Reducing GHG emissions through genetic improvement for feed efficiency: Effects on economically important traits and enteric methane production
Download2013
Baron, Vern S., Ominski, Kim H., Guan, Leluo, Basarab, John A., Beauchemin, Karen A., Miller, Stephen P.
Genetic selection for residual feed intake (RFI) is an indirect approach for reducing enteric methane (CH4) emissions in beef and dairy cattle. RFI is moderately heritable (0.26 to 0.43), moderately repeatable across diets (0.33 to 0.67) and independent of body size and production, and when...

Rumen microbial community composition varies with diet and host, but a core microbiome is found across a wide geographical range

Cox, Faith, Janssen, Peter H., Henderson, Gemma, Jonker, Arjan, Young, Wayne, Ganesh, Siva
Ruminant livestock are important sources of human food and global greenhouse gas emissions. Feed degradation and methane formation by ruminants rely on metabolic interactions between rumen microbes and affect ruminant productivity. Rumen and camelid foregut microbial community composition was...

Gene duplication is a widespread phenomenon in genome evolution, and it has been proposed to serve as an engine of evolutionary innovation. In the present study, we performed the first comprehensive analysis of duplicate genes in the bovine genome. A total of 3131 putative duplicated gene pairs...

The current recommended vitamin D intake guideline for diet and supplements during pregnancy is not adequate to achieve vitamin D sufficiency for most pregnant women
Download2016
Maggiore, Jack A., Eliasziw, Misha, Rabi, Doreen, O'Beirne, Maeve, Field, Catherine J., Hanley, David A., Dewey, Deborah, Aghajafari, Fariba, Weinberg, Amy, Kaplan, Bonnie J., Ross, Sue
Background The aims of this study were to determine if pregnant women consumed the recommended vitamin D through diet alone or through diet and supplements, and if they achieved the current reference range vitamin D status when their reported dietary intake met the current recommendations....

The effects of breed-type, sex and age on the density of four bovine limb bones were studied. The density of the four limb bones increased significantly with age, but the effects of breed-type and sex were variable. The results are discussed with reference to the densiometric method of predicting...

Data from carcasses of 210 cattle (119 bulls and 91 steers) from 4 breed types, serially slaughtered from = 200-008kg kg liveweight were used to test the hypothesis of similar gender dimorphism among breeds in relation to carcass bone growth and distribution. Relative to total bone weight, breed...

The cooking and eating quality characteristics of rib-eye roasts obtained from cows after removal from the breeding herd and after 8 or 16 wk of realimentation were determined. Evaluations of the effects of maturity class (physiological age) and external fatness on meat quality were also made....

The effects of dietary roughage level on the feedlot performance and carcass characteristics of bulls and steers
Download1978
Mathison, G. W., Price, M. A., Berg, R. T.
An experiment is described comparing bulls and implanted steers fed diets containing three roughage levels (20, 50 and 80% alfalfa–brome hay) with two pens of four cattle in each ’sex’ × dietary roughage level subgroup. Cattle were about 12 mo old and 230kg at the start of the trial. Each animal...

The effects of increasing dietary roughage level and slaughter weight on the feedlot performance and carcass characteristics of bulls and steers
Download1980
Price, M. A., Berg, R. T., Jones, S. D. M., Mathison, G. W.
A serial slaughter experiment is described comparing 45 bulls and 44 implanted steers. Nine of each 'sex' were slaughtered at the start of the trial and the remaining 71 were fed diets containing three roughage levels (20%, 50% and 80% alfalfa-brome hay) to two pen-average slaughter weights (450...

A trial is reported comparing muscle growth and distribution in l2 bulls and l2 heifers of each of two breed-types: Hereford (HE) and Dairy Synthetic (DY). Serial slaughter was carried out from weaning ( 163 + 15. I days) to approximately l5 mo of age.
