近年来,世界各国更加强调牧草饲料营养价值评定的重要性。因为营养价值的评定是进行经济饲养的桥梁。只有了解牧草的营养价值才能预测家畜的生产性能,进而有效的、经济的发展草地畜牧业生产。营养成份是评定牧草饲用价值的重要指标之一。通过5年的草场资源调查,共采集新疆野生牧草达500余种。草场中的优势牧草种主要有禾本科、豆科、藜科、菊科、蓼科和沙草科等。最近几年我们配合自治区草 In recent years, countries all over the world have placed greater emphasis on the importance of assessing the nutritional value of pasturage and fodder. Because the assessment of nutritional value is a bridge for economic rearing. Only by understanding the nutritional value of pasture can we predict the performance of livestock and thus develop the livestock husbandry effectively and economically. Nutritional ingredients is one of the important indicators to assess forage value. Through five years of grassland resources survey, a total of more than 500 species of wild forage in Xinjiang were collected. The advantages of grassland forage species are mainly grass, legume, Chenopodiaceae, Compositae, Polygonaceae and sand grass family. In recent years we cooperate with the autonomous region grass
