MARGINAL ECONOMIC VALUES INDUSTRY PROFIT INDEX:
Mature Weight: Body weight of cows adjusted to six years of age at body condition score 5. MWT is reported in pounds and is computed from a genetic model that leverages information from weaning weight, post-weaning gain, and mature weights of cows. Reported weights are adjusted for both age at observation and for body condition. Body weights of cows 2 to 12 years of age are utilized in the evaluation so producers can report data at any age for the evaluation. Preferably, cows should be evaluated at or shortly following weaning, as that’s a convenient time for many producers to process cows. Weight collected at other times in the production cycle are acceptable. Producers should measure full contemporary groups on the same day as the observation date, which helps form the contemporary group. Cow Energy Requirement-Yearly (CERY): Mature body weight, lactation potential, and birth weight are primary predictors of energy requirements. Mature Weight, Milk, and Birth Weight EPD are utilized to inform prediction equations from beef cow nutrition research to estimate differences in energy requirement over a production year. The CERY EPD is reported in pounds of Total Digestible Nutrients (TDN) required for an age 6 cow.
