The Replacement Index is part of ICBF’s Euro-Star Index system. It is a tool used by suckler farmers to breed/select more profitable replacement females. It comprises cost of production traits such as calving difficulty and cow liveweight as well as output traits such as milk and carcass weight.
When used properly, the selection of animals using the Replacement Index will result in more efficient suckler cows with more milk and fertility whilst also producing superior offspring.
The data hereunder shows that the percentage trend has been relatively stable since 2013. On average, 23% were dairy x beef and 77% of suckler cows were beef x beef.
Current and historic information on dairy cross animals in the suckler herd is tabulated below.
