Majority of broiler feed in India is usually composed of Corn and Soyabean meal (SBM) as a source of energy and protein, respectively. However, owing to increasing demand-supply gap, there has been a steep rise in the price of these ingredients in last two decades. Soya prices in India have almost tripled recently leading to a sharp reduction in profitability and lean margins for producers. A possible approach for the industry to overcome such crunch in profitably is the use of “non-conventional” feed ingredients which are essentially alternates to more costly corn and SBM. The whole premise of the usage of alternate raw materials (RM) in poultry feed is based on the inclusion of small quantity of such non-conventional ingredients which can be included as an alternate to more expensive ingredient but not negatively impacting growth and performance of the bird upon its dietary incorporation. This help producers to maintain feed quality at the same time reduce the feed cost.

 In order to completely make proper use of alternate raw materials and for efficient nutrient utilization in general, exogenous enzymes are vital tool. Inclusion of various exogenous enzymes improves access to the nutrients, which bird by itself is unable to utilize thereby improving the efficiency of nutrient utilization and cost savings. Phytase and cellulaseare two groups of enzymes that can be used in broiler diets with the aim of improving digestibility of unconventional feed ingredients.
