摘  要：
本研究旨在比较冬季不同建筑类型奶牛舍内外气载细菌和真菌的含量变化。选择3种建筑类型的奶牛舍,对舍内、运动场、净道、凉棚及场外上风向和下风向5和50m处的气载微生物进行同期采样分析。结果显示,不同建筑类型奶牛舍内微生物含量不同,气载细菌的含量变化为1 540~10 487CFU/m3,只设顶棚的棚舍细菌含量最高;气载真菌的含量变化为169~731CFU/m3,卷帘舍的真菌含量最高,且所有舍晚上的细菌和真菌含量均高于早上和中午。从舍内外微生物的空间分布得出,舍内或运动场的细菌含量高于净道,场外下风向处的细菌含量高于上风向处,但真菌的空间分布变化不明显。本研究结果可为奶牛舍环境的改善和奶牛疾病预防提供参考。

摘  要：
The present objective of the study was to investigate the concentrations of indoor and outdoor and airborne fungi of three styles of dairy cowsheds in winter.The sampled sites included the shed,exercise yard,net road,sunshade,5or 50 mdistance upwind or downwind outside each dairy farm.The results showed that the indoor microorganism concentration varied from the shed styles.The concentrations of airborne bacteria ranged from 1 540 to 10 487CFU/m3 in all three sheds,and among all sheds,the bacteria concentration in the shed with only roof was the highest.The concentrations of airborne fungi ranged from 169 to 731CFU/m3 in all sheds,and the fungi concentration in the shed with curtain was the highest.Moreover,both bacteria and fungi concentrations in the evening were higher than that at noon and in the morning.From the spatial distribution of indoor and outdoor microorganisms,the bacteria concentrations in the sheds or at the exercise yard were higher than that at the net road in each farm,and the bacteria concentration in downwind was higher than in upwind,while the spatial distribution of fungi showed no significant difference among all sampled sites.The research results would provide some references for improving environment of cowshed and preventing from diseases.
