The aim of the trial was to evaluate the influence of diet supplementation with Saccharomyces cerevisiae on nutrient digestibility and milk and mozzarella cheese yield in buffalo cows during the transition period. Twenty buffalo cows in the last month of pregnancy were equally divided into two groups (control, C, and treated, T) homogeneous for parity and milk yield at the previous lactation. The diet of group T was supplemented with 100 g/head/day of a product containing Saccharomyces cerevisiae (Sc 47- CNCM I-4407) for 4 weeks before and after calving. Dry matter intake and the body condition score were not affected by the dietary treatment. In contrast, organic matter, protein, NDF, and ADF digestibility significantly ( < 0.01) increased. Group T showed a higher milk yield (kg 10.5 vs. 9.2, < 0.05) but lower milk fat (g/kg 76.0 vs. 80.1, < 0.05). The buffalo standard milk (FPCM = 740 kcal) yield was higher in the treated group (kg 16.8 vs. 15.0, < 0.05), whereas the mozzarella cheese yield was not affected by the treatment ( > 0.05). These findings indicate that supplementation of the diet of buffaloes with Saccharomyces cerevisiae during the transition period results in notable enhancements in nutrient digestibility and milk yield. These outcomes are worthy of further investigation.
该试验的目的是评估在过渡期给水牛补充酿酒酵母对营养物质消化率以及牛奶和马苏里拉奶酪产量的影响。将20头处于怀孕最后一个月的水牛平均分为两组（对照组，C组；处理组，T组），两组在前一胎次的胎次和产奶量方面保持一致。在产犊前后4周，给T组的日粮中添加100克/头/天的含有酿酒酵母（Sc 47 - CNCM I - 4407）的产品。干物质摄入量和体况评分不受日粮处理的影响。相比之下，有机物、蛋白质、中性洗涤纤维和酸性洗涤纤维的消化率显著提高（<0.01）。T组的产奶量更高（10.5千克对9.2千克，<0.05），但乳脂含量更低（76.0克/千克对80.1克/千克，<0.05）。处理组的水牛标准奶（FPCM = 740千卡）产量更高（16.8千克对15.0千克，<0.05），而马苏里拉奶酪产量不受处理影响（>0.05）。这些结果表明，在过渡期给水牛日粮补充酿酒酵母可显著提高营养物质消化率和产奶量。这些结果值得进一步研究。
