Autumn calving index sees Holstein dominance

The Autumn Calving Index (£ACI) ranking sees more dominance by the Holstein, and little change at the top since the last index run.

Westcoast Guarantee (£ACI 619) remains in number one position, ahead of Progenesis Unicorn (£ACI 600) up from third place. Hoanster Zanzibar (£ACI 595) moves one place down to third while Westcoast Yamaska (£ACI 578) moves up to fourth position.

The only newcomer in the £ACI top five is Stowey Magician (£575), who graduates as a milk quality and daughter fertility improver, also improving lameness and lifespans.
