Suckler herd AI trends
An analysis undertaken by the ICBF indicates that for the past two years in the suckler herd, overall AI usage has decreased by 6% from 2017 to 2018.
According to the ICBF, this correlates with the reduction of suckler cow numbers that has also taken place during the same period.
From the analysis, the busiest month for AI usage in the suckler herd was June for both years and the total number of beef AI bulls used increased in 2018 from the previous year. So far in 2019, both these trends have remained similar to both 2017 and 2018.
How is 2019 shaping up?
The figures listed below do not take into account DIY serves, so actual usage will be higher in reality.
Firstly, if we look at the most popular beef AI sire used on the suckler herd for the first six months of the year, we can see that Limousin bull – Castleview Gazelle (ZAG) – is the most used sire up to June 30, 2019, with 8,701 AI handheld serves.
Charolais bull Fiston (FSZ) comes in at second place on the list with 7,796 AI handheld serves recorded.
Third on the list is Moondharrig Knell (LM 4217) – a Limousin sire – with 4,626 AI handheld serves recorded.
In addition, Charolais and Limousin sires take nine places in the top 10 list, with Simmental bull, Lisnacrann Fifty Cent (SI 2469) – that has 1,681 AI handheld serves – coming in at eighth position.
Secondly, the most popular AI beef sire used on the dairy herd up until June 30, 2019, was Solpoll 1 Kentucky Kid P HYF (HE 2043), with a total of 10,373 handheld serves; this sire has a calving difficulty of 3.2%.
Manitou De Belle Eau (DBZ) – a Belgian Blue bull – is in second position with 9,538 AI handheld serves; DBZ has a calving difficulty of 7.6%.
Angus bull – Cornamuckla Lord Hardy K222 (KYA) – has a total of 8,810 handheld serves and comes in third position. All the AI beef sires – used on the dairy herd – in the top 10 are either Hereford, Belgian Blue or Angus.
