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 approach of supplementing poultry feed with a combination of xylanase and direct-fed-microbials (DFMs), along with other management practices, to improve gut health is gaining increased attention as feed-additive alternatives to replace growth promoting antibiotics (AGP).
The objective of this study was to evaluate the efficacy of various combinations of different endo-xylanases and multi-strain Bacillus spp. products from different commercial sources upon...

For the last three decades poultry production worldwide has made tremendous progress in terms of quantity and quality of meat and egg production, including improvement of growth rate and feed conversion rate. However, it has been proven that commercial poultry production is associated with a range of stresses including environmental, technological, nutritional, and internal/biological [1,2]. Indeed, it is practically impossible to avoid stresses, so therefore overproduction of free radicals...

When it comes to poultry feed, particle size makes a big difference for bird nutrition.
Research shows that chickens increase their feed intake and performance when given pelleted feed or crumbled pellets, compared with mash.
This has led researchers to wonder whether feeding crumbles could jumpstart very early chick growth and boost final broiler body weights. It is important to study this question because pellets and crumbles are more...

As demand for goose products increases, poultry scientists and producers are working to combat bird mortality. One goal is to help geese fight infections without overusing antibiotics.
In a new study, published The Journal of Applied Poultry Research, poultry scientists explore the use of dietary yeast culture (YC) supplementation as a strategy to boost goose health while also improving meat quality.
Yeast culture is a dried prebiotic...

Introduction Use of the antibiotics in feed has shown several side effects like resistance towards the drug, residue in the meat and thereby the user getting resistance to the drug etc. hence several countries have banned the use of antibiotic based growth promoters in the feed animal sector and appearance of resistant strains in human beings. Alternative plant extracts and essential oils have been known to be used for many kinds of diseases by Egyptians, Chinese, Indians and...

I. INTRODUCTION The most important cost component of broiler feed relates to energy, as this may account for up to 75% of feed costs (van der Klis & Kwakernaak, 2008). Therefore, more accurate evaluation of feed energy in broiler production is imperative for environmental and financial reasons. The metabolisable energy (ME) system is currently the preferred measure for determining energy utilisation in poultry feed. However, this system does not give a complete picture of...

I. INTRODUCTION Soybean meal is the most widely used protein source in poultry diets, because of its high levels of crude protein, high digestibility and consistency compared to other protein ingredients. However, its nutritional value is affected by several factors, such as genetic selection (Palacios et al., 2004; Loeffler et al., 2013), production or planting environment (van Kempen et al., 2002; Goldflus et al., 2006) and crushing process, which affect the concentration of...

I. INTRODUCTION Growing emphasis on environmental regulation requires global animal production to adopt strategies like feeding low CP diets to minimize nitrogen excretion. However, in some of the animal feeding studies, lowering dietary CP beyond a certain level showed undesirable effects on growth performance and carcass quality of broilers. A number of explanatory approaches is being debated as the possible reasons for the consequences of lowering dietary CP on broiler...

I. INTRODUCTION Crude protein-reduced broiler diets have the potential to provide tangible advantages in respect of economics, bird welfare, flock health and the environment. Moderate reductions in dietary crude protein (CP) levels can be achieved without compromising broiler performance when coupled with judicious synthetic amino acid inclusions. However, there appears to be a threshold where further CP reductions negatively influence performance, especially FCR and this is...
