Nice study and findings. It would be interesting to see if the inorganic P source, MCP here, could be completely removed by higher dose of phytase, especially during the finisher phase.

I. IntroductionPoultry diets are currently formulated based on total calcium (Ca) and available phosphorus, with a ratio of 2:1 being maintained between them. For a number of reasons, there is increasing interest in shifting the formulations based on digestible Ca and digestible P. To enable this move, information is required of the requirements of digestible Ca and digestible P. A recent study at ...

Evaluation of true ileal digestible energy, as a potential energy system for application in broiler feed formulations, requires accurate estimation of the ileal endogenous energy losses (IEEL). The IEEL estimates can be influenced by several factors including bird age and dietary cellulose levels (Khalil et al., 2020). Two experiments were conducted to investigate the influence of age and dietary ...

1. IntroductionHumphry Davy, a British chemist, was the first to isolate and investigate the chemistry of calcium (Ca) and to recognise it as an essential component of bone in 1808. Ever since, it has been the subject of a voluminous amount of research in both human and animal nutrition. Today, the biological significance and economic importance of Ca in animals are intuitive. Calcium is the most ...

I. INTRODUCTION Cereal grains such as wheat, sorghum, barley and maize are commonly used in poultry diets as the main source of energy. Knowledge on the metabolisable energy content of cereal grains is critical for their efficient use and precise poultry feed formulation. Despite several limitations (Mateos et al., 2019; Wu et al., 2020), the AME has been the globally accepted system for describin ...

Soybean meal (SBM) and canola meal (CM) are two plant-based protein sources which contain reasonable amounts (2.9 and 6.8 g/kg, respectively) of calcium (Ca). Currently, no published values are available for the Ca digestibility in SBM and limited studies (Anwar et al., 2018; Moss et al., 2018) are available for the Ca digestibility in CM. Microbial phytases are now routinely added in poultry diet ...

INTRODUCTIONLeast cost feed formulation relies on the assumption of additivity of digestible nutrients from the contributing ingredients. It is generally accepted that assessment of the nutritional value of individual raw materials underestimates their eventual contribution in a complex diet because of the often-substantial influence of endogenous loss. The premise is that a proportion of nutrient ...

I. INTRODUCTION With the recognition that pelleting can enhance the feeding value of barley in poultry diets, mostly through the break-down of cell wall matrix resulting a greater accessibility of encapsulated nutrients to digestive enzymes (Abdollahi and Ravindran, 2019), barley has been successfully used in pelleted broiler diets (Perera et al., 2019b; Perera et al., 2020). While the optimum inc ...
