Special Issue Information

Dear Colleagues, 

Current feed ingredient evaluation for pigs and poultry depends primarily on nutrient digestibility values. These values are based on experimentally determined ileal and total tract measurements, which result in static digestibility coefficients for nutrients in different feed ingredients. The use of digestible nutrients in feed formulations has resulted in significant improvements in feed efficiency and reductions in nutrient excretion into the environment. Digestible nutrients, however, do not provide information on the rate of nutrient digestion nor the exact location of digestion along the gastrointestinal tract. Therefore, evaluating feed ingredients for both the extent of nutrient digestion and the rate of nutrient digestion may be vital to further improving nutrient utilization by pigs and poultry. Furthermore, nutrient digestion kinetics may be used to improve the gut health of pigs and poultry because attention is paid to the nutrient needs of specific sections of the digestive tract, the dynamic nature of these nutrient needs, and the interaction with the gut microbiome.

The aim of this Special Issue is to highlight nutrient digestion kinetics in feed ingredient evaluation for pigs and poultry through contributions in the form of original research articles, meta-analyses, and literature reviews. We welcome studies on techniques (in vitro, in vivo, other) for determining nutrient digestion kinetics in feed ingredients and diets, specific locations of nutrient digestion along the gastrointestinal tract, and rate of passage in pigs and poultry. We also welcome studies on the growth performance and gut health of pigs and poultry fed ingredients or diets that differ in nutrient digestion kinetics.

This review considers the conversion of dietary protein and amino acids into chicken-meat protein and seeks to identify strategies whereby this transition may be enhanced. Viable alternatives to soybean meal would be advantageous but the increasing availability of non-bound amino acids is providing the opportunity to develop reduced-crude protein (CP) diets, to promote the sustainability of the chicken-meat industry and is the focus of this review. Digestion of protein and intestinal uptakes of amino acids is critical to broiler growth performance. However, the transition of amino acids across enterocytes of the gut mucosa is complicated by their entry into either anabolic or catabolic pathways, which reduces their post-enteral availability. Both amino acids and glucose are catabolised in enterocytes to meet the energy needs of the gut. Therefore, starch and protein digestive dynamics and the possible manipulation of this ‘catabolic ratio’ assume importance. Finally, net deposition of protein in skeletal muscle is governed by the synchronised availability of amino acids and glucose at sites of protein deposition. There is a real need for more fundamental and applied research targeting areas where our knowledge is lacking relative to other animal species to enhance the conversion of dietary protein and amino acids into chicken-meat protein.
