Phenotypic factors and genetic group on the selling price formation of beef calves sold in auctions at the Northern region of Paraná State, Brazil

Fatores fenotípicos e grupo genético na formação do preço final de bezerros de corte comercializados em leilões na região norte do Estado do Paraná, Brasil

The aim of this study is to estimate the effects of phenotypic traits on the final price of calves sold at auctions in the region of northern Paraná. Data were collected between April 2011 and April 2012 at 12 auctions, in which 197 lots were offered, totaling 4,289 animals. In this study, only the final prices charged when the deals were closed have been considered. Calves belonging to the British genetic group reached higher marketing value than zebu calves; the largest animals presented higher liquidity; buyers preferred more uniform lots, regardless of the sex of the animals.
