First time in India economic losses due to outbreak (OB) of Johne’s disease (JD) in a Holstein Frisian (H/F) dairy farm were recorded. OB of JD was suspected by clinical signs [loss in body condition, sharp drop in milk yield (30 to 2 litres/day), increase in cases of infertility, mortality etc.] and necropsy findings. JD was confirmed by screening of 30.0% cows by microscopy (68.5%), serum ELISA (92.3%), milk ELISA (60.8%) and blood PCR (35.7%). Losses due to stress culling, mortality and reduced productivity (infertility, stunted growth) were quantified. Growing heifers exhibited weakness, stunting and delayed first heat. Losses due to delayed breeding, reduced fertility and repeat breeding were Rs 1,63,800.0 in 180 days. Losses due to mortality and culling during JD OB were Rs 1,05,000.0 and Rs. 1,67,000.0, respectively. Losses due to reduced milk yield were Rs 54,442.5 /cow/lactation. Total losses at the farm were very high (Rs. 16,87,977.5), since H/F cows being high yielding were at higher risk and suffered with JD outbreak. Low per animal productivity of domestic livestock indicated necessity to initiate JD control programs at the National level.
