I. IntroductionGrains are the major energy sources in broiler diets. However, they also supply about 40% of the total dietary protein and contribute significantly to the provision of some indispensable amino acids (IAA; Szczurek et al., 2020). Despite the low protein content in maize, owing to its higher inclusion levels (50-70%) it may contribute approximately up to one third of the protein requi ...

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 ...
