Abstract: The experiment was conducted with the duration of six months at ABIS (Aamir Bahadur Sultan Ali) Buffalo Dairy Farm, Gormara, Rajnandgaon (Chhattisgarh) to investigate the variability of skin thickness in relation to milk production. A total of 120 milking Murrah buffaloes were selected for the experiment. The Murrah buffaloes were selected in a range of first to sixth parity and each parity containing 20 buffaloes. All the selected Murrah buffaloes of the present investigation were kept under similar housing system i.e. loose housing system with one shelter along one side of the paddock and provided green fodder and total mix ration as per their requirement. Drinking water was made available ad lib to whole day. The milking was done by milking machine in milk parlour in morning and evening. Daily milk yield and total milk yield were recorded from the records. The correlation between skin thickness of neck, chest, abdomen, rump, hind quarter, udder and flank and total milk yield were -0.377, -0.498, -0.355, -0.282, -0.207, 0.073 and -0.072 respectively. Correlation between lactation length and different site of skin thickness was found significantly positive. However, negative correlation was observed for daily milk yield. On the other hand, regression coefficient of skin thickness and milk yield indicated that an increase in skin thickness of neck, chest, rump and hind quarter could decrease in average total milk.
