INTRODUCTIONCereal grains such as wheat, sorghum, barley, and corn are commonly used in poultry diets as major sources of energy. Knowledge of the ME content of cereal grains is critical for their efficient and sustainable use and precise poultry feed formulation. Despite several limitations (Mateos et al., 2019; Wu et al., 2020), the AME is the globally accepted system for describing the availabl ...

1. IntroductionAvailable energy in feed or feed ingredients for poultry can be measured by different systems, with the apparent metabolizable energy (AME) [1], despite its limitations [2,3], being the commonly accepted and extensively used system.Three methods, namely, direct, substitution (or difference), and regression, have been used to determine the AME of ingredients for poultry. In each meth ...

During the process of digestion and absorption of ingested feed in poultry, significant losses of endogenous amino acids (EAA) occur from various digestive secretions, mucoproteins and the epithelial cells lining the gastrointestinal tract (GIT). Several factors such as the development of GIT and changes in dry matter intake (DMI) with advancing age, type of bird, method of euthanasia and ileal di ...

I. INTRODUCTIONKnowledge on the digestibility of amino acids (AA) in raw materials is crucial for precise feed formulation, and for more efficient and sustainable use of feed resources. The accuracy of excreta-based digestibility measurements for determining N and AA digestibility may be questionable, due to the variable effects of the caecal microflora on dietary protein utilisation and the contr ...

Fats and oils are widely used in poultry diets as a source of energy and to increase palatability. Increasing dietary fat level has been reported to improve the apparent ileal digestibility of amino acids (Cowieson and Ravindran, 2008). These improvements may be related, in part, to reduced endogenous amino acid (EAA) losses, but the influence of dietary fat on EAA losses has not been studied in c ...

I. INTRODUCTIONCereal grains are ground prior to feed mixing to reduce the particle size with the aim of modifying their physical characteristics. This facilitates handling, mixing and further processing (extrusion and pelleting) and increases the exposure of nutrients in the endosperm to digestive enzymes (Amerah et al., 2011). Available recommendations regarding optimum particle size are contrad ...

I. INTRODUCTIONEstimating the available energy of feed ingredients is fundamental to formulating a well-balanced diet and lower the production cost. Measurement of apparent metabolisable energy (AME) is the accepted standard procedure for evaluating the available energy value of ingredients for poultry, as it is simple and straightforward and considers most of the energy losses after digestion and ...

The influence of inclusion level of barley in wheat-based diets and supplementation of a multicomponent non-starch polysaccharide (NSP) degrading enzyme (Ronozyme® Multigrain) on growth performance and nutrient utilisation in broiler starter (d 0 to d 21) was evaluated. The activities of endo-1,4-β-glucanase, endo-1,3(4)-β-glucanase and endo-1,4-β-xylanase in enzyme were 800 BGU ...

1. IntroductionSimilar to mammals, the liver in birds is involved in an array of metabolic and homeostatic functions and considered as a biochemical factory responsible for most of the synthesis, metabolism, excretion, and detoxification processes. It plays an important role in digestion and metabolism, regulating the production, storage, and release of lipids, carbohydrates and proteins [1]. The ...
