Poultry nutrition - Other additives
Alternative feed additives have promising importance in broiler production due to the ban on the use of certain antibiotics. The most used antibiotic alternatives in broiler production are phytogenics, organic acids, prebiotics, probiotics, enzymes, and their derivatives. Antibiotic alternatives have been reported to increase feed intake, stimulate digestion, improve feed efficiency, increase growth performance, and reduce the incidence of diseases by modulating the intestinal microbiota and immune system, inhibiting pathogens, and improving intestinal integrity. Simply, the gut microbiota is the target to raise the health benefits and growth-promoting effects of feed additives on broilers. Therefore, naturally available feed additives are promising antibiotic alternatives for broilers.
Summary A trial was conducted to test the following hypothesis; broiler exposure to coarse insoluble fibre in the diet or litter will result in enhanced gizzard function and performance, improved adaptability to an intermittent feeding program and an increase in the occurrence of reverse peristalsis. Ross 308 broiler chickens were either intermittent or ad libitum fed a basal diet, a basal diet diluted with 15 % coarse hulls (barley and oats) or a basal diet...

A study was conducted to evaluate effect of high levels of corn DDGS and rye on growth performance and gut health of broilers as influenced by a nonstarch polysaccharides (NSP) degrading enzymes blend (CIBENZA ® CSM, Novus International, Inc.). The study consisted of 8 treatments: corn soy control, 30% DDGS, 16% corn bran, 38% rye, 38% rye plus enzyme, 25% rye, 25% rye 30% DDGS, and 25% rye 30% DDGS plus enzyme. Corn bran...

One battery study was conducted to evaluate effect of a synthetic 1:1 thymol carvacrol blend (NEXT ENHANCE® 150) on growth performance and gut health of broilers fed rye wheat based diet and challenged with mixed species of Eimeria on day 0. A rye wheat and soybean meal based diet was formulated to meet or exceed nutrient requirements of broilers. To this basal diet, the essential oil blend was added at 0, 30, 60, or 120...

Introduction Intestinal colonization and shedding of pathogenic bacteria in animal feces is an important issue in both human food safety and animal health. Animal feed due to its composition provides a favorable environment for the growth of various microorganisms. Microorganisms found in feedstuffs can be saprophytic, pathogenic, conditionally pathogenic and toxic. Their proliferation and growth in the feed depends on...

Introduction The impact of gastrointestinal disease ranges from erosive to catastrophic, and considerable time, effort and financial resources are devoted to limiting the risk and consequence of disease challenge. Intense breeding and selection programmes have provided birds with the genetic potential to perform in the face of disease challenge, while good biosecurity has reduced the risk and consequence of infectious disease. At the...

INTRODUCTION The utilization of leaf meal feed ingredient as alternative is not new but the inclusion level at various ages and physiological conditions varies. The green plants have long been recognized as the cheapest and most abundant potential source of proteins because of their ability to synthesize amino acids from a wide range of virtually unlimited and readily available primary materials [1]. Any assessment...

Feeding of poultry has become more innovative as the conversion of feed to poultry production is more efficient than ruminant. Unlike dairy, poultry products like meat and egg are energy dependant on synthesis as the major energy component is utilized for oxidative energy. It is assumed that out of 3200 kcals ME 1500 Kcals is used for the body maintenance and 800 kcals for products synthesis. The incorporation of carbohydrates into chicken meat or egg is insignificant as the composition is with...

Introduction In the late 1930’s and early 1940’s not a single childbirth was reported during a period of ten years in one area of China. It was found that for economic reasons villagers had switched from cooking with soybean oil to crude cottonseed oil (Liu, 1957). Women suffered from amenorrhea and men were impotent. These epidemiological findings led to clinical studies...

ABSTRACT This study was conducted to determine the effects of organic and inorganic chromium (Cr) supplementation on performance parameters, eggshell quality and some serum parameters of laying Pharaoh quails (Coturnix coturnix Pharaoh). Laying quails(n: 360; 59 days old) were randomly divided into three experimental groups each including 120 birds. Basal diet applied to control group was based on corn-soybean meal without additional organic or...

Introduction Poultry are monogastric animals, which depend on highly digestible feed ingredients to improve their growth performance and health. Energy-providing feed (such as maize or corn) and body building food like soybean and groundnut in form of cake as protein sources are required by poultry (birds). However, these feedstuffs are stable food for many people. In Nigeria, soybean is...

Introduction
Previous studies have demonstrated that a metabolizable energy (ME) value of 50 kcal/kg could be attributed to 100 ppm of an encapsulated blend of cinnamaldehyde, carvacrol and capsicum oleoresin (XT, XTRACT® 6930 – Pancosma). In addition, work with phytonutrients has shown that the improvement in performance is closely associated to changes in intestinal microflora, and improvement in digestion...
