Alternative feeds can reduce milk production costs, but quality attributes of dairy products may also be affected. The physicochemical, sensory, and fatty acid (FA) profiles of Minas frescal cheese produced from grazing cows fed different levels of cracked babassu coconut (CBC) were investigated in the present study. Actual and adjusted cheese yields in kg cow⁻¹ d⁻¹ decreased as CBC levels increased in the supplement. Physicochemical composition was unaltered, whereas proportions of trans-11 18:1 and cis-9, trans-11 CLA linearly increased in cheese from cows fed increasing CBC levels. Conversely, the n-6:n-3 FA ratio showed a linear decreasing pattern. Yellow intensity decreased linearly, whereas a quadratic response was observed for aroma and appearance scores. In conclusion, feeding CBC to grazing cows induces beneficial changes in FA composition and other quality attributes of Minas frescal cheese, but cheese yield in kg cow⁻¹ d⁻¹ is strongly reduced, limiting the use of CBC in dairy cow diets.

替代饲料可以降低牛奶生产成本，但也可能影响乳制品的质量属性。在本研究中，研究了由饲喂不同水平的巴巴苏椰子 (CBC) 的放牧奶牛生产的 Minas frescal 奶酪的理化、感官和脂肪酸 (FA) 特征。随着补充剂中 CBC 水平的增加，以 kg 牛为单位的实际和调整后的奶酪产量^-1 d ^-1下降。理化成分没有改变，而反式-11 18:1和顺式-9、反式的比例-11 CLA 在来自奶牛的奶酪中线性增加，CBC 水平增加。相反，n-6:n-3 FA 比率显示线性下降模式。黄色强度线性下降，而观察到香气和外观评分的二次响应。总之，给放牧奶牛喂食 CBC 会导致 Minas frescal 奶酪的 FA 组成和其他质量属性发生有益变化，但 kg 奶牛的奶酪产量^-1 d ^-1大大降低，限制了 CBC 在奶牛日粮中的使用。
