USING dairy young sires for progeny testing across all age groups now advocated by Cogent.

Young sire semen was supplied on the basis of use on 90% of all milking heifers, says Cogent. But there is now evidence to suggest that using young sires across other age groups still yields high quality data for reliable UK proofs. It will pay for breed society registration and first classifications of Cogent-sired daughters.

COGENT has signed a full collaboration agreement with XY, the US-based company, which has exclusive rights to the semen sexing technology recently acquired by Cogent.

That means Cogent will now be able to train and exchange staff with XY and pool resources, with the aim of commercialising sexed semen as soon as possible.
