Oklahoma State Univ. The model for all traits except feed efficiency included fixed effects of sire breed, year within sire breed, crossbred dam group, age of dam, sex of calf and all two-way interactions.
Sires nested within year and sire breed was included as a random effect. Characterization of biological types of cattle-Cycle II. Sources of variation with a probability level of .2 or greater, including covariates, were omitted from the model, and least squares means were obtained from the reduced model. An evaluation of Limousin cattle. Firestorm . 0000007331 00000 n 0000005060 00000 n Sire breed effects on economic efficiency of a terminal-cross beef production system. Sign in. All rights reserved. The sire breed X crossbred cow group interaction for conformation score was significant (Table 2). See our current Gelbvieh, Angus & Red Angus sires. Carcass cutability, as calculated by the USDA equation, was similar for the sire breeds, but a sire breed X sex of calf interaction was found (Table 4). 0000004648 00000 n Characterization of biological types of cattle I. Dystocia and preweaning growth. Sci. All 3 breeds youve listed are continentals and should be suited for same environment. Sci., Virginia Polytechnic Inst. 0000011299 00000 n 0000003333 00000 n It's rare to get rat-tails from Gelbviehs, but it does happen. This makes for an excellent combination, as the Balancer cattle combines the Gelbvieh’s growth, muscle, leanness and fertility with the maternal nature and desirable marbling found in the Angus species. A well-designed crossbreeding system that captures the advantages of heterosis and utilizes these breed differences in a complimentary fashion is the most effective genetic resource for an efficient beef production system. Charolais sired calves were heavier at weaning than Limousin, Hereford, and Red Angus. Sci.
Calves born in 1982 and 1984 (409 head) were placed in a feedlot and fed ad libitum a corn-based finishing diet. 1985. Differences between the breed groups in slaughter weight are also reflected in carcass weight. Rankings within sire breed were the same, but Limousin-cross cattle tended to have a larger difference between steers and heifers. Although there was not a significant difference between sire breeds for calving difficulty score, an interaction (P < .05) between sire breed and age of dam was observed. vs. Hereford, P < 0.12) whereas on na-tive forages, Bons!nara-, Charolais-, and Gelbvieh-sired calves were similar but were heavier than Brangus- and Romosi-nuano-sired calves (P < 0.10). J. Anim. Calves were raised by their dams, without creep feed, on native and bermudagrass pastures until weaned at an average age of 205 d. Although calving difficulty was similar, Gelbvieh-sired calves were 1.0 kg heavier (P < .05) at birth and had 2.1% higher (P < .05) preweining mortality. She has over 20 years of experience working with cattle and crops. College of Agricultural Sciences & Natural Resources, College of Human & Environmental Sciences, Ag Education, Communications & Leadership, Master of International Agriculture Degree Program. Gelbvieh-sired cattle from Angus-cross cows were in the feedlot 11.4 d less than cattle from Hereford-cross cows, but Limousin-sired cattle from Angus-cross cows spent 3.5 d more in the feedlot than cattle from Hereford-cross cows. 229 talking about this. Karin Lindquist earned a BSc in Agriculture as an Animal Science major from the University of Alberta, Canada.
Currently, there are over 45,000 active, registered Gelbvieh cows in the United States. Gotti, J. E. 1982. 0000006287 00000 n 43:27. Gelbvieh-sired cattle were 13.1 kg heavier (P < .01) when placed in the feedlot and, because of similar daily gains, maintained an advantage (P < .05) at 365 d of age (448.8 vs 434.3 kg). A total of 778 calves from 28 bulls (seven per year) of each breed were produced from eight two-breed-cross cow groups.
