MARVEL continues to bring in the purple banners with show winners across the country. He consistently sires extra eye appeal. His offspring are sound structured and free moving with a powerful hip, deep body and overall stoutness.

studies, in which Angus cattle demonstrate a superior ability to marble, Herring highlights several studies. Those included comparisons of high- and low-marbling-EPD registered Angus bulls bred to composite cows at the Roman L. Hruska U.S. Meat Animal Research Center (USMARC). The top bull EPDs were +0.33 and the low bulls were -0.35 in the 1995

In this study, facilitated by multiple universities, researchers aimed to learn more about marbling, or intramuscular fat, in order to improve it without compromising subcutaneous fat, or backfat.

Among those were comparisons of high- and low-marbling-EPD registered Angus bulls bred to composite cows at the USDA Meat Animal Research Center. The top bull EPDs were +.33 and the low bulls were -.35 in the 1995 Angus Sire Summary, but fat thickness EPD was similar for all.

Aug 4, 2022 · Based on Angus Breedplan, the main factors of marbling in beef cattle include a group of important actions that must be integrated into the farmer's management plan. Genetics Marbling is moderately heritable (30-50%) and can be improved through genetic selection.

The value for marbling in the Angus breed is 0.45, which means genetics account for 45% of the variation in phenotype. However, that implies 55% is due to something else, primarily environment and management.

Reverter et al. (2000) found higher genetic correlations between yearling heifer ultrasound IMF and carcass IMF in Australian Angus and Hereford cattle, as compared to yearling bull ultrasound IMF.

The following two bulls have new carcass EPD profiles. Assume that both sires have similar accuracies and are mated to comparable females. Calves are fed out, managed and harvested under the same conditions: On average, we would expect the carcasses from Sire A’s calves to have 0.33 higher marbling score than the carcasses from Sire B’s ...

Jun 15, 2004 · But for some strange reason, I think that Angus bulls should marble, at least breed average. Click to expand... Approximately half of all Angus bulls are below breed average for IMF EPD.

Currently the average marbling EPD in the Angus breed is + 0.41 and has a range from -0.77 to +2.15. Today we have cattle with superior genetic ability to deposit marbling but we may need to rethink our traditional approach to finishing beef systems.
