摘要
This study aimed to evaluate the use of sodium monensina (Rumensin®) and yeast culture (Saccharomyces cerevisiae - Beef - sacc®) on concentration of short chain fatty acids (SCFA), ammonia and ruminal pH, and microbial efficiency in bubaline and bovine, fed diets with 50% concentrate. Three buffalos and three bovines whith cannulas on the rumen and duodenum were distributed in two Latin squares, with factorial arrangement 3 x 2. The concentrations of SCFA, ammonia and ruminal pH were determined every two hours. The flow of the digest and microbial protein on duodenum were determined from de utilization of insoluble ashes in acid and the utilization of purine bases as microbial indicator, respectively. The additives and species did not influence the total concentration of SCFA, acetic acids, propionic and butyric, but the addiction of yeast culture reduced the acetate/propionate ratio and the monensin reduced on a more effective and similar for the species, which were higher in the bubaline. The syntheses efficiency was higher in bovines, and reduced by the addiction of monensin. The yeast culture and monensin on ruminal fermentation changed in a positive way, and the cattle and buffaloes showed differences in the studied parameters

他的研究旨在评价单核细胞增多症（Rumensin）和酵母培养物（Saccharomyces cerevisiae-Beef-sacc / sup）对短链脂肪酸（SCFA）浓度的使用， ，氨和瘤胃pH，以及在具有50％25浓缩物的气泡和牛，进食日粮中的微生物效率三个水牛和三个牛只插管在瘤胃和十二指肠分布在两个拉丁方块，与因子安排3 x2 SCFA的浓度，氨和瘤胃pH每2小时测定通过酸中不溶性灰分的利用和嘌呤碱作为微生物指示剂的利用，测定十二指肠上的消化物和微生物蛋白的流动添加剂和种类不影响SCFA，乙酸，丙酸和丁酸的总浓度，但是酵母培养物的成瘾减少了乙酸盐/丙酸盐比率，并且莫能菌素对于物种更有效和更相似地减少，其在气泡中更高牛肉中的合成效率较高，并且通过莫能菌素的成瘾降低。酵母培养物和莫能菌素对瘤胃发酵以积极的方式改变，牛和水牛在所研究的参数中显示出差异
