Farmer and Public Attitudes Toward Lamb Finishing Systems
Contributor(s):: Coleman, Grahame, Jongman, Ellen, Greenfield, L., Hemsworth, Paul
To develop research and policy on the welfare of lambs in intensive finishing systems, it is important to understand public and sheep farmers' attitudes. The aim of this research was to identify and compare farmer and community attitudes relevant to the intensification of lamb finishing. The...

Effects of growth-promoting technology on feedlot cattle behavior in the 21 days before slaughter
Contributor(s):: Stackhouse-Lawson, K. R., Tucker, C. B., Calvo-Lorenzo, M. S., Mitloehner, F. M.
There is growing interest in the animal welfare implications of growth-promoting technology used in feedlot cattle, namely hormonal implants, ionophores, antibiotics and β 2-adrenergic agonists. Previous studies have focused on the effects of implants on aggression, but little work has...
Spectral analysis of feeding and lying behavior of cattle kept under different feedlot conditions
Contributor(s):: Wilson, S. C., Dobos, R. C., Fell, L. R.
This study used spectral analysis in 2 separate experiments to examine feeding and lying behavior of Bos taurus steers under 2 housing treatments: a feedlot yard stocked at 12.0 m2 per head with a dry, firm pen surface (NDF) and a "high density" (HDF) feedlot yard stocked at 6.0 m2 per head with...

An assessment of several potential enrichment devices for feedlot cattle
Contributor(s):: Wilson, S. C., Mitlohner, F. M., Morrow-Tesch, J., Dailey, J. W., McGlone, J. J.
The behaviour of Charolais cross heifers kept in experimental feedlot pens (3 pens, N=10 per pen) was observed for frequency and duration of use of and percentages of animals interacting with five environmental potential enrichment devices (PEDs) over a period of 22 days. The PEDs tested were:...
Quality of handling and holding yard environment, and beef cattle temperament: 2. Consequences for stress and productivity
Contributor(s):: Petherick, J. C., Doogan, V. J., Venus, B. K., Holroyd, R. G., Olsson, P.
This experiment assessed the effects of different quality and quantity of handling and quality of the holding yard environment on the productivity and physiological parameters indicative of stress in beef cattle. One-hundred-and-forty-four steers were given one of three human handling and yarding...
Effect of housing on in situ postures of gestating gilts
Contributor(s):: Taylor, L., Friend, T., Smith, L. A.
Behaviour of gilts housed in tethered housing, crates, loose housing or dirtlot was video-recorded for 48-h observation periods commencing on days 0, 7 and 63. Lying was the most frequent activity, ranging from 65 to 90
The response of Merino wethers to feedlotting and subsequent sea transport
Contributor(s):: Bailey, A. N., Fortune, J. A.
During an 8-day assembly phase in a feedlot, sheep (n = 1500) given a shipping pellet (SP) consisting mainly of cereal straw and barley grain gained about 1 kg liveweight, while those on a lupin pellet (LP) of lupin hulls and kernels lost 1 kg. Farm source of sheep had a significant effect on...
An examination of some physiological variables for assessing the welfare of beef cattle in feedlots
Contributor(s):: Wilson, S. C., Fell, L. R., Colditz, I. G., Collins, D. P.
Some physiological variables which could aid in assessing the welfare of beef cattle in feedlots were screened in this exploratory study. In two experiments, each of 42 days duration, the physiological responses of Bos taurus steers to three treatments were investigated: pasture (rotation between...
Strengthening US organic standards on animal health and welfare
Contributor(s):: Merrigan, K. A., Bailey, M. R., Lockeretz, W.
Organic livestock production has been increasing in the US, although it still merely constitutes a small fraction of total production. Its success will require detailed standards supported by scientific knowledge and consistent with organic farming principles. However, such standards, mandated...
