Effect of post-milking teat dip on subclinical mastitis in crossbred cows

The prevalence of subclinical mastitis is currently increasing in our country and adversely affecting dairy farmers’ economies. To note down the effect of post-milking teat dip on subclinical mastitis, 30 crossbred cows were randomly divided into two groups based on parity and age viz., T₀ (n=15, farmer's practices - washing of milker hand and udder with water) and T₁ (n=15, with farmer's practices along with the use of post-milk teat dip of 3.5% Lactic acid) during the experimental trial of 30 days. By use of post-milk teat dip, the CMT and SCC positive cases were decreased by 71.4 % and 72.2 % respectively in T₁. The SCC and pH of milk were significantly (p< 0.05) reduced however, milk yield was significantly (p< 0.05) increased by 6.7 % in T₁ compared to T₀ on 28^th day. The use of post-milk teat dip is cost-effective in terms of economics and recommended for dairy farmers to prevent subclinical mastitis.
