This is the only index that has no emphasis on fertility. The Herefords breed has a balance between the productive trait and carcass excellence, that is needed by the commercial beef industry together with other characteristics required, such as fertility, milking ability, hardiness, longevity, good feed conversion. Calves born in Nebraska weighed 92 pounds and had an assistance rate of 10 percent. 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. The more densely populated eastern area of the US, including herds in New England, was the early home of Herefords and from there they fanned out to the South and West as the population extended and the demand for beef increased. Breeding cattle with higher MARB EPDs should produce slaughter progeny with a higher degree of IMF and therefore higher quality grades. For example, the selection differential would be 60 pounds if heifers at weaning averaged 400 pounds BREED Birth Weight Weaning Weight Yearling Weight Angus 77.8 441 810 Polled Hereford 80.3 450 806 Hereford 81.4 442 800 Shorthorn 83.5 461 832 Brahman 87.8 447 744 Simmental 86.0 471 860 The average birth weight in babies of European & African descent is 3.5 kilograms .

Implanted pregnant heifers with zeranol were reported to have increased pelvic area in one trial but no increase in a second trial. Weaning weight was used as a predictor variable to increase the prediction accuracy of SC EPDs. Birth weight extremes ranged from a low of 45 lbs. This is equivalent to saying that the daughters are 10% more likely to remain in the herd to age 12. Consequently, it has been called the Konefal Method of daytime calving.

These summaries show exceptional bulls that sire progeny with breed-average or lower birth weights and well above average post-calving growth. The herd included 23 Hereford cows ranging in age from 2 to 12 years and 14 Simmental-Hereford half-blood cows aged 3 to 9 years. Research has also shown that the impact of birth weight on dystocia is greater in 2-year-old cows and that as cows become older birth weight assumes less significance.
