corn, nonstarch polysaccharide, energy, variability
Corn is the most common feed ingredient used in poultry nutrition. Maize contributes with up to 65% of the metabolizable energy and 20% of crude protein in poultry diets (Gehring et al., 2013; Dei, 2017). Its average nutritional value is well-known, but it is accepted that the variability in its composition and energy value is a very common issue with great impact on poultry performance and health (Cowieson, 2005; Gehring et al., 2013; Latham et al., 2016; Montanhini-Neto et al., 2017). Corn variability affects growth, feed conversion, flock uniformity, digestibility, AMEn, digesta viscosity, gut microbiota composition, intestinal health, and efficacy of exogenous enzymes (Latham et al., 2016; Williams et al., 2017; Cordova-Noboa et al., 2020, 2021 a, b; Franciele et al., 2021, Giacobbo et al., 2021; Melo-Duran et al., 2020, 2021a, b). This presentation will address recent advances in understanding the effects of corn variability.
