IntroductionRecently, higher dietary arginine (Arg) levels than the recommended values in nutritional tables have been reported (Murakami et al. 2012; Xu et al., 2018; Zampiga et al.,2018; Oliveira et al., 2022). This suggests that Arg levels needed for maximum performance are increased in modern broilers. The high dietary Arg levels found in the literature may be associated with the critical role ...

Fibre is a nutrient that has been largely ignored in feed formulation, not because it is unimportant, but because it is not well known what ‘fibre’ actually stands for. Firstly, the terms used to describe fibre in feed are confusing and the values they represent are inaccurate. For instance, ‘crude fibre’ is a 19th century relic that does not mean much in monogastric animal ...

INTRODUCTIONProviding adequate quantities of animal protein to meet the demands of a continuously growing population requires that livestock producers must increase the production efficiency of farm animals. This can be achieved through improved genetics, management, and nutrition. Furthermore, feed ingredient prices continue to increase, resulting in minimizing the profit for the producers and fo ...

INTRODUCTIONCereal grains and vegetable protein sources contain between 10-75% of non-starch polysaccharides (NSP). NSP in cereals form part of the cell wall structure and in vegetable proteins, such as legumes, may also play a role as an energy storage material. As far as monogastric animal nutrition is concerned, NSP as the major part of fibre (fibre is the sum of NSP and lignin) are regarded as ...

Broiler chickens spend one third of their lives developing inside an egg. Hence, understanding and optimising the in ovo environment is fundamental. The pH of body fluids is tightly regulated to maintain critical physiological functions such as gas exchanges. Enzymes equally have an optimum pH range that determines their efficiency. Changes to these conditions, may impact on the efficiency of O2 t ...

Jeyashree Elango (University of Delaware)     Enteroids provide a 3-dimensional microenvironment of the intestine, acting as a miniature model for understanding intestinal functions and immune responses. Hence, this shows a promising application in studying disease models and drug screening, among others. Salmonella enterica serovar Typhimurium is one of the food-borne pathogens aff ...

Theresia Lavergne (Natural Biologics)     To produce resilient and healthy poultry, it is necessary to understand the effects of diet and dietary feed additives on the microbiome and its development. This trial was conducted to evaluate the microbiota of broilers 14, 28, and 42 d of age, while feeding them a combination of yeast postbiotics and fermentation extracts (Provillus 4Poul ...
