Estimates of variance components for postweaning feed intake and growth in Bonsmara bulls and evaluation of alternative measures of feed efficiency

  • 2013
  • Issue: 1
  • Volume: 43
M.D. MacNeil, M.M. Scholtz & A. Maiwashe Page: 18 - 24

Feed efficiency is of major economic importance in beef production. The objective of this work was to evaluate alternative measures of feed efficiency for use in genetic evaluation. To meet this objective, genetic parameters were estimated for the components of…

  • 2013
  • Issue: 1
  • Volume: 43
R. Danisman & R.M. Gous Page: 25 - 37

This is the second paper in a series that reports the allometric relationships between some of the physical parts and body protein weight of commercial broiler strains reared, sexes separate, on different dietary protein levels. In this trial, four commercial…

Oestrus induction using fluorogestone acetate sponges and equine chorionic gonadotrophin in Red Sokoto goats

  • 2013
  • Issue: 1
  • Volume: 43
B.O. Omontese, P.I. Rekwot, H.J. Makun, I.U. Ate, J.S. Rwuaan & M.U. Kawu Page: 69 - 73

The objective of this study was to evaluate the effect of a progestagen treatment (fluorogestone acetate sponge) alone or in combination with equine chorionic gonadotrophin (eCG) on oestrus response in Red Sokoto (RS) goats. One hundred RS does were treated…

Effective population size and inbreeding rate of indigenous Nguni cattle under in situ conservation in the low-input communal production system (Short communication)

  • 2013
  • Issue: 2
  • Volume: 43
O. Tada, V. Muchenje & K. Dzama Page: 137 - 142

Nineteen rural Nguni cattle enterprises managed at communal and small-scale level were used in a study to determine population genetic parameters, level of Nguni genetic contribution, and risk status of community-based animal genetic resources. Chi-square tests were performed to ascertain…

Crossbreeding to increase beef production: additive and non-additive effects on weight traits

  • 2013
  • Issue: 2
  • Volume: 43
A. Theunissen, M.M. Scholtz, F.W.C. Neser & M.D. MacNeil Page: 143 - 152

Using breed differences effectively facilitates high productivity and profitability. Thus, the objective of the study was to estimate direct and maternal additive and heterosis effects for growth traits (birth weight, weaning weight, 19-month weight of heifers and cow weight) from…

Germination as a processing technique for soybeans in small-scale farming

  • 2013
  • Issue: 2
  • Volume: 43
N.C. Kayembe & C. Jansen van Rensburg Page: 167 - 173

Heat processing is an effective way of reducing antinutritional factors (ANFs) in legumes, but requires expensive facilities and equipment. Accurate control of temperature is critical to avoid under- or overheating. Therefore, heat treatment of soybeans is not a viable option…
