Source and Age Verified Lots of Beef Calves Sold for a Premium Via Summer Video Auction from 2010 through 2017

The objective was to quantify the effect of source and age verification status on the sale price of lots of beef calves sold via summer video auctions from 2010 through 2017 while adjusting for all other factors that significantly influenced price. Data analyzed were collected from 61 summer livestock video auctions from 2010 through 2017. There were 36,570 lots of beef calves used in the analyses. All lot characteristics that could be accurately quantified or categorized were used to develop a multiple regression model that evaluated the effects of independent factors on sale price each year using a backwards selection procedure. A value of P < 0.05 was used to maintain a factor in the final model. In each year, a model was developed to quantify the effects of all factors describing lots of beef calves that significantly affected sale price. The seller of calves consigned to sell through the video sale must complete and sign an affidavit verifying that the calves were enrolled in a USDA approved Source and Age Verification program and had program compliant ear tags.
