养殖密度和光照强度对笼养蛋鸭生产性能和蛋品质的影响

Effects of Breeding Density and Light Intensity on Production Performance and Egg Quality of Caged Laying Ducks

该试验选用300日龄健康状况良好的青壳3号蛋鸭1380只,研究笼养密度及光照强度对蛋鸭生产性能和蛋品质的影响。结果表明,3只/笼的养殖密度中蛋鸭的产蛋率显著高于13只/笼和7只/笼的养殖密度(P<0.05);破损蛋率和料蛋比显著低于13只/笼和7只/笼的养殖密度(P<0.05)。60~70 Lx光照强度下,蛋鸭的产蛋率显著高于其他光照强度处理组(P<0.05);破损蛋率显著低于其他光照强度处理组(P<0.05)。综上所述,以60~70 Lx光照强度,3只/笼的养殖密度蛋鸭的生产性能最佳,且在一定程度上提升了鸭蛋的品质。

A total of 1380 Qingshelled No.3 laying ducks with good health at 300 days of age were selected to study the effects of cage density and light intensity on the production performance of laying ducks.The results showed that:the laying rate of 3 ducks per cage was significantly higher than that of 13 ducks per cage and 7 ducks per cage(P<0.05).The broken egg rate and feed to egg ratio were significantly lower than them of the breeding density of 13 eggs/cage and 7 eggs/cage(P<0.05).Under 60~70 Lx light intensity,the laying rate of laying ducks was significantly higher than that of other light intensity treatment groups(P<0.05).The rate of damaged eggs was significantly lower than that in other light intensity treatment groups(P<0.05).In summary,under 60~70 Lx light intensity,the breeding density of 3 birds/cage has a promoting effect on the production performance of laying ducks,and improves the quality of duck eggs to a certain extent.
