We aimed to evaluate the chemical composition, production yield, and economic viability of Minas Frescal cheese produced with milk from buffaloes supplemented with açai seed as a substitute for corn meal. The experiment used five Murrah crossbred buffaloes with a mean body weight of 577 ± 20.4 kg, maintained under Megathyrsus maximus cv. Mombaça grazing in a 5 × 5 Latin square design. The treatments comprised four concentrate supplements, in which açai seed replaced corn meal at 0, 33, 66, and 100% substitution, and a control with no concentrate supplementation. Replacement of corn meal with açai seed in buffalo diet had no effect on chemical composition of produced cheese (P > 0.05) nor was there any difference in chemical composition between the control group and animals supplemented with concentrate (P > 0.05). The adjusted cheese yield (kg cheese/cow/day) demonstrated a quadratic pattern with maximum production at 33% açai seed substitution (P < 0.05). Hence, the profitability index (percentage of gross revenue) was greatest at this replacement level. In conclusion, 33% açai seed replacement of corn meal in the supplement of buffalo under a grazing regime improved the individual yield of Minas Frescal cheese without changing its chemical composition.

我们旨在评估米纳斯·弗雷斯卡奶酪的化学成分，产量和经济可行性，这些奶酪是用水牛牛奶和阿萨伊种子代替玉米粉制成的牛奶制成的。实验使用了五只Murrah杂交水牛，平均体重为577±20.4 kg，保持在Megathyrsus maximus cv下。蒙巴萨采用5×5拉丁方形设计放牧。这些处理包括四种浓缩补充剂，其中阿萨伊种子以0％，33％，66％和100％的取代率代替玉米粉，以及不添加浓缩剂的对照。在水牛日粮中用阿萨伊籽代替玉米粉对所生产奶酪的化学成分没有影响（P > 0.05）对照组和补充浓缩物的动物之间的化学成分也没有任何差异（P  > 0.05）。调整后的奶酪产量（公斤奶酪/牛/天）表现出二次模式，最大产量为33％阿萨伊种子替代率（P  <0.05）。因此，在此替代级别上，获利能力指数（占总收入的百分比）最大。总之，在放牧条件下，在水牛补给品中添加33％的玉米粉代替玉米粉可以提高Minas Frescal奶酪的单产，而无需改变其化学成分。
