Genetic parameters for production and feeding behaviour traits in crossbred steers fed a finishing diet at different ages
Download2013
Wang, Z., Nkrumah, D. J., Basarab, J. A., Durunna, O. N., Okine, E. K., Moore, S. S., Mujibi, F. D. N.
Because cattle can be raised postweaning under several feeding regimes, this study examined the consistency of phenotypic and genetic parameters of some production and feeding behaviour traits between two feeding periods that beef cattle received a finisher diet. Crossbred steers (n=851) were...

Greenhouse gas emissions from calf- and yearling-fed beef production systems, with and without the use of growth promotants
Download2012
Baron, V. S, Aalhus, J. L., Basarab, J. A., López-Campos, Ó., Haugen-Kozyra, K., Okine, E. K.
A spring calving herd consisting of about 350 beef cows, 14–16 breeding bulls, 60 replacement heifers and 112 steers were used to compare the whole-farm GHG emissions among calf-fed vs. yearling-fed production systems with and without growth implants. Carbon footprint ranged from 11.63 to 13.22...

Influence of sire breed on the interplay among rumen microbial populations inhabiting the rumen liquid of the progeny in beef cattle
Download2013
Guan, L. L., Wang, Z., Zhou, M., Goonewardene, L. A., Moore, S. S., Hernandez-Sanabria, E.
This study aimed to evaluate whether the host genetic background impact the ruminal microbial communities of the progeny of sires from three different breeds under different diets. Eighty five bacterial and twenty eight methanogen phylotypes from 49 individuals of diverging sire breed (Angus,...

Interactive effects of low voltage electrical stimulation and leg restraint on meat quality of Charolais crossbred steer carcasses
Download1990
Jones, C. R., Bruce, H. L., Ball, R. O.
The meat quality of the longissimus muscle of 12 Charolais crossbred steers that were electrically stimulated on randomly selected sides approximately 1 h postmortem was investigated. Temperature and pH measurements were taken on each side at 5 min prior and 1, 4, 24 and 48 h subsequent to...

Modification of beef quality through steer age at slaughter, breed cross and growth promotants
Download2012
Aalhus, J. L., Basarab, J. A., Girard, I., Bruce., H. L., Larsen, I. L.
A 23 factorial experiment tested the interactions of slaughter age (12–13 or 18–20 mo), growth implants use (Component E-S, TE-S), ractopamine hydrochloride (RAC) feed supplementation use and breed cross [Hereford–Aberdeen Angus (HAA) or Charolais–Red Angus (CRA)] on pH, temperature, objective...

Bruce., H. L., Aalhus, J. L., Larsen, I. L., Girard, I., Basarab, J. A.
A 24 factorial experiment tested the interactions of slaughter age (12–13 or 18–20 mo), growth hormone use, β-adrenergic agonist (β-AA) use and breed cross [Hereford–Aberdeen Angus (HAA) or Charolais–Red Angus (CRA)] on the composition, fibre types, and connective tissue characteristics of m....

Patterns of muscle, bone and fat accretion in three biological types of feedlot bulls on three dietary energy levels
Download1985
Patterson, D. L., Price, M. A., Berg, R. T.
The data used in this study consisted of 119 075 complete lactation records accumulated by record of performance (ROP) from 1976 to 1981. Each individual record consisted of 7, 8 or 9 monthly test day milk weights and corresponding fat percentage. The data for each breed (Ayrshire, Guernsey,...

Phenotypic correlations of fatty acid composition among intramuscular, subcutaneous and intermuscular fat tissues in concentrate-fed beef cattle of differing genotypes
Download2009
Wang, Z., Aldai, N., Osoro, K., Dugan, M. E. R., Crews Jr, D. H., Li, C.
In an attempt to predict intramuscular fatty acid composition using easily accessible fat depots, between-tissue correlations were studied in 75 Asturiana de los Valles bulls with different levels of muscular hypertrophy, and 25 Asturiana de la Montaña bulls. Trans-18:1 in intramuscular fat was...

Subcutaneous fatty acid composition of steers finished as weanlings or yearlings with and without growth promotants
Download2013
Baron, V. S., Aalhus, J. L., Turner, T. D., Dugan, M. E. R., Mapiye, C., Basarab, J. A.
Background The current study evaluated the subcutaneous fatty acid (FA) composition of calf- and yearling-fed steers with or without growth promoting implants. Crossbred steers (n = 112; 267 ± 5.0 kg) of the same contemporary group were allocated to one of four production system and implant...
