This study evaluated wheat grain which was treated with xylose in aqueous Ca-Mg lignosulphonate solution at elevated temperatures (WeiPass®) in order to reduce ruminal degradation of starch and crude protein. The two tested isoenergetic and isonitrogenous diets contained on dry matter (DM) basis either 16% maize grain and 6.4% soybean meal (Diet CON) or 17.8% xylose-treated wheat and 4.6% soybean meal (Diet Wheat). Thirty-six German Holstein dairy cows were assigned to one of the two groups according to parity, body weight after calving, and milk yield during the previous lactation. Data collection started at 21 d before the expected calving date until 120 d in milk. The average of DM intake, energy-corrected milk (ECM) yield, and milk fat and protein yields (all given as kg/d) were 18.9, 28.7, 1.25, and 1.02 for Diet CON and 19.3, 32.5, 1.36, and 1.11 for Diet Wheat, respectively. Only ECM and milk protein yields were greater (p < 0.05) for cows receiving Diet Wheat. In conclusion, the xylose-treated wheat grain can replace maize grain and part of soybean meal in diets for lactating dairy cows and may be an alternative feedstuff depending on overall ration composition and availability and costs of grain sources.
本研究评估了在高温下于含水的钙镁木质素磺酸盐溶液中用木糖处理的小麦籽粒（WeiPass®），以降低瘤胃中淀粉和粗蛋白的降解。两种等能量和等氮的受试日粮，以干物质（DM）计，一种含有16%的玉米籽粒和6.4%的豆粕（对照日粮），另一种含有17.8%的木糖处理小麦和4.6%的豆粕（小麦日粮）。36头德国荷斯坦奶牛根据胎次、产犊后的体重和前一个泌乳期的产奶量被分配到两组中的一组。数据收集从预计产犊日期前21天开始，直至产奶120天。对照日粮的干物质摄入量、能量校正乳（ECM）产量、乳脂肪和乳蛋白产量（均以kg/d计）的平均值分别为18.9、28.7、1.25和1.02，小麦日粮的相应值分别为19.3、32.5、1.36和
