“…Similarly to the results of Christofari et al (2010) and Lopes et al (2017), the average weight of the lot was the main variable responsible for the selling price. With increasing production costs, rearing animals that were already closer to slaughter weight was an important factor for the profitability of livestock activity.…”

“…This decline was due to the impossibility of purchasing a heavy animal with high added value. Christofari et al (2010) suggested that the buyer can use the strategy of acquiring lighter calves and purchase more units at a lower price, especially when the price per kg for calves is higher than that of steers for fattening. The decline is higher for males, as heavy females tend to be used in breeding (Schroeder et al, 1988;Dhuyvetter and Schroeder, 1999;Smith et al, 2000).…”

This study was performed to determine and quantify the inherent auction factors that affect the selling price of beef calves (weanlings -from six to nine months old). Data on the selling price, location and month of the auction, genetic group, lot size live weight, and sex of animals were collected in 148 auctions from January 2004 to December 2014. A total of 4,312 lots corresponding to 48,588 calves were classified into seven genetic groups according to their phenotypic characteristics. The values were deflated using the General Price index (IGP-DI) inflation index and met the parametric assumptions. The selling price was standardized by the yearly median, assuming that its value corresponds to 100%, and the other values varied in their function. Path analysis quantified the direct and indirect effects of the variables taken as explanatory of the selling price, followed by regression analysis and Tukey test. Overall, the direct effect of the average weight was the highest (0.7), followed by sex (0.38). The smallest direct effect was the genetic group (−0.075). There was a growing exponential relationship between average weight of the lot and selling price and a decreasing ratio between price per kilo and the average weight of the lot (−0.0003 percentage points per kilogram). Males were generally 15.7% more valued than females. The British × Zebuine crossbreed was the most valued breed, followed by the British breed (8.9 and 3.6%, respectively). The highest premium was in November, followed by February (9.57 and 8.84%, respectively, compared with median year). The selling price increases linearly by 0.3284 percentage points for each additional animal in the lot. The average weight of the lot was found to be the most important variable in the formation of the selling price, followed by the sex of the animals. How to cite: Danielce, M.

“…The price of live beef cattle is the main variable that determines the price of other categories of animals in beef cattle. Consequently, when the live price of beef cattle is low, in general, farmers have fewer incentives to purchase animals for replacement, which will result in a reduction in its price (Christofari et al, 2010). In the state of Mato Grosso, the correlation between the price of live beef cattle and calves was 0.89 (Agrolink, 2015), which was nearly equivalent in our study, 0.90 (P<0.001) (Figure 1).…”

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

et al. 2016

-The objective of this study was to investigate the effects of genetic group and calf sex on selling prices in auctions in the state of Santa Catarina (SC), Brazil. We evaluated 33,143 animals, representing 3,587 lots in 47 auctions from 2009 to 2014. The calves were classified according to genetic groups: British breed or crossbreed (BX); Continental breed or crossbreed (CX); Zebu breed or crossbreed (ZC); British and Continental crossbreed (BC); and Bos taurus and Bos indicus crossbreed (TI). The lots were composed of male and female calves. The years presenting low and high changes in the price of calves were similar to the variation in the price of beef cattle and, in 2014, the calf price reached its highest value (R$5.36). Male calves were sold at prices higher than female calves (average 7.8%), but this difference was driven by year of analysis, in which the closest approach occurred during periods of reduction in the price of live cattle in SC (2012 and 2013). Calves of genetic groups ZX and TI received, on average, lower prices (R$4.49 and R$4.64, respectively) compared with the other groups. In 2013, males from the BX group had greater variation in price compared with CX (3.9%) and BC (5.7%). On the other hand, female heifers from the BX group received higher average prices in 2011 compared with the CX, BC, IT, and ZX groups (8.1, 8.5, 14.7, and 16.5%, respectively). Recently, female British heifers have had a greater appreciation in auctions held in SC, possibly for their reproductive performance potential of beef cows. Thus, sex and different genetic groups are factors that impact the selling price of calves in the SC region.

“…Several studies have shown that a number of factors affect the price of animals along the marketing process, such as physical, genetic and nutritional characteristics, and handling and market conditions (SULLIVAN & LINTON, 1981;SCHROEDER et al, 1988;SARTWELLE et al, 1996;TROXEL & BARHAM, 2007;LEUPP et al, 2008;CHRISTOFARI et al, 2009;CHRISTOFARI et al, 2010;SCHULZ et al, 2010 specialized breeding and marketing of animals with the characteristics required by buyers are strategies that can increase both the production and the productivity of a herd (TURNER et al, 1992;KASSIE et al, 2010), thus making the activity more profi table (CLEERE & BOLEMAN, 2000).…”
