不同三元杂交组合肉鸽生产性能比较
Comparison on Production Performances of Meat Pigeons with Different Three-way Cross Combinations
摘要
Abstract
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 of young pigeons,the body weight of 21-day and 28-day young pigeons,LX♂×Y♀ was preliminarily determined to be better,but its overall production performance need further improvement.关键词
