“…In broiler commercial production, the main goal of broiler producers is to produce high-quality meat at a low cost per unit (Singh, et al, 2017). Poultry nutrition experts are constantly looking for the best approaches to reduce the cost of the feed, which is constantly changing due to the demand to raise production performance (De Keyser, et al, 2016). Corn and soybeans are one of the primary raw materials used to formulate chicken diets that have the ability to cover most of this diet's energy and protein needs.…”

Objective: The prime objective of this study was to evaluate the effects of feeding low energy diets and non-starch polysaccharides (NSP) enzymes on some growth-and carcass-related parameters in broilers. Methods: A total of 240 chicks (1 day of age) were randomly allocated to two groups, each comprising 6 replicates of 20 chicks. The birds were fed two diets, optimum control (23, 21 and 19% CP by 3000, 3040, 3140 kcal/kg of diets without NSP enzymes supplementation) and low ME (23, 21 and 19% CP by lowering 60 kcal/kg from each optimum ME level plus 100g/ton of NSP enzymes supplementation) during starter, grower and finisher periods, respectively. Results: Compared to the control treatment, no significant difference (p > 0.05) in body weight gain, feed intake, and feed conversion ratio was observed with the low ME diet with NSP enzymes supplemented. Also, dietary low ME with NPS enzymes supplementation did not affect carcass, breast, and thigh muscles (p > 0.05). Nevertheless, the NSP enzymes supplementation to low ME broilers diets did not decrease the total cholesterol and triglyceride plasma concentration. Furthermore, neither aspartate aminotransferase, alanine aminotransferase glucose, total protein nor albumin were significantly changed. Conclusion: The supplementation of NSP enzymes is needed to support the performance and physiological activities of the broilers when fed the dietary low energy diets. However, no adverse effect such as lower lipid profile was observed when NSP enzymes supplementation with low ME diets were simultaneously applied in this study.

“…The improved feed efficiency of corn-based diets by means of NSPase degrading enzymes was associated with a higher starch and protein availability in broilers [35,60]. Also digestible amino acid and total protein reformulation using XG was demonstrated previously, in a 42-d broiler experiment using corn/wheat SBM [64], showing the possibilities of lowering the N output by limiting the protein and digestible amino acid input. Besides improved nutrient utilization of soluble and insoluble type ingredients, XG may exert different other roles throughout the digestive tract.…”

This study consolidates the efficacy of a non-starch polysaccharide (NSP)ase enzyme-concept in corn and wheat-based broiler diets. The NSP building blocks of corn, wheat and soybean meal (SBM, 44% protein) were studied first. Cereal NSP primarily consists of arabinose, xylose and glucose molecules that form arabinoxylan, β-glucan and cellulose polysaccharides. In soybean meal (SBM), glucose (cellulose) predominates, next to galactose and uronic acids that form "pectins". Broiler performance progress using in-feed NSPase enzymes depends on the concentration, complexity and solubility of the substrate and the genetic potential of the animal, mainly. A dual NSPase enzyme-concept for cereal and SBM NSP, predominantly being arabinoxylan, β-glucan and cellulose, was developed. Methods for measuring enzyme activities (endo-1,4-β-xylanase (EC 3.2.1.8) and endo-1,3(4)-β-glucanase (EC 3.2.1.6)) were developed (AVEVE Biochem UNITS) and preparations thereof (XG) standardized to meet requirements for most challenging NSP (corn, barely soluble). Feed intake (FI), bodyweight gain (BWG) and feed:gain ratio (F:G) were assessed in three zootechnical studies, each using 160 Ross 308 broilers split in two feeding groups with 80 birds/group (10 replicates of eight) for 42 d (starter/grower period). Respective corn-SBM, wheat-SBM and corn/wheat-SBM diets were used as negative control (NC) or added with the enzyme-concept (XG). In the total period, XG ameliorated BWG and F:G compared to NC in each study, where BWG increased best in diets with corn and F:G lowered most in diets with wheat. The dual NSPase enzyme-concept offers ingredient flexibility in present setting by enhancing the nutritional content of corn, wheat and SBM, expectedly from cleaving major NSP target molecules. Thereby, broiler professionals increase feed formulation liberty and safety and production result simultaneously.

“…In this work, the main contributor to differences in the community structure was the cereal supplementation. Wheat-based diets contain a high concentration of non-digestible polysaccharides, causing the need for supplementing enzymes like xylanase-glucanase mixtures to improve digestibility ( Keyser et al, 2016 ). This could influence the activities and the composition of the microbial structure.…”

Caeca Microbial Variation in Broiler Chickens as a Result of Dietary Combinations Using Two Cereal Types, Supplementation of Crude Protein and Sodium Butyrate

The intestinal microbiome can influence the efficiency and the health status of its host’s digestive system. Indigestible non-starch polysaccharides (NSP) serve as substrates for bacterial fermentation, resulting in short-chain fatty acids like butyrate. In broiler’s nutrition, dietary crude protein (CP) and butyrate’s presence is of particular interest for its impact on intestinal health and growth performance. In this study, we evaluated the effect on the microbial ecology of the ceca of dietary supplementations, varying the cereal type (maize and wheat), adequate levels of CP and supplementation of sodium butyrate on broiler chickens with 21 days. The overall structure of bacterial communities was statistically affected by cereal type, CP, and sodium butyrate (p = 0.001). Wheat in the diet promoted the presence of Lactobacillaceae, Bifidobacteriaceae and Bacteroides xylanisolvens, which can degrade complex carbohydrates. Maize positively affected the abundance of Bacteroides vulgatus. The addition of CP promoted the family Rikenellaceae, while sodium butyrate as feed supplement was positively related to the family Lachnospiraceae. Functional predictions showed an effect of the cereal type and a statistical significance across all supplementations and their corresponding interactions. The composition of diets affected the overall structure of broilers’ intestinal microbiota. The source of NSP as a substrate for bacterial fermentation had a stronger stimulus on bacterial communities than CP content or supplementation of butyrate.
