不同三元组合肉鸽生产性能的比较

The determination of production performance in different three-breed crosses of pigeons

本研究为筛选生产性能较佳的肉鸽三元组合。组成四个杂交组合,每组80对,试验期8个月,记录生产性能。试验期末,统计各组繁殖性能、28日龄乳鸽体尺和屠宰性能。结果显示,四个杂交组合后代28日龄体重HE1(586g)>E3K(578g)>HW(569g)>HK(561g),且HE1显著大于HW、HK(P<0.05);体尺指标之间没有显著差异;屠宰测定中半净膛率HE1(79.42%)显著大于E3H(76.89%)(P<0.05),全净膛率HW(71.71%)显著大于E3H(69.69%)(P<0.05)。亲鸽,产蛋间隔没有产生差异(P>0.05);产蛋数HW(13.96个)显著大于E3H(13.27个)(P<0.05);出栏乳鸽数HW(11.44只)显著大于HE1(10.22只)、E3K(10.33只)(P<0.05)。综合各项指标,HW组合生产性能最佳。

The study aims to determine and analyze production performance in different three-breed crosses of pigeons.80 pairs each of four three-breed crosses of pigeons were chose to determine the production performance.At the end of experiment,reproductive performance of breeding pigeons,body size and slaughter performance of 28-day pigeons were measured and analyzed.The result showed,the 28-day weight of the offspring of four cross combinations:HE1(586g)>E3K(578g)>HW(569g)>HK(561g),and HE1 was significantly higher than HW and HK(P<0.05);there was no significant effect on the body size indexes.The half eviscerating percentage of HE1(79.42%)was significantly higher than E3H(76.89%)(P<0.05),the eviscerating percentage of HW(71.71%)was significantly higher than E3H(69.69%)(P<0.05).The egg production intervals of different crosses had no significant differences(P>0.05);the egg number of HW(13.96)was significantly higher than E3H(13.27)(P<0.05),the marketable fattened stock of pigeons of HW(11.44)was significantly higher than HE1(10.22)and E3K(10.22)(P<0.05).(conclusion)In conclusion,the production performance of HW was the best.
