Abstract:
The records of 123 Surti buffaloes with 240 lactations sired by 44 sires maintained at Livestock Research Station, Navania, Vallabhnagar (Udaipur) born from 2006 to 2020 were collected to estimate the effect of non-genetic factors viz., period, season and parity on calving interval. The average calving interval in Surti buffaloes was found to be 501.06±10.90 days. The analysis of variance revealed the highly significant effect of period and season of calving but a non-significant effect of parity on calving interval. Calving interval showed declined trend from 2006-2010 (Period 1^st) to 2016-2020 (Period 3^rd) indicates improvement of breeding and management practices over the period in the farm.
