Extract

Direct selection for fertility is difficult and yields little improvement because traditional parameters have low heritability and can only be measured in the mature female. A potential solution would be the use of an indirect selection criterion that is measurable in young bulls, is heritable and is genetically correlated to the fertility of the bull’s female progeny. The objective of this study was in investigate the genetic variation in free fatty acids (FFA), glucose, growth hormone (GH) and insulin concentrations in plasma from Danish male dairy calves following overnight fasting and the genetic covariation with fertility in their daughters.
