NEWBULLS:BECIRCUMSPECT…

FOUR new bulls have entered the May Holstein Top 10 PLI ranking, but all should be used cautiously.

Cogent is pleased to have topped the list with Fatal-son Courier, but warn that reliability is still low with 22 daughters in 20 herds at present. The bull does, however, offer £101 PLI with 1088kg of milk and 36.4kg of protein. He is also fifth on Holstein UKs TOP ranking.

Genus also urge caution over fourth place bull Vision-gen Ozzie. Although he has a PLI of £96 and type merit of 1.9 and leads the TOP ranking, Genuss James Simpson is cautious in praising Ozzie until he has more daughters in his proof.

"Currently, Ozzie has 53 daughters in his production proof giving a reliability of 69%. But he is looking well balanced on milk production and type merit, with a somatic cell count score of -12."

In fifth place is a new Dutch-bred sire, Newhouse Spiceman, offering good value at £15/straw, says Avoncrofts David Mathews. "He offers a huge amount of fat and protein at 30.9kg and 38kg, respectively, and he is plus on percentages."

However, MDC Evaluations warn that the Zandenburger Royal son, Spiceman is a carrier of complex vertebral malformation (CVM).

The fourth new sire, Cogent Merrick, is also by Fatal, and although he has a few more daughters, with 51 in 31 herds, reliability is just 81%. &#42
