摘要

Abstract

The experiment aims to explore the feeding quality of straw from different rape varieties in Xizang.Using 10 common rape varieties grown in Xizang as experimental materials,eight nutritional indicators,including crude protein,crude fat,and crude fiber of the straw were determined.Correlation analysis,principal component analysis,and cluster analysis methods were employed to evaluate the nutritional quality of the straw.The results showed that there was a highly significant positive correlation between crude protein content and crude fat content in rape straw(P<0.0l),and a significant positive correlation between crude protein content and crude fiber content(P<0.05).Crude ash content showed a highly significant positive correlation with crude fiber content(P<0.0l),and neutral detergent fiber content showed a highly significant positive correlation with acid detergent fiber content(P<0.01).Acid detergent fiber content was negatively correlated with calcium content and phosphorus content(P<0.05).Phosphorus content and calcium content showed a highly significant positive correlation(P<0.01).The comprehensive score ranking of straw nutritional quality was as follows:Zangyou 3>104005>166052-1>Jinghua 165>Zangyou 5>Zangyou 12>Shanyou 2>Pengbohuang>Xiangyou 420>127025-1.The study indicates that high-quality rape varieties for straw in Xizang include Zangyou 3,104005,and 166052-1.The results can provide a reference for the utilization of rape straw as feed in Xizang.
