Value of Genetic Information for Beef Cattle at the Feedlot Stage
نویسندگان
چکیده
We estimate the value of using information from genetic marker panels for seven economically-relevant feedlot cattle traits. At the current cost of genetic testing it would not pay to sort cattle by optimal days-on-feed, but it could pay to use the genetic tests for breeding cattle selection.

A bioeconomic model for comparing beef cattle genotypes at their optimal economic slaughter end point.
A bioeconomic model of a feedlot was developed for the comparison of beef cattle genotypes under specified management and marketing conditions. The optimization behavior of commercial feedlot managers is incorporated into the model using optimum economic rotation theory. The days spent in the feedlot (rotation) by a group of animals are derived using this theory so as to maximize an objective f...
متن کاملWhere in the beef-cattle supply chain might DNA tests generate value?
DNA information has the potential to generate value for each sector of the beef-cattle industry. The value distribution among sectors (breeding, commercial, feedlot, processing) will differ depending on marketing. The more descendants an animal produces, themore valuable each unit of genetic improvement becomes. Therefore, the value of using DNA testing to increase the accuracy of selection and...
متن کاملValue of Genetic Information for Management and Selection of Feedlot Cattle
We estimate the value of using information from genetic marker panels for seven economically relevant feedlot cattle traits. The values of using genetic information to sort cattle by optimal days-on-feed are less than $1/head for each of the traits evaluated. However, the values associated with using genetic information to select cattle for placement are as much as $38/head. The most economical...

متن کاملTemporal prevalence of antimicrobial resistance in Campylobacter spp. from beef cattle in Alberta feedlots.
Antimicrobial resistance (AMR) was temporally assessed in campylobacters isolated from beef cattle (7,738 fecal samples from 2,622 animals) in four commercial feedlots in Alberta. All calves were administered chlortetracycline and oxytetracycline in feed, and a majority of the animals (93%) were injected with long-acting oxytetracycline upon arrival at the feedlot. Fecal samples from individual...
