Various milking and reproductive performances were analyzed. The effects of concentrate feed were found significant on age at weaning AW (p<0.001) age at first heat (AFH) (P<0.05) age at first conception (AFH) (P<0.001) No. of services per conception (P<0.05), age at first calving (P<0.001) post partum heat period (PPHP) (P<0.001), calving interval (Cl) (P<0.001), daily milk yield (p<0.05) and lactation length LL (P<0.001). The effects of management level were significant on AW (P<0.001), PPHP (P<0.01), CI (P<0.001) and daily milk yield (P<0.05). The overall mean values were 245.80± 3.80 days for AW, 35.30±0.40 months for AFH, 37.20± 0.70 monthly for conception, 46.20±0.40 monthly for AF calving, 1.30±0.10 for no. of services for conception, 182.90± 4.80 days for PPHP, 15.50±0.20 months for CI, 2.50±0.30 kg for daily milk yield and 250.60±4.50 days for lactation length.
