The aim of this study was to evaluate the effect of the replacement of corn with cassava peel in the diets of dairy cows. Eight Holstein cows were used. The experimental treatments consisted of four replacement levels of corn with cassava peel (0, 33, 66, and 100 %). The replacement of corn with cassava peel linearly decreased the intake and digestibility of dry matter and organic matter, but did not alter the intake of neutral detergent fiber and crude protein. In addition, there was a linear decrease in milk production. The milk components (g/kg) of fat, protein, lactose, and total solids were not altered. Although cassava peel decreased intake, digestibility, and milk production, the replacement of corn with cassava peel may be advantageous in locations close to the starch industry.
本研究的目的是评估用木薯皮替代奶牛日粮中玉米的效果。使用了8头荷斯坦奶牛。实验处理包括用木薯皮替代玉米的四个水平（0、33、66和100%）。用木薯皮替代玉米使干物质和有机物的摄入量及消化率呈线性下降，但未改变中性洗涤纤维和粗蛋白的摄入量。此外，产奶量呈线性下降。乳成分（g/kg）中的脂肪、蛋白质、乳糖和总固体未发生改变。尽管木薯皮降低了摄入量、消化率和产奶量，但在靠近淀粉行业的地区，用木薯皮替代玉米可能具有优势。
