LUO Jin-yin1,YU Jie1,2,LI Hong-sheng1,LI Xin-pu1(1.Lanzhou Institute of Animal Science and Veterinary Pharmaceutics,Chinese Academy of Agricultural Sciences,Lanzhou,Gansu 730050,China;2.Jiangsu Animal Husbandry and Veterinary College,Taizhou,Jiangsu 225300,China)  
The study was conducted to investigate the prevalence of clinical and sub-clinical mastitis and the risk factors in 2 173 cow milk samples from 8 540 milk regions of six cities(Lanzhou,Chengdu,Haerbin,Zhengzhou,Jinan and Nanchang) in China.The results showed that the cow prevalence of clinical and sub-clinical mastitis were 5.38% and 59.36%,respectively.The region prevalence was 1.65% and 31.62%,respectively.The average number of somatic cells in bulk milk samples was 7.36×105/mL.The bacteriological analysis of 340 milks samples from 280 diagnosed cows showed that main pathogenic bacteria were Streptococcus.dysgalactiae,E.coli,Streptococcus.agalactiae and Staphylococcus aureus,which was 91.11% of total bacteria.
