White Blood Cell Counts, Parasite Prevalence, and Plasma Cortisol Levels of Dogs in a County Animal Shelter: Changes over Days and Impact of a Program of Repeated Human Interaction
Contributor(s):: Emily S. Dudley
Animal shelter housing is highly stressful for a dog, compromising welfare and leading to undesirable behaviors and unknown health consequences. We documented the changes in circulating numbers of white blood cells, plasma cortisol, and fecal parasite shedding of dogs housed for 10 days at a...
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)...

With the increasing number of pets in home the human-animal relationship is increasingly close and care about control disease growing. Ivermectin (IVM) is frequently used because its proven safety. IVM is recommended for the treatment of demodectic scabies and prevention of heartworm in dogs, but...
Cortisol levels in dolphin Tursiops truncatus interactive programs linked to humanNiveles de cortisol en delfines Tursiops truncatus vinculados a programas interactivos con humanos
Contributor(s):: Sanchez Okrucky, R., Morales Vela, B.
Understanding the physiological changes in animals during physical activity to improve animal welfare has become increasingly important in animal collections that remain under human care. To date, the effect of interactive programs on dolphins under human care has not been evaluated, for that...

Fleeing from fleas on your cat, dog, or you
Contributor(s):: Robert G. Holmberg
Fleas are small, laterally flattened, wingless insects that suck blood from warm-blooded animals. There are about 2,500 species. Most are parasites of mammals; about 100 species feed on birds. In North America, 19 species bite humans.
Positive reinforcement training for blood collection in grizzly bears ( Ursus arctos horribilis) results in undetectable elevations in serum cortisol levels: a preliminary investigation
Contributor(s):: Joyce-Zuniga, N. M., Newberry, R. C., Robbins, C. T., Ware, J. V., Jansen, H. T., Nelson, O. L.
Training nonhuman animals in captivity for participation in routine husbandry procedures is believed to produce a lower stress environment compared with undergoing a general anesthetic event for the same procedure. This hypothesis rests largely on anecdotal evidence that the captive subjects...

Study on blood physiology characteristics in working dogs
Contributor(s):: Yang, JiaQiang, Cao, JingFeng, Du, XiaoPeng, Kong, XiaoYan, Yan, DaWei
Adult working dog has to do a lot of intense physical training every day. The blood physiology and hemorheological indexes were measured in three adult working dogs (Kunming, German shepherd, Belgian malinois) and one indigenous breed in Kunming. The results showed that the number of red blood...
Comparison of stress exhibited by cats examined in a clinic versus a home setting
Contributor(s):: Nibblett, B. M., Ketzis, J. K., Grigg, E. K.
Serum cortisol levels, physiological parameters and behavior were used to assess stress experienced by cats examined using equivalent low stress handling techniques in two different environments: their home and an idealized veterinary clinic setting. Healthy cats ( n=18) were examined in a...
Assessment of aversion and unconsciousness during exposure to carbon dioxide at high concentration in lambs
Contributor(s):: Rodriguez, P., Dalmau, A., Manteca, X., Litvan, H., Jensen, E. W., Velarde, A.
The most widely used stunning method in sheep is electrical. However, in lambs, this method leads to rupture of the blood vessels, provoking ecchymoses. In pigs ( Sus scrofa), the use of CO 2-stunning systems has increased in popularity due to positive effects on meat quality and animal welfare...
Pinch-induced behavioural inhibition (clipthesia) as a restraint method for cats during veterinary examinations: preliminary results on cat susceptibility and welfare
Contributor(s):: Nuti, V., Cantile, C., Gazzano, A., Sighieri, C., Mariti, C.
Cats are often subjected to minimally painful or forced procedures during routine clinical practice, which can be poorly tolerated, leading veterinary surgeons to need to offer physical restraint, usually aided by an assistant. The aim of this study was to assess the effectiveness and ultimate...
Perceiving emotions in human-human and human-animal interactions: Hemodynamic prefrontal activity (fNIRS) and empathic concern

Social group formation and genetic relatedness in reintroduced Asian elephants ( Elephas maximus) in Thailand
Contributor(s):: Thitaram, C., Dejchaisri, S., Somgird, C., Angkawanish, T., Brown, J., Phumphuay, R., Chomdech, S., Kangwanpong, D.
Captive-held elephants were recruited from several parts of Thailand and released as part of a reintroduction project. Wild elephants with a herd matriarch generally contain the same matrilineal line and are genetically related. However, reintroduced elephants are less likely to be related, but...

Contributor(s):: Rua, M. A. S., Quirino, C. R., Bastos, R., Bartholazzi Junior, A., Santoro, P. N., Ribeiro, M. da S., Matos, L. F., Barreto, M. A. P.
Assessing the sexual behavior of stallions is extremely important because sexual behavior is linked to reproductive efficiency. The objective of this study was to evaluate the sexual behavior, testosterone concentration and libido of Mangalarga Marchador stallions from northern Rio de Janeiro...
Welfare outcomes for 3- and 6-month-old beef calves in a tropical environment castrated surgically or by applying rubber rings
Contributor(s):: Petherick, J. C., Small, A. H., Reid, D. J., Colditz, I. G., Ferguson, D. M.
Castration of cattle using rubber rings is becoming increasingly popular due to the perceived ease of the procedure and greater operator safety when compared with surgical castration. Few comparative studies have investigated the effects of different castration methods and calf age on welfare...

Contributor(s):: Jensen, M. B., Pedersen, L. J., Theil, P. K., Knudsen, K. E. B.
Fibrous diets and the provision of straw have been suggested to reduce feeding motivation in pregnant sows. The present experiment investigated the separate and interactive effects of a fibrous diet and ad libitum access to straw on feeding motivation, oral behaviour and plasma levels of...

Contributor(s):: Roy, R. C., Cockram, M. S., Dohoo, I. R., Ragnarsson, S.
There is interest in the transportation of horses ( Equus caballus) to slaughter and a need to assess the welfare implications of this practice. Forty-six loads of 7-35 horses transported for 0.33 to 3.10 h to a slaughter plant in Iceland were studied. Adults and foals were transported together...
