Effect of high moisture storage of pearl millet (Pennisetum typhoides) with or without feed enzymes on growth and nutrient utilization in broiler chickens.
Effect of reconstitution of pearl millet with or without enzymes on its utilization in broiler chickens was studied. The pearl millet grains were reconstituted by adding water to raise the moisture level to 30%, followed by storage in sealed plastic buckets with or without feed enzymes (0.5 g/kg) for 21 days at room temperature (25 degrees C). Subsequently, the grains were sun-dried to reduce the moisture content up to 10% to avoid mould growth. Nine dietary treatments were formulated incorporating pearl millet either raw with or without enzymes or reconstituted with or without enzymes in maize-soya based control diet replacing maize at 50 and 75% levels. The birds fed on diets containing enzyme reconstituted pearl millet accrued higher body weight than maize based control diet. Addition of enzymes to raw pearl-millet based diet improved the body weight gain significantly. The reconstitution of pearl millet with or without enzymes increased (P < 0.01) the dietary nitrogen corrected apparent metabolizable energy (AMEn) values and the highest improvement (6.11%) was recorded in diets containing pearl millet reconstituted with enzymes at 75% level of maize replacement. The percent nitrogen retention in pearl millet based diets was comparable to maize based control diet. It may be concluded that the supplementation of the feed enzymes or reconstitution of pearl millet may improve the utilization of pearl millet in broiler chickens.
