摘要: 旨在研究不同处理方式对青贮稻秸秆发酵的影响和青贮稻秸秆对山羊生长性能和血液生化指标的影响。在稻秸中加入乳酸菌、纤维素酶和糖蜜进行混合青贮,结果发现:在稻秸秆中添加2.5 g/t 乳酸菌、600 g/t 纤维素酶、4%糖蜜和加水200 kg/t 进行混合青贮能够降低pH(P<0.01)、丁酸和丙酸浓度(P<0.05);显著提高干物质(P<0.01)、粗蛋白(P<0.05)和可溶性碳水化合物(P<0.01)含量,而粗脂肪、中性洗涤纤维和酸性洗涤纤维则相反。将青贮稻秸替代30%、60%和100%粗饲料进行饲喂山羊。结果显示:替代100%组羊的末重和平均日增重显著高于其他各组(P<0.01),料重比最低;各组的平均日采食量无显著差异。替代60%组山羊的血清碱性磷酸酶浓度(P<0.01)和总胆固醇含量(P<0.05)均显著降低。综上所述,稻秸秆中添加2.5 g/t 乳酸菌、600 g/t 纤维素酶、4%糖蜜和加水200 kg/t 进行混合青贮的效果较好,且青贮稻秸代替100%粗饲料能够提高山羊的生长性能,降低成本

Abstract: The study aims at the effects of different treatments on fermentation of ensiled rice straw and effects of ensiled rice straw on growth performance and blood biochemical indexes of goat. The ensiled rice straw with 2.5 g/t lactic acid bacteria, 600 g/t cellulase, 4% molasses and 200 kg/t water could reduce pH value (P < 0.01), concentrations of butyric acid and propionic acid (P <0.05), while increase the contents of dry matter (P <0.01), crude protein (P <0.05) and water soluble carbohydrate (P <0.01). However, the contents of crude fat, neutral detergent fiber and acid detergent fiber had the reverse results. The goats were fed with the diets, in which 30%, 60% and 100% roughage was replaced by ensiled rice straw, respectively. The results showed that the final body weight and average daily gain of goats in group of 100% roughage replaced by ensiled rice straw were significantly higher than those of other groups (P <0.01), but the feed to gain ratio was the lowest. Average daily feed intake showed no significant difference among the groups. Compared with those in the control group, the alkaline phosphatase concentration (P <0.01) and total cholesterol content (P <0.05) in serum of goats in group of 60% roughage replaced by ensiled rice straw decreased significantly. In conclusion, the ensiled effect of rice straw mixed with 2.5 g/t lactic acid bacteria, 600 g/t cellulose, 4% molasses, and 200 kg/t water was better. Replacing 100% roughage by ensiled rice straw could improve growth performance of goat, and reduce breeding cost.
