Genetic association of productive and reproductive traits with stayability in Nellore cattle: analysis using Bayesian models

E. C. A. Rizzo, Neto, F. R. A., Diaz, I. D. P. S., Dias, M. M., Costa, R. B., Ventura, H. T., Oliveira, H. N., and Falcão, A. J. S., Genetic association of productive and reproductive traits with stayability in Nellore cattle: analysis using Bayesian models, vol. 14, pp. 14956-14966, 2015.

We evaluated the genetic association of growth traits [weight adjusted to 205 days of age (W205), 365 days of age (W365), and 550 days of age (W550); weight gain between 205 days of age and 365 days of age (WG1) and between 365 days of age and 550 days of age (WG2)] and reproductive traits [age at first calving (AFC); first calving interval (FCI)] with stayability in the herd (STAY), using Bayesian inference in linear and threshold models. We defined STAY as the probability of a cow calving three or more times before the age of 76 months, given that she had calved at least once.
