摘要: 为掌握规模化养猪场周围环境中的细菌数量与种类,以便为养猪场细菌性疾病的预防与控制提供依据,本试验在贵州省2个具有代表性的规模化养猪场中采集空气、饮用水、排污水、土壤和粪便样本进行细菌总数检测和优势菌落鉴定,结果显示,2个猪场的空气、饮用水、排污水、粪便和土壤样本细菌总数相应为(1.17~94.40)×104 CFU/m3、(0.15~1.83)×102 CFU/mL、(5.00~32.00)×105 CFU/mL、(0.46~26.40)×106 CFU/g和(0.30~52.30)×105 CFU/g,主要优势菌是葡萄球菌、链球菌、大肠杆菌、沙门氏菌、耶尔森菌、变形杆菌、巴氏杆菌、李氏杆菌、芽孢杆菌和梭状芽孢杆菌等。这些结果显示,除饮用水和土壤外,其余样本的细菌总数都符合国家规定的畜禽养殖场环境卫生要求,但存在一些条件致病菌或致病菌,这为养猪场细菌性疾病的预防与控制提供了重要的参考数据。

Abstract: To grasp the number and species of bacteria in the surrounding environment of the scaled pig farm and provide the basis for prevention and control of the bacterial disease of pig, the air, drinking and sewage water, faecal and soil samples were collected for bacteriological isolation and identification which from two-scale pig farms in Guizhou province. The results showed that the numbers of bacteria were respectively 1.17×104 to 94.40×104, 0.15×102 to 1.83×102, 5.00×105 to 32.00×105, 0.46 ×106 to 26.40×106 and 0.30×105 to 52.30×105 CFU/g in the above-mentioned samples, and of these bacteria, there were mainly Staphylococcus, Streptococcus, Escherichia, Salmonella, Yersinia, Proteus, Pasteurella, Listeria, Bacillus, Clostridium and so on. The results suggested that the numbers of bacteria in the other samples except drinking water and soil, were in line with requirement of national regulation for livestock and pourty farms, while there were some conditioned pathogen or pathogen,and these investigations provided an important reference data for prevention and control of pig bacterial diseases.
