Ano: 2007 URL: http://purl.umn.edu/92862 An Economic Analysis of Genetic Information: Leptin Genotyping in Fed Cattle AgEcon DeVuyst, Eric A.; Bullinger, Jared R.; Bauer, Marc L.; Berg, Paul T.; Larson, Daniel M.. A polymorphism in the leptin gene is associated with fat deposition. Since fed cattle are often priced on a grid that considers yield and quality grades, fat deposition is an important factor in profitability. Using data from 590 crossbred steers and heifers, we simulate carcass traits to various days-on-feed and compute the associated profit under three price grids. Results indicate that leptin genotype does affect value by as much as $48 per head but has little impact on days-on-feed. Given current commercial testing fees of $40-$50 per sample, genotyping of feeder cattle appears to break even at best.

Ano: 2007 URL: http://purl.umn.edu/8644 AN ECONOMIC ANALYSIS OF GENETIC INFORMATION: LEPTIN GENOTYPING IN FED CATTLE AgEcon Bullinger, Jared R.; DeVuyst, Eric A.; Bauer, Marc L.; Berg, Paul T.; Larson, Daniel M.. The use of genetic knowledge is widespread in crop production but is just recently being utilized in livestock production. This study investigates the economic value to feedlots of a polymorphism in the bovine leptin gene. Previous studies indicate that this polymorphism is associated with fat deposition. Since fed cattle are often priced on a grid that considers both yield and quality grades, fat deposition is an important factor in the value and profitability of fed cattle. Using data from 590 crossbred steers and heifers, we estimate growth curves for relevant biological traits, both with and without genotypic information. Using the resulting functions, we then simulate carcass traits to various days-on-feed and compute the associated profit under three...
