However, the Jersey, Brahman, and Sahiwal (a Zebu breed) F1 cows experienced a somewhat lower incidence of dystocia than the other crosses. Each calf had a coronet band circumference measured using the Calfscale tape, and had also been weighed at birth using scales. Selecting the older heifers in a calf crop should likewise lead to less dystocia because they will be larger when their first calves are born. YW EPD is an estimate of post-weaning growth that is measured in pounds. adElem.style.zIndex = ''; Breeding cattle with higher MARB EPDs should produce slaughter progeny with a higher degree of IMF and therefore higher quality grades. .

Both sires may have calves weighing the same amount, as illustrated by the area where the two curves overlap, but on the average the difference is 5 lb. The genetic correlations between actual birth weight (scale) and predicted birth weight (coronet band tape) for male Hereford calves, female Hereford calves, and both sexes combined. adElemSticky.style.height = rect.height + 'px';
Sires with relatively higher REA EPDs are expected to produce better-muscled and higher percentage yielding slaughter progeny than will sires with lower REA EPDs. adElem.style.height = ''; There is a slightly positive weight on Weaning Weight, Mature Cow Weight and Milk which accounts for enough growth but ensures females do not increase inputs. Birth Weight. Increasing the level of dietary energy resulted in increased birth weights but not increased dystocia; in fact, the incidence of calving difficulty was lower in the medium- and high-energy groups than in the low-energy group.
