The formation of a viscous gut content in the small intestine due to the presence of non-starch polysaccharides in feed can markedly restrict efficient nutrient digestion in poultry. This adverse effect may be mediated through the supplementation of exogenous feed additives. The present study investigated the effects of carbohydrases and a buffered formic acid on growth performance and ileal diges ...

Feed additives have a promising impact on broiler production in improving performance and reducing the incidence of diseases in the post-antibiotic era (Ayalew et al. 2022). However, there are limited data that illustrate the effect of feed additives on broiler performance under necrotic enteritis (NE) challenge. Therefore, this study was conducted to determine the impact of an enzyme (xylanase, 3 ...

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 ...

Nutritional strategies to improve performance of broilers offered reduced crude protein (RCP) diets supplemented with crystalline amino acids are of interest to the poultry industry. We hypothesized that the dietary inclusion of moderate amounts of insoluble fibre would stimulate gizzard function and increase the retention time of digesta in the foregut allowing more time for exogenous protease to ...

Recent studies have shown that the decreased performance of broilers associated with feeding a reduced crude protein (RCP) diet cannot be fully recovered by supplementing essential amino acids (Hilliar et al., 2019). We hypothesized that the dietary inclusion of moderate amounts of insoluble fibre would improve gizzard function and protein/amino acid digestibility that could help to restore the pe ...

Field pea (Pisum sativum) is a good source of protein but can also provide energy due to high starch content (Petterson et al., 1997). The slowly digestible starch in pea may improve energy utilization in broilers because of the prolonged elevated plasma glucose levels (Enting et al., 2005). Thus, partial replacement of soybean meal and wheat with pea may affect the net energy value of the diet. T ...

Starch is the most abundant source of energy in broiler diets, providing about 50 % of apparent metabolisable energy. Broiler diets generally contain approximately 40 % starch, which is thought to be completely digested within the small intestine. However, the microbiota in the large intestine also plays an important role in starch digestion, producing volatile fatty acids that act as an energy so ...
