To analyze the effects of some environmental factors such as herd, year, season of calving, stage of lactation on mastitis incidence, a total of 101147 monthly test day somatic cell counts collected from 13977 Iranian Holstein heifers calved between 2002 and 2006 in 183 herds were used. The event of mastitis in cows was coded as 1 if their somatic cell count at specific test day was greater tha...

Incidence of subclincial mastitis (SCM) among crossbred cattle from organized dairy farms was studied. The quarter-wise and animal-wise incidence of SCM was 15.62 and 43.33 per cent, respectively. Maximum number of animals (74.36 %) were having one quarter infection. Right-hind quarters were having higher incidence (38.18%) compared with other quarters. The incidence of SCM was lowest during fi...

Aim: This study was conducted to evaluate the concentrations of sodium (Na+) and potassium (K+) ions in milk of lactating dairy cows with and without subclinical mastitis as putative indicators for detecting subclinical mastitis in dairy cows. Materials and Methods: Thirty seven lactating dairy cows were screened for the evidence of subclinical mastitis using California mastitis test (CMT). The...

The study was carried out to investigate the current antibiogram status of bovine mastitis in and around Ranchi. The prevalence of mastitis was assessed by the results of bacteriological evacuation of mastitic milk samples collected from mastitis cases. A total of 150 cases of mastitis were studied for isolation followed by antibiotic sensitivity test. The major prevalent pathogens isolated wer...

Mastitis is one of the major and keen parameter for quality quantity milkproduction. The recent study was conducted to estimate occurrence rate mastitis in four differentseasons year its therapeutic cure Llivestock Experiment Station Nili Ravi Bhunikey. Forthis purpose, total 1188 milk samples were screened through California MastitisTest. Out samples, prevalence 9.7% (27/279) winter, 14%(40/28...

Four-hundred milk samples from half udders of 20 flocks of native breed goats were asepticallycollected. The samples were examined by California mastitis test (CMT). Twenty-one (5.25%) of 400 wereCMT-positive. The CMT-positive samples were then cultured and the following bacteria were isolated:Staphylococcus aureus in 3 (14.28%), CNS (coagulase-negative staphylococci) in 14 (66.66%), streptococ...
