DNA-Assisted Markers
The beef cattle industry could achieve quite a bit by using DNA-assisted markers to select for specific desired traits within the cattle. This would allow for an increase in the profits of producers due to the fact that they make the largest profit when cows with economically beneficial genes are bred. This type of DNA-based technology has such uses as predicting the genetic prospective for feed efficiency and tenderness. These come with a value stating how reliable these predictions may be. DNA-assisted markers also enable cattle to be traced back to the producer, as well as enabling the identification of the pedigree of calves. Nonetheless, in order to comprehend the advantages of such a technology, one needs a basic understanding of how DNA-assisted markers work.

A benefit of using this technology is it helps with selection for certain traits such as milk production, fertility, growth performance, disease resistance, and many more (Green).
Another benefit of DNA-assisted markers is it enables producers to make more precise choices for selection of economically important traits by giving them a new insight into the genes of their cattle. It also enables decisions to be made in regards to trait selections that may be costly or hard to measure when the cattle are young. This technology also increases revenue during the feedlot and backgrounding phases by enabling producers to select for a specific trait and determine early on whether or not the cattle will meet the specified criteria ("DNA-marker...Practice").
Aside from revenue and production benefits, DNA-assisted markers enable owners to trace the lineage of a particular animal to determine where it came from. This allows for the owner to provide information to the producer if the animal is unsatisfactory because DNA provides a means for traceback. This concept also allows for the identification of the parentage of a calf in an attempt to amplify breeding accuracy and assess male fertility (Green).
DNA-assisted markers do not present any real consequences by its use; on the contrary it presents a multitude of benefits. It benefits the beef cattle industry by enabling the identification of pedigree and parentage, leading to more accurate breeding, and allowing for the prediction of certain genetic potentials.
