ABSTRACT

This study investigated the effect of commercial probiotic supplementation in diet on apparent digestibility of forage fibre fractions, namely acid detergent fibre (ADF), neutral detergent fibre (NDF), cellulose, and hemicellulose in Indonesian thin-tailed rams. Twenty Indonesian local rams (22 ± 0.7 kg of live weight) were randomly assigned to four dietary treatments. The treatments were the percentage of probiotic supplementation on basal diet: PP0 (control/basal diet with no probiotic supplementation); PP025 (basal diet with 0.25% probiotic); PP050 (basal diet with 0.50% probiotic); PP075 (basal diet with 0.75% probiotic). The calculated amount of probiotic is then mixed to the basal diet prior to supplying to the animals. Rams fed diet with 0.50% and 0.75% probiotic supplementation had higher ADF, NDF, and cellulose digestibility compared with other treatments. In conclusion, the supplementation 0.50% probiotic in the diet is beneficial to enhance forage fibre digestibility in rams without giving any negative effect on performance.

摘要

这项研究调查了在日粮中添加商业益生菌对饲草纤维级分的表观消化率的影响，这些饲草纤维级分是印尼细尾公羊的酸性洗涤剂纤维（ADF），中性洗涤剂纤维（NDF），纤维素和半纤维素。随机将二十只印尼本地公羊（22±0.7公斤活重）随机分配给四种饮食疗法。治疗方法是基础饮食中补充益生菌的百分比：PP0（对照组/基础饮食中不添加益生菌）；PP025（0.25％益生菌的基础饮食）; PP050（含0.50％益生菌的基础饮食）; PP075（含0.75％益生菌的基础饮食）。然后，在将计算出的益生菌量提供给动物之前，先将其与基础饮食混合。饲喂0.50％和0.75％益生菌补充剂的公羊的ADF，NDF，与其他处理方法相比，纤维素的消化率更高。总之，在日粮中添加0.50％的益生菌有利于提高公羊的饲用纤维消化​​率，而不会对生产性能产生任何负面影响。
