Abstract
This study evaluated different crosses for sustainable beef production in the Meio-Norte, Brazil. Thirty-four cattle [seven Curraleiro Pé-duro (CPD), six Nellore (NEL), seven , seven , and seven ] were evaluated on natural pastures in the states of Piauí and Maranhão. The animals were weighed at birth (BW); weaning (WW); 12 (W12), 18 (W18), and 24 months (W24); and slaughter (SW). The morphometric measurements of rump height (RH), withers height (WH), body length (BW), and heart girth (HG) were [...]

Summary
Sustainable beef production is the major challenge of livestock farming. In biomes with a low productive potential (native-pasture areas), farmers seek alternatives to reduce slaughter age and produce high-quality meat.In Brazil, beef cattle are commonly reared in tropical pastures. Sustainable beef production is the major challenge of livestock farming. In biomes with a low productive potential (native-pasture areas), farmers seek alternatives to reduce slaughter age and produce high-quality meat. In Brazil, beef cattle are commonly reared in tropical pastures. The Central-West and North regions concentrate the largest herds and the largest livestock raising area in the country. The rational exploitation of non-agricultural areas can increase meat production and reduce deforestation. The interaction between animal genotype and rearing environment must be understood. In this context, the use of adapted local breeds (e.g., Curraleiro Pé-Duro) is an interesting practice
