Abstract
The Poultry formers main problem with forming is the cost of the feed which is given to the birds. The feed cost is about 70% of the total expenditure. This is because the bird cannot produce the enzymes which can digest the polysaccharides present in the feed. These polysaccharides are very rich in feed. And so to avoid this problem of feeding high to bird we add supplements to the feed, i.e. NSP-Enzymes (Non-Starch Polysaccharides) these are the enzymes which a bird cannot produce. As we know that enzymes are Biocatalysts which enhance the reaction without undergoing any changes in them. They also enhance the growth of the bird and as the wastage feed decreases the effect of the bird dropping on environment also decreases. This review tells us that how the enzymes help the environment and the formers of poultry.
Highlights
The poultry feed contains Starch, proteins, fat and fibers [1]
Because of the ability of the nonstarch polysaccharide (NSP) enzymes which hydrolyze the components of cereals, a class of feed additive containing the NSP enzymes is mixed in the feed [3]
These enzymes help the bird to NSP components The intake of feed increases, the utilization of feed by the birds decrease and cost increases The food which is taken by bird is not digested and the intestinal viscosity increases Absorption of bile juices increases Microbial flora of intestine gets altered and its growth increases \
Summary
The poultry feed contains Starch, proteins, fat and fibers [1]. In these the main components present in the feed made of cereals are cellulose, 1-3,1-4-ß-glucans and pentosans of the arabinoxylan type [2]. Because of the ability of the NSP enzymes which hydrolyze the components of cereals, a class of feed additive containing the NSP enzymes is mixed in the feed [3]. From the day formers started using the feed enzymes mixture it has been observed that the growth of the bird has increased even more [4,5] These enzymes are compared to the probiotics available for humans [6]. It is found that individual enzymes are showing good It effects environment by high nitrogen and phosphorus exertion results than the cocktail of enzymes [9]
