Abstract
The present investigation was undertaken to access first lactation total milk yield, first lactation length, productive life, herd life and total life. Breeding information were used from the history sheet registers and herd inventory registers of Hariana cattle maintained at DUVASU farm, Mathura and Babugarh farm, Hapur. The data of productive animals with date of calving from 1966 to 2018 and date of birth from 1962 to 2013 were collected for the study. The overall averages for FLTMY, FLL, PL, HL and TL were estimated as 971.2±16.9 litres, 328.2±3.8 days, 2019.1±42.1 days, 2251.8±43.9 days and 3915.7±44.2 days, respectively. The overall least-squares mean of 961.3±24.1 litres, 331.6±5.9 days, 2285.2±64.9 days, 2489.9±69.1 days and 4219.4±70.0 days was observed respectively for the above traits. Season of calving had significant effect on first lactation length and period of calving had significant effect on first lactation total milk. Farm, period of birth and AFC age group had significant effect on PL, HL and TL of Hariana cattle. The heritability for FLTMY and FLL was moderate to high in Hariana cattle.
