Sexed semen giving 75% heifers has significantly outsold other sexed bulls in the Bullsemen.com stud during its first six months of availability, representing 85% of total sexed semen sales.

This instant popularity, backed by comments received from hundreds of dairy farmers interviewed by Bullsemen.com’s breeding advisors, is a clear indication that this innovative approach to semen sexing is delivering an effective herd replacement solution, says the company.

“G75 sexed semen stems from a new manufacturing process that enables more product to survive with little damage, therefore allowing better quality bulls to be sexed at significantly less cost to the farmer than conventional sexed semen,” says Bullsemen.com managing director Nick Kirby.

“This allows us to market a bull of very high calibre for half the price that he is as conventional G90 sexed semen, and only marginally more than his cost as non-sexed

“From the feedback we are receiving, a 75% heifer return rate is adequate for most dairy farmers’ replacement requirements. The G75 sexed semen is therefore a very cost effective way to guarantee heifers without compromising on genetic quality.”

Bullsemen.com has announced the availability of Co-op Oman LOGAN as its next G75 sexed Holstein bull. Logan emerged from the January 2010 Holstein proof run as a leading improver for £PLI, production and milk components and now ranks as the best value Oman son currently on the UK market.
