulation cycle. Many veterinarians will thaw half the straws in the dose to inseminate just before ovulation and the other half to inseminate just after ovulation.
