Modern-day intensive poultry manufacturing has been attaining phenomenal gains across economical and efficient production of the safe and high quality poultry bio-products, eggs and chicken meat. Feed additives are significantly essential in poultry sector for the purpose of improving the effectiveness of bird’s laying capacity as well as overall growth, for improving feed utilization and to prevent diseases. Commonly used feed additives in poultry diets are inclusive of pH control enzymes and agents, binders, emulsifiers, antioxidants and antimicrobials.
Antimicrobials are extensively utilized in the intensive poultry operations for the purpose of minimizing diseases, thereby improving feed utilization and growth. Poultry industry has been currently focusing on alternatives to the chemical therapeutics. In every case, it would be essential to minimize the challenges with regards to diseases, strengthen the natural defenses of birds and optimize the diet for providing a balance of essential nutrients for the changing needs of birds. All these factors is likely to increase the usage of feed additives across the poultry sector, thereby impacting the growth of animal feed additives market. Substitutes to the in-feed antibiotics primarily includes feed enzymes, immune-modulators, herbal products, prebiotics, probiotics and acidifiers.
Enzymes are the proteins, which helps in facilitating specific chemical reactions. Enzymes which are harvested through microbial fermentation as well as is added to the feeds, can help in breaking the bonds amid sugar units of non-starch polysaccharides (NSP) and significantly decrease gut content viscosity. The notable point is that lower viscosity leads to improved digestion, thereby improving absorption level as well.
Commercial feed enzymes reduces the side-effects of phytates. Researchers are taking immense efforts in developing more effective enzymes for maintaining the function under wide-ranging digestive and processing conditions. New feed enzymes have been developed in a way that it helps in reducing toxins that are produced during the feed spoilage as well as facilitates digestion of carbohydrates. These new animal feed additives are increasingly adopted in the poultry sector, thereby facilitating development of substantial new technology for advancing the usage and availability of the in-feed enzymes.
A range of reactive oxygen species sources are available in the normal metabolism, which also comes directly from the feed ingredients. Antioxidants helps in binding these molecules as well as reduces their potential damage.
Feed acidifiers help in lowering pH of feed and subsequently the gut environment as well. Acidifiers are present in both inorganic and organic acids and as associated salts as well. They can use their antimicrobial action for both feed as well as throughout the gut.
Probiotics are regarded as live mixed or mono culture of the microorganisms that are non-pathogenic, resilient to bile and gastric acids. After being ingested can lead to beneficial effects in the host animal, as it improves characteristics of the intestinal microbiota. Probiotics create environments in the intestine that favors valuable bacteria as well as inhibits development of the pathogenic bacteria.
Prebiotics are regarded as the indigestible food ingredients that fuel the activity and growth of certain number of bacteria’s in gastrointestinal tract of the host animal. Prebiotics enters the gut by serving as substrate for endogenous valuable bacteria, thereby promoting competitive prohibition of the pathogenic microbes as well as selective colonization by the beneficial microbes.
Most of the feed additives are regarded as usual part of diets for animals. But growing awareness has been stimulating efficiency and production, maintaining well-being and health, improving product safety and quality as well as reducing the impact of industry on environment. In a nutshell, animal feed additives are likely to play a vital role in preserving health of the poultry in an age of no pharmaceuticals.
