Generation length


Breeding values help you select the animals this year with better genes than the previous year. The youngest animals should, on average, have better genes than their parents. These animals are the beneficiary of the hard work in previous years.

These younger animals are the future of your breeding program. Use them. This gets the best genetics into your flock faster and speeds up the rate of genetic gain.

The average age of a flock’s breeding animals is its generation interval. Decreasing the generation interval increases genetic gain. ASBVs take into account the age of an animal. Investigate opportunities to join ram lambs or ewe lambs where you can provide ample nutrition.
