AB  - The present study was conducted on 1,002 reproductive records of 430 Jersey 
      crossbred cattle, descended from 57 sires and 198 dams, maintained at the Eastern 
      Regional Station of ICAR-National Dairy Research Institute, Kalyani, Nadia, West 
      Bengal, India to investigate the influence of direct genetic, maternal genetic 
      and maternal permanent environmental effect on three most important reproductive 
      traits viz., number of service per conception (NSPC), days open (DO) and calving 
      interval (CI) of Jersey crossbred cattle. Six single-trait animal models 
      (including or excluding maternal genetic or permanent environmental effects) were 
      fitted to analyse these traits, and the best model was chosen after testing the 
      significant increase in the log-likelihood values when additional parameters were 
      added in the model. Direct heritability estimates for NSPC, DO and CI from the 
      best model were 0.10, 0.14 and 0.20, respectively. The maternal permanent 
      environmental (c(2) ) effects on reproductive traits accounted for almost 
      negligible fraction of the total phenotypic variance in this study. The maternal 
      genetic effects (m(2) ) also contributed very little (0%-3%) to the total 
      phenotypic variance except for CI where it was important and accounted for 20% of 
      phenotypic variance. A significantly large negative genetic correlation was 
      observed between direct and maternal genetic effects for all traits, suggesting 
      the presence of antagonistic relationship between dam's direct additive component 
      and daughter's additive genetic component. Results suggest that both direct and 
      maternal effects were important only for CI but not for other traits. Therefore, 
      both direct additive effects and maternal genetic effect need to be considered 
      for improving this trait by selection.
