The Irish Cattle Breeding Federation (ICBF) has revealed the most popular artificial insemination (AI) beef sires used on the suckler herd this year.
The results are based on AI servings recorded during the first six months of the year and are compiled from the insemination data collected from AI technicians linked to the ICBF database, through handheld systems.
Based on the data, there were 69,847 recorded serves, which is a slight decrease on the same period in 2022 when 72,103 serves had been recorded.
The table below shows the top 10 beef-breed bulls used on beef-sired cows, based on total AI handheld serves in the first six months of 2023:
The number one most-used beef bull so far this year is Lapp (CH4321), with 6,035 handheld serves recorded.
A National Cattle Breeding Center (NCBC) sire, Lapon was also the top bull on this list in 2022.
