摘要
试验选用9只健康的雄性卡拉库尔公羊为试验动物,采用全收粪消化试验方法,研究不同的小花棘豆添加量下卡拉库尔羊对青贮饲料的利用率。试验结果表明,小花棘豆添加量在400 g/d和800 g/d时,卡拉库尔羊干物质、粗蛋白、粗脂肪和矿物质采食量均有所提高,NDF和ADF采食量降低;卡拉库尔羊干物质、粗蛋白、粗脂肪、矿物质和ADF的消化率均显著增高,NDF消化率变化不显著。通过对试验羊AMA、AKP、BUN、GOT、GPT、LDH活性的监测,400 g/d和800 g/d的小花棘豆添加量对卡拉库尔羊的健康无明显影响。
Nine male health karakul rams was chosed in the experiment,The method of total collect feces was used to study the karakul rams＇ utilization of silage at different oxytropis glabra DC addition.The results showed that the karakul rams＇ appetite of DM、CP、EE and mineral matter was increased,when the amount of breeding for oxytropis glabra DC was 400 g/d and 800g/d,but the Karakul Rams＇ appetite of NDF and ADF was decreased.The karakul rams＇ digestion rate of NDF had no significantly difference indigestibility among three groups,but the digestion rate of DM、CP、EE、ADF and mineral matter was raised when affixed oxytropis glabra DC.Detect the activity of AMA、AKP、BUN、GOT、GPT and LDH from blood serum of karakul rams,the amount of breeding for oxytropis glabra DC was 400 g/d and 800 g/d had no harmful effects for karakul rams.
