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,...

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...
