The biological overview, uses in the laboratory, laboratory management and breeding, laboratory procedures, and common welfare problems encountered with the laboratory guinepigs are discussed in this chapter.

Between November 2016 and October 2017, 23 horse transports from 18 collection points to two slaughterhouses in Argentina and one in Uruguay were monitored. The goal of this study was to characterize the current practices in commercial horse transports and to detect potential threats to horse ...

Developing a land sharing strategy requires a thorough understanding of what is the maximum productivity that can be achieved without altering key ecosystem processes. In the central Argentina highlands, Polylepis australis dominates the few remaining patches of forests and its evergreen trees are...

Appropriate management of social groups is one of the greatest challenges that face zoos and aquaria worldwide. To facilitate breeding programmes, particularly in polygynous species, there is a need to house surplus males in bachelor groups, yet for pinnipeds, the social impact of this management...

Tambaqui (Colossoma macropomum) is the main freshwater species produced in South American aquaculture and is also produced in several Asian countries. The objective of the present study was to evaluate the growth and physiology of juvenile Colossoma macropomum submitted to different stocking...

The dourado Salminus brasiliensis is a freshwater species found in major South American rivers and has recently been cultivated in cage systems. As stocking density and handling are known stress factors in cage systems, we studied the combined effect of stocking density (of 30, 150 and 300 fish m...

Captive breeding of peccaries is on the increase in neotropical countries. Few studies, however, have reported behavioural responses of wild animals under farmed conditions. Therefore, the aim of this study was to evaluate the effects of space allowance on the occurrence of social behaviour...

Although the role of livestock in future food systems is debated, animal proteins are unlikely to completely disappear from our diet. Grasslands are a key source of primary productivity for livestock, and feed-food competition is often limited on such land. Previous research on the potential for...

Some consumers in Colombia show a clear preference for purebred dogs. At the same time, there are many abandoned dogs on the streets and in shelters in this country. Previous research has revealed that appearances of the breeds influence the caregivers' (owners') choice. A choice based on...

The Andean bear alopecia syndrome is a progressive and chronic condition documented in ex situ populations. Recent advances focus on treating symptoms, not preventing future cases. We therefore explored the epidemiology of this syndrome through an analysis of husbandry and veterinary conditions of...
