Environmental and Physiological Factors Associated With Stamina in Dogs Exercising in High Ambient Temperatures
Contributor(s):: Patrick J. Robbins, Meghan T. Ramos, Brian M. Zanghi, Cynthia M. Otto
This IACUC approved study was performed to evaluate the environmental, physiological, and hematological components that contribute to stamina following successive bouts of exercise that included searching (5-min), agility (5-min), and ball retrieve (<10-min). Regularly exercised dogs (N= 12)...
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...
Do collar-mounted predation deterrents restrict wandering in pet domestic cats?
Contributor(s):: Hall, C. M., Bryant, K. A., Fontaine, J. B., Calver, M. C.
Roaming pet cats kill and harass wildlife, hybridise with wild felids, interbreed with feral populations, spread disease or annoy neighbours, and endanger their own welfare by fighting, being struck by vehicles or ingesting poisons. Confinement of pet cats is unpopular, so alternative methods to...
Impacts of shade on physiological and behavioural pattern of Dehong buffalo calves under high temperature
Contributor(s):: Gu, ZhaoBing, Yang, ShuLi, Leng, Jing, Xu, ShaoHong, Tang, ShouKun, Liu, ChuanBin, Gao, YaJun, Mao, HuaMing
Shade shelter is widely used to reduce heat load for farm animals, but little research focus on the cooling effects for Dehong buffalo calves. The aim of this experiment was to evaluate the impacts of shade cooling on the physiological and behavioural parameters for Dehong buffalo calves. Shade...

Genetic study of stress assessed with infrared thermography during dressage competitions in the Pura Raza Espanol horse
Contributor(s):: Sanchez, M. J., Bartolome, E., Valera, M.
Despite the fact that physiological parameters in dressage are important because of their close connection to human-horse accidents, performance and welfare, these parameters are only rarely included in horse breeding programs. In Spain, the Pura Raza Espanol horse (PRE) Breeding Program focuses...
Behavioural responses of broiler chickens during low atmospheric pressure stunning
Contributor(s):: Mackie, N., McKeegan, D. E. F.
Low atmospheric pressure stunning (LAPS) is a new irreversible stunning method for broiler chickens ( Gallus gallus domesticus), which has the potential to improve welfare during routine slaughter. During LAPS, birds are placed in a hypobaric chamber that allows oxygen to be gradually removed...
Stocking density affects welfare indicators of growing pigs of different group sizes after regrouping
Contributor(s):: Fu, LingLing, Li, HuiZhi, Liang, TingTing, Zhou, Bo, Chu, QingPo, Schinckel, A. P., Yang, XiaoJing, Zhao, RuQian, Li, PingHua, Huang, RuiHua
In recent years, the concept of animal welfare began to be accepted by the Chinese people. On some intensive pig farms, the stocking density for growing pigs is too great, leading to decreased animal welfare. In order to study the relationships between stocking density and welfare indicators and...
On-farm evaluation of the Salmon Welfare Index Model (SWIM 1.0): theoretical and practical considerations
Contributor(s):: Folkedal, O., Pettersen, J. M., Bracke, M., Stien, L. H., Nilsson, J., Martins, C., Breck, O., Midtlyng, P. J., Kristiansen, T.
The present study investigated the operational feasibility of the recently developed Salmon Welfare Index Model (SWIM 1.0) designed for Atlantic salmon ( Salmo salar L) in production cages. Ten salmon farms containing spring smolts were visited twice, first between May and June the first year in...
Effects of maternal vocalisations on the domestic chick stress response
Contributor(s):: Edgar, J., Kelland, I., Held, S., Paul, E., Nicol, C.
Although natural brooding is not commercially feasible, there is great potential to simulate aspects of maternal care to improve the welfare of farmed domestic chicks. Our previous studies showed that the presence of calm broody hens can buffer mild stress responses in chicks, although the...
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...
Achieving optimum performance in a loose-housed farrowing system for sows: the effects of space and temperature
Contributor(s):: Baxter, E. M., Adeleye, O. O., Jack, M. C., Farish, M., Ison, S. H., Edwards, S. A.
Piglet survival relies on interactive influences of the sow, her piglets and their environment. There are a number of design challenges in a loose-housed farrowing and lactation system to optimise this dynamic, including achieving farrowing in the desired location (i.e. a protected nest area) and...
Factors affecting penetrating captive bolt gun performance
Contributor(s):: Gibson, T. J., Mason, C. W., Spence, J. Y., Barker, H., Gregory, N. G.
Captive bolt stunning is used for rendering livestock insensible at slaughter. The mechanical factors relating to performance of 6 penetrating captive bolt gun (CBG) models were examined. The Matador Super Securit 3000 and the .25 Cash Euro Stunner had the highest kinetic energy values (443 J and...
Early transfer of mated females into the maternity unit reduces stress and increases maternal care in farm mink
Contributor(s):: Malmkvist, J., Palme, R.
Mated mammals on farms are typically transferred to another housing environment prior to delivery. We investigated whether the timing of this transfer - EARLY (Day -36), INTERMEDIATE (Day -18), or LATE (Day -3) relative to the expected day of birth (Day 0) - affects maternal stress, maternal care...
Drinking behaviour in sows kept outdoors during the winter months
Contributor(s):: Andersen, H. M. L., Pedersen, L. J.
In the light of the EU regulation, "pigs must have permanent access to a sufficient quantity of fresh water" and the practical problems it provides farmers during winter to keep water free of ice, the aim of this study was to investigate the influence of periods with frost on the diurnal pattern...
Environmental complexity and use of space in slow growing free range chickens
Contributor(s):: Rodriguez-Aurrekoetxea, A., Leone, E. H., Estevez, I.
Production environments for meat poultry are generally bi-dimensional open areas where birds tend to cluster along the walls. We investigated the impact of increasing environmental complexity (EC) on slow-growing free-range chickens raised under commercial conditions. The study was conducted in...
Killing of spent laying hens using CO 2 in poultry barns
Contributor(s):: Berg, C., Yngvesson, J., Nimmermark, S., Sandstrom, V., Algers, B.
In Sweden, laying hens are killed using the following methods: (i) traditional slaughter; (ii) on-farm with CO 2 in a mobile container combined with a grinder; or (iii) with CO 2 inside the barn. The number of hens killed using the latter method has increased. During these killings a veterinarian...
There's a rat in my room! Now what? Mice show no chronic physiological response to the presence of rats
Contributor(s):: Meijer, M. K., Loo, P. L. P. van, Baumans, V.
In general, guidelines on housing and care of animals in the laboratory state that rats and mice should not be housed in the same room. Mice may perceive rats as predators. Although one theory says this can cause stress, there is little scientific evidence to support this theory. In the wild,...
Using data collected for production or economic purposes to research production animal welfare: an epidemiological approach
Contributor(s):: Dewey, C., Haley, C., Widowski, T., Friendship, R., Sunstrum, J., Richardson, K.
Epidemiologists use the analyses of large data sets collected for production or economic purposes to research production nonhuman animal welfare issues in the commercial setting. This approach is particularly useful if the welfare issue is rare or hard to reproduce. However, to ensure the...
Effect of gestation management system on gilt and piglet performance
Contributor(s):: Muns, R., Manzanilla, E. G., Manteca, X., Gasa, J.
Individual gestation housing of pregnant sows in stalls from four weeks after mating is banned in the EU. Two experiments were conducted to study the effect of two gestation management and housing systems (STALL: gilts housed in stalls and PEN: gilts loose-housed in pens with increased feed...
