Abstract: Interventions occur when animals interfere in competitive interactions between two or more individuals. Interveners can alter the nature of the ongoing interaction by targeting one party (attacking, biting) and supporting the other. Three theories have been proposed to account for intervention behaviour: kin selection, reciprocity and direct benefits. The kin selection hypothesis predicts that interveners will selectively support relatives over nonrelatives; the reciprocity hypothesis predicts that when intervener [`]A' supports individual [`]B', later [`]B' will intervene and support [`]A'; and the direct benefits hypothesis predicts that target/support patterns should serve the immediate interests of the intervener. We tested the reciprocity and direct benefits hypotheses by exploring third-party interventions in play fighting among littermates of domestic dogs. Interveners in dyadic play did not preferentially target or support preferred playmates of the intervener. Interveners targeted the dog in the losing role at the time of the intervention, and they did not show reciprocity in support. Taken together, these last two findings suggest that littermates benefit directly and use interventions opportunistically to practise offence behaviours directed at littermates already behaving subordinately. Opportunities to practise targeting in a playful setting may help structure dominance relationships among littermates. Additionally, the tendency for puppies to do what the other is doing (target the dog in the losing role) may pave the way for synchronizing cooperative behaviours during group hunting and territorial defence. The types of behaviours used to intervene changed over development, but the outcome following an intervention remained stable.

Abstract: Lateralized behaviour in the felids has been subject to little investigation. We examined the paw use of 42 domestic cats on three tasks designed to determine whether the animals performed asymmetrical motor behaviour. The influence of the cats' sex and age on their paw preferences was also explored. The distribution of the cats' paw preferences differed significantly between the three tasks. Task 1, the most complex exercise involving retrieval of a food treat from an empty jar, encouraged the most apparent display of lateralized behaviour, with all but one animal showing a strong preference to use either their left or right paw consistently. Tasks 2 (an exercise involving reaching for a toy suspended overhead) and 3 (a challenge involving reaching for a toy moving along the ground) encouraged ambilateral motor performance. Lateralized behaviour was strongly sex related. Male and female cats showed paw preferences at the level of the population, but in opposite directions. Females had a greater preference for using their right paw; males were more inclined to adopt their left paw. Feline age was unrelated to either strength or direction of preferred paw use. Overall, the findings suggest that there are two distinct populations of paw preference in the cat that cluster strongly around the animals' sex. The results also point to a relationship between lateralized behaviour and task complexity. More apparent patterns of lateralized behaviour were evident on more complex manipulatory tasks, hinting at functional brain specialization in this species.

Abstract: Soiled bedding influences cleanliness and disease levels in dairy cows and there is no evidence of an inherent latrine behaviour in cattle. If cows were trained to use a concrete area of the housing system as a latrine, a cleaner bed could be maintained. Thirteen group-housed, 14-16-month-old Holstein-Friesian heifers, were clicker trained with heifer-rearing concentrate pellets as a reward. Training was carried out in four phases. (Phase 1) Association of feed reward with clicker, criterion: 34/40 correct responses. (Phase 2) Simple task (nose-butting a disc) to reinforce phase 1 association, criterion: 17/20 correct responses. (Phase 3) Association of eliminative behaviour with reward where criterion was four sessions with only one incorrect response: criteria for each heifer in phases 1-3 were set using binomial tests. (Phase 4) Shaping eliminative behaviour to occur on concrete. Possible responses were, eliminating on concrete (C) or straw (S), or moving from one substrate to another immediately before eliminating: C --> S, S --> C. Heifers were rewarded for the desired behaviours C and S --> C and ignored when S and C --> S occurred. If learning was achieved, C should increase as C --> S decreased and S --> C should increase as S decreased: tested with Spearman rank correlations. All heifers achieved criterion by day 4 of phase 1 (P = 0.001); day 1 of phase 2 (P = 0.001) and day 10 of phase 3 (P < 0.009). Responses changed throughout phase 3 beginning with (i) looking at the trainer whilst voiding then moving to trainer after the click, and later including (ii) moving to trainer immediately before- or (iii) during voiding. No relationship was found between S and S --> C (rs = -0.14; P = 0.63) or C and C --> S (rs = -0.33; P = 0.25). All group members eliminated more often on concrete (580) than on straw (141) but four heifers with consistently longer lying bouts also showed more C --> S before lying down (Mann-Whitney, P = 0.007). The present study is believed to be the first reported work to show that cattle can be trained to show an awareness of their own eliminative behaviour. This was not successfully shaped to latrine behaviour, however, and it is suggested that floor type may not have been a sufficiently salient cue. Voiding on straw occurred largely with response C --> S (0.73) and general behaviour suggested that this was strongly linked to lying patterns of individual heifers.

Abstract: In 32 Offenlaufställen mit computergesteuerten Abrufstationen wurden die Aufenthaltsdauer
und Besuchshäufigkeit sowie das Droh- und Meideverhalten von 439 Pferden im
Füttererungsbereich erfasst. Je Betrieb erfolgten visuelle kontinuierliche Direktbeobachtungen
nach dem Tortenstückverfahren (6 x 4 Stunden) für je einen 24-Stunden-Tag.
Ziel war die Überprüfung der verschiedenen Bauausführungen der Abrufstationen unter
dem Aspekt der Tiergerechtheit. Eine Einwegstation reduzierte signifikant die Anzahl an Auseinandersetzungen
im Fütterungsbereich. Demgegenüber führten die für das fressende Pferd
tiergerechten Varianten (Fressstand mit Eingangssperre und ohne Austreibehilfe) zu einer
Erhöhung der Besuchshäufigkeit und Aufenthaltsdauer und somit auch zu einer erhöhten
Anzahl an Drohgesten. Doch insgesamt betrachtet, kann die Anzahl an sozionegativen
Interaktionen im Fütterungsbereich der Abrufstationen als relativ gering eingestuft werden.
Da sich außerdem der Betrieb (Management, Fläche, Konzeption) als maßgeblicher Einflussfaktor
auf die überprüften Parameter erwies, dürften die Unterschiede in der Bauausführung
der derzeitigen Abrufstationen für Pferde eher von untergeordneter Bedeutung sein.
[Duration of stay, frequency of visit, threatening gestures and behaviour of avoidance of
439 horses was observed at the feeding area of 32 run-out-sheds. The observation was based
on the method of visual continuously direct watching after the pie chart system (6 x 4 hours)
over a period of 24 hours. The observation should show which construction of the different
automatic feeding systems corresponded best under the aspect of animal welfare.
It was obvious that the one-way-station reduced significantly the number of conflicts
in the feeding area, whereas those systems which are appropriate for the eating horses
(feeding station with access barrier and without stimulation device by electric shock) led
to a higher frequency of visits and duration of stay as well as to more threatening gestures.
Considering altogether, the number of negative interactions in the feeding area of the feeding
systems can be classified as comparatively unimportant. As it showed that the stable
(management, stable area, conception) was of important influence on the surveyed parameters,
the differences between the constructions of feeding stations for horses of present
systems are probably of less meaning.]
