Dominance value was found to be negatively correlated with height at withers (P
Influence of social interaction between rams on their serving capacity
Contributor(s):: Synnott, A. L., Fulkerson, W. J.
The serving capacity (mean number of ejaculates per h) and the preference for particular ewes was recorded on the 1st and 7th day of joining in 8 rams housed individually or in pairs with 12 oestrous ewes. The serving capacity was 50% lower in dominant and submissive rams mating in pairs compared...
Applying the interpersonal circumplex to the behavioral styles of dogs and cats
Contributor(s):: Zeigler-Hill, V., Highfill, L.
The present study examined the viability of the interpersonal circumplex, which was designed to examine human social behavior, as a model for considering the behavioral styles of dogs and cats. This was accomplished by recruiting 555 pet owners to report on the behavioral styles of their pets as...
Characteristics, treatment, and outcome of 99 cases of aggression between dogs
Contributor(s):: Sherman, C. K., Reisner, I. R., Taliaferro, L. A., Houpt, K. A.
99 cases of aggression between dogs treated at the Animal Behaviour Clinic at Cornell University between 1983 and 1993 were analysed. In 73 cases the aggression was a conflict between dogs in the same household, whereas in 26 cases the aggression was directed at non-household dogs. 71% of the...

Effects of separation of resources on behaviour of high-, medium- and low-ranked hens in furnished cages
Contributor(s):: Shimmura, T., Eguchi, Y., Uetake, K., Tanaka, T.
In our previous studies, we demonstrated that dominant hens had priority in using the dust bath, resulted in increased competition for the resource. It seemed that the problem was that the resource was placed on one side of the cage ('localised'). Therefore, we designed a medium-sized furnished...
Social dominance in dairy cattle and the influences of housing and management
Contributor(s):: Wierenga, H. K.
The results of 4 experiments with dairy cows, together with the relevant literature are used to discuss the influence of housing and management on social dominance. In total, 7 groups of dairy cows kept in cubicle houses were studied. Stable dominance relationships appeared to exist, but in 41.1%...

Visual dominance over hearing in feed acquisition procedure of cattle
Contributor(s):: Uetake, K., Kudo, Y.
This paper examined a proximate function of visual and auditory senses and showed visual dominance over hearing in feed acquisition in Holstein cattle; moreover, they seemed to possess a hierarchy of colours in connecting a colour with feed. Subjects (15 calves about 6 months old) were trained,...
Effects of familiarity and relatedness on agonistic pair relationships in newly mixed domestic pigs
Contributor(s):: Puppe, B.
The effects of familiarity and relatedness on agonistic pair relationships (dyads) in different pen regions (pen area or trough area) were studied in 16 groups of newly mixed domestic pigs of similar weight (9 pigs per group) at 12 weeks of age. The agonistic interactions (AI) within 124 familiar...
Heritability of dominant-aggressive behaviour in English Cocker Spaniels
Contributor(s):: Perez-Guisado, J., Lopez-Rodriguez, R., Munoz-Serrano, A.
A total of 51 seven-week-old English Cocker Spaniel puppies were measured for dominant-aggressive behaviour using the Campbell Test. The dogs consisted of a F1 full sibs and half sibs from matings of 4 sires with 10 dams. The purpose of this study was to determine if the variability observed in...
Horse personality: variation between breeds
Contributor(s):: Lloyd, A. S., Martin, J. E., Bornett-Gauci, H. L. I., Wilkinson, R. G.
Anecdotal evidence from horse owners and handlers suggests the existence of breed typical behaviour and personality in horses. This is further supported by current research on heritability of personality characteristics in a range of species. The Horse Personality Questionnaire (HPQ) is a 25-item...
Isolation vs. group rearing in monozygous twin heifer calves
Contributor(s):: Purcell, D., Arave, C. W.
Seven pairs of monozygous (MZ) twin heifer calves were assigned at birth to either isolation or group rearing. The isolation effects on feed intake, social development, survival activity, and learning ability were studied. There were no differences found in the average daily gain between the...
Play behaviour during early ontogeny in free-ranging dogs ( Canis familiaris )
Contributor(s):: Pal, S. K.
Twenty-four free-ranging dog puppies belonging to six litters were observed from birth to 13 weeks of age to study the play behaviour in early ontogeny. Only a single annual breeding cycle with synchronized breeding season was recorded in this study. Mean litter size was 6.67 ranging from 5 to 8...
Social hierarchy affects the adaption of pregnant sows to a call feeding learning paradigm
Contributor(s):: Manteuffel, G., Mannewitz, A., Manteuffel, C., Tuchscherer, A., Schrader, L.
The aim of the study was to test whether adult sows are able to learn an individual acoustic signal for call-feeding in groups supplied with an electronic feeder. Further, we investigated whether and how the social rank of sows affects learning success. Thirty-six sows were examined in 6...
Social influences on the comfort behaviour of laying hens
Contributor(s):: Nicol, C. J.
The influence of the visibility and proximity of familiar pen mates on the behaviour of laying hens was examined. Tail wagging counts increased when pen mates were visible, whilst counts of body shaking and preening increased when pen mates were in close proximity. Head shaking counts were higher...

Group housing of adult silver fox ( Vulpes vulpes ) vixens in autumn: agonistic behaviour during the first days subsequent to mixing
Contributor(s):: Hovland, A. L., Akre, A. K., Bakken, M.
Due to farmed foxes' (Vulpes vulpes) social flexibility and possible motivation for intraspecific contact, group housing may act as an alternative housing procedure. Because initial social contact between silver foxes usually involves agonistic displays as a part of foxes' social dominance...
