[QUOTE="Lazy M, post: 1488375, member: 19946"] Sort of related, I found an article from University of Missouri that showed the bw and calving difficulty associated with different breed sires on a herd of similar Angus/Hereford cattle. They considered "calving difficulty" if they had to provide assistance. I believe that they used sires that were at breed average for CE and/or BW. Table 3 Breed of sire effects on calving difficulty and birth weight Breed of sire Calving difficulty Birth weight Hereford and Angus 2.9 percent 78.7 pounds Jersey 2.9 percent 68.6 pounds Red Poll 3.7 percent 78.7 pounds Tarentaise 6.0 percent 82.7 pounds Sahiwal 6.2 percent 83.8 pounds Pinzgauer 6.3 percent 86.4 pounds Gelbvieh 8.0 percent 86.0 pounds Brown Swiss 8.4 percent 85.6 pounds Limousin 9.4 percent 85.8 pounds Brahman 10.0 percent 90.2 pounds Chianina 11.0 percent 89.3 pounds South Devon 11.9 percent 83.1 pounds Simmental 14.9 percent 88.9 pounds Charolais 18.4 percent 90.6 pounds Maine Anjou 20.4 percent 90.6 pounds Overall average 8.3 percent 83.5 pounds Note Calves were out of Hereford and Angus cows, 4 years old and older.
