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...
Hunger in pregnant sows: effects of a fibrous diet and free access to straw
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...
Dairy calves' preference for rearing substrate
Contributor(s):: Worth, G. M., Schutz, K. E., Stewart, M., Cave, V. M., Foster, M., Sutherland, M. A.
Traditional substrate types for dairy calves, such as sawdust, are becoming difficult and/or expensive for farmers to obtain in New Zealand. Therefore, there is a need to evaluate alternative rearing substrates that provide an acceptable level of animal welfare. The preference of dairy calves for...
Experimental verification of the effects on normal domestic cats by feeding prescription diet for decreasing stress
Contributor(s):: Miyaji, K., Kato, M., Ohtani, N., Ohta, M.
The objective of this study was to evaluate the effects of diet on the feline stress response by measuring plasma and urinary cortisol. A study diet was developed with a unique combination of nutrients that supports the management of stressful situations. The specific formulation of the diet...
Effects of prepartum housing environment on abnormal behaviour, the farrowing process, and interactions with circulating oxytocin in sows
Contributor(s):: Yun, JinHyeon, Swan, K. M., Oliviero, C., Peltoniemi, O., Valros, A.
We evaluated the effects on sows of prepartum housing environment on bar-biting (BB) behaviour prior to parturition, farrowing duration from first to tenth piglets, litter size, and circulating oxytocin (OT) concentrations during birth of the first five piglets. A total of 35 sows, approximately...
Physiological effects of human-animal positive interaction in dogs - review of the literature
Contributor(s):: Pop, D., Rusu, A. S., Pop-Vancia, V., Papuc, I., Constantinescu, R., Miresan, V.
Positive human-animal interactions (HAI) are known to increase the quality of life in both humans and dogs. Although there are several reviews on the benefits of HAI in humans, there are no reviews on the effects of positive HAI in dogs. Therefore, the aim of this paper is to provide a review of...
Function of tongue-playing of cattle in association with other behavioral and physiological characteristics
Contributor(s):: Ishiwata, T., Uetake, K., Eguchi, Y., Tanaka, T.
To study the function of tongue-playing of cattle, this study observed 71 Japanese Black x Holstein steers after feeding in 2 repetitive experiments. The number of steers who performed tongue-playing did not differ among the 3 levels of environmentally enriched pens. Most (90.6%) performances of...
The effects of chronic exposure to common bedding materials on the metabolic rate and overall health of male CD-1 mice
Contributor(s):: Becker, C. E., Mathur, C. F., Rehnberg, B. G.
Anecdotes and personal Web pages claim that cedar and pine beddings cause respiratory distress in rodents, although no previous research could be found to support these claims. There have, however, been published studies of respiratory distress in cedar and pine mill workers. That research links...
Working with rather than against macaques during blood collection. (Training Nonhuman Primates Using Positive Reinforcement Techniques)
Contributor(s):: Reinhardt, V.
Training macaques to cooperate during blood collection is a practicable and safe alternative to the traditional procedure implying forced restraint. It takes a cumulative total of about 1 hr to train an adult female or adult male rhesus macaque successfully to present a leg voluntarily and accept...
