Abstract: Identification of animal in livestock enterprise is of immense importance to draw conclusion of their status in production as well as performance. The present investigation was conducted at the Bull Mother Experimental Farm, College of Veterinary Science & A.H., Anjora, Durg on 80 Sahiwal cattle of different age groups. The age of animals ranged from 0 month to above 18 months. In 0-6 months, the time of appearance of white hairs were 49±1.83, 50.66±2.33, 48.75±3.94 and 55.25±1.75 days, respectively for 5, 7, 9 and 11 seconds of exposure time. In 6 to 12 months, the exposure time of 8, 11, 14 and 17 seconds using brass metal, the appearance of white hairs were 47.2±2.4, 49.75±1.75, 56.66±2.40 and 49.66±3.28 days, respectively. In 12 to 18 months, the times of appearance of white hairs were 59±1.00, 61±2.65, 55.5±6.54 and 62.5±2.50 days, respectively for 12, 15, 18 and 21 seconds of exposure time. In age group of above 18 months, the exposure time of 17, 20, 23 and 26 seconds using the brass metal, the time of appearance of white hairs were found to be 63±00, 47±00, 57.66±2.96 and 64±2.00 days, respectively.
