The increasing animal numbers have a potential impact on the air quality of stables. The aim of this study was to assess the microbial load in the barn air from the day of entry of the chickens to the day of removal for slaughter. A total of 10 measurements in two fattening periods were conducted in a poultry farm with a capacity of 400 chickens in Styria, Austria. The samples were collected with an Air-Sampling Impinger for the investigation of mesophilic bacteria, staphylococci and enterococci. Chicken skin swab samples were collected to detect . The total colony forming units per cubic meter of mesophilic bacteria of the first measurement series of period I was 7.8 × 10 and increased to 1.4 × 10 at the end and at the fattening period II it increased from 2.5 × 10 to 4.2 × 10. In the measurement series of the fattening period I, the concentration of spp. increased from 0 to 4.9 × 10 CFUs/m and from 0 to 2.1 × 10 CFUs/m in the fattening period II. could not be found on the chicken skin. An interesting finding was the increase of staphylococci while the intestinal enterococci were not detectable in the air of the barn toward the end of both fattening periods.
动物数量的增加对畜舍空气质量有潜在影响。本研究的目的是评估从鸡进入畜舍到出栏屠宰期间畜舍空气中的微生物负荷。在奥地利施蒂里亚州一个可容纳400只鸡的家禽养殖场，在两个育肥期共进行了10次测量。使用空气采样冲击器采集样本，以调查嗜温菌、葡萄球菌和肠球菌。采集鸡皮肤拭子样本以进行检测。第一阶段第一次测量系列中每立方米嗜温菌的总菌落形成单位为7.8×10，在该阶段结束时增加到1.4×10，在育肥期II从2.5×10增加到4.2×10。在育肥期I的测量系列中， spp.的浓度从0增加到4.9×10 CFUs/m，在育肥期II从0增加到2.1×10 CFUs/m。在鸡皮肤上未发现 。一个有趣的发现是，在两个育肥期接近尾声时，畜舍空气中葡萄球菌数量增加，而肠道肠球菌未被检测到。
