The metabolic interpretation of the von Bertalanffy growth rate

open access: yesEcological Modelling
The von Bertalanffy Growth Rate (vBGR) has a clear physiological interpretation and is proportional to the volume-specific somatic maintenance rate. This links high maintenance to fast growth, as is exploited by the waste-to-hurry strategists, which experience high food availability peaks during short periods.

Accuracy of goodness-of-fit criteria for nonlinear regression: a study via Monte Carlo simulation

open access: yesActa Scientiarum: Technology
Nonlinear regression models are widespread in the literature, and one of their main applications is in the study of sigmoidal growth curves. There are several models for this purpose, and the most used are the logistic, Gompertz, von Bertalanffy, and ...

Estimation of growth in intact grazing Holstein steers

open access: yesRevista Colombiana de Ciencias Pecuarias, 2013
Summary Background: animal growth does not follow a linear pattern. Accordingly, fitted non-linear models are used to analyze the relationship between growth rate and age. Objective: to assess the ability of several mathematical models (Gompertz, Brody,
