INTRODUCTIONIt is imperative to identify factors that inhibit the digestibility of nutrients for successful commercial poultry production. The non-starch polysaccharides (NSP) like substances of hemicellulose, cellulose, and pectin can reduce nutrient digestibility in poultry (Choct, 1999). Among the NSP, β-mannans are a group of hemicelluloses, which are present in many ingredients used for ...

The following article is a special collaboration from AFMA (Animal Feed Manufacturers Association) www.afma.co.zaWe thank their kind support.SummaryEnzymes have been used in the feed industry for more than 30 years. Traditional applications have included improving the digestibility and bird performance of ingredients such as barley and wheat. As our understanding of the anti-nutritive factors that ...

A study was conducted to investigate whether the functional oligosaccharides released in situ as a consequence of fibre-degrading enzyme application ameliorate the severity of necrotic enteritis (NE) in broilers offered wheat- or maize-based diets. Day-old Cobb 500 mixed-sex broilers (n = 1536) were assigned to a 2 × 2 × 4 factorial arrangement of treatments, with six replicates per tr ...

1. IntroductionTrace minerals such as zinc (Zn), manganese (Mn), and copper (Cu) play critical roles in bone formation and eggshell quality [1,2]. Zn supports bone and cartilage integrity by facilitating collagen formation and hydroxyapatite crystallization [3], while Mn contributes to bone development by activating enzymes involved in synthesizing mucopolysaccharides in bone cartilage [4,5]. Cu i ...

The purple race of Zea mays L. is a native plant from America. It was one of the main foodstuffs of indigenous peoples in the pre-Columbian era, and several medicinal properties have been attributed to it; hence its industrial and export potential. Chemical components of the purple maize are essences, salicylic acid, fats, resins, saponins, potassium and sodium salts, sulfur and phosphorus, and es ...

All commercial poultry eat with reasonably good precision to balance nutrient intake with requirements. Short term, there can be some variation in feed intake related to local situations, but long-term, the mechanisms of feed intake regulation are quite precise. Matching nutrient needs with intake is an obvious inherent evolutionary necessity to ensure survival and reproduction. A bird’s dai ...

With the ever increasing need for animal protein sources for human consumption, the poultry industry always coped up to meet the needs at an affordable manner. The conditions in developing countries for the production of either broiler or table egg may not be entirely free of unseen losses. The following article will review briefly about such losses by gut disorders and the approaches to avoid the ...
