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 ...

Dietary protease supplementation has been observed to improve broiler growth performance and amino acid digestibility (Angel et al., 2011; Fru-Nji et al., 2011). Improvements in broiler energy utilisation have also been observed with supplemental protease (Sorbara, 2009; Freitas et al., 2011). These positive extra-proteinaceous effects may be influenced by age and diet type. In addition, these eff ...

INTRODUCTIONPoultry production is one of the largest sources of animal protein supply for human consumption in the world. For many countries, like Australia, chicken-meat is the dominant animal protein, therefore production must continue to expand to supply increasing demand. In Australia, for instance, per capita consumption of chicken-meat is predicted to increase by 7.9% over the next 5 years [ ...

Feed represents the primary cost of broiler production, thus the formulation of cost-effective diets that meet broiler nutritional requirements is critical. To ensure this objective is met, nutrient specifications of feed ingredients must be accurately determined. However, Australian broiler nutritionists have expressed concern, as many nutrient specification databases contain dated information or ...

INTRODUCTIONVariability in the nutritional value of feed ingredients for poultry (and indeed other livestock species) has been widely reported over several decades and has been the impetus behind a sustained body of research work. For example, Sibbald and Slinger (1962), Mollah et al. (1983), and Leeson et al. (1993) reported variation in the apparent metabolizable energy (AME) content of corn (3, ...

I. INTRODUCTIONThe withdrawal of antibiotics has caused an increased prevalence of necrotic enteritis (NE) in broiler chickens, making it the most common disease in the poultry-industry globally. Direct fed microbials (DFMs) have been shown to have great potential as alternatives to antibiotic growth promoters (AGPs). Bacillus amyloliquefaciens produces several extracellular enzymes including cell ...

Supplementing poultry diets with xylanase partially depolymerizes the xylans present in the dietary cereals, reducing the number of sugars in the molecular chains. The resulting oligosaccharides can be selectively fermented by beneficial intestinal bacteria, resulting in improved nutrient utilization (De Maesschalck et al., 2015). The study aim was to investigate the production of xylo-oligosaccha ...
