Shaver Composites and Heterosis
by shaverbeef on Saturday 05 November 2005
Hybrid vigour is expressed in economically important traits such as calving ease, growth rate, carcass quality, yield and possibly short gestation calves . It also overcomes antagonistic traits like lean carcass vs. marbling. Some of these traits have a low heritability and are difficult to breed for in purebreds. More heterosis comes from more breeds in a composite; Shaver Composites are made up of 9 breeds.
