本研究旨在评价益生菌THAX和酸奶(作为益生菌)对肉鸡的生长反应和肠道菌群结果的影响。将240日龄罗斯308肉鸡平均分成12个地坪，饲养42日龄。试验包括酸奶(发育期、成熟期和育肥期分别为10%、5%和2.5%)和乳酸量(发育期、成熟期和育肥期分别为1000、500、250g/吨(-1))，共设3个试验组和一个对照组。在饲养初期，每组随机饲喂4个重复组，每组20只。分别在第21天和第42天称重禽类和饲料。试验结果表明，日粮中添加饲料添加剂能提高肉鸡的生产性能。体重增加和饲料转化率显著提高(p<0.05)。
The present study aimed at evaluating the effect of the probiotic thepax and yogurt (as probiotic) on the growth response and intestinal microflora results of broiler chickens. Two hundred forty day-old Ross 308 broilers were equally distributed into 12 floor pens and reared for 42 day. The treatments consisted of yogurt (10, 5 and 2.5% during starter, grower and finisher periods in the drinking water, respectively) and thepax (1000, 500, 250 g/ton(-1) in the starter, grower and finisher diets, respectively), resulting three experimental diets and a control group. Each dietary treatment was fed ad-libitum to four replicate group of 20 birds at the beginning of rearing period. Birds and feed were weighed on days 21 and 42. The results of experiment indicate that diets containing feed additives improved broiler performance. The body weight gain and feed conversion ratio improved significantly more (p
