摘要
探讨不同建造结构肉用山羊舍内部环境参数的动态变化规律,为肉用山羊养殖场羊舍设计、旧舍改造及饲养管理改进等提供参考.对简州大耳羊3种类型羊舍夏季内部5种空气环境参数进行测定,结果表明,舍内温、湿度对舍内有害气体浓度存在不同程度的影响,气温是影响环境因子的主要因素,气温与CO2浓度呈显著性负相关(P<0.05),与NH3、H2S浓度呈极显著正相关(P<0.01);采用舍外排污方式的A型舍相对湿度、CO2、NH3、H2S浓度等环境参数显著低于舍内排污的B型舍(P<0.01);与舍外排污的C型舍相比,通风面积较大和通风速率更高的A型舍NH3、H2S浓度显著低于C型舍(P<0.05).结论:A型舍的空气质量最佳,舍饲山羊圈舍排污方式应选择舍外排污.
This project analyzes dynamicvariationrules of internal environment parameters of meat goat houses and aims at providing reference to the design, transformation of the old goat houses as well as the raising and managing technology. By measuring the five environmental parameters of three kinds of Jianyang Da'er goat houses, the results showed that internal temperature and humidity have different impacts on the concentrations of harmful gases. What's more, temperature is the main factor which influences environmental factors. The project also proves that temperature has a significant negative correlation with CO2 concentration(P〈0.05) while temperature has a significant positive correlation with the concentrations of NH3 and H2S(P〈0.01). The relative humidity, concentrations of CO2, NH3 and H2 S and other environmental parameters of the house using the A-type outside drainage way are significantly lower than the B-type inside drainage way(P〈0.05). Compared with the C-type outside drainage way, the concentrations of the NH3 and H2 S of A-type are obviously lower because of its larger ventilation areas and higher ventilation rates. Thus, the result of this project is that A-type house has the best air quality and the goat house should use the outside drainage way.
