Comparative Analysis of Performance Traits of Different Dairy Cattle Reared in the Srinagar City of J&K

摘要

Breed structure of cattle in Jammu and Kashmir has changed over the last decades due to influx of different type of cattle from outside and implementation of various cattle developmental programmes. Presently, around 50% of the total cattle populationhas been upgraded into high yielding crossbred varieties, with highest proportion seen in the Srinagar District. A study was planned with the objective of studying the performance traits of these crossbred cows in the Srinagar District of J&K. Lactationyield, peak milk yield and daily milk yield was observed to be significantly higher in HFCB cows than JCB cows. Lactation length was significantly longer in JCB cows than HFCB cows. Gestation period and calving interval was longer in HFCB cows than JCBcows, whereas service period and age at first calving was longer in JCB cows than HFCB cows. Dry period was slightly higher for JCB cows than HFCB cows. Birth weight was significantly more in HFCB calves than JCB calves. It was concluded that both crossbreds performed well in the local conditions of Srinagar District of J&K.
