Amino acid availability in poultry - in vitro and in vivo measurements
Published 1999-01-01Methodology 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 ...Open AccessArticle -
An assessment by in vivo methods of grain quality for ruminants
Published 1999-01-01For 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 ...Open AccessArticle -
Associative effects between forages and grains: consequences for feed utilisation
Published 1999-01-01Intake 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 ...Open AccessArticle -
Australian Cereal Rust Control Program - Continued monitoring of cereal rust pathogens in Australia
Published 2023-06-26The GRDC funded survey project monitored national rust pathotype incidence and distribution (changes) through samples received and regular crop inspections for wheat, barley and oats in seven agroecological zones in ...Open AccessOther -
Australian Cereal Rust Control Program - Wheat and barley breeding support
Published 2023-06-28This collection includes results of rust screening of advanced breeding lines of bread wheat, barley, and oats with identified rust pathotypes in the greenhouse and in field between 2018 and 2022. Greenhouse rust testing ...Open AccessOther -
Cereal structure and composition
Published 1999-01-01Cereals 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 ...Open AccessArticle -
Chemical and physical characteristics of grain related to variability in energy and amino acid availability in pigs: a review
Published 1999-01-01To optimise pig production, there is a need to define the variation in the available energy and amino acid content of feed grains and to understand those factors that influence nutritive value. Differences of up to 3.7 ...Open AccessArticle -
Chemical and physical characteristics of grains related to variability in energy and amino acid availability in poultry
Published 1999-01-01Grains 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 ...Open AccessArticle -
Chemical and physical characteristics of grains related to variability in energy and amino acid availability in ruminants: a review
Published 1999-01-01This 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 ...Open AccessArticle -
Comparison of methods used to predict the in vivo digestibility of feeds in ruminants
Published 1999-01-01Digestibility 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 ...Open AccessArticle -

The energy value of cereal grains, particularly wheat and sorghum, for poultry
Published 2005-01-01Results from the Premium Grains for Livestock Program were analysed to identify variation in the energy value for laying hens and broiler chickens of cereal grains including wheat, barley, oats, triticale, sorghum and rice. ...Open AccessConference paper -
Evaluation of various NIR instruments for estimating grain quality for livestock
Published 2005-01-01A large national research project in Australia over the past seven years has focused on improving the quality of grains for feeding to livestock. A major expectation of the grain and livestock industries from this project ...Open AccessConference paper -
Extrustion and expansion of cereal grains promotes variable energy yields in pigs, broiler chickens and laying hens
Published 2005-01-01Maximising digestible energy (DE) yield from cereals is fundamental to optimising efficiency in pig and poultry production systems. Given the potential interaction between grain structure and composition and DE (or AME) ...Open AccessConference paper -
Factors influencing the energy values of Australian cereal grains fed to broilers
Published 2001-01-01The apparent metabolisable energy (AME) values for selected samples of wheat, barley, triticale, oats and sorghum grown in Australia were determined in energy balance experiments with young broilers of both sexes. Ileal ...Open AccessConference paper -
Feed uses for barley
Published 2005-01-01Cereal grains with their high starch content are fed to livestock predominantly as a source of energy for rapid growth or high milk yield and also for subsistence in times of poor pasture availability. Results from the ...Open AccessConference paper -
Genotype and environment effects on feed grain quality
Published 1999-01-01The extent of genotype and location effects on chemical composition and nutritive value of grains fed to animals was surveyed. The review covered the winter cereals (wheat, barley, oats, and triticale), the summer cereals ...Open AccessArticle -
