Usage Advice
This is the overall single ļ¬gure proļ¬t index that each bull has. A Bull with a Replacement Index of ā¬200 is expected to sire daughters that are ā¬200 more proļ¬table than the average Irish suckler cow.
This is the expected percentage of difļ¬cult calvings that a bull will bring.
If a bullās āreliability %ā for the āReplacement Indexā is under 85% then it is advised that he is used in a āTeamā, alongside as many other AI Sires as possible. A team of 5 bulls, if possible, is recommended. This is because the maternal abilities of daughters of such bulls is not yet fully known and so it would be risky to just use semen from one of these bulls. āProvenā identiļ¬es a bull with a reliability % over 85% which could be used on his own.
A bullās full index can be seen on the ICBFās online bull search at www.icbf.com.
