An on-farm study was conducted during different season at farmers field in Samastipur district of Bihar to assess the effect of dry cow therapy as an intervention for control of mastitis in dairy herd. Twenty one crossbred cows were selected at dry-off and distributed in three group with 7 animals each. The experimental treatment groups were T1 (Control- No dry cow therapy), T2: dry cow therapy with Spectramast D C at last day of milking) and group: T3dry cow therapy with Spectramast D C along with application of Intavita H 5ml I/M. Daily milk yield was recorded for 30 days after 15 days of post-partum to find out the effect of dry cow therapy on milk production. The finding of the study showed that dry cow therapy in combination with Intavita H (T3) or alone dry cow therapy were effective protocol to control mastitis with reduced mastitis cases as compared to T1(control). However, dry cow therapy in combination with Intavita H (T3) was more effective against control of mastitis. The milk quantity and quality were also improved with treatment of dry cow therapy.
