me value and nutrient composition of cereal grainsthe typical metabolisable energy (me) and nutrient composition of different cereal grains is shown in table 1.

wheat 13.0 3153 0.05 0.20 0.5
sorghum 9.0 3263 0.02 0.15 0.3

the quality of cereal grains will also depend on seasonal and storage conditions. poor growing or storage conditions can lead to grains with a lower than expected energy content or contamination with mycotoxins or toxin producing organisms such as fungi and ergots. genetic and environmental factors also affect not only the content of nutrients in grains but also the nutritive value, which takes into account the digestibility of nutrients contained in an ingredient in the target animal.
in addition to the cereals themselves, their by products, such as wheat bran, rice bran and ddgs, are used widely in poultry feed. cereal by products are typically high in fibre, or non starch polysaccharides (nsp), which are poorly utilised in poultry and are low in me.
protein meals
protein is provided from both vegetable and animal sources, such as oilseed meals, legumes and abattoir and fish processing by products.
vegetable protein sources
vegetable protein sources usually come as meal or cake, the by product of oilseed crops. the main oilseed crops include soybean, rapeseed/canola, sunflower, palm kernel, copra, linseed peanut and sesame seed. after the oil is extracted, the remaining residue is used as feed ingredient. oilseed meals make up 20 25% of a poultry diet. inclusion levels do vary among formulations for different species and for the same species in different regions.
