This study aims to investigate calf mortality pattern in Gir breed. Research data were collected from the records of Gir herd, maintained at Kasturba Gandhi National Memorial Trust, Dairy Farm Kasturbagram Khandwa Road, Indore M.P., covering a period of 16 years (from 1994 to 2009). The period-wise distribution of calf mortality showed that highest mortality rate (18.9%) was recorded in period P4 (2006 to 2009) and the lowest (9.8%) in period P2 (1998 to 2001). Age-wise distribution of calf mortality showed that it was highest (5.4%) in 0 to 1 month age group in both sex. The lowest mortality was observed in 3 to 6 months of age group, which might be due to better management practices given to this age group. The mortality rate from 1 to 3 months and 6 to 12 months age group was also calculated and the values of mortality rate as 3.6 and 4.4% respectively. Sex-wise distribution of calf mortality indicates that out of total 208 male calves, 34 calves (15.9%) died, whereas, out of 196 female calves, a total of 27 calves (14.3%) were reported to be dead. Season-wise distribution showed that the highest calf mortality (5.7%) was determined in those calves born in the winter season. The overall mortality rates due to parity of the dam were 7.2, 4.5, 1.4 and 2.8% respectively for first, second, third and fourth calving. The highest mortality in Gir calves was recorded due to gastroenteritis (6.2%) followed by pneumonia (3.2%), insufficient or delayed colostrums feeding, handling causes and worm infestation (3.6%). Gastroenteritis as the prime cause of mortality could be synchronized with the results of high mortality rate in Gir calves during winter season in this investigation.
