• The dam of Genosource Captain, the number one young genomic sire
Genosource Captain has pushed to the top position in the Profitable Lifetime Index (£PLI), just as he has done for every one of the previous three runs of genetic evaluations in the new Holstein sire choices, published this week by AHDB Dairy.
This bull provides a resounding endorsement of the genomic testing system, in particular through his sire, Hurtgenlea Richard Charl, who graduates on to the proven sire list as the new number one bull with milking daughters.
Captain himself rises on PLI to £963, transmitting high milk volume (Predicted Transmitting Ability for milk is 1095kg), good milk solids (+0.14% fat and +0.04% protein) and favourable maintenance costs at -16. He also scores -3 on the newly introduced Gestation Length Index (GL), indicating his calves will, on average, have a shorter gestation than the national average by three days.
