In laboratory animal husbandry, there is a huge demand for animals that have been kept in disease free conditions and housed in barrier units such as individually ventilated cages. This is very important because when animals are used for scientific research, particularly drug-related research, the animals must provide accurate and valid results.
The European Convention for the Protection of Vertebrate Animals used for Experimental and other Scientific Purposes, sometimes simply referred to as the animal experimentation convention or laboratory animals convention, [1] is an animal welfare treaty of the Council of Europe regarding animal testing, adopted on 18 March 1986 in Strasbourg, and effective since 1 January 1991.
Oligophagy is a term for intermediate degrees of selectivity, referring to animals that eat a relatively small range of foods, either because of preference or necessity. [2] Another classification refers to the specific food animals specialize in eating, such as: Carnivore: the eating of animals Araneophagy: eating spiders; Avivore: eating birds
However, in laboratory studies it is usually necessary to avoid biological variation and to achieve this, laboratory mice are almost always fed only commercial pelleted mouse feed. Food intake is approximately 15 g (0.53 oz) per 100 g (3.5 oz) of body weight per day; water intake is approximately 15 ml (0.53 imp fl oz; 0.51 US fl oz) per 100 g ...
The regulations that apply to animals in laboratories vary across species. In the U.S., under the Animal Welfare Act and the Guide for the Care and Use of Laboratory Animals (the Guide), published by the National Academy of Sciences, any procedure can be performed on an animal if it can be successfully argued that it is scientifically justified.
A radial arm maze allowing animals to choose between 8 variants (e.g. food) that would be placed at the end of each arm. A preference test is an experiment in which animals are allowed free access to multiple environments which differ in one or more ways. Various aspects of the animal's behaviour can be measured with respect to the alternative ...

The sterilized eggs are washed and transferred to a plate of agar containing food for the worms. C. elegans consumes bacteria, so before the eggs can be transferred to the plate, the food must be killed by either heat or irradiation. This method for creating germ-free nematodes has the added benefit of age-synchronizing the worms, so that they ...
