The objective of the present study was to evaluate non-linear models to describe Morada Nova sheep herds raised in the State of Bahia and, after defining the best suiting model, calculate the rate of absolute growth and evaluate the influence of environmental factors (sex and type of parturition) on the curve parameters. Weighting data from 40 sheep from birth up to 385 days of age were used. The non-linear models used were: Brody, Von Bertalanffy, Richards, Logistic and Gompertz. Von […]
