Charollais Updates Index For Fatter, Quicker Growing Progeny

18 February 2015

UK – A new breeding index will mean slightly fatter Charollais sheep that will be well-muscled, faster-growing and higher in commercial value.

Signet breeding services has announced the new index for those looking to improve growth and finishing rates of performance recorded Charollaise-sired lambs.

Retaining the changes made ten years ago to penalise sheep with very low fat depth Estimated Breeding Values (EBVs), the index will now “reduce the emphasis currently applied to sheep with genetically lower levels of fat within the overall carcase”.

Samuel Boon, EBLEX Breeding Specialist, said: “These changes will provide lambs with slightly higher levels of finish on lower input systems – with slightly faster growth rates. Ultimately these changes are a win-win for the breed.

“However, at a national level nearly 27 per cent of lambs are still fatter (3H or more) than market requirements, so producers are urged to select lambs for slaughter carefully and use the right genetics to optimise market returns.”

Commenting on progression in genomics, Jonathan Barber, Charollais Sires Chairman said: “The use of performance records, ultrasound scanning and computed tomography has done a tremendous job identifying elite terminal sires.”

“These changes are a natural progression, which ensures high-index Charollais sires meet the needs of the industry.”
