Three experiments were conducted to determine the nitrogen-corrected metabolizable energy (MEn) content of ground pearl millet [Pennisetum americanum (L.) Leeke]. On a dry matter basis, 40% ground pearl millet was substituted for an equivalent amount of glucose monohydrate (reference substance) to determine MEn using male broiler chicks. Food and excreta samples were analyzed for nitrogen, gross energy, chromic oxide, and dry matter. On a dry matter basis, the MEn content of the ground pearl millet ranged from 2.891 to 3.204 kcal/g, depending upon the pearl millet cultivar used. These results suggest that previously reported MEn values for pearl millet may be underestimated by up to 21%.
进行了三项试验以测定去壳珍珠粟[美洲狼尾草(L.)利克]的氮校正代谢能(MEn)含量。以干物质为基础,用40%的去壳珍珠粟替代等量的一水葡萄糖(参考物质),使用雄性肉鸡来测定MEn。对食物和排泄物样本进行氮、总能、氧化铬和干物质分析。以干物质为基础,去壳珍珠粟的MEn含量在2.891至3.204千卡/克之间,这取决于所使用的珍珠粟品种。这些结果表明,先前报道的珍珠粟MEn值可能被低估了高达21%。
