Sexed semen is now available from eight Holstein bulls in Bullsemen.com’s current “Minimum Standards” catalogue, with all meeting the company’s “no holes” philosophy of at least £130 PLI, +200kg milk and +1.0 of type.
Included in this new sexed semen offering are the German-proven Gibbon son Gibor – who climbs to 12th in the April 2008 bull proofs having been the highest ranking new entrant in the January listings - and several bulls from the major American co-operative CRI including Dillon and Stopper.
According to Bullsemen.com managing director Nick Kirby, the company’s approach to sexed semen is an extension to its overall approach of marketing the highest quality without compromise.
“There is arguably no better bull than Gibor currently available as sexed semen,” he says. “He has over 7000 milking daughters in Germany and now has a UK PLI of £197 and a Type Merit of +1.45. With a Lifespan of +0.6 and a really good SCC PTA of -21% this bull offers outstanding value whether sexed or not.
“CRI is maintaining a dedicated approach to sexed semen through its Genchoice facility whereby bulls are selected for sexing not only on sperm quality but also on genetic quality. All the selected sires have to be in the Top 20% for Lifetime Net Merit which is the US equivalent to the UK’s £PLI index.
“Overall, we are looking to supply sexed sires that will deliver a good level of genetic improvement and that can be used across a group of heifers to improve overall type on commercial dairy units.”
CRI Genchoice bulls currently on offer as sexed semen through Bullsemen.com include Convincer son Be Ware Convincer Dillon who has a PLI of £163 and a Type Merit of +1.05, and the Bellwood Marshall son Fustead Stopper who is a good all round type and production bull with a PLI of £136 and Type Merit of +1.37.
