冬季笼养蛋鸭舍生产性能与环境因子关联性研究
|
摘要
试验系统研究了标准笼养蛋鸭舍冬季生产性能与环境因子分布及回归关系。随着氨气浓度由(0.17±0.04)mg/kg显著(P<0.05)升高至(0.46±0.07)mg/kg,中间层蛋鸭产蛋率由(75.45±0.82)%显著(P<0.05)下降至(66.70±0.81)%。上层笼白昼平均光照强度为(42.31±1.21)lx,显著(P<0.05)高于下层的(26.96±0.82)lx,并且夜间下层笼光照强度低于2 lx。上层蛋鸭产蛋率为(80.90±0.97)%,显著(P<0.05)高于下层的(64.65±1.26)%。结果提示:为提高蛋鸭生产性能,需要研究新型通风换气技术,合理布局舍内光源,改良水禽笼养技术。
This experiment studied the distribution and regressive relationship between production performance and environmental factors in caged duck house in winter when the environmental control was extremely difficult to carry out. The results showed that laying rate of middle cage ducks decreased from(75.45±0.82)% to(66.70±0.81)% with the increase of ammonia concentration from(0.17±0.04) mg/kg to(0.46±0.07) mg/kg(P<0.05). Illumination intensity of high cages(42.31±1.21) lx was higher than that of the low cages during day time(P<0.05). Illumination intensity of low cages was lower than 2 lx in the night. Egg laying rate of high cage ducks(80.90±0.97)% was higher than that of the low cage(P<0.05). In conclusion, it is suggested to develop novel techniques on ventilation and optimize lighting methods to improve duck production performance.
