摘　　要：试验研究了红茶末对淮南麻黄鸡生产和繁殖性能的影响。将290日龄淮南麻黄鸡种鸡528只(母鸡480只,公鸡48只),随机分成4组(每组4个重复),分别饲喂添加0(对照组)、0.5%、1.5%、2.5%红茶末4种种鸡日粮,试验持续50天。日粮中添加0.5%的红茶末,除平均蛋重低于对照组0.39g(P<0.01)外,淮南麻黄鸡的产蛋率、饲料利用率、健雏率和出雏公鸡率均有提高的趋势(P>0.05);种蛋受精率比对照组高6个百分点(P<0.05);种蛋合格率和雏鸡初生重分别比对照组高4.7和4.8个百分点(P<0.01)。高浓度红茶末(1.5%或2.5%)对淮南麻黄鸡产蛋及繁殖性能有负面影响。淮南麻黄鸡日粮添加适量红茶末可改善其生产和繁殖性能。The research was to study effects of black tea powder on egg laying and reproductive performance in Huainan Spotted-yellow Chicken. 528 Huainan Spotted-yellow Chickens including 480 female and 48 male （290 d of age） were randomly allotted into four treatments with four replications and were used in 50 d performance trail with four diets： Control group with zero percent black tea powder in feed, three trail groups with 0.5 percent, 1.5 percent and 2.5 percent black tea powder supplemented in control diet, respectively. The diet with 0.5 percent black tea powder showed a trend to increase laying rate, feed conversion rate, percentage of healthy chicks, and hatchability of male chicks （P〉0.05） compared to control group. Though the average eggs weight was lower than that of control group （0.59 g） at the most significant level （P〈O.01）, Fertility of setting eggs was significantly higher six percent than that of control group （P〈0.05）; percentage of setting eggs and weight at birth were 4.7 percent and 4.8 percent higher compared to control group, respectively, which were most significantly higher than control group （P〈0.01）. The diets with more black tea powder （1.5% and 2.5%） had negative impact on egg laying and reproductive performance of Huainan Spotted-yellow Chicken. Diet with black tea powder of suitable concentration could improve the laying performance and reproductive performance in Huainan Spotted-yellow Chicken.
