Infrared Thermography as an Indicator of Heat Loss in Fur-Chewing Chinchillas (Chinchilla Lanigera)
Contributor(s):: Łapiński, Stanisław, Orel, Joanna, Niedbała, Piotr, Kucharska, Weronika, Jakubowska, Magdalena, Lisowska-Lis, Agnieszka, Tombarkiewicz, Barbara, Lis, Marcin W.
Fur-chewing is a common problem in chinchilla (Chinchilla lanigera). It may affect the welfare of animals due to heat loss, thereby possibly impacting food and water intake to maintain body temperature. In this context, infrared thermography seems to be a suitable method of measuring heat...
Preferences for overhead sprinklers by naïve beef steers: Test of two nozzle types
Contributor(s):: Parola, Fabia, Hillmann, Edna, Schütz, Karin E., Tucker, Cassandra B.
Sprinklers effectively reduce heat load in cattle. In some studies, however, cattle readily use sprinklers, while others find that they either avoid or show no preference for it. These studies differ in many ways including previous experience of the animals and the amount of water delivered. Our...
Individual differences in metabolism predict coping styles in fish
Contributor(s):: Martins, Catarina I. M., Castanheira, Maria F., Engrola, Sofia, Costas, Benjamín, Conceição, Luís E. C.
Studies on metabolism usually rely on measurements of oxygen consumption obtained in respirometry chambers. Despite rigorous standardization there is still considerable inter-individual variation in metabolic rates which is often ignored. Furthermore, housing in respirometry chambers implies...
Sprinkler flow rate affects dairy cattle preferences, heat load, and insect deterrence behavior
Contributor(s):: Chen, Jennifer M., Schütz, Karin E., Tucker, Cassandra B.
Sprinklers provide benefits for cattle, such as reducing heat load and possibly deterring insects. However, the use of this resource by cows varies across studies. Some of this variation may, in part, be explained by sprinkler flow rate. Higher flow rates provide greater heat abatement (desirable...
Sprinkler flow rate affects dairy cattle avoidance of spray to the head, but not overall, in an aversion race
Spraying cattle with water elicits behavioral responses ranging from willing use to avoidance of wetting the head or entire body. This variation may be partly explained by sprinkler flow rate, as higher flow rates result in greater heat abatement and spray impact. An aversion race can be used to...
Oxygen consumption and swimming performance in Arctic charr with different pigmentation patterns
Contributor(s):: Magnhagen, Carin, Backström, Tobias, Nilsson, Jan, Brännäs, Eva
Pigmentation in animals often reflects behavioural and physiological traits, such as health status, stress responsiveness, and dominance. Individual variation in stress response and behaviour has earlier been proposed to be connected to differences in metabolism. The aim of this study was to...
Temperature-dependent consumption of drinking water in piglet rearing
Contributor(s):: Hoeck, J., Buscher, W.
This study focussed on examining the temperature-specific consumption of drinking water by piglets. To this end, a drinking trough system was developed to offer the animals water at three different temperatures (warm (+10°C then barn temperature), barn temperature (actual barn temperature) and...
The effects of simulated transport on the behaviour of eastern blue tongued lizards ( Tiliqua scincoides)
Contributor(s):: Mancera, K., Murray, P. J., Gao, Y. N., Lisle, A., Phillips, C. J. C.
There is widespread transport of reptiles for the pet trade throughout the world and the 'dead on arrival' rates are high. The eastern blue tongued (EBT) lizard ( Tiliqua scincoides; Order: Squamata; suborder: Lacertilia) is particularly popular due to its unusual blue tongue. Noise, vibration...
The human-animal interface of domestic livestock management and production and its relationship to brucellosis in the country of Georgia 2010: a rapid assessment analysis

Perceptions of animal physiotherapy amongst Irish veterinary surgeons
Contributor(s):: Aoife Doyle, Frances Horgan
The aim of this study was to investigate veterinary surgeons’ perceptions, knowledge and use of animal physiotherapy in the Republic of Ireland. A questionnaire was developed and sent to 200 veterinary surgeons, of which 97 were returned. Results indicated that 77 (79%) of respondents were aware...
Effect of a warm and flexible piglet nest heating system - the warm water bed - on piglet behaviour, live weight management and skin lesions
Contributor(s):: Ziron, M., Hoy, St
The aim of this investigation was to develop and test a new heating system for young piglets. Video observations were recorded, once a week over a 24-h period, with the help of an infrared video technique. The recordings were analysed to determine how long the piglets would remain in the nest...
Influence of straw length, sow behaviour and room temperature on the incidence of dangerous situations for piglets in a loose farrowing system
Contributor(s):: Burri, M., Wechsler, B., Gygax, L., Weber, R.
Crushing of piglets can be a major problem in loose-housing farrowing systems. In this study, we investigated the influence of straw of different lengths provided as nest-building material, sow behaviour and room temperature on the incidence of dangerous situations for the piglets. Piglets were...
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
Effect of broody hens on behaviour of chicks
| Contributor(s):: Shimmura, T., Kamimura, E., Azuma, T., Kansaku, N., Uetake, K., Tanaka, T.
The objective of the present study was to examine the details of dynamic changes of behaviour of brooded and non-brooded chicks at an early age, the effects of broody hens on the behavioural development and fearfulness of chicks and the correlation between maternal care and fearfulness of chicks,...
The influence of social factors on the use of shade by sheep
| Contributor(s):: Sherwin, C. M., Johnson, K. G.
In a study of 39 Merino wethers on pasture with natural shade, over 9 days in which maximum temperatures varied between 29 degrees and 39.5 degrees C, sheep that moved to the shade first stayed there the longest. Sheep that butted most and were high in the butting hierarchy remained in shade for...
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...
