摘要
2016年1—6月,从黑龙江、吉林、辽宁、河北、宁夏及山东等地区采集玉米青贮样本125份,采用湿化学方法测定不同地区玉米青贮的水分、CP、EE、ADF、NDF、Ash和淀粉含量,了解不同地区玉米青贮的品质,并与2015年玉米青贮品质进行比较。结果表明:2016年上半年玉米青贮品质略优于2015年;2016年上半年仍以西北地区青贮品质最优,东北和华北地区在各个营养指标上变异程度进一步增大。
January to June, 2016, the R ＆ D Center collected 125 samples of corn silage from Heilongjiang, Jilin, Liaoning, Hebei, Ningxia, Shandong, etc. Determination of moisture, crude protein, crude fat, neutral detergent fiber, acid detergent fiber, ash, starch of corn silage using wet chemical methods. Which can understand the quality corn silage in different regions,and also make a comparison with 2015. The results showed that the quality of corn silage in the first half of 2016 slightly better than the 2015. The Northeast is still the best the other area. There is a further increase the degree of variation in various nutrition indicators.
