摘要: 利用凯氏定氮法、索氏抽提法、高温炭化灼烧法、酸碱法、EDTA反滴定法、钼黄比色法对河北省唐山市迁西、遵化、迁安3市(县)采集的栗树叶样品的粗蛋白、粗脂肪、粗灰分、粗纤维、钙、总磷和无氮浸出物含量进行了测定,并与黑麦草、玉米秸秆和羊草的营养指标进行了分析比较,以研究栗树叶的饲料化利用价值。结果表明,遵化、迁安、迁西3市(县)栗树叶营养成分含量差异不显著,栗树叶中粗蛋白含量为10.81%、粗脂肪含量为5.44%、粗纤维含量为21.69%、粗灰分含量为9.86%、钙含量为1.82%、总磷含量为0.33%、无氮浸出物含量为52.20%。栗树叶的粗蛋白、粗脂肪、钙和总磷含量均高于黑麦草、玉米秸秆和羊草含量,而粗纤维含量低于黑麦草、玉米秸秆和羊草含量,因此其具有较高的饲料化利用价值。

Abstract: In order to study the nutritional and feeding value of chestnut leaves,the content of crude protein,crude fat,crude ash,crude fiber,calcium,total phosphorus,and nitrogen free extract in chestnut leaves collected from Qianxi,Zunhua and Qian′an regions of Tangshan of Hebei Province were determined by using Kjeldahl method,Soxhlet extractor method,high-temperature combustion method,acid-alkali degradation method,EDTA anti-titration method and molybdenum yellow colorimetric method.The nutritional value evaluating indicators of the chestnut leaves were statistically compared with those of Lolium perenne,corn stalk and Leymus chinensis.The results showed that there were no significant differences in the nutritional components content between the chestnut leaves collected from the three different regions;the average contents of crude protein,crude fat,crude fiber,crude ash,calcium,total phosphorus and nitrogen free extract in chestnut leaves were 10.81%,5.44%,21.69%,9.86%,1.82%,0.33%and 52.20%,respectively.The chestnut leaves had higher contents of crude protein,crude fat,calcium and total phosphorus as well as lower content of crude fiber compared to Lolium perenne,corn stalk and Leymus chinensis,indicating its high feeding value for livestock and poultry.
