The objective of this study was to estimate the (co)variance components and genetic parameters for milk yield (MY), calving-to-conception interval (CCI), number of services per conception (NSC) and calving interval (CI) of Honduran Holstein cows, by tting a bivariate animal model using Maximum Restricted Likelihood procedures. Model included the xed effects of, calving number, the contemporary calving group (farm-season-year of calving and the cow age as covariate). The estimated means and standard deviations for MY, CCI, NSC and CI were, 5098.60 ± 1564.32 kg, 168.27 ± 104.71 days, 2.46 ± 1.69 services, and 448.73 ± 109.16 days, respectively; and their estimated heritabilities were 0.21 ± 0.05, 0.03 ± 0.028, 0.02 ± 0.024 and 0.06 ± 0.04, respectively. The genetic correlations between MY305 and CCI, NSC and CI were positive and antagonist, with values of 0.64 ± 0.52, 0.99 ± 0.56, and 0.32 ± 0.24 respectively. Even though moderate to low heritability was estimated for MY, important genetic considering the systematic selection of MY; however, with a reduction in reproductive e ciency, if considered as the only selection criterion. By including reproductive traits and considering permanent environment effects into the breeding program, will yield a slow, but constant and permanent improvement over time.
