Evaluation of in vivo techniques for the determination of apparent ileal amino acid digestibilities in feedstuffs for piglets

  • 2000
  • Issue: 1
  • Volume: 30
J. Viljoen, S.E. Coetzee, J.C. Fick, F.K. Siebrits and J.P. Hayes Page: 7 - 15

Three in vivo techniques were evaluated in terms of their suitability for determination of the apparent ileal amino acid digestibility (AID) of protein sources for piglets. The techniques were: ileo-rectal anastomosis (IRA), cannulation at the distal ileum and a slaughter…

A comparison of the yield, nutritional value and predicted production potential of different maize hybrids for silage production

  • 2000
  • Issue: 1
  • Volume: 30
R. Meeske, H.M. Basson, J.P. Pienaar and C.W. Cruywagen Page: 18 - 21

The yield, nutritional value and production potential of silage made from twenty one maize hybrids were compared. The digestibility of organic matter and predicted intake, mean retention time and milk production potential were found to differ between hybrids (p <…

The use of crude protein content to predict concentrations of lysine and methionine in grain harvested from selected cultivars o

  • 2000
  • Issue: 1
  • Volume: 30
D.A. Brandt, T.S. Brand and C.W. Cruywagen Page: 22 - 25

Correlations were determined between the crude protein (CP) and lysine or methionine concentrations of grain from wheat (cultivar: palmiet), barley (cultivar: clipper) and triticale (cultivar: usgen 19) grown in the Western Cape region of South Africa. Twenty samples of varying…

Growth, carcass and sensory characteristics of m. longissimus lumborum from wethers fed silage diets made from maize or various

  • 2000
  • Issue: 1
  • Volume: 30
M.J.C. Bosman, E.C. Webb, H.J. Cilliers and H.S. Steyn Page: 36 - 42

Growth, carcass characteristics and eating quality of meat from South African Mutton Merino wethers fed maize or different sorghum silage diets were studied. Forty newly weaned wethers (20 kg) were randomly allocated to 10 dietary treatments, viz. non-bird-resistant grain sorghum…

Phosphorus supplementation to natural pasture grazing for beef cows in the Western Highveld region of South Africa

  • 2000
  • Issue: 1
  • Volume: 30
C.H.M. de Brouwer, J.W. Cilliers, L.M. Vermaak, H.J. van der Merwe and P.C.N. Groenewald Page: 43 - 52

Simmentaler cows grazing Cymbopogon-Themeda veld in the western Highveld region of South Africa (1985/861989/90) received three levels of phosphorus (P) supplementation. Dicalcium phosphate content of the supplement was manipulated to give intakes of 8 (CS), 4 (HS) or 0 (ZS)…

The influence of proportion of Simmentaler breeding in a multibreed synthetic beef cattle population on preweaning growth traits

  • 2000
  • Issue: 2
  • Volume: 30
S.J. Schoeman, G.F. Jordaan and H. Skrypzeck Page: 98 - 109

Data from a multibreed composite beef cattle population managed under intensive irrigated grazing conditions were used to estimate direct additive heritabilities (h2a) and maternal heritabilities (h2m) for birth weight (BW) and weaning weight (WW) of the calf and cow efficiency…
