【摘要】：本试验旨在研究芦笋茎叶青贮料日粮对生长湖羊生产性能、瘤胃发酵参数和血液生化指标的影响。选取36只体重为(19.46±2.07)kg的湖羊,根据体重相近原则,采用配对设计分为2组,对照组和试验组分别饲喂花生藤日粮和芦笋茎叶青贮料日粮,2组日粮的能量和粗蛋白等营养水平基本一致。试验期60 d,其中预试期7 d,试验始末称重,并进行消化代谢试验、采集血液和瘤胃液。结果表明:与对照组相比,芦笋茎叶青贮料对湖羊的平均日增重、相对增长、耗料增重比无显著影响(P0.05),但因芦笋茎叶廉价,平均每千克增重的饲料成本降低了1.8元,提高了湖羊养殖效益;与对照组相比,试验组日粮显著降低了湖羊瘤胃内乙酸含量和乙酸/丙酸(P0.05),对微生物蛋白、氨态氮、丙酸和丁酸均无显著影响(P0.05);同时试验组显著降低了血浆白蛋白浓度(P0.05),对总蛋白、球蛋白、葡萄糖、总胆固醇、甘油三酯、游离脂肪酸、总胆红素、肌酐、谷丙转氨酶、谷草转氨酶和超氧化物歧化酶等血液生化指标无显著影响(P0.05)。综上可知,芦笋茎叶青贮料日粮对湖羊生产性能无不良影响,因价格优势,增加了企业的经济效益,具有较好的应用前景。
[Abstract]:The purpose of this study was to study the effects of asparagus stalk and leaf silage diet on growth performance, rumen fermentation parameters and blood biochemical indexes of growing Hu sheep. Thirty-six Hu sheep with body weight of 19.46 卤2.07)kg were divided into two groups according to the principle of similar body weight. The nutritional levels of energy and crude protein were the same in the control group and the experimental group, which were fed with peanut vine diet and asparagus stalk and leaf silage diet respectively, the experimental period was 60 days, and the pretest period was 7 days, the weight was weighed at the beginning and the end of the experiment, and the digestion and metabolism tests were carried out. Blood and rumen fluid were collected. The results showed that compared with the control group, asparagus stalk and leaf silage had no significant effect on the average daily gain, relative increase, and feed consumption gain ratio of Hu sheep, but the asparagus stems and leaves were cheap. Compared with the control group, the feed cost of the experiment group decreased significantly the acetic acid content in rumen and acetic acid / propionate P0.05N, and the feed cost per kilogram increased by 1.8 yuan, and the effect of the diet on microbial protein and ammonia nitrogen was significantly decreased, compared with the control group, the diet of the experimental group significantly decreased the rumen acetic acid content and acetic acid / propionate P0.05N. Propionic acid and butyric acid had no significant effect on P0.05N, while the plasma albumin concentration was significantly decreased in the test group, and the total protein, globulin, glucose, total cholesterol, triglyceride, free fatty acid, total bilirubin, creatinine, alanine transaminase were significantly decreased in the test group. The blood biochemical indexes such as aspartate aminotransferase and superoxide dismutase had no significant effect on the production performance of Hu sheep. It has good application prospect.
