How Many Straws Are In a Dose?

How many straws are in a dose? The number of straws in a breeding dose can be highly variable within the industry. For some stallions, there may be doses on the market that are 1, 2, 3 or 4 straws/dose, typically based on post-thaw motility of that lot and the recommended breeding dose of 200 million progressively motile sperm.

But what happens if a straw cracks or is damaged 😱, or you don’t have access to a vet with advanced techniques such as deep horn insemination? Can you trust 🙏 that your mare is getting what she needs to actually achieve pregnancy? Does your anxiety level go ⬆️ as the number of straws goes ⬇️?Select Breeders Services and their affiliate labs have standardized all doses to be comprised of 8 straws, regardless of post-thaw motility. This way when you receive 8 straws you know you have a full dose. SBS 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.This allows breeders to trust that each dose exceeds the industry minimum of 200 million progressively motile sperm per dose after thawing. In addition, the 4 mL breeding dose is more forgiving and flexible for the average breeder to work with and use without having to rely on advanced techniques or vets.
