Modeling of crossbred cattle growth, comparison between cubic and piecewise random regression models
“Modeling of crossbred cattle growth, comparison between cubic and piecewise random regression models”, vol. 10, pp. 2230-2244, 2011.
, Two analyses, cubic and piecewise random regression, were conducted to model growth of crossbred cattle from birth to about two years of age, investigating the ability of a piecewise procedure to fit growth traits without the complications of the cubic model. During a four-year period (1994-1997) of the Australian “Southern Crossbreeding Project”, mature Hereford cows (N = 581) were mated to 97 sires of Angus, Belgian Blue, Hereford, Jersey, Limousin, South Devon, and Wagyu breeds, resulting in 1141 steers and heifers born over four years.
