The NEW Interim Total Value balances 7 traits that have an impact on growth, carcase attributes and maternal factors.

The NEW Interim Total Value assists in making “balanced” selection decisions, taking into account the relevant calving ease (birth weight), growth, maternal and carcase attributes to identify animals that are most suitable for use within a particular commercial enterprise.

A new Total Value, reported in percentiles, includes emphasis on Birth Weight (2%), Weaning Weight (14%), Yearling Weight (12%), Mature Cow Weight (5%), Carcase Weight (30%), Milk (7%), MSA Marbling (30%).

Figure 1 shows the traits that are considered in the Total Value, and how much they contribute to the overall balance of the value. The larger the segment, the greater the impact. In the TBV, there is a focus on increasing growth resulting in heavier carcase weights and more MSA marbling, while maintaining calving ease and mature cow weight.

Figure 2 shows the selection advantage if heifers are selected using the NEW Interim Total Value. The selection advantage is calculated by ranking all animals currently tested via HeiferSELECT on Total Value, and comparing the average NEW Interim genomic predictions of the heifers in the top 10% with the average NEW Interim genomic predictions of all heifers available for selection.
