沙打旺饲喂小尾寒羊试验

以小尾寒羊为试验动物,分别以沙打旺Astragalus adsurgens干草、青干草、沙打旺干草(50%) 青干草(50%)为全期日粮做饲养对比试验.对体增重、耗草量、饲料报酬等指标进行测定,并通过屠宰试验对血液和内脏器官表观性状做比较分析.结果表明:沙打旺组试羊日增重极显著优于青干草组(P<0.01).试羊单位体重的增加沙打旺组比青干草组少消耗草39.58%,50%沙打旺组比青干草组少消耗饲草18.91%,沙打旺干草饲用价值明显优于青干草.屠宰剖检试验表明,各试验组屠宰指标差异不大,肉质及血液内脏器官都表现正常,无明显差异.

Study on small-tailed sheep fed with Astragalus adsurgens hay as whole diets

Three groups contrast experiments were conducted by taking Astragalus adsurgens hay,green hay,half hay plus half green hay as diets respectively and small-tailed sheep as the experimental animal.The increase of the weight,quantity in consuming hay and compensation of feed were determined;and then blood and internal organs apparent condition were analyzed with slaughter experiments.The result showed that the daily increase in the weight of the group fed with A.adsurgens hay is significantly higher than that of the group fed with green hay(P<0.01).As the unit weight increase of tested sheep,the hay consuming in the group with A.adsurgens is 39.58% less than that of the group fed with green hay,the group fed with half A.adsurgens 18.91% less than that of the group fed with the green hay.The feed value of A.adsurgens hay is higher than that of green hay significantly.The slaughter experiment represented that there is little difference in every group.There is no significant difference and abnormity in the quality of meat,blood and internal organs among the three groups.
