Thanks, it hadn't occurred to me to pull the hairs out.I use Neogen. They started using an electronic order system a year or two ago. The process is not always intuitive, but it works. Another option is UCDavis Veterinary Genetics Lab, but they charge $25.
Either one can use a hair sample of about 30 hairs. I use clean pliers and pull hair from the end of the tail (switch). The hairs should have root bulbs, otherwise they are no good. Sometimes I get pieces of dead skin and include that as well; there's DNA in that too.
Hair samples is how we have done it in the past in going through the Angus Association. With your calf being out of a Sim bull, I’d reckon the Simmental Association or possibly direct to a company would be the routes to go through.Thanks, it hadn't occurred to me to pull the hairs out.
