Abstract
Analisaram-se os efeitos da média de peso vivo de 1.880 lotes de bezerros comercializados em 13 leilões, no Rio Grande do Sul, sobre o valor de venda final por unidade de peso, e caracterizou-se a frequência dos lotes conforme a classe de peso durante as estações de outono e primavera, no período de 2004 a 2006. Os dados foram corrigidos pelo índice geral de preços - disponibilidade interna e analisados por meio de histogramas de frequência e análises de regressão e correlação. O peso vivo influenciou o preço dos bezerros, e a magnitude do efeito foi maior nos anos de grande demanda. Observou-se correlação negativa entre preço e peso dos bezerros na primavera, reflexo da oferta de animais mais pesados, devido aos efeitos de estação do ano ou à maior idade dos bezerros, comparados aos ofertados no outono. Não se observou maior liquidez dos bezerros comercializados no outono em relação aos da primavera. A conjuntura da cadeia da carne bovina e os preços de outras categorias têm grande relação com os preços pagos. A aquisição de animais de menor ou maior peso na ocasião da transação comercial pode auxiliar na redução dos custos que a reposição representa na produção.
The effects of the live weight of 1,880 lots of calves marketed in 13 auctions in the State of Rio Grande do Sul, Brazil, on the value of final sale per unit of weight were evaluated, as well as the frequency of the lots according to the weight class during the autumn and spring seasons, in the period from 2004 to 2006, was characterized. The data were analyzed by frequency histograms, regression, and correlation analyses. The live weight is one of the characteristics that influenced the price of the calves; however, the magnitude of the effect was higher in years of great demand. A negative correlation was observed between price and weight of the calves in spring, which were results of the offer of heavier animals, due to the season effects or the oldest age of the calves compared to those presented in the autumn. The chain conjuncture of the bovine meat and the prices of other categories have great relation with the prices paid. Therefore, the acquisition of highter or heavier animals in the occasion of the business deal may help in the reduction of the costs represented by the replacement in the production.
