High Ranking Holstein Logan Now Available as 75% Sexed Semen

High ranking Oman son LOGAN is the latest Holstein bull to be made available by as the innovative GenChoice 75 (G75) sexed semen product, thereby offering dairy farmers a 75% heifer return from a leading sire for only £19/straw.

The chances of breeding a Logan daughter like Jaegar Logan 2158 can be cost effectively enhanced by using the new 75% heifer sexed semen product from this sire.

Co-op Oman Logan emerged from the latest Holstein proof run (Jan 2010) with an improved PLI of £185, placing him in the top dozen sires for this leading criterion, and with strong production (723kg), lifespan (0.2) and Type Merit (+0.96) figures. He is also a somatic cell count improver with a score of -20.

According to, Logan is currently the best value Oman son on the UK market.

“As a son of top PLI sire O-Bee Manfred Justice out of dam BW Marshall, Logan - who we source from leading US co-operative CRI - fully reflects his pedigree,” says managing director Nick Kirby. “He represents exceptional value at his conventional semen price of £16/straw, and now we are able to offer a product with a minimum 75% heifer return for just £3/straw more. This really is a very cost effective way to gain access to the outstanding Holstein genetics of the current era.

“We launched the G75 sexed semen product last autumn with Wa Del Ricecrest HOLMAN, and this quickly became a best-seller for It is a concept that dairy farmers like, because for most a 75% heifer return is sufficient for their breeding and replacement planning.”

The G75 sexed semen product is possible due to a new application by CRI of established technologies, which are already proven and applied in the successful GenChoice 90 (G90) sexed semen product. A significantly higher proportion of the product survives the sexing process when achieving a 75% heifer return, and hence the product is more affordable. Fertility for G75 is the same as for G90.

Logan is also available from as a G90 product at a price of £36/straw.
