摘要
选择40周龄新罗曼商品代蛋鸡800只,随机分为4组。对照组喂基础日粮,试验1,2,3组分别用1%,1.5%和2%的豆油替代等量的玉米。结果表明,试验3组、2组、1组鸡的产蛋率分别较对照组高4.85%,3.53%和2.28%,蛋重分别较对照组高2.42%,2.10%和0.97%,料蛋比分别比对照组低3.76%,3.29%和1.88%。产蛋鸡日粮中油脂的适宜添加量为1.5%~2.0%。
Effects of soybean oil on performance of laying hens in high-temperature condition were determined in this trial. Four dietary treatments, consisting of basal diet(control) and basal diets adding 1%,1.5 % and 2 % soybean oil, respectively, substituting the same weight of corn, were allotted to 800 laying hens of 40 - week old randomly assigned to 4 groups with 4 replicates. The results were as followings: compared with the control, laying rates in test group 3, 2, 1 increased by 4.85 % (P 〈: 0.05), 3.53 % (P 〈 0.05) and 2.28 % (P 〉 0.05) ; egg weight increased by 2.42 %, 2.10 % and 0.97 % ; feed efficiency increased by 3.76 %, 3.29 % and 1.88 % ; the profit from every laying hen increased by 0.17yuan, 0.18 yuan and 0.09 yuan, respectively. The conclusion could be drawn that it would be suitable to supplement diet with 1.5 % to 2.0 % soybean oil during summer.
