Baseline information on demographics and practices on semi-intensive free-range egg farms with an outdoor stocking density of ≤1500 hens/hectare in Australia is presented. Free-range egg production is changing the structure of the egg industry in Australia and a broad variety and tiers of...

Zebrafish (Danio rerio) have proven their efficiency as an animal model for genetics and development, but their nutrition and housing requirements continue to elude researchers. Diet and housing density were predicted to affect weight change and reproductive success in 120 days postfertilization...

Aims: In recent years, with the improvement of traffic conditions, alargenumber of Apis mellifera apiaries migrate from all parts of the country to Yunnan for beekeeping every year. This study aims to clarify the impact of stocking density of A. mellifera as an alien bee species on the species,...

Bumble bees are key pollinators for wild and managed plants and serve as a model system in various research fields, largely due to their commercial availability. Despite their extensive use, laboratory rearing of bumble bees is often challenging, particularly during the solitary phase queens...

Honey bees live in colonies containing tens of thousands of workers that coordinate their activities to produce efficient colony-level behavior. In free-foraging colonies, nest bees are entrained to the forager daily phase of activity even when experiencing conflicting light-dark illumination...

Background: Recognising pain in donkeys is challenging because they are stoic. Objectives: To identify the responses of donkeys before and after surgical pain. Study design Prospective, short-term longitudinal pre- and post-intervention observations. Methods: Forty adult donkeys underwent surgical...

This study evaluated diets including whole or peeled (legs removed) crickets (Teleogryllus testaceus) in terms of diet digestibility, growth and nitrogen retention, using pigs as an animal model. The experiment included three iso-nitrogenous diets (18.4% crude protein) including either whole...

Domestic donkeys descended from wild asses, adapted to the semi-arid climates of Africa, whereas domestic horses originate from more temperate areas of Eurasia. Despite this difference in evolutionary history, modern domestic equids can be found throughout the world, in a wide range of conditions,...

The mass rearing of insects as animal feed is a new and rapidly growing component of circular agriculture, which offers the opportunity to develop it in such a way that it promotes insect health and welfare. Behaviour is an important indicator of animal performance and welfare. In this review, we...

Pasture access is key to horse welfare, but during summer biting insects can cause discomfort and lead to health issues related to transmission of diseases and allergies. To measure the level of discomfort and whether access to shelters or other indoor areas may help prevent biting insect nuisance, ...
