青贮香根草替代日粮中不同比例青贮菠萝渣对泰国生长沼泽性公水牛消化代谢、微生物蛋白产量、血液生化指标及生长指标的作用Vetiver Grass Silage alternative diets in different proportions of pineapple (Ananas comosus) waste silage on the growth of Thai swamp of male buffalo digestion and metabolism, microbial protein yield, blood biochemical index and growth index of impact in 摘要:（摘要内容经过系统自动伪原创处理以避免复制，下载原文正常，内容请直接查看目录。） 在亚洲西北部的很多国度，菠萝渣已被普遍用于反刍六畜包含肉牛和水牛纤维和动力饲料起源。但是，工业加工过的菠萝渣年夜小适中，能较快地穿过瘤胃，进而招致消化率很低。是以，本实验目标就是在40%菠萝渣60%混杂精料日粮基本上，用分歧比例喷鼻根草(0%， 10%， 20%和30%)来替换对应比例的菠萝渣组成4种分歧日粮日粮1(40%菠萝渣/60%混杂精料)，日粮2(10%喷鼻根草/30%菠萝渣/60%混杂精料)，日粮3(20%喷鼻根草/20%菠萝渣/60%混杂精料)，日粮4(30%喷鼻根草/10%菠萝渣/60%混杂精料)到达下降固体食糜在瘤胃中的流速，进而进步日粮消化率的目标。另外一目标是研究分歧日粮对泰国发展的池沼性公水牛自在采食量，微生物卵白产量，血液生化目标及发展目标的作用。实验成果以下1。干物资采食量跟着日粮中喷鼻根草含量的增长而增长，从天天3。33kg (0%喷鼻根草40%菠萝渣)增长到天天5。11kg(30%喷鼻根草10%菠萝渣)。异样，泰语专业论文，无机物资采食量从天天3。05kg(0%喷鼻根草40%菠萝渣)增长到天天4。65kg(30%喷鼻根草10%菠萝渣)。然则，中性洗濯纤维采食量在各个日粮间没有差别(1。10一1。24kg/d)。但是，干物资(0。81一0。55)，无机物资(0。84一0。49)和中性洗濯纤维(0。81一0。49)消化性跟着日粮中喷鼻根草比例的增长而下降，这招致了可消化干物资采食量(2。71一3。03kg/d)和可消化无机物资采食量(2。57一2。91kg/d)在各日粮间没有差别。2。固体食糜在瘤胃中流速(k1)在各日粮间没有明显分歧(1。89一2。62%h一1)，但是穿过盲肠和结肠的流速(k2)却跟着日粮中喷鼻根草含量的增长而加速，从每小时4。75%(0%喷鼻根草40%菠萝渣)增长到每小时6。68%(30%喷鼻根草10%菠萝渣)。依据下面参数，盘算出在胃肠道总的滞留时光(TMRT)跟着日粮中喷鼻根草比例的 Abstract: In many countries of Southeast Asia, pineapple residue has been commonly used for ruminant livestock including cattle and buffalo fiber and power feed origin. However, the industrial processing of pineapple residues in the eve of the small moderate, can quickly through the rumen, and thus lead to a very low rate of digestion. Slag of pineapple grass mixed slag of pineapple grass roots of hybrid pineapple slag slag of pineapple pineapple grass root basic slag of pineapple, so the goal is in 40% 60% mixed concentrate diets, with different proportion of nasal spray (0%, 10%, 20% and 30%) to replace the corresponding to the ratio of slag composed of 4 kinds of different diet diet 1 (40% and 60% mixed concentrate), diet 2 (10% nasal spray grass roots / 30% and 60% concentrate), diet 3 (20% nasal spray / 20% and 60% concentrate), diet 4 (30% nasal spray root / 10% and 60% mixed concentrate) arrive in the fall of solid digesta in the rumen of flow rate, and improve the diet digestibility. Another goal is to study different diets of Thailand swamp buffaloes free intake, microbial protein yield, blood biochemical target and development target. The results of the experiment are as follows 1. Feed intake of dry materials followed the growth of the root grass content of the diet, from day to day 3. 33kg (0% of the root grass 40% pineapple residue) rose to 5 per day. 11kg (30%, 10%). Also, the amount of inorganic material feed intake from day to day 3. 05kg (0% of the root grass 40% pineapple residue) rose to 4 per day. 65kg (30%, 10%). However, there is no difference between the intake of neutral washing fiber in the diet (between 1. 10 a 1. 24kg/d). However, dry materials (0. 81 A 0. 55), inorganic materials (0). 84 A 0. 49 (0) and neutral washing fiber. 81 A 0. (49) the digestibility of the diet decreased with the increase in the proportion of nasal spray in the diet, which resulted in the intake of digestible dry matter (2). 71 A 3. Food intake (2) and digestible inorganic materials (). 57 A 2. 91kg/d) there is no difference between the diets. 2. In the rumen solid digesta flow rate (K1) had no obvious differences in diet between (1. 89 A 2. 62%h (1), but the flow rate (K2) through the colon and the colon () was accelerated by the growth of the root grass in the diet. 75% (0% of the 40% pineapple residue) rose to 6 per hour. 68% (30%) of 10% pineapple residue. According to the following parameters, calculate the total retention time in the gastrointestinal tract (TMRT) followed by the proportion of the diet in the nasal spray 目录: |
