Comparative study on production performance and nutritional value of two kinds of leguminous forages
In order to enrich the high-quality leguminous forage germplasm resources in Yunnan grass field rotation,the production performance and nutritional value of Ornithopus compressus were evaluated.The results showed that the Yellow serradella(Ornithopus com-pressus L.)had good adaptability in the temperate region of Yunnan,the yield of fresh grass was 15525kg/hm2,and the yield of hay was 7091.5kg/hm2,both of which were higher than Vicia villosa,especially the latter was higher than that of dry-fresh ratio up27.8%.In terms of nutritional composition,crude protein content of Vicia villosa was 17.43%,which was 3.09%higher than that of the Yellow serra-della(P<0.05),and P content of the Yellow serradella was 0.25%,which was significantly higher than that of Vicia villosa(P<0.05).The crude fiber content of the Yellow serradella was38.39%,which was higher than that of Vicia villosa,but the difference was not significant.Comprehensive analysis of nutrient composition showed that the nutritive value of the Yellow serradella was higher than that of Vicia villosa,which is widely used at present.
