Bandicoot bunkers: training wild-caught northern brown bandicoots (Isoodon macrourus) to use microchip-automated safe refuge

Abstract ContextSoft-release involving supplementary feeding or shelter is commonly used in wildlife reintroduction and rehabilitation projects. However, competition for nestboxes and supplementary feed, as well as predation at feed stations or nestboxes, can reduce the benefits of soft-release. The use of microchip-automated technology can potentially alleviate these concerns, by providing targeted supplementation to only the intended, microchipped animals. AimsWe aimed to train wild-caught northern brown bandicoots, Isoodon macrourus, to use microchip-automated doors to access safe refuge. MethodsBandicoots were trapped from the wild and brought to the Hidden Vale Wildlife Centre, where eight were trained to use the doors in a six-stage process, and then six were trained in a three-stage process, using a peanut butter reward. Key resultsBandicoots learned to use the doors in as few as 3 days. The duration of visits to the door generally increased during training, although the number of visits decreased. ConclusionsThe bandicoots successfully learned to use the microchip-automated doors, which shows that this technology has great potential with wildlife, particularly given the short training times required. ImplicationsThe use of these microchip-automated doors with wildlife has many potential applications, including supplementary feeding stations, nestboxes, monitoring in the wild, as well as enrichment for wild animals in captivity.

Training a wild-born marsupial to use microchip-automated devices: the brush-tailed phascogale (Phascogale tapoatafa) as proof of concept

Microchip-automated feeders and doors allow individualised access to supplementary food and shelter during soft-release of wildlife. A wild-caught brush-tailed phascogale was used to test whether a wild animal could be trained to use microchip-automated devices. The phascogale was trained to use each device in less than a month.

The 'Toolbox' of strategies for managing Haemonchus contortus in goats: What's in and what's out

A dynamic and innovative approach to managing the blood-consuming nematode Haemonchus contortus in goats is critical to crack dependence on veterinary anthelmintics. H. contortus management strategies have been the subject of intense research for decades, and must be selected to create a tailored, individualized program for goat farms. Through the selection and combination of strategies from the Toolbox, an effective management program for H. contortus can be designed according to the unique conditions of each particular farm. This Toolbox investigates strategies including vaccines, bioactive forages, pasture/grazing management, behavioural management, natural immunity, FAMACHA, Refugia and strategic drenching, mineral/vitamin supplementation, copper Oxide Wire Particles (COWPs), breeding and selection/selecting resistant and resilient individuals, biological control and anthelmintic drugs. Barbervax(®), the ground-breaking Haemonchus vaccine developed and currently commercially available on a pilot scale for sheep, is prime for trialling in goats and would be an invaluable inclusion to this Toolbox. The specialised behaviours of goats, specifically their preferences to browse a variety of plants and accompanying physiological adaptations to the consumption of secondary compounds contained in browse, have long been unappreciated and thus overlooked as a valuable, sustainable strategy for Haemonchus management. These strategies are discussed in this review as to their value for inclusion into the 'Toolbox' currently, and the future implications of ongoing research for goat producers. Combining and manipulating strategies such as browsing behaviour, pasture management, bioactive forages and identifying and treating individual animals for haemonchosis, in addition to continuous evaluation of strategy effectiveness, is conducted using a model farm scenario. Selecting strategies from the Toolbox, with regard to their current availability, feasibility, economical cost and potential ease of implementation depending on the systems of production and their complementary nature, is the future of managing H. contortus in farmed goats internationally and maintaining the remaining efficacy of veterinary anthelmintics.
