- Analysis of growth curves in different lineages of Caipira broiler type Caroliny Costa Araújo Kênia Ferreira Rodrigues Roberta Gomes Marçal Vieira Vaz Ana Carolina Müller Conti Aline Ferreira Amorim Carla Fonseca Alves Campos Agrociencias age birds weight lineage statistical model The objective of this work was to identify, by means of different statistical criteria the ideal nonlinear regression model to describe the growth curve of three lineages of caipira broiler for meat production. A total of 90 birds were used, being 30 birds from each of the following lineages: Pescoço Pelado, Carijó and Pesadão Vermelho. The individual body weight of broilers (1, 7, 14, 21,28, 35, 42, 49, 56, 63, 70, 77, 84 and 91 days of age) was collected weekly for determination of growth curves by means of Models von Bertalanffy, Gompertz, Logistic, Richards and Brody. The parameters of Brody model did not converge to the weight of strains. The model that better adjusted to the data was Logistic. 2018 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303158407013 https://www.redalyc.org/journal/3031/303158407013/ https://www.redalyc.org/journal/3031/303158407013/html/ https://www.redalyc.org/journal/3031/303158407013/303158407013.epub https://www.redalyc.org/journal/3031/303158407013/movil 10.4025/actascianimsci.v40i1.38806 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
