INTRODUCTIONIn the United States and most parts the world, the biggest portion of poultry diets is comprised of carbohydrates, with corn being the main cereal grain used in the feed industry (Moran, 1982; Ai and Jane, 2016; Agristats, 2018; IGC, 2018). Corn is dried on the field or usually dried either by constant flow or batch drying after harvesting, so it could be included in poultry feeds. It ...

Soybean meal (SBM) and canola meal (CM) are the main contributors to the protein fraction in poultry diets worldwide. However, these quality vegetable protein meals contain low molecular weight sugars (raffinose and stachyose) and cell wall pectic non-starch polysaccharides (NSPs), cellulose and hemicellulose (e.g. xyloglucans and mannans) which can be problematic. These NSPs are notorious for the ...

Dietary protease supplementation has been observed to improve broiler growth performance and amino acid digestibility (Angel et al., 2011; Fru-Nji et al., 2011). Improvements in broiler energy utilisation have also been observed with supplemental protease (Sorbara, 2009; Freitas et al., 2011). These positive extra-proteinaceous effects may be influenced by age and diet type. In addition, these eff ...

I. INTRODUCTIONWhile the inclusion of feed enzymes is routine in poultry fed sorghum-based diets, the effects of these enzymes are often muted or substandard, especially with phytase (Selle et al., 2018). The exact mechanism for this underperformance is not known, however, it is most likely caused by one or all of three key endogenous grain components: kafirin, phytate and phenolic compounds. Phen ...

INTRODUCTIONVariability in the nutritional value of feed ingredients for poultry (and indeed other livestock species) has been widely reported over several decades and has been the impetus behind a sustained body of research work. For example, Sibbald and Slinger (1962), Mollah et al. (1983), and Leeson et al. (1993) reported variation in the apparent metabolizable energy (AME) content of corn (3, ...

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 . The ...

A couple of quick remarks on this topic. When phytic acid is hydrolysed by phytase and the mucosal phosphatases in the intestine the only two direct products of this are myo-inositol and phosphate. We have measured the appearance of both of these in multiple experiments and this is clear evidence of phytase efficacy and its compatibility with endogenous phosphatases in the intestine. All additiona ...
