Abstract
Parentage testing is a tool that has been utilized within the cattle production industry for many years. This tool can be used for many purposes, but the most common reason is to determine if the farm’s top-notch bull is siring the desired number of calves. This is important information for the rancher to have because they need to know if their money is being well spent or if they need to reinvest in a different bull. The problem is that parentage testing is typically very expensive, making it difficult for the every-day rancher to afford it. The purpose of this paper is to look at the history of parentage testing- where it originated from, why it’s used, and its importance. It will also look at all the different methods one can use to accomplish parentage testing and their costs and benefits, including SNP analysis, which is the method of choice, used in some of USU’s ADVS research laboratories that offer parentage testing. The paper focuses in on SPN analysis and the materials and methods that are involved in it because this is currently the most accurate test. Ultimately, the goal of this literature review is to provide a central collection of information on parentage testing in cattle to demonstrate its great importance, and help researchers in the future figure out the best way to increase pedigree accuracy while still keeping costs low and affordable for the everyday rancher.
