INTRODUCTIONSoybean meal´s good amino acids (AA) balance makes it an excellent protein source in poultry diets, although it does have the disadvantage of containing antinutritional factors such as trypsin inhibitors and lectins. These can negatively affect animal growth if the SBM is not adequately processed(1) using a proper cooking time and temperature to deactivate these factors(2). Exces ...

INTRODUCTIONSoybean meal (Glycine max) is a widely used ingredient in livestock feed for its excellent protein content. Its production in Mexico is for use in the livestock industry, and is limited by the small scale of domestic soy bean production. Only 3 % of soybean meal demand is met by domestic production, the remaining 97 % coming from imported raw material(1). Despite its excellent protein ...

INTRODUCTIONThe physical form of the diet is a tool to improve broiler live performance, especially feed efficiency. However coarse feed particles enhance gizzard function, which was referred to as the pacemarker of gut motility (Xu et al. 2015a, Xu et al. 2015b, Kheravi et al. 2017). Studies respect to particle size impact on health, digestive efficiency and broiler performance were developed mor ...

INTRODUCTIONThe inclusion of fats and oils in broiler chicken diets is a common practice because they provide essential fatty acids, improved the absorption of soluble nutrients in oil and increased the content of metabolizable energy (ME) in the diets (Hossain and Das, 2014). Feeding programs are established based on EM needs, so nutritional strategies are sought to optimize productivity consider ...
