【摘要】：本试验旨在研究四层层叠密闭式本交笼养鸡舍春季不同位置舍内环境参数差异及其相关性。以四层层叠密闭式本交笼养鸡舍为研究对象,每天6∶00~8∶00、12∶00~14∶00和18∶00~20∶00测定蛋鸡舍内各观测点风速、温度、相对湿度、光照强度、CO_2浓度和O_2含量环境参数。从湿帘端到风机端风速和CO_2浓度显著增加(P0.05),温度和相对湿度呈逐渐降低趋势。H_(1.47m)和H_(2.33m)测定点的光照强度、风速和温度显著高于H_(0.64m)和H_(3.16m)(P0.05),而相对湿度呈相反趋势(P0.05)。H_(0.64m)和H_(1.47m)的CO_2浓度显著高于H_(2.33m)和H_(3.16m)(P0.05),而O_2含量则呈相反趋势(P0.05)。12∶00~14∶00的光照强度、风速、温度和O_2含量显著高于其它时间段(P0.05),而相对湿度和CO_2浓度则较低(P0.05)。相关性分析显示风速与温度、风速与O_2含量以及温度与O_2含量呈显著正相关,而相对湿度与风速、温度和O_2含量以及CO_2浓度与温度和O_2含量呈显著负相关。本结果建议应根据鸡舍内环境实际情况以及各个参数间的相关性合理调整饲养管理以提高种鸡生产性能和养殖场经济效益。
[Abstract]:The purpose of this experiment was to study the difference and correlation of environmental parameters in four layers of closed caged chicken coop in spring. In this paper, four layers of closed caged chicken coop were used as the research object. The environmental parameters of wind speed, temperature, relative humidity, light intensity and O _ 2 content in each observation point were measured at 6: 00, 8: 00, 12: 00, 14: 14 and 18: 00, 20: 00, respectively, and the environmental parameters of O _ 2 content were measured. The wind speed and the concentration of CO_2 increased significantly from the wet curtain to the fan end. The temperature and relative humidity decreased gradually. The light intensity of the measuring points was 1.47 m and 2.33 m. The wind speed and temperature are significantly higher than that of Hashmatter 0.64m) and Hashmatter 3.16mP0.05m, while the relative humidity is in the opposite direction; the CO_2 concentration of P0.05U (0.64m) and Hampong 1.47m) is significantly higher than that of H201 2.33m) and HSCH 3.16mP0.05m, while the O2 content shows a reverse trend: P0.05w. 12: 00: 1400 light intensity, wind speed, wind speed, The temperature and the content of O _ 2 were significantly higher than those of other time periods, while the relative humidity and the concentration of CO_2 were lower than those of other periods. The correlation analysis showed that there was a significant positive correlation between wind speed and temperature, between wind speed and O _ (2) content, between relative humidity and wind speed, between temperature and O _ (2) content, and between CO_2 concentration and temperature and O _ (2) content. The results suggested that the breeding management should be adjusted reasonably according to the actual conditions in the henhouse and the correlation among the various parameters in order to improve the production performance and the economic benefit of the breeding farm.
