Oman son Logan has risen to third in the £PLI rankings following the August bull proof run, making him the top Holstein bull to be available to UK dairy farmers as sexed semen.

Logan is priced at just £22/straw by as the innovative GenChoice 75 (G75) sexed semen product, which offers dairy farmers a 75% heifer return.

Co-op Oman Logan emerged from the August Holstein proof run with an improved PLI of £226 (up from £200 PLI), and with significant increases in his production (now 835kg), lifespan (now +0.4) and Type Merit (+0.79) figures. He is also a somatic cell count improver with a score of -18.

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

“As a son of O-Bee Manfred Justice out of a BW Marshall dam, 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 £19/straw, and for dairy farmers seeking a minimum 75% heifer return his price is just £3/straw more. This really is a very cost effective way to gain access to the outstanding Holstein genetics of the current era.

“Logan’s improvement in consecutive UK proofs is a reflection of the fact that his daughters improve consistently as they move further into their lactation, and the positive trend is repeated around the world. He is highly ranked in the US TPI, rising in the latest proof run there from 2059 to 2088, and in Germany he is now the number one bull in the RZG rankings.”
