| 中文摘要: |
| 对育雏季节分别为春、夏和秋季的3 批南海黄鸡的生产性能进行分析，研究育雏季节对饲养效果的影响。结果表明，秋季育雏的种鸡产蛋率上升速度最快，在开产后的第7 周达到产蛋最高峰，然后缓慢下降；秋季育雏的种鸡全期产蛋量最高，达到110.47 枚，其次是夏季育雏（100.75 枚）和春季育雏（95.38 枚）；春、夏、秋季育雏的种鸡产蛋期间采食量分别为113.34、116.21、111.89 g/d，秋季育雏的最低，夏季育雏的最高。秋季育雏的每枚种蛋耗料量最低（170.15 g），春季育雏的最高（199.63 g）；春、夏、秋季育雏的南海黄鸡成活率分别为94.46%、96.22% 和96.00%，夏季育雏的成活率最高，春季育雏的成活率最低。可见，秋季育雏的南海黄鸡父母代种鸡，开产后产蛋率迅速上升，高峰产蛋率最高，饲料消耗量小，每枚种蛋耗料量最少，饲养成本最低，成活率高。 |

| The effects of different brood seasons on laying performance，production performance of Nanhai Yellow Chicken parent generation breeders in three brood seasons（ spring，summer and autumn） were analyzed.The results showed that the laying rate of breeders brooding in autumn increased fastest，and reached the peak in the seventh week after first laying，then the laying rate decreased gradually. The breeders brooding in autumn exhibited the highest egg production，with 110.47 for each breeder，followed by summer（ 100.75） and spring （95.38）.During the laying period，the feed intake of breeders brooding in spring，summer and autumn，was 113.34 g/d，116.21 g/d and 111.89 g/d，respectively. Furthermore，feed consumption for each egg was the lowest in autumn brood（ 170.15 g） and the highest（ 199.63 g） in spring brood. In addition，the survival rates of stock brooding in spring，summer and autumn，were 94.46%，96.22% and 96.00%，respectively. Compared to the other two seasons，chickens brooding in autumn had the highest laying rate，the lowest feed consumption and the highest survival rate. |
