To satisfy an inquiry from a Nebraskan ShortCattleman, who was seeking to improve the marbling genes in his Shorthorn cattle, our bull, Ardrossan Jamberoo, has just undergone a Repro test on his semen.
Jamberoo at 18 months
This test examines the fresh semen to discover whether the semen contains the Heparin Binding Protein.
Scientific data has proven that this protein, only possessed by 75% of bulls of all breeds, is an indication of fertility.
Profitability to be gained in the female herd are:-
* Cows sired by bulls with the Heparin Binding Protein are more fertile.
* These cows have an increased first service conception rate.
* They have increased weaning weights.
* Fewer replacements are needed to maintain constant herd size.
