Farm Animal Behaviour and Welfare – Third Edition

Description of the species-typical and abnormal behavior of farm animals. Wool-pulling is generally performed by the most dominant sheep and is directed at subordinates. The sheep which receive most wool-pulling are usually those which are lowest in the social hierchy...

Effects of rearing conditions on feather pecking in laying hens

Experimental results indicate that feather pecking is a from or redirected ground pecking. Litter-reared birds had significantly less feather damage [suggesting that they engaged in less feather pecking] than goups reared on wire floor. The addition of grain positively affected...

Effect of space allowance on behavioural restriction and synchrony in hens

Frequency of preening and walking increased linearly with increased space; cage-pecking, bill-wiping, vacuum dust-bathing and scratching also tended to increase. Vigilance, jostling, inactivity and eating showed a decrease. .. Jostling indicated that birds were attempting to feed in synchrony, but...

The 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.

Rearing conditions and needs for space and litter in laying hens

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...
