摘要： 由于大部分养殖户或养殖场对杨树叶和松针可以作为饲料原料来合理利用的了解甚少,以致于我市杨树及松针资源在饲料行业上的应用还不是很广泛。本文通过对榆阳区西北风沙区2007年的4、7、9、10月份(即大体上是植物从生长初期到落叶期)的杨树叶和松针的主要营养成分进行测定,并对比分析,结果表明两样本的粗纤维随生长的进行均呈明显上升趋势,而粗蛋白则均呈明显下降趋势,但粗脂肪、粗灰分、钙、磷、有机物、无氮浸出物等成分均无明显规律性. 同时,杨树叶在生长的过程中粗蛋白、粗纤维含量变化趋势明显,而松针的则变化相对平稳。通过本文的研究可以为我市开发杨树和松针资源作为饲料原料来利用提供一些有用的数据,并就杨树叶和松针做为我市节粮饲料原料的利用方法上提一些建议,供参考。

Abstract: Culturists and farms understand few about rational utilization of poplar leaves and pine needles as feedstuff, whose utilization in feed industry is not sufficient. The authors analyzed main nutritional component of poplar leaves and pine needles in April, July, September and October (early growth stage to leaf fall period) in 2007 in sandstorm area in Yulin. The results showed that the crude fiber content increased obviously with the growth, while crude protein content decreased, and the changes in crude fat, crude ash, calcium, phosphorus, organic matter, nitrogen-free extract and other compositions had no obvious regularity. In the same time, the change of crude fiber and crude protein of poplar leaves was obvious, while that of pine needles was steady. The results could provide data for the utilization of poplar leaves and pine needles as feedstuff, and references for their utilization.
