Effect of age on leather and skin traits of slaughter ostriches

  • 2004
  • Issue: 2
  • Volume: 34
S.W.P. Cloete, S.J. van Schalkwyk, L.C. Hoffman and A. Meyer Page: 80 - 86

Little is known about the factors affecting leather and skin traits in ostriches. The effect of age on physical skin traits of slaughter ostriches was consequently investigated. Forty skins representing slaughter ages ranging from five to 14 months were selected…

  • Volume: 34
H. Lambrechts, D. Swart, S.W.P. Cloete, J.P.C. Greyling and S.J. van Schalkwyk Page: 87 - 96

The study provides information on the reproductive performance of ostriches maintained at different stocking rates and male:female (M:F) ratios under intensive commercial conditions in the Little Karoo, South Africa. Breeding ostriches are concentrated on relatively small areas and through trampling…

Genetic parameters for quail body weights using a random regression model

  • 2004
  • Issue: 2
  • Volume: 34
Y. Akbas, C. Takma and E. Yaylak Page: 104 - 109

A model including fixed and random linear regressions is described for analyzing body weights at different ages. In this study, (co)variance components, heritabilities for quail weekly weights and genetic correlations among these weights were estimated using a random regression model…

  • Issue: 3
  • Volume: 34
S.W.P. Cloete, J.J.E. Cloete, M.J. Herselman and L.C. Hoffman Page: 135 - 143

The production performance of ewes was assessed in a terminal crossbreeding experiment involving five Merino and Merino-type dam lines and two terminal crossbreeding sire breeds. Dam lines were SA Mutton Merino (SAMM), SAMM rams crossed to Merino ewes (SAMM cross),…
