Abstract:

Subclinical mastitis, without obvious clinical signs of disease, accounts for high economic losses in dairy farms. Cows with subclinical mastitis experience reduction in milk yield due to high somatic cell count and represent possible sources of infection for other cows. The present study was conducted to assess the prevalence of subclinical mastitis among lactating dairy cows in organized farms and to investigate the etiology of the condition. A total of 139 lactating cows belonging to three organized farms in Thrissur district were screened for subclinical mastitis using California mastitis test, electrical conductivity and somatic cell count(SCC). Sub clinical mastitis was detected in 84.17 per cent animals. California mastitis test was found to be useful for screening for subclinical mastitis under field condition and correlates well with SCC, where as electrical conductivity was not found to be a sensitive screening test in the present study. Staphylococcus aureus was identified as the major pathogen followed by various coagulase negative staphylococci, Streptococcus spp., Micrococcus spp. and Pseudomonas spp. Enrofloxacin and Cefaperozone were found to be the most sensitive antibiotics against the isolates from subclinical mastitis. The findings of the present study stress the need for implementation of udder health management programmes to control subclinical mastitis in dairy cows and to improve their production potential.
