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.
研究了酶处理和未处理的珍珠粟复水对肉鸡利用的影响。将珍珠粟颗粒加水使其水分含量提高到 30%，然后在室温（25°C）下储存在密封的塑料桶中，添加或不添加饲料酶（0.5 g/kg）21 天。随后，将谷物晒干至水分含量降至 10%，以防止霉菌生长。设计了 9 种饮食处理方法，在以玉米-大豆为基础的对照饮食中，分别用生的或酶处理的或酶处理复水的珍珠粟代替 50%和 75%的玉米。以酶处理复水的珍珠粟为食的鸟类体重增加高于以玉米为基础的对照饮食。在生珍珠粟基础饮食中添加酶可显著提高体重增加。酶处理和未处理的珍珠粟复水均增加（P < 0.01）了饲料氮校正表观代谢能（AMEn）值，在以 75%玉米替代水平的酶处理复水珍珠粟日粮中，提高幅度最大（6.11%）。珍珠粟日粮的氮保留百分比与以玉米为基础的对照日粮相当。结论是，饲料酶的补充或珍珠粟的复水可能会提高肉鸡对珍珠粟的利用率。
