Abnormal behavior patterns in rhesus monkeys: Symptoms of mental disease?

This paper describes the morphology of abnormal behavior of rhesus monkeys which had experienced a certain degree of social isolation. Analysis of the morphology of the behavior starts from the hypothesis that abnormal activities should preferably be interpreted as distortions...

Fear and affiliation in domesticated male rats

Unfamiliar conspecifics were just as effective in allaying fear as familiar animals. Even the individually reared rats, unused to other rats, were less fearful with conspecifics than when they were stressed alone. These findings simply attest to the strength of...

The assessment of behavioural needs of pigs under free-range and confined conditions

This study exemplifies how housing conditions can be tailored [outside enclosure with woods, bushes, etc.] to the behavioural needs of pigs and still leave room for economic optimization.

A family system in enriched pens as a novel method of pig housing

A housing system for pig families in enriched pens was designed taking into account the ethological requirements for pig housing previously researched by observing pigs in a semi-natural enclosure. Each pen is composed of nesting, activity and rooting areas and...

Natural sucking performance and age of weaning in zebu cattle (Bos indicus)

The total sucking time and the number of bouts varied significantly in inverse relation to age of the calf, but the duration of a sucking bout was constant at 8 min and independent of age. There was an average of...

Cohesive relationships in a cattle herd (Bos indicus)

Cohesive relationships were studied in a semi-wild cattle herd and traced over periods of three to five years. It became evident that mother cows prefer their female and male progeny over non-related calves as grooming and grazing partners. These associations...
