Genetic studies on the South African Mutton Merino: growth traits

  • 2000
  • Issue: 3
  • Volume: 30
F.W.C. Neser, G.J. Erasmus and J.B. van Wyk Page: 172 - 177

Genetic parameters were estimated for 36-, 42-, 50-, 100- and 150-day weight in the South African Mutton Merino breed. The direct heritability estimates obtained were 0.270, 0.366, 0.278, 0.185 and 0.115 respectively. The maternal heritability estimates for the respective weights…

Genetic trends in a South African Mutton Merino nucleus breeding scheme

  • 1999
  • Issue: 1
  • Volume: 29
H.Q. Gray, F.W.C. Neser, G.J. Erasmus and J.B. van Wyk Page: 48 - 53

Genetic parameters and trends were estimated for 2296 lambs from a SA Mutton Merino nucleus breeding scheme using multiple trait mixed model procedures. Direct heritability estimates obtained for the traits were 0.32 for weaning weight, 0.03 for post-weaning average daily…
