  • Issue: 3
  • Volume: 47
A. E. Untea, I. Varzaru, T. D. Panaite, M. Habeanu, M. Ropota, M. Olteanu & G. M. Cornescu Page: 332 - 341

The aim of the study was to evaluate the effects of chromium picolinate (CrPic) on growth performance, nutrient digestibility, and protein and lipid quality of five anatomical parts in growing pigs. The 30-day study was conducted on eight castrated Topigs…

Nutrient content of sorghum beer strainings

  • 1987
  • Issue: 4
  • Volume: 17
I.V. van Heerden Page: 171 - 175

A study was carried out to determine what contribution the consumption of sorghum beer strainings (SBS) could make towards animal nutrition. Sorghum beer strainings were analysed for starch, protein, fat, crude fibre, ash, minerals and phytate content on a dry…

The use of pigs both intact and with ileo-rectal anastomosis to estimate the apparent and true digestibility of amino acids in u

  • 1990
  • Issue: 4
  • Volume: 20
T.S. Brand, H.A. Badenhorst, F.K. Siebris and J.P. Hayes Page: 223 - 228

This experiment was conducted to determine apparent and true amino acid digestibilities of untreated (BPS), heat-treated (HBPS) and thermal-ammoniated (NH3BPS) high-tannin sorghum with pigs both intact and with an ileo-rectal anastomosis (IRA). The mean endogenous protein secretion for the surgically…

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…

Amino acid metabolism and whole-body protein turnover in lambs fed roughage-based diets: 1. Lysine and leucine metabolism

  • 1992
  • Issue: 6
  • Volume: 22
P.B. Cronjé, J.V. Nolan and R. A. Leng Page: 194 - 200

The experiments reported in this series were designed to investigate the metabolism of lysine, leucine and methionine in lambs fed roughage diets supplemented with various levels of protein. and to compare these amino acids as tracers of whole-body protein metabolism…

Effect of fortifying amaranth diets with amino acids, casein and ethylene diamine tetraacetate on broiler performance, amino aci

  • 2002
  • Issue: 2
  • Volume: 32
L.W. Kabuage, P.N. Mbugua, B.N. Mitaru, T.A. Ngatia and K. Schafer Page: 144 - 153

Two broiler feeding trials (1-31 days of age) were carried out to determine the effect of fortifying grain amaranth diets with lysine, methionine, casein and ethylene diamine tetraacetate (EDTA) on performance, amino acid availability, plasma amino acids, nitrogen and mineral…

Amino acid metabolism and whole-body protein turnover in lambs fed roughage-based diets: 2. Methionine metabolism and a compari

  • 1992
  • Issue: 6
  • Volume: 22
P.B. Cronjé, J. V. Nolan and R.A. Leng Page: 201 - 206

The effect of protein supplementation of a wheat straw diet on the metabolism of lysine, leucine, methionine and urea,  and on whole-body protein turnover rate was investigated in lambs. The metabolism of lysine and leucine is reported elsewhere (Cronje et…

Plasma free amino acid profiles of Boer goat bucks as influenced by two feeding regimens

  • 2006
  • Issue: 5
  • Volume: 36
A.M. Almeida, L.M.J. Schwalbach, H.O. de Waal, J.P.C. Greyling and L.A. Cardoso Page: 14 - 17

The aim of the study was to monitor the physiological changes in plasma free amino acid profiles in Boer goats under nutritional restriction. Fifteen Boer goat bucks were allocated to two experimental groups: CG (control), fed Themeda trianda hay, supplemented…

Effects of infused methionine, lysine and rumen-protected methionine derivatives on nitrogen retention and wool growth of Merino

  • 1995
  • Issue: 4
  • Volume: 25
J. Coetzee, P.J. de Wet and W.J. Burger Page: 87 - 94

Nitrogen (N) retention and wool growth rate (WGR) responses to various amino acids and derivatives as well as protein sources were determined with six ruminally and six abomasally fistulated Merino wethers in two balanced cross-over design experiments. The six treatments…

Effect of cyadox on growth and nutrient digestibility in weanling pigs

  • 2005
  • Issue: 2
  • Volume: 35
Y. Wang, Z. Yuan, H. Zhu, M. Ding and S. Fan Page: 117 - 125

The effect of cyadox on growth and apparent digestibility of nutrients in weanling pigs was investigated. Cyadox (2-formylquinoxaline-N1,N4-dioxide cyanocetylhydrazone) is a derivative of quinoxaline-1, 4-dioxide, a growth promoting antimicrobial agent that is used in pig production. Seventy-five crossbred weanling barrows…
