Abstract

Data on production (lactation milk yield, lactation length, dry period) and reproduction performance traits (service period and calving interval) of Rathi cattle maintained at Livestock Research Station (LRS) Nohar, District Hanumangarh (Rajasthan) during the period 1979–2002 were analyzed to study the effect of non-genetic factors on these traits. The overall least square means for lactation milk yield (LMY), lactation length (LL), dry period (DP), service period (SP) and calving interval (CI) were 1589.49±75.55 kg, 267.09±08.04 days 155.28±09.65 days, 153.03±22.80 days and 427.44± 12.30 days, respectively. The analysis of variance revealed that effects of parity, season and period on the overall lactations production and reproduction traits was significant (P<0.01) except the effects of parity and season on LMY, season on SP and effect of parity and periods on DP.
