    • Strategies for the assessment of Livestock feed ingredient quality 

      van Barneveld, R. J (University of New England, 1999)
      Potential exists to improve current strategies and methods employed to assess livestock feed ingredient quality. Of paramount importance to any assessment procedure is representative sampling of the test ingredient. ...

      van Barneveld, Samantha (CSIRO Publishing, PO Box 1139, Collingwood, Vic. 3066, 1999)
      This paper reviews the carbohydrate, protein, lipid, anti-nutritional, and physical characteristics of grains that determine the variability in their nutritional quality for ruminant animals. The amount, rate, and extent ...
    • Increasing the utilisation of grain when fed whole to ruminants 

      Kaiser, A. G (CSIRO Publishing, PO Box 1139, Collingwood, Vic. 3066, 1999)
      Feeding grain whole to cattle generally results in a lower digestibility than that obtained with processed grain. If this problem could be overcome, feeding with whole grain would reduce processing costs, and the slower ...
    • Cereal structure and composition 

      Evers, A. D; Blakeney, A. B; O'Brien, L (CSIRO Publishing, 1999)
      Cereals are cultivated grasses that are grown throughout the world. As well as providing food for man, they, or fractions derived from processing them, make an important contribution to the diets of farm stock. Cereal ...
    • Amino acid availability in poultry - in vitro and in vivo measurements 

      Ravindran, V; Bryden, W. L (CSIRO Publishing, PO Box 1139, Collingwood, Vic. 3066, 1999)
      Methodology to evaluate the protein quality or amino acid availability in feed ingredients for poultry using in vitro (enzymic, chemical, or microbiological assays), indirect in vivo (plasma amino acid assays), or direct ...
    • Processing cereal grains for animal feeding 

      Rowe, J. B; Choct, M; Pethick, D. W (CSIRO Publishing, PO Box 1139, Collingwood, Vic. 3066, 1999)
      This review concentrates on factors influencing the nutritive value of cereal grains for animals and strategies, in particular processing and storage, which may be used to optimise fermentation and digestion. The main focus ...
    • In vivo and in vitro techniques for the assessment of the energy content of feed grains for poultry: a review 

      Farrell, D. J (CSIRO Publishing, PO Box 1139, Collingwood, Vic. 3066, 1999)
      The focus of this paper is on the energy evaluation of foodstuffs, particularly of food grains for poultry. Apparent metabolisable energy (AME) is currently the preferred feeding system for poultry but net energy systems ...
    • An assessment by in vivo methods of grain quality for ruminants 

      Hogan, J. P; Flinn, P. C (CSIRO Publishing, PO Box 1139, Collingwood, Vic. 3066, 1999)
      For the purpose of this review, grain quality refers to the efficiency with which a grain supports growth in cattle fed diets which contain grain as a major component. Grains are fed as concentrated sources of energy. Their ...
    • Comparison of methods used to predict the in vivo digestibility of feeds in ruminants 

      Kitessa, S; Flinn, P. C; Irish, G. G (CSIRO Publishing, PO Box 1139, Collingwood, Vic. 3066, 1999)
      Digestibility is a very useful index of the energy content of ruminant feeds, but cheaper and quicker laboratory methods are required as an alternative to the ultimate measure of in vivo digestibility using animals. These ...
    • Chemical and physical characteristics of grains related to variability in energy and amino acid availability in poultry 

      Hughes, R. J; Choct, M (CSIRO Publishing, PO Box 1139, Collingwood, Vic 3066, 1999)
      Grains such as wheat and barley, combined with legumes and oilseed meals, provide not only the bulk of essential nutrients for commercial poultry production and reproduction, but are also the prime source of anti-nutritive ...
    • Associative effects between forages and grains: consequences for feed utilisation 

      Dixon, R. M; Stockdale, C. R (CSIRO Publishing, PO Box 1139, Collingwood, Vic. 3066, 1999)
      Intake of metabolisable energy (ME) when forages and grains are fed together to ruminants may, due to digestive and metabolic interactions, be lower or higher than expected from feeding these components separately. These ...
