摘要
The objectives of this study was to evaluate the influence supplementation levels of Yeast-Malate Fermented Cassava Pulp (YMFCP) replace soybean meal in concentrate on feed-intake, Average Dairy Gain (ADG), rumen ecology and blood metabolites in crossbred native cattle. Five, two years of female crossbred native cattles weighing at 250±10 kg were randomly assigned according to a 5 x 5 Latin square design. The dietary treatments were as follows: T1 = supplementation of YMFCP replace soybean ratio at 0:100%; T2 = supplementation of YMFCP replace soybean ratio at 25:75%; T3 = supplementation of YMFCP replace soybean ratio at 50:50%; T4 = supplementation of YMFCP replace soybean ratio at 75:25%, T5 = supplementation of YMFCP replace soybean ratio at 100:0%, respectively. The cows were offered the treatment concentrate at 1.0%BW. All cows were fed ad libitum of rice straw with water and a mineral salt block. The results have revealed that rumen fermentation, blood metabolites and average daily gain were significantly different for all treatments. The populations of protozoa and fungal zoospores were significantly different as affected by supplementation levels of Yeast-Malate Fermented Cassava Pulp (YMFCP) replace soybean meal in concentrate. Moreover, supplementation levels of Yeast-Malate Fermented Cassava Pulp (YMFCP) replace soybean meal ratio at 50:50% in concentrate with rice straw as roughage source could highest improved ruminal fermentation efficiency, average daily gain including increase populations of bacteria and fungi zoospores, but decreased protozoal populations in rumen of crossbred native cattle.

本研究的目的是评估酵母-苹果酸发酵木薯浆（YMFCP）替代浓缩饲料中豆粕对饲料-摄入量，平均乳业增重（ADG），瘤胃生态和杂交牛的血液代谢的影响。根据5 x 5拉丁方形设计，随机分配5、2年重达250±10 kg的雌性杂交牛。饮食处理如下：T1 =补充YMFCP替代大豆比例为0：100％； T2 =补充YMFCP替代大豆比例为25：75％； T3 =以YMFCP替代大豆的比例为50：50％； T4 =补充YMFCP替代大豆比例为75：25％，T5 =补充YMFCP替代大豆比例为100：0％。给母牛提供1.0％体重的治疗浓缩物。所有奶牛自由饮水和矿物盐块喂入稻草。结果表明，所有处理的瘤胃发酵，血液代谢产物和平均日增重均显着不同。酵母的添加水平对原生动物和真菌游动孢子种群的影响显着不同。苹果酸发酵木薯浆（YMFCP）代替浓缩豆粕。此外，以稻草为粗饲料的酵母-苹果酸发酵木薯纸浆（YMFCP）替代浓缩度为50：50％的豆粕比例可以最大地提高瘤胃发酵效率，平均日增重包括增加细菌和真菌游动孢子的数量，但杂种原生牛瘤胃的原生动物种群减少。
