Abstract
The reproductive performance of Gaolao cattle were studied at different location in the breeding tract. The idea behind the collection of data in breeding tract of Gaolao cattle from the farmers and breeder heard of Gaolao rather than on the organized farm to obtain the real picture of reproductive performance of breed in the breeding tract. In present finding the overall least square means for age at puberty (AP) of Gaolao cattle was recorded as 1202.27 + 13.01 days. The effect of block was found non-significant on age at puberty (AP) whereas, the effect of colour was found significant. The overall least square means for age at first calving (AFC) of Gaolao cattle was recorded as1610.12 + 12.68 days. The effect of block and colour was found non-significant on age at first calving (AFC) of Gaolao cattle. The overall least square mean for service period (SP) of Gaolao cattle was recorded as 145.46 + 1.52 days. The effect of block and colour was found non-significant on service period (SP) of Gaolao cattle. The overall least square mean for gestation period (GP) of Gaolao cattle was recorded as 281.92 + 0.60 days. The effect of block and colour was found non-significant on gestation period (GP) of Gaolao cattle. The overall least square mean for inter calving period (ICP) of Gaolao cattle was recorded as 427.17 + 1.44 days. The effect of block and colour was found non-significant on inter calving period (ICP) of Gaolao cattle. The improvement in reproductive characteristics of indigenous breed has become essential to make economically viable dairy animal.
