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.
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...

Yeast cell wall (YCW) fractions have proven effective in reducing the incidence of necrotic enteritis induced by Clostridium perfringens. Dietary supplementation with YCWs stimulates the systemic innate immune responses of broiler chickens, suggesting the role of these products in regulating immune homeostasis (Alizadeh et al., 2016). In a proposed mode of action of YCW on bacteria, the branched lateral chains of the mannan-oligosaccharides (MOS) in the YCW structure bind the bacteria and...

1. Introduction Commercial poultry production is associated with a variety of environmental, technological, nutritional and biological/internal stressors which are responsible for decreased productive and reproductive performance and compromised health [1,2]. A great body of recent information clearly indicates that very often overproduction of free radicals, compromised antioxidant defences and oxidative stress are the leading causes of the detrimental consequences of...

I. INTRODUCTION Food waste refers to “the discarding or alternative (non-food) use of food that was fit for human consumption - by choice or after the food has been left to spoil or expire as a result of negligence” (FAO, 2015). It is estimated that the global economic loss caused by food waste is US$ 1 trillion annually. The wasted amount of cereals, root crops, fruits and vegetables, fish, oilseeds, meat and dairy products in the food industry has been estimated to...

Introduction The usage of antibiotics as a growth promoter is widely banned by European Union-wide in 2006 due to their side effects on animal health and their residues in meat for human health (EU-wide, 2005).

Necrotic enteritis (NE) is one of the most important diseases of the world broiler industry which costs over six billion dollars annually. There has been a concerted effort to control and minimise the effects of NE that have arisen since the EU ban of in-feed antibiotics in the poultry industry. Organic acids have been used as alternatives to in-feed antibiotics for maintaining good gut health of poultry by suppressing the growth of pathogenic bacteria, resulting in improved performance...
