Abstract Goat milk composition can be influenced by diet, such as adding exogenous enzymes into the feed to improve digestibility. The objective of this study was to evaluate milk composition and cheese goat yield when ruminants consumed an enzymatic extract obtained from spent Pleurotus ostreatus substrate. A one-way experimental design was used in this study. Enzymatic activity and milk composition were measured (fat, lactose, minerals, protein, total solids and non-fatty solids) while fresh cheese yield and their traits, such as color and texture, were also were determined. The enzymatic extract presented xylanase, laccases and cellulases activity (32227.72, 2822.33 and 69.03 IU MS. g-1, respectively). Results indicate that the enzymatic extract increased the cheese yield (P

使用用过的平菇底物补充山羊以增加新鲜奶酪的产量

摘要 山羊奶的成分会受到日粮的影响，例如在饲料中添加外源酶以提高消化率。本研究的目的是评估反刍动物食用从用过的平菇底物获得的酶提取物时的牛奶成分和奶酪山羊产量。本研究采用单向实验设计。测量了酶活性和牛奶成分（脂肪、乳糖、矿物质、蛋白质、总固体和非脂肪固体），同时还确定了新鲜奶酪的产量及其特性，如颜色和质地。酶提取物具有木聚糖酶、漆酶和纤维素酶活性（分别为 32227.72、2822.33 和 69.03 IU MS.g-1）。结果表明酶提取物增加了奶酪产量（P
