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.
The increasing household incomes of consumers across the world and their willingness to spend on food products has led to a growing intake of meat. This has given rise to consistent efforts by the livestock owners to effectively look after the health and hygiene of the animals along with the provision of functional and supplementary components in their feed. One such element that is marking its presence in animal feed is yeast as it shows immense potential in enhancing animal growth...

Introduction The application of sub-therapeutic doses of growth-promoting antibiotics (GPAs) in the poultry industry has allowed the development rate and production yield of the birds to be increased while preventing infections [1] by changing their intestinal microbiota, metabolism, and intestinal function [2]. Feeding is a particularly important factor in commercial poultry farming as it represents approximately 70% of the total cost of production, which has led to increased...

DESCRIPTION OF PROBLEM Creatine is a necessary component in energy metabolism, supplying phosphate groups to adenosine diphosphate and recycling them to adenosine triphosphate (ATP) that can be used for maintenance and growth. This creatine-ATP recycling system does not occur in all cells, only in those where there is great variability in energy demand, including muscle cells [1]. Creatine is especially important in growing animals such as broiler chickens, as it is not only...

I. INTRODUCTION The use of feed additives such as those based on essential oils or organic acids is increasing in poultry production as a result of a number of factors including legislation on restricting antibiotic use and consumer preferences for more natural, welfare friendly poultry production. Formic and propionic acid products have a strong antimicrobial activity and have been shown to improve bird performance and positively influence the gut microbiota (Emami et...

Biological interplay between microbes and animals is based on molecular interactions. So, we know that pathogens attach to specific carbohydrate structures. What if we knew more about those target structures? This would bring development of pathogen binding supplements to the next level. Dr. H. tells about recent research presented at the EAAP’s 71st annual meeting. The poster entitled “N-glycan profiling of chicken intestine as a tool for designing improved feed supplements” presented an...

INTRODUCTION Heritage chickens are important for breeders and industry to protect valuable genes and traits over the long term. However, 50% or more of the genetic diversity is absent in commercial pure lines (FAO, 2007; Muir et al., 2008). Therefore, preserving potentially valuable genes by conducting research with heritage breeds is important. Changes in live weight and proportional growth of body components as affected by genotype and environmental factors are defined as...

Summary This paper discusses the use of alternative feed ingredients in poultry nutrition. The importance and limitations, particularly the presence of anti-nutritive factors, of such ingredients are highlighted. The results of a series of studies recently completed or ongoing at the University of New England, Australia, suggest that the nutritive value of such ingredients can be improved through supplementation with microbial enzymes. As it is...

1. Introduction Recently, oxidative stress has become a major concern as a life threatening and a chronic-disease mediator [1–3]. The reactive oxygen or nitrogen species (ROS, RNS) are normally generated during the respiratory chain reaction in the mitochondria. Nevertheless, the excessive production of such ROS and RNS induces oxidative stress, homeostasis imbalance and subsequent pathological conditions [4]. Bacterial infection activates immune cells and induces...

DESCRIPTION OF PROBLEM Broiler diets are mainly composed of vegetable feedstuffs. These ingredients usually consist of high amount of P in the phytate form (60 to 80%). The phytate form that is found in plants is mostly unavailable to be used for broilers [1]. Phytate is negatively charged under many pH conditions, and because of this property, phytate can form complexes with positively charged molecules and reduce their digestibility. Forming complexes with other nutrients can...

SUMMARY The objective of this study was to investigate the utilization of energy as well as performance of broiler chickens on diets based on cassava chips and pellets with or without enzyme supplements. Feed intake to day 21 was lower (P < 0.01) on the diet containing cassava chips than on diets with maize or cassava pellets, in spite of enzyme supplementation and enzyme supplements improved (P < 0.01) feed intake...
