How many straws are required for one insemination dose?
A breeding dose prepared by an SBS Affiliated Laboratory is standardized to comprise of eight 0.5mL straws. Semen is frozen at a concentration of 200-250 million/mL, resulting in a total of 800 million to 1 billion sperm in a final dose volume of 4mL. Given our minimum recommended post-thaw motility for commercial distribution of 30% progressive, each breeding dose therefore also exceeds the industry recommended minimum of 200 million progressively motile sperm per dose after thawing.
