Physiological and behavioural alterations in disbudded goat kids with and without local anaesthesia
Contributor(s):: Alvarez, L., Nava, R. A., Ramirez, A., Ramirez, E., Gutierrez, J.
The physiological and behavioural responses were evaluated in goat kids that were disbudded either with or without local anaesthesia, in a study with 56 animals randomly allocated among five groups. The anaesthesia/disbudding group (AD, n=12) was treated with 2 mL 2% lidocaine (L2
The use of a heated floor area by sows and piglets in farrowing pens
Contributor(s):: Pedersen, L. J., Malmkvist, J., Jorgensen, E.
Twenty-six sows housed in farrowing pens were observed from 5 days prior to until 5 days after parturition. Pens consisted of a resting area with solid concrete floor and an activity area with drained concrete floor. The sows were randomly distributed between two pen types: Pens where the floor...
The use of water-cooled roosts by hens for thermoregulation
Contributor(s):: Muiruri, H. K., Harrison, P. C., Gonyou, H. W.
Experiments were conducted to determine whether hens would use water-cooled roosts for thermoregulation during exposure to high ambient temperatures. In the first experiment 8 groups of broiler breeder hens were tested in 25 +or- 1 and 35 +or- 1 degrees C ambient environments. Each group had...
Acid-base responses of fat-adapted horses: relevance to hard work in the heat
Contributor(s):: Kronfeld, D. S., Custalow, S. E., Ferrante, P. L., Taylor, L. E., Wilson, J. A., Tiegs, W.
Feeding and training may affect acid-base responses to strenuous exercise. Acidosis usually correlates with higher blood lactate concentrations during intense exercise, but alkalosis has been found in horses, and higher lactate responses during sprints have been found in fat adapted horses. A...
Thermal behaviour of growing pigs in response to high temperature and humidity
Contributor(s):: Huynh, T. T. T., Aarnink, A. J. A., Gerrits, W. J. J., Heetkamp, M. J. H., Canh, T. T., Spoolder, H. A. M., Kemp, B., Verstegen, M. W. A.
The effects of high ambient temperatures and humidities on thermal behavioural adaptation and pen fouling of group-housed growing pigs were assessed. Twelve groups of 10 gilts of an average initial body weight (BW) of 61.7 kg were used. During nine experimental days, ambient temperatures were...
Animal welfare and economic optimisation of farrowing systems. (Special Issue: Knowing animals.)
Contributor(s):: Ahmadi, B. V., Stott, A. W., Baxter, E. M., Lawrence, A. B., Edwards, S. A.
In many countries, including the UK, the majority of domestic sows are housed in farrowing crates during the farrowing and lactation periods. Such systems raise welfare problems due to the close confinement of the sow. Despite the fact that many alternative housing systems have been developed, no...
Behaviour and thermogenesis of racing pigeons housed under transport conditions
Contributor(s):: Gorssen, J., Koene, P.
Behaviour and thermogenesis of homing pigeons (Columba livia) in crowded transport conditions were studied in 2 experiments. Both experiments were designed on a 2-way factorial basis and measurements and observations were taken from groups of 8 birds. In the first experiment, temperature (26...
