Opportunity for interaction as reinforcer in a T-maze

Used 2 forms of handling as reinforcement in a 'T' maze for 34 male Sprague-Dawley albino rats. In a 12-day experiment, those receiving gentling learned to avoid reinforcement, while those receiving fondling learned to obtain it. In a 6-day follow-up,...

Attenuation of gastric lesions by psychological aspect of aggression in rats

In a study with 80 male albino rats, Ss that fought with each other in response to electric shock showed reduced gastric lesions in comparison with Ss that received the same shocks alone so that fighting behavior did not occur....

A comparative study of the well-being of piglets reared conventionally and in cages

This study is a comparison between two types of housing for piglets: one type including a great variety of stimuli and which can therefore be called a rich environment, the other type apparently being monotonous with very few stimuli for...

The interactions of cage size, cage level, social density, fearfulness and production of Single Comb White Leghorns

Hens housed in the top row of a double-tier caging system appeared more fearful than those caged in the bottom row.

Adaptation of the glucocorticosterone response to novelty

Novelty of the environment is a powerful stimulus to activate the pituitary-adrenal axis. With respect to adaptation of the response to the novel environment, the present findings suggest that more than 2 hr and up to 4 hr is required...

Loudness level and frequency content of noise in the animal house

For a proper evaluation of the physical environment of laboratory animals we should know the loudness level (dB) and frequency (Hz) content of the noise in the animal house (Pfaff, 1974). Physical measurements are necessary since comparison of the threshold...

Some behavioral and physiological changes in pregnant goats and sheep during adaptation to laboratory conditions

Tame sheep and goats have more normal serum concentrations of cortisol than untame animals. They also do not show elevations in heart rates and plasma cortisol concentrations when they are handled. The adjustment to the stress associated with experimental conditions...

Incidence of pup mortality in the rat with particular reference to nesting material, maternal age and parity

Better breeding results were obtained when animals had access to woodwool instead of paper tissue as nesting materials. With paper tissues for nesting purposes 60% of the young were lost compared with 18% with woodwool.
