Two Types Of Sheds Environments In Hebei Province Quality Monitoring And Analysis

Summary as in recent years raised chicken industry of rapid development, currently in China in varieties, and nutrition, and disease control and feeding technology area and international advanced level of gap gradually narrow, but in environment control area also exists with is large of gap, environment control on poultry production of effect has been no are should have of attention, in domestic currently basic solution has nutrition and feeding technology, problem of premise , sheds environment control in poultry production in the up with very important of role. Poultry for good living environment is a prerequisite for chickens healthy, are important measures to improve performance is to improve the product quality guarantee.Microclimate sheds environments control problem is of concern to the producers. Layer breeding in scale, high density environments under conditions of poor, on production performance of laying hens and their negative impact on health. Laying hens need to understand the effect of various environmental factors on performance of laying hens, and create an ideal breeding environment, together with the scientific management, to obtain a higher degree of economic efficiency.The research’s test site is Xin Lu and Wei Ye in Hebei province, respectively in winter and summer air quality monitoring and analysis of the State of their sheds. Sheds environments factors including temperature and humidity, light intensity, pernicious gases, dust and wind speed and other aspects, chickens in different seasons, environmental requirements are different, and needs to focus on the control of environmental factors is also different. This test in order to enhance production of laying hens, different for different types of chicken coops chicken coops for continuous monitoring of the seasons, by sheds environments on different types of quality analysis of dynamic change of State and as well as on the economic benefits of chicken coops and a comprehensive analysis of performance, provide the scientific basis for the transformation of new sheds. The results are as follows:①Closed sheds summer and winter homes inside and outside of average temperature difference respectively for 0.2℃and 10.5℃, summer and winter homes inside and outside of average humidity difference respectively for 2.4% and 10.3%, due to closed sheds of ventilation way different, makes sheds of temperature and humidity of suitable, by homes outside climate effect smaller; half open sheds summer and winter homes inside and outside of average temperature difference respectively for 1.1℃and 8.4℃, summer and winter of average humidity difference for 4.4% and 22.7%, Half-open structures Chicken Coop has the ability of cold-heat-stroke prevention, but the outside air temperature and humidity and care makes little difference.②Closed poultry house and half-open sheds of NH₃, H₂S and CO₂ show certain trends, average concentrations are higher during the Conservancy. CO₂ and dust of summer closed poultryhouse above the half-open sheds 531 ppm and 1.5 mg/m³, respectively .Half-open sheds in winter light and the wind speed and CO₂ above closed sheds 666 ppm, 8.87 lx and 0.08 m/s, respectively.③Environmental parameters in the different types of sheds affected on average egg weight and, rate of eggs and cull-and-death rates has an impact. Half-open chicken coop egg production rate is not significant lower than the Enclosed one （P>0.05）; The difference is egg laying hens than less than half-open ones, and the difference is not significant （P>0.05）; cull-and-death rates ignificantly lower than half-open chicken house （P<0.05）. Different types of closed-end sheds sheds environments in different seasons of stability of half-open sheds stable, closed-end compared to the chicken house and half-open chicken house building cost per square metre than half-open chicken house savings of $ 57.
