Response of adult New Zealand white rabbits to enrichment objects and pair-housing
The high level of interaction [by single-housed rabbits with a gnawing stick, a wooden toy or a brass wire ball] indicated that the rabbits were interested in all the objects. The female pair-housed rabbits spent 88% of the observation intervals...

Read MoreBehaviour of kennelled dogs
Group-housed dogs were not only able to interact socially but also spent more time investigating the floor of their pens. Small pens were associated with reduced normal locomotion, and stereotyped circling rather than pacing.

Reducing the [barren] space allowance from 0.99 to 0.62 sq.m per lamb reduced feed intake and average daily gain. .. There was no effect of pen size on plasma epinephrine, norepinephrine or cortisol concentrations. .. The results show that the...

Read MoreThe interaction of humans with food animals: Making husbandry a science
The effects of good human/animal interactions include improved growth and immune response in chickens, and fewer problems in the milking parlour in dairy cattle. Negative handling of pigs has resulted in increased adrenal activity, poorer growth and reduced reproductive performance.

If dogs are not provided with an adequate early experience of humans they will later be fearful of people and as a result can be difficult to handle.

Straw in a rack provided a stimulus and outlet for rooting and chewing, with a resulting reduction in such activities directed at pen-mates.

Many results show that hens in battery cages show abnormal behaviour indicative of frustration. The fact than none of the single factors studies [space, litter] seem to be solely responsible for this frustration may indicate that what is lacking in...
