Contributor(s):: Dana L. M. Campbell, Jim M. Lea, William J. Farrer, Sally J. Haynes, Caroline Lee
Global Positioning System (GPS)-based virtual fences offer the potential to improve the management of grazing animals. Prototype collar devices utilising patented virtual fencing algorithms were placed on six Angus heifers in a 6.15 hectare paddock. After a “no fence” period,...

Changes in behaviour of dairy cows with clinical mastitis
Contributor(s):: Sepulveda-Varas, P., Proudfoot, K. L., Weary, D. M., Keyserlingk, M. A. G. von
Behaviour is an important tool for recognizing illness in animals. One of the most common diseases in dairy cattle is clinical mastitis. Evidence suggests that cows with this disease show sickness behaviours, but little is known about the progression of behavioural changes before and after the...
Density-dependent diet selection and body condition of cattle and horses in heterogeneous landscapes
Contributor(s):: Cornelissen, P., Vulink, J. T.
For some decades, grazing by cattle and horses is used as a management tool to achieve different nature management goals. For managers there are still questions to be answered about the effects of herbivore densities on their performance, vegetation development and biodiversity. This study...
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...
What do calves choose to eat and how do preferences affect behaviour?
Contributor(s):: Webb, L. E., Engel, B., Berends, H., Reenen, C. G. van, Gerrits, W. J. J., Boer, I. J. M. de, Bokkers, E. A. M.
Calves raised for milk or meat are fed diets that differ from feral-herd calf diets and are based on the nutritional requirements of the 'average calf'. These diets may not meet the dietary preferences of each individual calf. This study explored diet preferences in calves with free dietary...
Young Blond d'Aquitaine, Angus and Limousin bulls differ in emotional reactivity: relationships with animal traits, stress reactions at slaughter and post-mortem muscle metabolism
Contributor(s):: Bourguet, C., Deiss, V., Boissy, A., Terlouw, E. M. C.
The present study investigated relationships between reactivity during tests, stress reactions at slaughter and animal traits in young Blond d'Aquitaine (BA), Limousin (LI) and Angus (AN) bulls. Behavioural and physiological reactivity of animals was evaluated during rearing using a "Human test"...
Are "pit bulls" different? An analysis of the pit bull terrier controversy (Commenrtary)
Contributor(s):: Lockwood, R., Rindy, K.
"This article reviews some of the historical, ethological, and epidemiological evidence relevant to the question of whether pit bull terriers present special animal control problems justifying unusual legislative action."
A note on the effect of controlling stable flies ( Stomxys calcitrans ) in the resting activity and pen distribution of dairy cows
Contributor(s):: Vitela, I., Cruz-Vazquez, C., Orihuela, A.
This study investigated the effect of controlling stable flies (Stomoxys calcitrans) on the number of dairy cows lying down and their pen distribution. The study randomly assigned 80 Holstein cows to 1 of 2 groups. The treated group (T) included cows individually sprayed with insecticide when...
Assessing the welfare of dairy cattle. (Special issue: food animal husbandry and the new millennium)
Contributor(s):: Rushen, J.
This article suggests that health problems represent some of the main threats to the welfare of dairy cattle. Although disagreement often arises about what constitutes the main welfare problems, there is broad agreement that welfare is reduced by health problems. In recent decades, a marked...
Dairy cow behavior and welfare implications of time waiting before entry into the milking parlor
Contributor(s):: Dijkstra, C., Veermae, I., Praks, J., Poikalainen, V., Arney, D. R.
The objective of this study was to investigate dairy cows' time spent in the possibly stressful waiting area (WA) of the milking parlor (MP) and their behavioral patterns while there and thereby investigate comparative effects on their welfare. The experiments were carried out in 3 loose-housing...
Handling, electric goad, and head restraint: effects on calves' behavior
Contributor(s):: Goonewardene, L. A., Price, M. A., Stookey, J. M., Day, P. A., Minchau, G.
96 weaned calves (48 bulls and 48 heifers) were allocated in a 2 x 2 x 2 arrangement to 3 treatments each with 2 levels: calves handled every 10 days or 20 days; an electric goad used or not used; and head gate restrained or not restrained. Behaviour responses were measured by 5 incremental...
Oral behaviors of beef steers in pen and pasture environments
Contributor(s):: Ishiwata, T., Uetake, K., Kilgour, R. J., Eguchi, Y., Tanaka, T.
This study observed the behavioral characteristics of 122 steers in eight pens and 1,136 steers at six pastures. Nonhuman animals kept in pens performed less nutritive oral behaviors and more nonnutritive oral behaviors than animals kept at pasture. Although these could not be described as...
Scientists' assessment of the impact of housing and management on animal welfare
A total of 22 scientists contributed to a consensus-oriented conceptual framework for assessment of farm animal welfare, addressing priority issues in cattle, pigs, and chickens. They used the Delphi method, in which participants contributed anonymously through e-mail. The framework puts welfare...
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...
The effects of lameness on social and individual behavior of dairy cows
Contributor(s):: Galindo, F., Broom, D. M.
Lameness is one of the most important welfare problems in dairy cattle. Most studies on lameness have focused on wide ranging surveys to identify causal factors, but few have considered the welfare implications of this disorder. In this study, we compared the social and individual behaviour of 10...
A comparison of welfare outcomes for weaner and mature Bos indicus bulls surgically or tension band castrated with or without analgesia: 2. Responses related to stress, health and productivity
Contributor(s):: Petherick, J. C., Small, A. H., Mayer, D. G., Colditz, I. G., Ferguson, D. M., Stafford, K. J.
Tension banding castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the banders as a humane castration method. Two experiments were conducted, under tropical conditions using Bos indicus bulls comparing tension banding (Band) and...
Administration of a NSAID (meloxicam) affects lying behaviour after caesarean section in beef cows
Contributor(s):: Barrier, A. C., Coombs, T. M., Dwyer, C. M., Haskell, M. J., Goby, L.
Very little is known about the pain experienced by cattle following caesarean section and hence little consideration has been given to managing it. Thus the purpose of this study was to investigate activity-related behavioural changes in response to pain, by pre-emptively administering a long...
