Optimal Husbandry and Breeding Successes of the Grey Slender Loris
Improved husbandry, enclosure design and behavioural enrichment of grey slender loris within successive captive breeding
In July 2008 ZSL London Zoo received one of three breeding pairs of grey slender loris in Europe, for the newly renovated Nocturnal World in the Clore Pavilion. The aim was to breed from them successively to enhance the EEP population level in Europe. To enable the animals to feel comfortable in their enclosure and to be able to perform their extensive behavioural repertoire, we developed a comprehensive husbandry and enrichment schedule that addressed the complex needs of this nocturnal prosimian, especially in terms of advanced behavioural enrichment specific for this species. In addition, we looked at environmental enrichment as a way of increasing wellbeing and welfare and likely breeding success of the group. The first of the births occurred in June 2009 with followed by 8 more in the next 4 years. Not all of these births were from the original pairing; the breeding success allowed formation of a second potential breeding group set up in an off-show area. This pair formed from an elderly male already at London Zoo and the first of the new offspring from the new pair, since then the second breeding group has matched the success of the first. The significant success in continuous breeding from both groups of loris at ZSL London Zoo reflects the high levels of research into ensuring optimal husbandry. At present there are 12 slender loris at London Zoo and recently youngsters have transferred to other EEP zoos. In 2011 the EEP population totalled 26 loris.
