Joint sire scheme is 'breeders working for breeders'

"Breeders working for breeders" is how Taranaki farmer Wayne Taylor describes a joint sire-proving venture between Holstein Friesian NZ and CRV.

Milking 190 Holstein Friesian cows on 68ha effective on Waitara, Wayne and wife Leeanne's farming businsess Muritai Holsteins has three bulls included in the 2022 Holstein Friesian NZ Genetic Leaders team, a scheme they have supported since its inception in 1995.

"We have always had loyalty to supply bulls to the association' breeding scheme because it's breeders working for breeders," Wayne says.

"We have been fortunate enough to have had several bulls included in Genetic Leaders' teams over the years."

Genetic Leaders aims to prove young sires for HFNZ members with the aim of receiving marketable proofs and adding value to the future of New Zealand farming by increasing efficiency and production.

At least six bulls are selected to be sire-proven each year. The team is chosen following a rigorous selection process starting with the nomination of high-merit bull calves by HFNZ members, with eligible bulls having a DNA sampling taken for genotyping.

Once the team is selected the young bulls are housed at CRV and marketed through both CRV, in its Progeny Test herds, and Holstein Friesian NZ.

The Taylors' latest inclusions into the Genetic Leaders team - Muritai Bless Website S3F, Muritai Hustler Watchme-ET and Muritai Dubai Soul-ET-P - have a variety of outstanding traits.

Soul brings polled and red possibilities to the table, in conjunction with strong production genetics: Soul's great-granddam, Waipiri Oman Soul, holds the New Zealand record for top-producing three-year-old Holstein Friesian cow with 1,292kgMS.

Watchme combines three extremely strong cow families - Busy Brook's 'F', Maire's 'G' and Muritai's 'W' families - to create an outstanding pedigree animal, and Website's dam line has consitently achieve Production Worth (PW) in the 700s, reflecting their strong production.

"The Muritai 'W' family makes up around 70% of our herd," Wayne says.

Muritai Holsteins FBTW

Muritai Holsteins says good udders have become their point of difference.

"Good udders are their strongest trait, and one we have tried to maintain and focus on. We are not driven by indexing so udder traits have become our point of difference."

Wayne also says they are not afraid to use outcross genetics to achieve diversity.

"It has been a concern of mine that New Zealand bloodlines can become too closely related, so outcross genetics can again give us a point of difference."

HFNZ geneal manager Cherilyn Watson says purchasing semen from the Genetic Leaders team means accessing young, genomically-tested sires of pedigrees Holstein Friesian lineage at a cost-effective price.

Bull breeders themselves also benefit from the scheme, receiving genomic information for all bull calves selected. And with breeders who have bull calves accepted into the Genetic Leaders team required to sign into a contract with CRV, they are given the choice of a Royalty Option or Graduate Option as part of the agreement. HFNZ receives royalties under both options.

"There is a high success rate of sire-proving through this scheme," Cherilyn says.

"This year, Genetic Leaders' graduates Meander Shot Alibi-ET S3F and Rivendell Gforce Axel are being marketed by CRV once again, with newly graduated Rivendell MFU Scotch, who was part of the 2018 Genetic Leaders team, being marketed by CRV as a daughter-proven sire for the first time in 2022."
