Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour
Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.
Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...

A multidisciplinary approach to assess the welfare of weaned pigs during transport at three space allowances
Contributor(s):: Sutherland, M. A., Bryer, P. J., Davis, B. L., McGlone, J. J.
Transport can be a stressful experience for pigs, especially in pigs simultaneously experiencing weaning stress. The objective of this study was to use a multidisciplinary approach to assess the welfare of weaned pigs during transport at 3 space allowances. A commercial semitrailer, fitted with...

Contributor(s):: Hawthorne, L.
A 'special feature' article by the Project Coordinator of MIssyplicity, a Genetic Savings & Clone (GSC) project seeking to clone a specific mixed breed dog, named Missy, owned by an anonymous yet wealthy individual.
Cloning companion animals is wrong
Contributor(s):: Bok, H.
"... Cloning is not safe, and it is not widely understood. Nevertheless, I suppose that some extremely compelling reason might justify our cloning animals. However, there is no such justification for the Missyplicity Project." ...
New dog: old tricks
Contributor(s):: Greene, M.
In this article, the author examines the strategy underlying the code of ethical practice established by Genetic Savings & Clone (GSC) as they progressed toward commerical cloning of campanion animals.
Training large macaws for artificial insemination procedures
Contributor(s):: Leblanc, F., Pothet, G., Jalme, M. S., Dorval, M., Bovet, D.
For some endangered parrot species, captive breeding may be the only insurance for their survival. However, many individuals in captivity do not reproduce. Artificial insemination (AI) may help overcome reproductive failures or geographic distance. For semen collection in birds, massage is the...

Human-animal interaction, stress, and embryo production in Bos indicus embryo donors under tropical conditions
Contributor(s):: Macedo, G. G., Zuccari Neto, C. E. S., Abreu, U. G. P. de, Negrao, J. A., Costa e Silva, E. V. da
This study investigated the effect of human-animal interaction (HAI) and the stress response on the quality of embryo production in superovulated Nelore (Bos indicus) cattle, under tropical conditions. Thirty-two females underwent a superovulation protocol for 5 days. Cortisol concentrations were...

A comparison of cell-mediated immune responses in rhesus macaques housed singly, in pairs, or in groups
Contributor(s):: Schapiro, S. J., Nehete, P. N., Perlman, J. E., Sastry, K. J.
A variety of psychosocial factors have been shown to influence immunological responses in laboratory primates. The present investigation examined the effects of social housing condition on cell-mediated immune responses, comparing rhesus macaques (Macaca mulatta) in three housing conditions...
Does in proestrus-estrus hasten estrus onset in does estrous synchronized during breeding season
Contributor(s):: Romano, J. E.
During the breeding season, 68 Nubian goats were synchronized for oestrus with intravaginal sponges impregnated with fluorgestone acetate (FGA, Chronogest, 30 mg; n=36) or medroxyprogesterone acetate (MAP, Sincrocel, 60 mg; n=32). The experiment was performed in two replicates. In each replicate,...
Effect of different rearing systems and pre-kindling handling on behaviour and performance of rabbit does
Contributor(s):: Mugnai, C., Bosco, A. dal, Castellini, C.
The aim of this study was to ascertain how collective cage and pre-kindling handling (training does to go into their own nest) practices, in comparison to standard housing (single cage rearing), modify the behaviour and the performance of rabbit does. To this aim, 40 nulliparous New Zealand White...
Effect of gradual transition from maternal to reconstituted milk on behavioural, endocrine and immune responses of lambs
Contributor(s):: Sevi, A., Napolitano, F., Casamassima, D., Annicchiarico, G., Quarantelli, T., Paola, R. de
18-24 h after parturition, 20 Comisana lambs were separated from their dams and were subsequently offered a commercial milk substitute (Sub) or were subjected to a gradual transition from maternal to reconstituted milk over 10 days (Mix). Lambs had free access to milk for 3 h a day. A further 10...
