Abstract

The aim of the study was to estimate the prevalence of subclinical mastitis (SCM) in lactating cows of Mymensingh and Lakshmipur sadar upazilas and to evaluate the efficacy of intramammary infusion in subclinical mastitis affected cows. A cross-sectional study was carried out on 78 smallholder dairy farms using a pretested questionnaire to collect data from June 2011 to May 2012. Milk samples from 139 lactating cows were screened for SCM by California Mastitis Test. A total of 72 cows was found positive for SCM and treated with the Neomastipra-JR5® intramammary infusion tube (Hipra, Spain). The overall prevalence of subclinical mastitis in lactating cows was 51.8%, of which 51.4% at Mymensingh sadar and 52.2% at Lakshmipur sadar upazilas. The prevalence of subclinical mastitis was significantly increased with age and parity of cows. In left hind quarter, the prevalence of subclinical mastitis was significantly higher (33.1%) than those of other quarters. The efficacy of intramammary infusion with Neomastipra-JR5® in lactating cows was 66.7%.
