Live animal evaluation is an important tool with which all students in animal agriculture should be familiar. Livestock procedures and breeders evaluate livestock for the correct time to market their animals, and order buyers and packers evaluate livestock for correctness of condition and red meat yield. The ability to effectively identify animals that meet the needs of the marketplace is an everyday occurrence for many people in animal agriculture.
A livestock producer must possess the proper understanding of live animal and carcass evaluation in order to remain competitive in today's changing marketplace. Furthermore, the producer should develop an ability to correlate these factors with the conformation or shape of the live animal. Ultrasound has proven to be an important tool to aid in selection; however, visual appraisal has the advantage of being faster and less expensive. Most market animals are bought and sold on the basis of visual estimation.
This website is designed to inform you about animal evaluation. The site is also a place to not only learn how to effectively identify differences in composition but also to practice your skills on animals and check actual carcass data.

The SDSU Youth Livestock Judging Camp instruction will cover live evaluation of the primary livestock species (cattle, sheep/goats and swine), as well as preparation and critique of oral reasons. Additionally, guest speakers on livestock nutrition and production will be available to all campers. Many teaching methods apply to this experience including lecture, demonstration, hands-on experience, one-on-one coaching and critiquing, along with question and answer sessions.
