More Genomic Breeding Values on the Spanish scale
What is ICO and gICO?
The ICO for “Production and Functionality” is the total merit index that is used in Spain for ranking bulls according to the Spanish breeding goal. As soon as genomic information is available, gICO can be computed.
What are the benefits of using gICO?
gICO is a breeding goal that aims for the most profitable animals in the future economic circumstances. Spain is producing annually 6 Million of tons of milk and consumes 9 Million of tons of Milk. Therefor gICO is first focused on production and type. Nevertheless, the definition of gICO has been changed in June 2015 to give more and more importance to the functional traits (fertility, longevity, udder health).
How to understand gICO?
- Official national breeding values for bulls on the Spanish scale have an average of 1614 and a standard deviation of 1000.
- 99% of all bulls with official national proof at CONAFE have breeding values below +3178.
- This means that bulls with a proof higher or equal to +3178 represent the top 1% of all bulls with official national breeding values.
- Mean and percentiles are shown at the following link: http://184.108.40.206/IndicesGen/Percentil_Toros.aspx
Who is responsible for estimation and publication of breeding values?
CONAFE is responsible for the computation of genomic breeding values, 10 times a year, for traits included into gICO as well as calving and workability traits. CONAFE is also responsible for the offical publication of national and international breeding values.
Where do you search for the gICO of a specific sire?
gICO and all other breeding values calculated by CONAFE can be found on CONAFE Bull Search (official website).
