In total, 234 numbers of cows housed in field conditions randomly screened for mastitis. Overall prevalence of subclinical mastitis (SCM) and clinical mastitis was found 32.48 % and 9.4 %. Statistical analysis of various epidemiological risk factors like body weight, age, milk yield, floor type, udder types, teat size, season, parity and stage of lactation showed a significant association in occurrence of mastitis in cows. Chi-square analysis resulted highest incidence of mastitis (36.73 %) in 5th parity. Rainy season showed an increased incidence with 62.24 % followed by 26.53 % in summer and 4.08 % in winter. Highest prevalence was seen in CBJ (70.41%) followed by HF (16.33 %) and lowest in Deshi non- descript breeds (13.27 %). Cows housed in earthen floor resulted maximum affections (48.98 %) followed by brick type (38.78 %) and lowest in concrete floor (12.24 %). Mastitis incidences were highest in cows with cup shaped udder (48.98 %), hind quarter (57.14 %) and right hind teats (40 %). The present study observed a significant increase of mastitis with older cows having more body weights.
