The basic nutrients that poultry birds require for maintenance, growth and reproduction include carbohydrates, proteins, minerals and vitamins. The energy and protein are the most important as well as expensive nutrients in poultry diet. Maize and soyabean meal are the conventional feed ingredients commonly used in poultry industry because of its nutrients composition and digestibility. In recent year skyrocketing prices of conventional protein sources like soyabean meal, has leads to increase in feed cost and production cost of chicken. Today's biggest challenge in poultry industry is optimising feed cost by using alternative non-conventional protein sources like DDGS, Maize Gluten, Rapeseed Meal, Groundnut Cake, Cotton Seed Cake, Guar Meal, Sunflower Meal, etc. There are some limitations in using such alternative ingredients due to poor nutrient digestibility and presence of anti-nutritional factors like non starch polysaccharides (NSP's), phytate and protease inhibitors. Anti-nutritional factors are inhibiting normal feed digestion, & thereby bird's health results to compromised performance.

NSPs shows anti-nutritive effect and inhibit the digestion and utilization of dietary nutrients by two mechanisms. First mechanism linked
the fact that nutrients are encapsulated by the fibrous cell wall so that digestive enzymes cannot reach there thus nutrients remains unutilised. Second mechanism relates the viscous nature of digesta caused by NSPs which directly affects passage rate of digesta and nutrients utilisation. Phytate blocks the absorption of not only phosphorus but also other minerals, particularly calcium, magnesium, iron, and zinc. Phytate also negatively affect the absorption of proteins and lipids. Poultry birds do not produce enzymes for the hydrolyses of NSPs and phytate, present in feed. Use of exogenous enzymes like protease, xylanase, mannanase, phytase, etc. gives flexibility in using alternative ingredients without compromising bird's performance by reducing anti-nutritional effects and improving nutrients availability.

PROMAXYL-α is a comprehensive solution designed through extensive research and substrate consideration over the lifetime of the birds. It is combination of Protease (Acid, Alkaline and neutral), endo 1,4-β- Xylanase, endo 1,4-βMannanase, α Amylase and 6 Phytase for more nutrient release. PROMAXYL-α targets the major anti-nutritional factors increases the digestibility and utilization of nutrients in poultry by improved utilization of phytate phosphorous, non-starch polysaccharides, starch, proteins and amino acids.
It gives flexibility for using non-conventional feed ingredients. It will provide up to 115 Kcal/ kg energy and 3 % protein of total CP present in feed. It enables producers to naturally enhance the growth of their birds, lower feed cost and maximize profits.
