Genetic correlations between female fertility and production traits in South African Holstein cattle

  • 2007
  • Issue: 3
  • Volume: 37
M.L. Makgahlela, C.B. Banga, D. Norris, K. Dzama and J.W. N'gambi Page: 180 - 188

Female fertility is increasingly gaining importance in national dairy cattle breeding objectives worldwide. In South Africa, there is no routine prediction of breeding values for reproductive performance in dairy cattle and selection is mainly focused on production traits. The objective…
