【摘要】：試驗(yàn)對(duì)北方地區(qū)某大型鐘樓式奶牛舍一年內(nèi)不同季節(jié)舍內(nèi)、外的空氣環(huán)境指標(biāo),包括溫?zé)岘h(huán)境指標(biāo)、CO2和NH3含量、空氣中的粉塵和微生物含量進(jìn)行測(cè)定,旨在了解其變化規(guī)律,評(píng)價(jià)其是否滿足奶牛健康生產(chǎn)的要求,以便為北方地區(qū)奶牛舍的設(shè)計(jì)和日常管理提供理論依據(jù)。結(jié)果表明,所測(cè)指標(biāo)隨季節(jié)或時(shí)間均呈現(xiàn)出一定的變化規(guī)律;所監(jiān)測(cè)奶牛舍夏季舍內(nèi)風(fēng)速低于標(biāo)準(zhǔn),中午(14∶00)舍內(nèi)溫度超過27℃,溫濕指數(shù)(THI)69,奶牛在夏季產(chǎn)生輕度的熱應(yīng)激;除此以外,在不同時(shí)間、不同位點(diǎn)監(jiān)測(cè)的其他各項(xiàng)空氣環(huán)境指標(biāo)均符合奶牛的飼養(yǎng)標(biāo)準(zhǔn)。綜合測(cè)定結(jié)果,試驗(yàn)所監(jiān)測(cè)的鐘樓式奶牛舍較適合北方地區(qū)的奶牛養(yǎng)殖,但建議增加防暑降溫措施,以減少奶牛在夏季產(chǎn)生的熱應(yīng)激。
[Abstract]:The air environment indexes, including temperature and heat environment index, CO2 and NH3 content, dust and microbial content in air, were measured in a large bell tower dairy cow house in the north of China in different seasons in a year, in order to understand its changing law. To evaluate whether the dairy cattle can meet the requirements of healthy production in order to provide a theoretical basis for the design and daily management of dairy cattle houses in northern China. The results showed that the indexes showed a certain variation with season or time. The wind speed was below the standard in summer, the temperature was over 27 鈩，
