不同类型玉米品种饲用营养价值比较

Forage Nutritive Value of Different Type Maize Cultivars

对粮饲兼用玉米鲁单 5 0 (LD5 0 )、高油玉米高油 115 (HO115 )和青饲玉米科多 4号 (KD4 )进行比较研究表明 :KD4的鲜、干物质产量最高 ,较LD5 0高 10 0 %、72 2 % ,粗蛋白和粗纤维的产量也最高 ,较LD5 0高 80 %、14 9% ;HO115的粗脂肪产量最高 ,较LD5 0高 6 2 % ,粗蛋白的产量也较高 ;LD5 0的籽粒产量显著高于KD4 ,但粗蛋白、粗脂肪和粗纤维的产量都最低。不同类型玉米品种饲用营养价值的差异主要是由于其生物学特性的显著性差异所致。

There were different forage nutritive value of the three maize cultivars, Ludan 50(LD50), Gaoyou 115(HO115), and Keduo 4(KD4) KD4 was the highest in fresh matter,dry matter,crude protein and crude fiber yield HO115 was the highest in ether extract yield, and also higher than LD50 in crude protein yield LD50 was the highest in grains yield, but the lowest in crude protein, crude fiber and ether extract yield The difference in forage nutritive value of different type maize was based on their different biologic characteristics
