1. IntroductionMycotoxins are fungal-generated secondary metabolites that are ubiquitous and unavoidable contaminants of food and feed, and their consumption by humans and animals results in diseases and death. Several species of the genus Aspergillus, Penicillium, and Fusarium are capable of producing mycotoxins (Cole & Cox, 1981). For instance, Aspergillus flavus, A. parasiticus, A. nomius, ...

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 ...

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 ...

BackgroundControl and eradication of intestinal infections caused by protozoa are important biotechnological and medical challenges worldwide. The coccidial parasites Eimeria, Toxoplasma, Neospora and Cryptosporidium are the cause of serious diseases in humans and animals. Many of these intracellular protozoa affect the small intestine and produce devastating effects on immune compromised subjects ...

IntroductionCurrent broiler growth rate is partly the result of an intense genetic selection;1 therefore, feeding is important to achieve the maximum productive expression. Success attained until now in this practice has been due to better knowledge of the functions that different nutriments carry out, which in turn allows higher precision when establishing nutrimental needs.2 To be able to feed c ...

IntroductionAfter the fermentation process of corn to produce ethanol, the remaining fat in the by-product distiller’s dried grains with solubles (DDGS) is extracted by centrifugation. The resulting by-product is known as low-fat DDGS, which has slightly higher protein content, amongst other nutrients, compared with conventional DDGS (Kshun and Kurt, 2012). The fat extraction in low-oil DDGS ...
