Resumo: We analyzed average daily gain from weaning to yearling (ADG), yearling weight (YW), rib eye area, and subcutaneous fat thickness of 91 Angus, Hereford, Caracu, and Nellore cattle, and their crosses. The animals were split into two grazing groups: improved natural grassland (n = 47) and natural grassland (n = 44). The environment was found to influence all traits, and the highest measures of performance were observed in improved natural grassland. The genetic group x environment interaction was verified only for ADG and YW (P < 0.05). We found the best performance trait averages for crossbreeds of Bos taurus and Bos indicus. In addition, we found genetic x environment interaction effects in growing traits and Longissimus muscle area between the evaluated genotype groups. Finally, we found that between the evaluated genotype groups, subcutaneous adipose fat was not influenced by the environment.

Destes, 47 animais foram manejados em pastagem natural melhorada e 44 animais em campo natural do Bioma Pampa. Todas as características foram influenciadas pelo ambiente, sendo que os melhores desempenhos foram observados no ambiente constituído pela pastagem natural melhorada. A interação grupo genético x ambiente foi verificada no GMD e no PS (P < 0,05). As maiores médias das características analisadas pertenceram a produtos do cruzamento entre Bos taurus e Bos indicus. Houve efeito da interação genótipo x ambiente nas características de crescimento e de área do músculo longissimus entre os grupos genéticos avaliados (P < 0,05). A deposição de tecido adiposo subcutâneo não foi influenciada pelo ambiente de criação entre os grupos genéticos estudados.UEL2017-03-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2581810.5433/1679-0359.2017v38n1p481Semina: Ciências Agrárias; Vol. 38 No. 1 (2017); 481-490Semina: Ciências Agrárias; v. 38 n. 1 (2017); 481-4901679-03591676-546Xreponame:Semina.
