BULLPLUS™ PRODUCT DETAILS >  

BULLPLUS in a new semen sexing kit. Sexing of semen will never be easier. Everything needed for sexing a single straw of semen is freeze-dried in the mixing vial. It can be used with any bull or any frozen semen you already have in the tank. Semen is thawed as usual and mixed in the BULLPLUS vial. Incubate for 20 minutes and the sexed semen is ready for insemination.

How does it work? BULLPLUS works by "accelerating" the motility of only the Y-chromosome bearing (male) sperm while "reducing" the motility of the X-chromosome bearing (female) sperm. As a result, the male sperm arrive at the point of fertilization ahead of the female sperm. More ovum are then fertilized by the male sperm resulting in a higher percentage of males calves. There is no need to sort sperm mechanically; the gender-biased sperm are sorted in the reproductive tract of the cow.

Are pregnancy rates affected? Conception rates are excellent using BULLPLUS. Many producers are reporting improved conception rates!

Commercial producers: Beef production and returns from bull/steer calves can be 15-20% in excess of that of a heifer calf. Feeder calf producers will want to take a look at incorporating gender selection and BULLPLUS into their AI program. For a few cents on the dollar you can increase gross receipts up to 25%!

Seed stock producers: Whether you need more bull calves to sell, more male embryos to transplant, or want to incorporate gender selection into your breeding management decisions, BULLPLUS will help you plan and make better decisions.
