ABSTRACT

A data on 2040 records of halfbreds (FG and JG) and three breed (FJG, JFG and BFG) Gir
crosses were collected and analysed by least-squares method. The genetic group, period and seasonof calving, parity, age and weight at first calving were considered as sources of variation. The overall least-squares means for calving interval of first five lactations and their pooled were
419.60±4.38, 401.89±7.02, 401.32±5.82, 400.62±8.16, 387.33±12.58 and 403.45±3.45
days, respectively. The calving interval of first five lactations were non-significantly affected by all
the sources of variation except genetic group effect (P
