| 摘 要： | 将体况相近的240日龄河北柴鸡480只随机分为4组,对照组饲喂玉米-杂粕型基础日粮,处理组放牧加补饲:试验组Ⅰ补料60%;试验组Ⅱ补料40%;试验组Ⅲ自由采食补料。结果表明:在放牧条件下,降低补料量后河北柴鸡产蛋率和蛋重下降极显著(P<0.01);但试验组Ⅲ产蛋率和蛋重无显著变化(P>0.05)。降低补料量极显著提高蛋黄罗氏比色扇级数(P<0.01),显著提高蛋黄比率(P<0.05),降低蛋白比率(P<0.05),但同时哈氏单位显著降低(P<0.05)。

| Abstract: | Abastract :480 Hebei hens were randomizedinto 4 treatments , The contrast growp was feed basaldiet consisting of a corn-soybean -mixed meal ; The control growps were put out to the pasture-herd: growpⅠ:60 % supplementary feed amount ;growp Ⅱ:40 % supplementary feed amount ;growpⅢ:freedomon supplementaryfeed amount .The results showed as follows .Comparedtothecontrol groups ,the producingrate andegg wight decreasedsignificantly (P<0.01) ,but thelibertybasal treatment was not remarkbly changing (P>0.05).Decrease supplement feed amount couldi mprove the quanlity of eggs ,remarkblyincrease yolk ratio(P<0.05) ,and decrease albumen ratio(P<0.05) ,But the Ha -Fu unit remarkbly cuts down (P<0.05) . |
