Yield and Quality of Holstein Beef
نویسنده
چکیده
Beef derived from Holstein steers is a significant source of the U.S. beef supply. The nation’s 9.1 million dairy cows in 2003 were 22% of the U.S. cow herd (NASS, 2005). Given the typical breed distribution of dairy cows, calving interval, full-term pregnancy rate, peri-natal calf death loss (NAHMS, 2002), gender distribution, dairy beef placement (80%) and survival to market (94%), it can be estimated that 2.35 million Holstein steers are marketed annually. This population constitutes about 8.0-8.5% of the 28 million head (Cattle-Fax, 2005) of U.S. finished steer and heifer harvest. This estimate exceeds the frequency (5.7%) of Holsteins observed in the 2000 National Beef Quality Audit (McKenna et al., 2002). Given the distinctive Holstein coat color pattern and lack of crossbreeding in the dairy industry, Holstein genetics may be the largest recognizable single-breed source of beef in the U.S. Dairy cattle breeders have selected for milk production and milk components, and not meat yield or quality traits, so the resulting finished Holstein steer population has the potential to be relatively homogeneous in meat yield and quality if management and other environmental sources of variation are minimized. The purpose of this review is to highlight research of the past 25 years that describes Holstein steer meat yield and quality. Beef derived from Holstein cows culled from the dairy herd is also a significant source of beef in the U.S., but this source will not be addressed here.

Effect of Forage Feeding Level on Performance, Meat Quality and Economic Costof Holstein Beef Calves Fed Organic Diet
The aim of this study was to compare conventional and organic diets in beef production. Thirty-two dairy beef calves were used in 4 treatments: organic diet with three levels of forage [70% of organic diet with high amount of forage (ORH), 55% of organic diet with medium amount of forage (ORM), 38% of organic diet with low amount of forage(ORL)] and conventional diet (CON). The dry matter intak...

Analyses were conducted to evaluate the ability of the USDA yield grade equation to detect differences in subprimal yield of beef-type steers and calf-fed Holstein steers that had been fed zilpaterol hydrochloride (ZH; Intervet Inc., Millsboro, DE) as well as those that had not been fed ZH. Beef-type steer (n = 801) and calf-fed Holstein steer (n = 235) carcasses were fabricated into subprimal ...

Effects of dietary vitamin E supplementation on drip loss, cooking loss, and muscle fiber disruption in fresh beef loin steaks from Holstein and crossbred beef steers were studied. Nine Holstein steers and nine beef steers were fed a control diet and nine Holstein steers and eight beef steers were supplemented daily with 298 IU of vitamin E/kg of diet for 211, 232, or 252 d. Drip loss, cooking ...
متن کاملEffects of zilpaterol hydrochloride on retail yields of subprimals from beef and calf-fed Holstein steers.
Retail cutting tests were conducted on subprimals from cattle fed zilpaterol hydrochloride (ZH) to determine if the improved carcass composition and red meat yield resulting from ZH feeding would translate into increased retail yields of ready-to-cook products. As part of a 3-phase study, selection of carcasses from Holstein steers was done once (fall 2008), followed by the collection of carcas...
