The result of unclinical diagnosis and identify some bacteria caused Mastitis

Abstract

A study was conducted to investigate the present situation of mastitis in dairy cows raised by households in Gialam and Longbien districts using California Mastitis Test (CMT) on 435 cows. It was recognized that 39.77% (173/435) of the total cows tested were positive. Among the mastitis-affected cows, those with 1, 2, 3 and 4 udders affected with mastitis accounted for 32,3%, 27,74%, 21,97% , and 17,9%, respectively. In milk samples which were collected from mastitis-suffering cows, there were three types of bacteria isolated with high incidence, viz.Streptococcus (85.00%), staphylococcus (78,75%) and E.coli (30%). Use of antibiotic tests showed that these bacteria were sensitive to marbofloxacin, ciprofloxacin and cephalothin. It was therefore reccommneded that these antibiotics be used to treat mastitis in dairy cows.
