Factors affecting the selling prices of calves in auctions in Santa Catarina State, Brazil

“…Our study showed that the higher prices of M calves compared with F were also in agreement with Koetz Junior et al (2014), who demonstrated that M are on average 11.5% more valuable than F calves marketed in the state of Paraná. Similar results were found in auctions studied by Crespo et al (2006) in Uruguay and by Troxel and Barham (2007) end of the analysis period.…”

“…In agreement, studies reported that higher valuations are reached using particular genetic groups (Halfman et al, 2009;McHugh et al, 2010;Koetz Junior et al, 2014). However, Barham and Troxel (2007) reported that no specific breed or breed type was marketed for higher prices and the superiority of a given group is dependent on the region where the sale occurred and the future prices for the coming years.…”

“…Christofari et al (2008) found a predominant supply of lots constituted by calves crossed with British and Zebu breeds, which exceeded 60.0% of lots offered and may be associated with the growth of synthetic breeds in Rio Grande do Sul. In Paraná, auctions from 2012 to 2013 showed that the supply of Nelore calves was similar to calves crossed with taurine breeds (48.2 and 51.8%, respectively) (Koetz Junior et al, 2014). This study shows that in SC, the largest supply of animals belongs to the BX and CX groups, which is in agreement with studies performed in Rio Grande do Sul and Paraná, where there is a large number of Bos taurus calves offered in the southern regions compared with other regions of Brazil.…”

“…Thus, consumers began to demand quality meat and finishing producers are willing to pay more for quality animals In the state of Rio Grande do Sul, Christofari et al (2008) observed that there is a preference for synthetic and European breeds, demonstrated by increased liquidity of selling these groups when compared with zebu crosses and mixed breeds; this was similarly observed in our study in SC. In the state of Paraná, zebu calves were sold at a price 5.5% lower compared with taurine calves (Koetz Junior et al, 2014). Reports performed in Arkansas (USA) compared two years of commercialization of M and F calves confined in the region (2000 and 2005) and showed that Angus × Hereford and Angus × Charolais crosses had an increase in the price in 2005 compared with 2000, while lots of Brahman, Charolais, Limousin, and Charolais × Limousin decreased the market selling prices .…”

“…The price of a cow/calf is affected by condition factors of supply and demand, including physical characteristics (e.g., sex, breed, live weight, frame, and handling) and market conditions (e.g., lot size, number and uniformity of animals in the lot, feed, and future prices) (Christofari et al, 2009;Willians et al, 2012;Koetz Junior et al, 2014). However, many of these factors are very subjective and producers believe that feeder cattle prices are inconsistent.…”
