Once again I would like to share some of the tidbits of information I hope the youth gained thanks to participating in the livestock skill-a-thons this year. The livestock skill-a-thon allows the youth a chance to test their knowledge of the livestock industry as a whole.
Expected progeny differences (EPDs) allow for producers to estimate the genetic value of an animal as a parent. These are great things to use when determining what bull, boar, or ram you are going to purchase to own or use as an artificial insemination (A.I.) sire. One way to utilize EPDs is when determining which bull would be best for a first calf heifer. The bull with the highest calving ease direct number or the lowest birth weight would be the best to use for first calf heifers. This would be because there would be an increase chance of having unassisted births when calving time comes. However, there are other factors that impact calving ease including the body condition of the cow.
Producers and consumers of meat should be knowledgeable about how much meat can come from a beef steer or hog. The live weight is how much the animal weighs before processing. The carcass weight is the weight of the animal after it has been processed. Dressage percentage is the percentage of live weight that remains as carcass weight. The average dressing percentages are 61% for beef cattle, 59% for dairy steers, and 72% for hogs.
Each animal carcass can be divided into primal cuts (large sections). Primal cuts can then be broken down into smaller retail cuts that can be purchased at the store. By knowing where the primal cuts are on the animal, you can get an idea of how tough the meat can be (i.e. meat from the chuck or shoulder moves a lot, so it has more muscle groups with ligaments which are tougher to eat and thus are often cooked in the crock pot).
