The effect of rumen inert fat supplementation and protein degradability in starter and finishing diets on veal calf performance

  • 2003
  • Issue: 4
  • Volume: 33
C.W. Cruywagen, E.L. Lategan and L.C. Hoffman Page: 257 - 265

Thirty six Holstein bull calves were divided into six groups to determine the effect of protein degradability and rumen inert fat supplementation in starter and finishing diets on nutrient digestibility and veal production. Calves received low (LD) or high (HD)…

Transcervical embryo recovery in Saanen goats

  • 2003
  • Issue: 2
  • Volume: 33
J.B. Lima-Verde, E.S. Lopes Junior, D.I.A. Teixeira, N.R.O. Paula, A.A. Medeiros, D. Rondina and V.J.F. Freitas Page: 127 - 131

In order to study the embryo recovery rate using the transcervical technique in Saanen goats raised in the tropics, 20 donors were submitted to an oestrus synchronisation treatment using intravaginal progestagen sponges for 11 days. On the ninth day of…

Genetic parameters and trends for birth weight, birth coat score and weaning weight in Merino lines divergently selected for ewe

  • 2003
  • Issue: 4
  • Volume: 33
S.W.P. Cloete, J.J. Olivier, J.B. van Wyk, G.J. Erasmus and S.J. Schoeman Page: 248 - 256

Data were recorded for birth weight, birth coat score and weaning weight of between 2018 and 4235 Merino lambs born over a 17-year interval from 1986 to 2002. The resource population was divergently selected from the same base population since…

Evaluation of the growth parameters of six commercial crossbred pig genotypes 2. Under ideal temperature conditions in chambers

  • 2003
  • Issue: 1
  • Volume: 33
N. S. Ferguson and S.T. Kyriazis Page: 21 - 26

To test whether animals grown under ideal temperature conditions would have different growth parameters to animals grown in more conventional housing, sixty Large White x Landrace male pigs from three genotypes were housed in six temperature-controlled chambers. The results were…

Revised models and genetic parameter estimates for production and reproduction traits in the Elsenburg Dormer sheep stud

  • 2003
  • Issue: 4
  • Volume: 33
J.B. van Wyk, M.D. Fair and S.W.P. Cloete Page: 213 - 222

Genetic parameters for production and reproduction traits in the Elsenburg Dormer sheep stud were estimated using records of 11743 lambs born between 1943 and 2002. An animal model with direct and maternal additive, maternal permanent and temporary environmental effects was…
