| 摘 要： | 以砻糠和玉米秸秆为主要纤维源,在日粮等能量、等蛋白的前提下,采用2因子5水平的二次回归正交旋转组合设计试验,研究纤维酶制剂添加水平和日粮粗纤维水平对料重比的影响,建立了两因素对料重比关系的数学模型;最后确定了纤维酶制剂和日粮粗纤维在生长鹅日粮中的最佳配比为:纤维酶制刺添加水平为0.347%、日粮粗纤维水平为5.68%,料重比为3.21. |
| 关 键 词： | 生长鹅 日粮粗纤维 纤维酶制剂 料重比 饲料 配比 |

| Abstract: | Taking rice husk and corn stalk as main source of fiber and under the conditions of equal energy and equal protein of the rations,an experiment by means of universal rotational combinational design by three-factor five-level quadratic regression was carried out to study the effect of adding level of cellulase preparations and content level of crude fiber in the rations on the feed/weight gain ratio.A mathematical model of relation between two factors and feed/weight gain ratio was established;finally the op... |
| Keywords: | growing goose crude fiber in ration cellulase preparation feed/weight gain ratio feed proportioning |
