D. J. A. Santos, Peixoto, M. G. C. D., Borquis, R. R. Aspilcueta, Verneque, R. S., Panetto, J. C. C., and Tonhati, H., Comparison of random regression models to estimate genetic parameters for milk production in Guzerat (Bos indicus) cows, vol. 12, pp. 143-153, 2013.

Random regression models have been widely used to estimate genetic parameters that influence milk production in Bos taurus breeds, and more recently in B. indicus breeds. With the aim of finding appropriate random regression model to analyze milk yield, different parametric functions were compared, applied to 20,524 test-day milk yield records of 2816 first-lactation Guzerat (B. indicus) cows in Brazilian herds.
