Fiber in poultry nutrition
Dietary fiber (DF) was considered an antinutritional factor due to its adverse effects on feed intake and nutrient digestibility. However, with increasing evidence, scientists have found that DF has enormous impacts on the gastrointestinal tract (GIT) development, digestive physiology, including nutrient digestion, fermentation, and absorption processes of poultry. It may help maintain the small and large intestine’s integrity by strengthening mucosal structure and functions and increasing the population and diversity of commensal bacteria in the GIT. DF is composed of non-starch polysaccharides (NSP), oligosaccharides, and lignin that scape digestion and enzymatic hydrolysis. Increasing DF content benefits digestive physiology by stimulating GIT development and enzyme production. And the inclusion of fiber at a moderate level in diets also alters poultry growth performance. It improves gut health by modulating beneficial microbiota in the large intestine and enhancing immune functions.
INTRODUCTION Globally, corn becomes a major ingredient for animal feed either as whole grain or by-product from corn milling industries. There is several corn co-products derived from wet or dry corn milling industries (Tangendjaja & Wina, 2007) and at least 2 co-products commercially available in Indonesia for poultry feed, namely corn gluten meal (CGM) and dried distillers grains and soluble (DDGS). CGM is a co-product obtained during wet milling process to produce maize...

1. Introduction There is a tremendous interest in the understanding of immune response against pathogens and toxins on the gastrointestinal tract (GIT) of the birds due to in this specialized system, as it harbors 70 to 80 percent of the avian immune cells and molecules [1]. Additionally, there is an overwhelming interest in finding new alternatives to antibiotic growth promoters (AGP) because of regulations and consumer preference in many countries which these strategies are...

1. Introduction To preserve the potency of clinically important antibiotics, there has been a gradual reduction and an anticipated elimination of their use in food-producing animals including broiler chickens [1]. Consequently, farmers are faced with the challenge of maintaining productivity and preventing diseases on their farms [2]. Therefore, there is a need for alternative strategies including dietary means to promote gut health and growth performance of broiler chickens....

Introduction Barley ranks fourth in global cereal production after corn, wheat and rice. About 65% of the world’s barley produced is fed to animals, including poultry. Australia is a significant global producer of barley, ranking in the top five countries with about 5% of global production and is among the top three barley exporters accounting for about 30% of malt and 20% of feed barley trade. Australia is a reliable supplier of two row...

I. INTRODUCTION Globally, maize and wheat are the major cereal grains used in broiler feed. Maize is predominant in Asia and the Americas, whereas wheat is in Australia, New Zealand and Europe. Extensive research has been undertaken in refining dietary strategies to optimise broiler performance when offered reduced crude protein (CP) diets. In feed, these grains have been optimized by the inclusion of feed enzymes and unbound (crystalline or synthetic) amino acids. Reduced CP...

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 source. The potential consequence of this is an incorrect prediction of the digestible energy...

I. INTRODUCTION Cereal grains are ground prior to feed mixing to reduce the particle size with the aim of modifying their physical characteristics. This facilitates handling, mixing and further processing (extrusion and pelleting) and increases the exposure of nutrients in the endosperm to digestive enzymes (Amerah et al., 2011). Available recommendations regarding optimum particle size are contradictory, due to...

INTRODUCTION The physical form of the diet is a tool to improve broiler live performance, especially feed efficiency. However coarse feed particles enhance gizzard function, which was referred to as the pacemarker of gut motility (Xu et al. 2015a, Xu et al. 2015b, Kheravi et al. 2017). Studies respect to particle size impact on health, digestive efficiency and broiler performance were developed more than 60 years ago (Pacheco et al. 2014, Xu et al. 2015a, Xu et al. 2015b)....

Introduction Wheat and barley as alternative cereals can be successfully replaced with corn in poultry diets. These grains could locally grow in many areas of the world and have lower water requirements than corn (Ravindran et al. 1999; Lin et al . 2010). The major components of wheat and barley are starch and proteins, though they have considerable content of non-starch polysaccharides (NSP), derived from the cell walls (Olukosi et al . 2007;...

INTRODUCTION The continued use of antibiotics in feed has led to the emergence of antibiotic-resistant pathogenic organisms, which is a major concern in the poultry industry (Diarra et al., 2007; Garcia-Migura et al., 2014; Roth et al., 2019). Therefore, the use of in-feed antibiotics has been reduced, and the identification of alternative strategies to antibiotics has become a primary research focus. Comparisons of alternatives to antibiotics on gastrointestinal health, shown...

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-oligosaccharides (XOS) in different batches of Australian wheat, in the presence or absence of xylanase....

I. INTRODUCTION Metabolizable energy (ME), digestible amino acids (dAA) and available phosphorus (avP) are the largest and most expensive components in broiler diets, considerable fractions of which still pass through the digestive tract undigested and are lost via excretion (Ravindran et al., 2013), hence, emphasizing the need for higher nutrient usage efficiency than current practice. Ability of carbohydrases to degrade non-starch polysaccharides and liberate caged starch and...

I. INTRODUCTION Improved FCR was observed in broiler chickens fed a slow digestible starch diet compared with a fast digestible starch diet (Weurding et al., 2001). Furthermore, Enting et al. (2005) indicated that a slow digestible starch diet fed to broiler chickens can spare amino acids (AA). Finally, Liu et al. (2017) and Truong et al. (2017) concluded that starch digestion kinetics play a role in broiler performance, but that protein digestion kinetics may be more important...
