Broiler breeders utilise body lipid as an energy source

  • 2012
  • Issue: 4
  • Volume: 42
M.K. Nonis & R.M. Gous Page: 369 - 378

The study was conducted to determine the extent to which broiler breeder hens could make use of excess body lipid reserves as a means of maintaining laying performance. The experiment was divided into two phases. In the first phase, the…

Dietary Rhus coriaria L. powder reduces the blood cholesterol, VLDL-c and glucose, but increases abdominal fat in broilers

  • 2012
  • Issue: 4
  • Volume: 42
M. Golzadeh, P. Farhoomand & M. Daneshyar Page: 398 - 405

In an experiment, 200 one-day-old broiler chickens (Ross 308) were used to investigate the effects of sumac fruit (Rhus coriaria L.) powder (SFP) on performance, plasma concentrations of total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL-c), low density lipoprotein…

Variety effect on composition, kinetics of fermentation and in vitro digestibility of oat (Avena sativa L.) straw and its neutral detergent fibre

  • 2012
  • Issue: 4
  • Volume: 42
F. Kafilzadeh, N. Heidary & S. Bahraminejad Page: 406 - 415

Yield, chemical composition, in vitro digestibility and kinetics of fermentation of straw from 18 varieties of oats (Avena sativa L.) were studied. All the straw varieties were grown in three replicates under the same agronomic conditions. Significance differences were observed…

Fatty acid composition and oxidative stability of lambs’ meat as affected by a bioflavonoid antioxidant and fat sources

  • 2012
  • Issue: 5
  • Volume: 42
K.E. Booyens, O.B. Einkamerer, A. Hugo, H.J. van der Merwe, S.C. Slippers & M.D. Fair Page: 483 - 487

A study was conducted to investigate the effects of a synthetic or natural antioxidant and fat saturation, in a standard feedlot diet, on fatty acid composition and oxidative stability of lamb. The four dietary treatments consisted of the same basal…
