An investigation into possible genotype x environment interactions for weaning weight in South African Mutton Merino sheep

  • 1998
  • Issue: 3
  • Volume: 28
F.W.C. Neser, G.J. Erasmus, J.B. van Wyk, C.S. van Deventer Page: 179 -

Weaning weight records available for the South African Mutton Merino breed wereutilised to investigate the possibility of a genotype by environment interaction in the breed. A direct heritability estimate of 0.308 ± 0.022 was obtained. Including flock-year-season x sire interaction…
