饲用双低油菜华协1号营养成分含量动态及营养价值研究

Studies on nutrient content dynamics and nutritive value of Huaxie 1 forage rape

对三种豆科饲草、谷草和双低饲用油菜华协1号进行的营养成分含量动态分析结果表明,饲用双低油菜粗纤维含量较低,粗脂肪含量较高,无氮浸出物和钙含量最高,粗蛋白质含量、有机物消化能和磷含量接近豆科饲草,各种营养成分极显著的(P<0.01)高于谷草,其化学营养类型与豆科饲草同属N型,是品质优良的饲草。

The nutrient content dynamics of three legume manure crops (Vicia villosa, Melilotus albus and Vicia sativa), millet grass (Setaria italica) and Huaxie 1 rape (Brassica napus) which contains low mustard acid and low sulfoglucoside were analyzed. The results indicated that the crude fiber content of Huaxie 1 rape was the lowest and the crude fat was the highest. The content of nitrogenfree extract and Ca in Huaxie 1 rape is the highest among determined forages.Its crude protein content, organic digestible energy and P content approached to those of legume forages. The content of each nutrition in Huaxie 1 rape was higher significantly than that of milletgrass (P<0.01). The chemical type of nutrition in Huaxie 1 rape is similar to legume and belongs to N type. It is a quality forage.
