Vaccination is a critical intervention in the management of productive animals, but it is often associated
with a transient reduction in milk production. The current study aimed to assess the extent of milk
production loss in dairy animals following Foot and Mouth Disease (FMD), Hemorrhagic Septicemia and
Black Quarter (HS and BQ), Theileriosis and Infectious Bovine Rhinotracheitis (IBR) vaccinations. The
milk production data was collected 15 days before and after vaccination from 2018 to 2020 during different
vaccination program. We found a significant (p<0.01; p<0.05) decrease in fortnightly total milk yield per
animal and average milk yield per animal per day was observed in different parities and lactation stages
following vaccination compared to pre-vaccination levels. Among the vaccinated animals, Sahiwal cows
exhibited varying responses to vaccinat.. View More»
