Includes refinements to diet, bedding or flooring, cage changing, lighting, temperature, noise levels, etc.
For over a century, the practice of deflighting has taken place in zoological collections in order to ensure birds remain in open-topped enclosures. Over time, efforts have been made to improve or develop new (surgical)...
Fala, a four month old cria, presented with signs of lethargy and unwillingness to stand, at times she was laid in lateral recumbancy with her head outstretched. South American camelids are inclined to develop rickets...
Many husbandry routines in zoo herpetology are based on tradition, authoritarianism, anecdote, or speculation. However, relatively few empirical studies underlie many very common practices. We compared growth rates among littermates of Boa constrictor raised under...
We recorded the thermoregulatory patterns of five Aldabra giant tortoises (Aldabrachelys gigantea) (25-193 kg) during spring (ZRH spring trial), after the installation of a heating area (concrete heat pad and basking lamp) at Zurich Zoo...
Many reptiles require ultraviolet-B radiation between 290 and 315 nm (UV-B) to synthesize vitamin D3 and process dietary calcium. In captivity, exposure to too little or too much UV-B can result in health problems such...
Jellyfish are a popular public aquarium species, however, their collection from natural populations is undesirable due to impact on species abundance and bycatch. Thus, a sustainable supply of jellyfish bred in-house would be highly desirable...
It is vital to provide appropriate nutrition to maintain healthy populations in conservation breeding programs. Knowledge of the wild diet of a species can be used to inform captive diet formulation. The nutritional content of...
Icelandic horses are often stabled in loose-housing systems, and to date this type of stabling has not been evaluated with regard to its potential impact on respiratory health. The objective was to assess if differences...
Laboratory mice (Mus musculus) communicate a variety of social messages through olfactory cues and it is often speculated that these cues are preserved in nesting material. Based on these speculations, a growing number of husbandry...
Creep feed intake is variable and may be partly homeostatically and exploratory driven. We studied effects of maternal feed restriction and a ‘play-feeder’ on piglet behaviour and performance. 37 Litters received creep feed in a...
