| 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. |
