Effects of pecking incentives during rearing on feather pecking of laying hens

The provision of grain or other objects - which encourage pecking behaviour - during rearing reduces the incidence of feather pecking when the animals are mature.

Communication between rats of experiment-induced stress and its impact on experimental results

A group of lemurs (Lemur catta, Eulemur fulvus myottensis): Activities during the day, usage of structures

Both species prefer horizontal structures and forked branches, but vertical structures are also important. All different kinds of structures should be offered at different heights.

Task-directed and recreational underwater swimming in captive rhesus monkeys (Macaca mulatta)

Facilitating thermoregulation and increasing [solitary and social] play are two reasons to consider a swimming facility to be a cheap and clean environmental enrichment.

Two squirrel monkey toys

We describe two enrichment devices [suspended chain and rings placed on cage floor] successfully introduced to singly-caged male squirrel monkeys to increase cage complexity and foster manipulative activities.

Of mice and kin: The functional significance of kin bias in social behaviour

Mice tend to be intolerant of same sex partners at the time of puberty. It is, therefore good advice to establish same sex groups well before the onset of puberty.

The preparturient behaviour of sows in enriched pens and the effect of pre-formed nests

Nest building is highly motivated behaviour in sows. Nesting material appears to be a key factor both in the regulation and performance of the behaviour. The study demonstrated that domestic sows housed in enriched pens display nest building behaviour which...

Welfare of laying hens in cages and alternative systems: Environmental, physical and behavioural aspects

There are many different characteristics of housing systems which affect the welfare of laying hens, particularly because welfare itself has many diverse aspects. When cause and effect relationships between systems and welfare are assessed, it is evident that no system...

Teat stimulation and milk production in early lactation of sows

Suckling piglets subjected to continuous loud noise performed less teat stimulation and the milk production of the sow was less.
