| 摘 要： | 为研究小麦(Triticum aestivum)秸秆型及玉米(Zea mays)秸秆型全价颗粒饲料作为家畜草料空缺期的应急料,在高寒牧区特殊气候条件下对甘肃高山细毛羊育成羊生长发育的影响,本研究选择体况相近的6月龄甘肃高山细毛羊育成母羊48只,随机分为试验组Ⅰ(18只,每只仅饲喂小麦秸秆型全价颗粒饲料1.2 kg·d^-1)、试验组Ⅱ(17只,每只仅饲喂玉米秸秆型全价颗粒饲料1.2 kg·d^-1)、对照组13只,每只饲喂玉米0.05 kg·d^-1+燕麦草(Avena sativa)0.2 kg·d^-1],在舍饲条件下进行为期16 d的饲喂试验。结果表明:试验组Ⅱ羊只平均日增重显著高于对照组(P<0.05);试验组Ⅱ羊只血清中总蛋白、球蛋白的浓度显著高于对照组(P<0.05);试验组Ⅰ羊只血清中谷草转氨酶、乳酸脱氢酶的活性及白蛋白的浓度显著高于对照组(P<0.05),试验组Ⅱ与对照组无显著差异(P>0.05)。由此可见,用玉米秸秆型全价颗粒饲料作为应急料优于传统的燕麦草与整粒玉米,能够充分满足甘肃高山细毛育成母羊在肃南高寒牧区饲草料空缺期和不足期生长发育中的营养需要。

| Abstract: | This study investigated the effects on Gansu alpine fine-wool sheep when they were fed wheat straw type and corn straw type full-price granular feed as emergency feed during the livestock forage vacancy period.These feeds may affect the growth and development of the sheep when they are growing under the special climatic conditions found in alpine pastures.We selected 48 six-month-old growing Gansu alpine fine-wool sheep with similar body conditions.They were randomly divided into two experimental groups.These were experimental groupⅠ(18 sheep,only fed wheat straw type full-price granular feed)and experimental groupⅡ(17 sheep,only fed corn straw type full-price granular feed).Each sheep was fed 1.2 kg of feed per day in the two test groups.There was also a control group(13 sheep)where the sheep were fed oat grass and corn(Each sheep was fed 0.05 kg corn and 0.2 kg oat grass per day).The feeding trials lasted 16 days under housefeeding conditions.The results showed that the average daily test groupⅡweight gain was significantly higher than the weight gain recorded in the control group(P<0.05).The total protein and globulin concentrations in the serum from test groupⅡwere also significantly higher than in the control group serum(P<0.05).The aspartate aminotransferase and lactate dehydrogenase activities,and the albumin concentration in the serum from test groupⅠwere significantly higher than in the control group serum(P<0.05),but there were no differences between the test groupⅡand the control group(P>0.05).The results showed using corn straw type full-price granular feed as the emergency feed produced better results than the traditional oat grass and whole-grain corn feed.The results also showed that the corn straw full price feed fully satisfied the nutritional needs of growing Gansu alpine fine-wool ewes during the growth and development period in the alpine pastures areas of Sunan,especially when there were forage vacancies and insufficiency periods. |
