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...
