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...

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.

Berg, R. T., Price, M. A., Jones, S. D. M.
Two breeds (Hereford (HE), and Dairy Synthetic (DY)), and two sexes (bulls and heifers) were compared for various measures of efficiency in beef production. DY animals had greater (P < 0.001) birthweights, and greater weaning weights (P < 0.001) than HE animals. At weaning, 16 animals of each...

Harding, John C.S., Foxcroft, George R., Gunvaldsen, Rayna E., Dyck, Michael K., Plastow, Graham S., Detmer, Susan E., Wilkinson, Jamie M., Dixon, Walter T.
Influenza viruses are a common cause of respiratory disease in swine. Infections range in severity from asymptomatic to causing significant morbidity. The main objective of this study was to compare lung transcriptomic and epigenetic responses to influenza infection in pigs from high or low birth...

Plastow, G., Lunney, J. K., Ladinig, A., Ashley, C., Detmer, S. E., Wilkinson, A., Harding, J. C. S.
In spite of extensive research, the mechanisms of reproductive disease associated with Porcine Reproductive and Respiratory Syndrome virus (PRRSv) are still poorly understood. The objectives of this large scale study were to evaluate associations between viral load and fetal preservation,...
