Results regarding, growth performance of Gir cattle showed lower values of age at puberty and age at first calving in present study. Birth weight, age at puberty, weight at puberty, age at first calving and growth rate up to puberty has not shown any seasonal variation. Quite satisfactory values in case of service period, number of services, calving interval, dry period, breeding has been shown efficiency reproductive and productive.
