Enriched housing reduces disease susceptibility to co-infection with porcine reproductive and respiratory virus (PRRSV) and Actinobacillus pleuropneumoniae (A

Until today, anti-microbial drugs have been the therapy of choice to combat bacterial diseases. Resistance against antibiotics is of growing concern in man and animals. Stress, caused by demanding environmental conditions, can reduce immune protection in the host, influencing the...

Consequences for piglet performance of group housing lactating sows at one, two, or three weeks post-farrowing

Housing lactating sows with piglets in a multi-suckling pen from around 14 days post-farrowing is common practice in Swedish organic piglet production. However, nursing-suckling interaction is less frequent in multi-suckling pens than in individual farrowing pens, thus affecting piglet performance,...

Effect of strain and group size on the response of mice to sconal anaesthesia

The variance of the response to a barbiturate anaesthetic was greater if male mice were caged either singly or in groups of eight than if they were caged in pairs.

An experimental study of intragroup agonistic behaviour in rhesus monkeys (Macaca mulatta)

A significant increase in agonistic behavior occurred when the distribution of the food was restricted, but the amount of food remained normal. Highly significant increases in the frequency of agonistic behavior occurred with the introduction of new monkeys who were...

Effects of adult social experience on patterns of reproductive activity of socially deprived male rhesus monkeys (Macaca mulatta)

The three [single-caged, socially deprived] male subjects represented examples of severely disturbed animals as witnessed by rates of stereotyped behavior (self-aggression, stereotyped locomotion). The problem under investigation involved the extent to which social group experience as an adult could modify...

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,...
