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.
From 2Q onwards, the chemical industry upward trend was verified as a set one. Prices of more than 40 critical chemical raw materials showed an increase. At that time, there were also some raw materials with market prices falling. As of May 20, the market for...

1. Introduction Carotenoids are natural pigments which are responsible for yellow to red colour observed in plants and vegetables (Mortensen, 2006). Carotenoids are important for its various roles in human and animals, these include immune functions, decrease in the risk of disease and antioxidant function (Johnson, 2002; Rao & Honglei, 2002; Hinds et al., 1997). There are over 700 carotenoids (Junpatiw et al., 2013); one of which is the β-carotene. β-carotene can...

Evidence of the development of antibiotic resistant strains of bacteria that are pathogenic to humans has mounted over recent decades; and the practice of using sub-therapeutic levels of antibiotics as growth promoters (AGP) in livestock production has been heavily implicated in this resistance. Worldwide, this connection has led to erosion of consumer trust in agricultural practices that rely on this valuable medical resource. Increasingly, legislation is...

The digestive system is in charge of transforming the feed into assimilable nutrients, a key process in commercial poultry farming to maintain health status and obtain good productive results. It also works as a selective barrier to protect the organism from harmful agents. Any disease that affects the function of the digestive system will lead to a loss of productive performance, such as growth retardation, poorer conversion rates and feed efficiency, and even high mortality. As an...

Dietary energy available to animals is key to formulating feed as it is required for all aspects of animal life. In poultry, apparent (AME) and true (TME) metabolisable energy (ME) values have been developed for feed formulation with or without correction for nitrogen balance. Over the past 50 years, the accuracy of ME systems has been an ongoing debate and the data produced from different bioassays have been found not to be comparable (Farrell, 1999). Overall, the ingredient matrix ME...

Canola and camelina meals have been identified as alternative plant protein sources in place of soybean meal for animal feeding. The use of these protein sources at high inclusion levels is limited due to the presence of antinutritional factors such as phytic acid, glucosinolates, erucic acid, sinapines and tannins which have negative effects on production performance of broiler chickens (Thacker and Widyaratne, 2012). Solid state fermentation is a preferred method for enriching...

I. INTRODUCTION
The non-therapeutic use of antibiotics in animal feed has been banned in some regions of the world (Lekshmi et al. 2017) and there are restrictions on the use of some products in other countries, including Australia (APVMA, 2017). This has led to a search for alternatives to antibiotics for use in poultry production. Yeasts and their by-products have been identified as potential alternatives to antibiotics. In a recent study (Ahiwe et al., 2018),...

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.

The poster entitled “N-glycan profiling of chicken intestine as a tool for designing improved feed supplements” presented an...
