In this experiment, 64 pairs of animals of the strain C57BL/6J were used. Half of the animals were born and reared until weaning in standard cages and the other half in cages twice the size...
This paper presents a descriptive overview of the evidence obtained thus far for the three proposed uses of reward-related behavior. First, it was shown that previous experiences influence anticipatory behaviour to rewards in rats. This...
We investigated whether housing two female mice in a cage, separated by a grid partition ('living apart together') counters the adverse effects of individual housing on postoperative recovery. Results indicated that socially housed mice appear...
The question was asked: "Rodents are often restrained for data collection procedures, such as blood collection and injection, by coaxing them into tubes, for example syringe cylinders or perspex tubes. What can be done to...
Daily activity rhythms are nearly universal among animals and their specific pattern is an adaptation of each species to its ecological niche. Owing to the extremely consistent nocturnal patterns of activity shown by golden hamsters...
The RSPCA/UFAW Rodent Welfare Group holds a one-day meeting every autumn to discuss current welfare research and to exchange views on rodent welfare issues. A key aim of the group is to encourage people to...
There is strong evidence that sensory experience in early life has a profound influence on the development of sensory circuits. Very little is known, however, about the role of experience in the early development of...
This column discusses the use of novel dietary supplements as environmental enrichment for rodents and rabbits. Items are commercially available from lab animal supply companies. The purpose of enrichment is to encourage behaviors that are...
Human interaction and physical environmental factors are part of the stimuli presented to laboratory animals everyday, influencing their behaviour and physiology and contributing to their welfare. Certain environmental conditions and routine procedures in the animal...
For oral glucose tolerance test (OGTT) in mice, multiple blood samples need to be taken within a few hours from conscious mice. Today, a number of essential parameters may be analysed on very small amounts...
