摘要
为促进拉鲁湿地生态循环,增加西藏地区“非常规性饲料”,该研究选取6种菌剂和一种蜜糖,按照不同比例配成青贮发酵配方,探究不同配方对拉鲁湿地水生植物青贮饲料品质的影响。对拉鲁湿地水生植物青贮后的pH值和乳酸等发酵品质,以及青贮后的营养成分、微量元素、氨基酸和脂肪酸进行评定。研究结果表明:在该试验条件下,不同配方之间pH值无显著性差异,均在4.2以下,PF1组乳酸含量较高;各处理组之间初水分、干物质、可溶性蛋白占总蛋白比例、中性洗涤蛋白和过瘤胃蛋白占总蛋白比例无显著性差异,PF1组粗蛋白、粗灰分、水溶性碳水化合物、有效蛋白和单糖含量高于其他处理组,PF1组中性洗涤纤维、酸性洗涤纤维、木质素和淀粉含量低于其他处理组;PF9组钙和氯含量高于其他处理组,PF1和PF2组钾含量高于其他处理组,PF2组氮含量高于其他处理组。综合分析,拉鲁湿地水生植物使用PF1配方青贮处理效果最佳。
In order to promote the ecological cycle of the Lalu wetland and increase the"unconventional feed"in Tibet,six kinds of bacteria and one kind of molasses were selected and mixed into a silage fermentation formula according to different proportions to explore the effects of different formu⁃las on the quality of aquatic plant silage supplies in Lalu wetland in this study.The fermentation qualities,such as pH and lactic acid,as well as the nutrient content,trace elements,amino acids and fatty acids of silage from aquatic plants in the Lalu wetlands,were evaluated.The results showed that under the experimental conditions,there was no significant difference in pH value between different formulations,all of which were below 4.2,and the lactic acid content of the PF1 group was higher.There were no significant differences in initial moisture,dry matter,proportion of soluble protein to to⁃tal protein,neutral detergent protein,and the proportion of rumen protein to total protein between the treatment groups.Crude protein,crude ash,water-soluble carbohydrates,effective protein,and simple sugars were higher in the PF1 group than in the other treatment groups.Neutral detergent fi⁃ber,acid detergent fiber,lignin,and starch were lower in the PF1 group than in the other treatment groups.Calcium and chloride were higher in the PF9 group than in the other treatment groups.Potassium was higher in the PF1 and PF2 groups than in the other treatment groups and nitrogen was higher in the PF2 group than in the other treatment groups.In a comprehensive analysis,the PF1 formulation was the best silage treatment of aquatic plants in Lalu wetland.
