摘要
对云南省反刍家畜主要生产基地所属九个县(市)812个反刍家畜常见饲料样品的13种矿质元素及常规营养成分进行测定分析,并进行不同层次的相关分析,结果表明:镁、磷、铁、钙、钴和铜与饲料常规营养成分相关性最大,其次为硒、钾、锰等,它们与多数饲料的粗蛋白、粗脂肪、灰分呈正相关;与粗饲料的粗纤维呈负相关;对新有饲料钙、镁、钾都与无氮浸出物呈负相关。
The present studies determine the thirteen elements and proximate nutrients of forages. The results show that there are higher correlation coefficient between manage, phorophas, iron, calcium, cobalt, copper and proximate nutrients of feed than selenium, potassium and manganese, which have positive correlations with crude protein, ether extract and crude ash, negative correlation with crude fibre. The correlations coefficients are negative between calcium, manganese, potassium and non-nitrogen extract .
