Reviews made on the impact of intermittent lighting (IL) on broiler performance (Buyse et al., 1996; Rodrigues and Choct, 2017) attest to the consistency of such lighting programs in achieving better feed conversion rates. So far, no research has been conducted to assess the impact of IL on the susceptibility to and recovery from infectious diseases. We hypothesized that an IL program would increa ...

I. INTRODUCTIONNecrotic enteritis (NE) is of great concern to the poultry industry due to its deteriorating impact on production and increasing mortality, resulting in a US$6 billion global economic loss (Wade and Keyburn, 2015). The causative agent of NE is Clostridium perfringens, a gram-positive spore-forming anaerobic bacterium. The subclinical form of NE is financially more devastating than t ...

Growth promoting effects of zinc bacitracin, Bacillus-based probiotics and a blend of Yucca and Quillaja saponin in broilers have been well documented (Engberg et al. 2000; Cheeke, 2009; Jeong and Kim, 2014). These in-feed additives are commonly used in broiler diets but their effects at different dietary crude protein (CP) concentrations remain unclear. This study was conducted to study the effec ...

Measures to improve bird performance have been sought due to the imminent phase out of in-feed antibiotics in poultry and continued demand for higher poultry feeding efficiency. Promotion of gizzard development by physical structure of feed ingredients or addition of dietary fibre is one such strategy with the hypothesis that larger ingredient particles and higher fibre enhance digestive enzyme se ...

I. INTRODUCTIONNSP refer to a wide variety of polysaccharide molecules of cell walls with varying degrees of water solubility, size and structure. Their physiological functions are defined by whether they are water soluble or insoluble. The amount of soluble and insoluble NSP varies greatly among different ingredients; for example, corn and sorghum contain very low levels of NSP but wheat, rye and ...

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 ...
