Abstract: To planning any breed improvement programme for dairy cattle it is pre-requisite to know the production and reproduction performance of that breed in detail. Sanchori cattle of Rajasthan have been recently registered by the ICAR-NBAGR. Data available on production and reproduction performance of this breed are scanty so present study was conducted on this breed. Survey for the present study was conducted in three districts of the Rajasthan state i.e. Jalore, Sirohi and Barmer. A total of 152 farmers, 158 gaushalas from 34 blocks were interviewed to record information on dairy performance traits using structured questionnaire. Fat and SNF% were recorded manually from randomly collected 566 Sanchori cattle milk samples using milk analyzer. First lactation daily milk yield, peak milk yield, lactation milk yield, lactation length, fat% and SNF% were reported as 6.07±0.56 kg, 11.36±0.35 kg, 262.85±3.54 days, 1521.42±53.68 kg, 4.04±0.10% and 9.20±0.05%, respectively. Overall lactation daily milk yield, peak milk yield, lactation milk yield, lactation length, fat% and SNF% were reported as 5.93±0.11 kg, 11.81±0.09 kg, 283.61±1.10 days, 1755.41±13.42 kg, 4.07±0.02% and 9.07±0.01%, respectively. Reproductive performance traits i.e. age at first oestrus, oestrous cycle duration, oestrus duration, age at first mating, age at first calving, service period and calving interval were reported as 37.40±0.2 months, 21.09±0.01 days, 24.45±0.06 hrs, 42.58±0.24 months, 52.02±0.24 months, 118.35±0.88 days and 14.13±0.03 months, respectively.
