摘 要:为筛选生产性能较佳的肉鸽三元杂交组合,选取3个杂交群体,即LX♂×Y♀(1组)、XL♂×Y♀(2组)和L♂×XY♀(3组),每组108对,试验期22~80周龄,记录生产性能;试验期末,统计各组繁殖性能,亲鸽52周龄、乳鸽21日龄和28日龄称重。结果表明:1组、2组和3组21日龄乳鸽体质量分别为497.1、486.1、487.2 g,差异不显著;28日龄乳鸽体质量分别为520.8、509.9、516.5 g,差异不显著;0~28日龄成活率1组>3组>2组;3个杂交组合开产日龄、开产体质量、开产蛋重和52周龄体质量均无显著差异;80周龄产蛋数1组(27.1个)显著大于2组(25.8个)、3组(24.9个),2组、3组差异不显著;80周龄出雏数1组(18.6只)、2组(18.6只)显著大于3组(16.3只),1组、2组差异不显著;80周龄出栏乳鸽数1组(17.4只)、2组(17.0只)显著大于3组(15.0只),1组、2组差异不显著;80周龄出雏数1组、2组相同,但0~28日龄成活率的差异造成80周龄出栏乳鸽数1组大于2组。综合考虑亲鸽出栏乳鸽数和乳鸽21日龄、28日龄体质量3项指标,初步认定LX♂×Y♀组合较佳,但整体生产性能还需进一步提高。The study aimed to screen out the three-way cross combination of meat pigeons with the best produc-tion performance.Three hybrid groups were formed as follow:LX♂×Y♀(group 1),XL♂×Y♀(group 2),L♂×XY♀(group 3),with 108 pairs in each group.The experimental period ranged from 22 to 80 weeks old,and the production performances were recorded.At the end of the experiment,the production performance of each group was counted,such as the 52-week weight of parent pigeons,the 21-day and 28-day weight of the young pigeons.The result showed that there was no significant difference in the 21-day weight of young pigeons among the three groups(the weight of group 1,group 2 and group 3 was 497.1 g,486.1 g and 487.2 g,respectively).There was also no significant difference in the 28-day weight of young pigeons among the three groups(the weight of group 1,group 2 and group 3 was 520.0 g,509.9 g and 516.5 g,respectively).The survival rate of 0-28 days young pigeons showed group 1>group 3>group 2.There were no signifi-cant differences in the day-old,body weight,egg weight at the first egg laying and 52-week body weight among the three groups.The number of eggs of 80-week pigeons in group 1(27.1 eggs)was significantly higher than that in group 2(25.8 eggs)and that in group 3(24.9 eggs),but there was no significant difference between group 2 and group 3.The number ofl 80-week brood in group 1(18.6)and group 2(18.6)was significantly higher than that in group 3(16.3),but there was no significant difference between group 1 and group 2.The marketable fattened stock of 80-week young pigeons in group 1(17.4)and group 2(17.0)was significantly higher than that in group 3(15.0),but there was no significant difference between group 1 and group 2.Although the number of 80-week brood in group 1 was as the same as that in group 2,the difference in survival rate of 0-28 days young pigeons caused that the marketable fattened stock of 80-week young pigeons in group 1 was higher than that in group 2.Considering the marketable fattened stock
