Abstract:

The present study was carried out using data of first lactation records of 513 Gir cows sired by 75 bulls spread over a period of 34 years (1981 to 2014), maintained at Cattle Breeding Farm, Junagadh Agricultural University, Junagadh. Analysis was carried out by least squares analysis method described by Harvey (1966) and followed by Duncan’s multiple range test. The overall least squares means for first lactation 300 day or less milk yield (FL300DMY) was 1506.36 ± 40.10 kg. Season of calving had non-significant effect on FL300DMY. Period of calving had highly significant (P<0.01) effect on FL300DMY. Age at first calving had non-significant influence on FL300DMY, while calf birth weight had significant (P<0.05) effect on FL300DMY.


Keywords: Age at first calving, FL300DMY, Calf birth weight and Gir cow
