Five of the top ten AI sires on the ICBF Replacement Index Active Bull List are graduates of the Gene Ireland Programme. This is after the latest evaluation publication on Tue 27th July. These sires were identified by breed committees over the last 8 years and were tested in commercial suckler herds. The five Gene Ireland sires have an average Replacement Index of €211 at 72% reliability and have sired a total of 14,500 progeny. This is testament to the importance of a strong domestic breeding programme with continued collaboration between ICBF, breed societies, all AI companies and the wider industry.
