Enzymes in poultry nutrition
Enzymes are proteins involved in all anabolic and catabolic pathways of digestion and metabolism. Digestive enzymes are categorised as endogenous or exogenous. Endogenous enzymes are produced by the animal and exogenous enzymes are administered from outside. Enzyme supplementation decreases nutrient loss through excreta, reduces diets nutritional levels, improves nutrient availability; thus, enhances production efficiency and profitability. In addition, exogenous enzymes hydrolyse non-starch polysaccharides, increase the usage of feed energy, reduce negative impacts of non-digestive residues on digesta viscosity, and improve gut microbial ecosystem. Cellulase, glucanase, pectinase, xylanase, galactisidases, phytase, non-starch polysaccharides degrading enzymes, amylase, lipase, cellulase, and protease are the most common enzymes used in poultry feed.
Introduction The efficient use of feed is extremely important in broiler production. Investigations have to be continued to decrease cost of broiler production and improve broiler performance. Pellet feed has been shown to have the greatest potential to improve feed conversion ratio (FCR) and reduce cost compared to mash feed (Maiorka et al. 2005, Salari et al. 2006, Amerah et al. 2008). These improvements have been associated with changes in nutrients, digestibility and less...

INTRODUCTION Aflatoxins belong to a group of mycotoxins produced as secondary metabolites by fungi of the Aspergillus genus, especially A. flavus, A. parasiticus and A. nomius (Kurtzman et al., 1987). No region of world escapes the problem of mycotoxins and according to Lawler and Lynch (2005) mycotoxin are estimated to affect as much as 20% of world’s crop each year. Crops grown under warm and moist weather in tropical or subtropical countries are especially more...

Poultry industry suffers greatly from the economic losses due to the adverse effects of mycotoxicosis attributed to reduced feed intake, poor feed conversion and nutrient utilization, growth and production performance, immunosuppression and subsequently increased susceptibility to various infections (Xue et al. 2010). Aflatoxin is the most commonly occurring mycotoxin in India. Major forms of AF include B 1 , B 2 , G 1 , and G 2 , while AFB 1 is...

Over the past several years, organic poultry production has been rapidly expanding (Rogenburg et al., 2008). This alternative to conventionally produced poultry meets consumers’ expectations for healthier animal protein sources (ATTRA, 2010). According to standards set by the U.S. Department of Agriculture (USDA) National Organic Program, to be certified “organic poultry,” birds must be raised with outdoor access, fed certified organic feed, and should not be fed with feed...

Introduction The rapidly increasing human population particularly in the developing world has increased the demand for animal protein, especially for pork and poultry products, for human nutrition (World Bank Group 2015). This is an opportunity for smallholder farmers in Africa to increase household income and improve their livelihoods by connecting with the livestock and poultry value chain. Poultry production, in particular, has a potentially great role to play in terms of...

INTRODUCTION Globally, different energy and amino acid levels are used in different regions, although it is unknown the magnitude by which these dietary nutrients are influenced by feed cost or biological nutrient requirements. Furthermore, a study that explains nutrient trends, body composition and nutrient efficiency in one systemized approach over time as a way to gain insight into the future should shed light on biological mechanisms in modern broiler chickens. As...

Introduction The inclusion of exogenous enzymes in broiler diets has been increasingly intensified with the objective of maximizing nutrient utilization and reducing feed costs, thus improving dietary, nutritional and energy levels (Adeola & Cowieson, 2011). Exogenous enzymes improve the nutritional value of feed ingredients due to the degradation of specific bonds not efficiently hydrolyzed by the endogenous digestive enzymes of birds and to the degradation of...

Abstract
A battery study was conducted to evaluate the efficacy of phytase superdosing in improving growth performance, pancreatic response, and nutrient digestibility of broilers with a high trypsin inhibitor model. There were 5 dietary treatments: positive control (PC), negative control 1 (NC1), NC1+ 1500 U/kg phytase, negative control 2 (NC2), and NC2 + 1500 U/kg phytase. In NC1 and NC2, the SBM was substituted with full fat extruded soybeans to target the trypsin...

Three recent feeding studies confirm that supplying laying hens with adequate dosages of a methionine is necessary to optimize performance, but moreover, products of the methionine-hydroxy analog (liquid MHA-FA; MHA-Ca) are interchangeable with DL-methionine at a ratio of 100:65, without having any negative effect on egg production performance. Assessment of the relative bioavailability of MHA products should be reflected both in the respective dosages and in the purchase price of the...

In the United States, the largest poultry-producing country globally, broiler production decisions are based on the smallest of margins, often as little as a fraction of a penny per pound. With such thin margins separating producers, bird performance is a key indicator of success. Producers can support gut health and overall profitability by supplementing broilers with a methionine source that can protect performance by improving feed conversion ratio (FCR),...
