To determine consumer sensory acceptance and value of beef steaks differing in marbling level (high = upper USDA Choice and low = USDA Select), but similar in Warner-Bratzler shear value, consumers in Chicago and San Francisco (n = 124 per city) evaluated two matched pairs of high- and low-marbled strip steaks, and had the opportunity to participate in a silent, sealed-bid auction to purchase s...

Pigs from the F(2) generation of a Duroc x Pietrain resource population were evaluated to discover QTL affecting carcass composition and meat quality traits. Carcass composition phenotypes included primal cut weights, skeletal characteristics, backfat thickness, and LM area. Meat quality data included LM pH, temperature, objective and subjective color information, marbling and firmness scores, ...

The ham from Iberian pigs is a meat product of high sensorial quality, with a first-rate consumer acceptance. Its excellent sensorial characteristics are basically due to the extensive feeding system of Iberian pigs, based on acorns and grass, and the prolonged technological processing of the ham (18-24 months). Iberian hams present high intramuscular fat content and marbling. Currently, chemic...

Carcass data from 6,795 Simmental-sired animals born from 1992 to 2001 were used to determine whether adjustment to a constant age, back-fat, HCW, or marbling score would result in differences in heritability of the carcass traits and, correspondingly, if EPD calculated using those variance components and adjustments would result in sire reranking. The endpoints were age (EPA), backfat (EPF), H...

Recent research has shown a negative correlation between marbling and serum retinol concentration in Japanese Black cattle. Three hundred sixty single-source black, yearling steers (average initial BW = 316 ± 9.1 kg) fed a 91 % concentrate (steam-flaked corn base) diet were used to evaluate the effects of supplemental vitamin A concentration on performance, DMI, and carcass traits. Steers were ...

Anabolic implants are routinely used in the finishing phase of beef production to improve animal performance and feed efficiency. Implanting during the feedlot phase on average increases ADG 18%, feed intake 6%, feed efficiency 8%, carcass weight 5% and ribeye area 4% compared with non-implanted controls. Implants reduce the cost of beef production, which is important given current high feed co...

Abstract The objective of this study was to evaluate the effect days on feed (DOF) performance, health, carcass, and organ characteristics composite Angus x Holstein heifers (n = 3,676). At time arrival (d 0), from a single source were placed into large (~300 animal) pens at two commercial feedlot locations in Texas Panhandle. administration final implant (Revalor® 200; d 240), heifers, within ...
