In order to establish future plan for dairy development different species of dairy animals were studied in high altitude region of Kashmir Himalayas to know the details about their productive performance. A total of 122 dairy animals were selected from Gurez valley which is situated at an altitude between 2460 to 3900 meters above msl and the average temperature varies between 25º to -20º during summer and winters respectively. Data on the productive and reproductive performance of 57 Local cows, 23 Crossbred cows, 22 Dzomo/Dzho and 20 Yaks were collected by questioning the owners about each animal specifically during 2015. Significant difference were found within the age at first calving, milk yield (p<0.01), lactation length (p<0.01), dry period (p<0.01), calving interval (p<0.01) and lactation yield (p<0.01) of different species of dairy animals in Gurez Valley of Kashmir Himalayas. The average age at first calving of local cows was found 40.11± 3.68 months, crossbreds 35.0 ± 2.00 months, Dzomo 45.0 ± 4.55 and Yak 48.37 ± 2.00 months respectively, with significant difference (p<0.01) .The mean milk yield of Local cows, Crossbred cows, Dzomo and Yak were found to be 2.66 ± 0.45, 6.28 ± 2.29, 2.58 ± 0.81 and 1.90 ± 0.60 litres/day respectively. The highest lactation length of 342.54 ± 25.33 days was recorded in local cows and the lowest of 295.34 ± 28.43 days was recorded in Yak. The lowest dry period of 129.12 ± 12.75 days was recorded in Crossbred cows and the highest of 229.69 ± 29.62 days was recorded in Yak. The lowest calving interval of 438.34 ± 13.55 days was found in Crossbred cows and the highest of 503.03 ± 63.22 days was found in Yak.
