Abstract |
Stress in humans has been reported to be associated with a decrease in the salivary immunoglobulin A (s-IgA) levels enabling the possible use of s-IgA to assess stress. Prolonged stress, if reliably assessed in a non-invasive manner, may be used to assess animal welfare. This study analysed groups of dogs undergoing physical and temperamental training and s-IgA levels were measured by rocket immunoelectrophoresis in prospective samples. Behavioural assessment was carried out and cortisol levels in saliva were measured by ELISA. A significant negative correlation (P < 0.007) between the logarithmic cortisol concentrations and s-IgA levels in saliva was recorded. The behavioural assessment of the dogs agreed well with the biochemical markers. It is concluded that IgA levels in saliva may be a useful marker of dog well-being and that stress results in decreased s-IgA levels. |

Abstract |
Successful management of captive populations of wild animals requires effective control of reproduction. Contraception is one tool for controlling reproduction of animals in zoos; however, the options available to the animal manager are limited. Contraceptives vary in efficacy, reversibility, and side effects, and thus may not be suitable for widespread use. One consideration when selecting a contraceptive is its potential for side effects on behavior, especially given the fact that reproduction plays such a prominent role in the biology of any species. To date, there have been few evaluations of contraceptives for behavioral effects, and those that have been conducted have focused on hormone-based contraceptives. This study sought to evaluate a novel method of population control, immunocontraception, for behavioral effects in a population of feral horses. Porcine zona pellucida (PZP) immunocontraception prevents fertilization of ova and does not alter normal hormone secretion patterns. It therefore should leave the animal behaviorally intact in terms of reproductive behavior. The study examined the behavior of 43 sexually mature mares on Assateague Island during the 1997 breeding season and, with help from Earthwatch volunteers, collected observations over a 3-month period. The study found no significant differences between treated and untreated mares in general activity budget, aggression given or received, and spatial relationships relative to the stallion. These preliminary findings indicate that PZP contraception seems to have no acute behavioral effects on the behavior of individuals. The study findings also suggest that PZP could be a desirable and effective management tool for captive species in which social behavior plays an integral role in group dynamics. Analyses of group level effects and population level effects are continuing. |

Abstract |
The relationship between social behaviour and skin injuries (caused by horns) of loose housed horned cows was investigated on 35 dairy farms. While the frequencies of two agonistic behaviour elements (push and chase away) were positively correlated with the occurrence of skin injuries, the frequencies of butting and homing were not. Butting appears to have an ambivalent motivation, in that its occurrence is correlated positively both with agonistic behaviour and with social licking. Horning showed a positive correlation with social licking only. Four groups of husbandry conditions that may be associated with the occurrence of social behaviour and of injuries were distinguished: i) herd management, with variables including problem solving management by the farmer, integration of new cows, and dealing with periparturient and oestrus cows; ii) human-animal relationship, with variables including ability to identify individual cows, frequency of brushing the cows, number of milkers, and frequency of personnel changes; iii) animal characteristics, with the variable of herd size; and iv) stable characteristics, with the variable of space per cow (m2). The relevance of the husbandry variables investigated here had been confirmed in a previous stepwise regression analysis (Menke 1996). The variables for herd management and human-animal relationship conditions correlated in a consistent way with the occurrence of agonistic behaviour and/or of injuries, while most of them also correlated in the opposite direction with the occurrence of social licking. Herd size correlated positively with agonistic behaviour, but negatively with social licking. Space per cow correlated negatively with agonistic behaviour and injuries. In more than 70 per cent of the herds investigated, the levels of agonistic behaviour and of skin injuries were low, implying that horned dairy cows can be kept with less risk than is often assumed. We argue that such risks strongly depend on management factors that can be improved. |

Abstract |
It is believed that environmental enrichment techniques can play an important part in creating suitable captive environments for horses. There has, however, been little scientific investigation into the effectiveness of 'stable-toys' which claim to reduce the performance of equine stereotypies. This study investigated the effect of a foraging device known as 'The Equiball' on equine stereotypies. Six horses were given their evening feed in an Equiball, and the occurence of stereotypic behaviour recorded using scan sampling of video observations. Pre-enrichment, horses spent a mean(SD) of 5.27 ? 8.17 per cent of their time in the stable performing stereotypies; and significant individual variation in mean time performing stereotypic behaviour was found (P < 0.05). Several peaks in stereotypy over the day were found, the two main ones corresponding to the times before feeding. A reduction in stereotypic behaviour in five horses, and a small increase in stereotypic behaviour in one horse was observed during enrichment. During enrichment, there was an overall trend for stereotypic behaviour to decrease (P < 0.1). When used in conjunction with other measures such as behaviour therapy, companionship, increased exercise, and so on, the Equiball may help to create an environment less likely to lead to the development of stereotypic behaviours. |

Abstract |
'Mindreading' or theory of mind (ToM) refers to the capacity to attribute mental states to others. This ability is regarded as a critical component of what has, to date, exclusively characterized the advanced social cognition displayed by humans. The false belief task is a key test for ToM in different animal species. On a standard non-verbal false belief task, humans pass from age 4, whereas non-human primates consistently fail. Neuroanatomical and behavioural evidence for dolphins, however, indicates that they are capable of passing ToM tasks. The current paper represents a synthesis of the relevant dolphin research on neocortical evolution and non-invasive behavioural tests of precursors for ToM and the attribution of beliefs. The success of dolphins on attribution of belief tasks, in the absence of learning or cueing, indicates that they are capable of 'mindreading'. What are the implications of animal 'mindreading'? ToM tasks probe for reflexive consciousness and, by this criterion, dolphins may display reflexive consciousness. The implication of this conclusion is that future behavioural studies of social cognition will have considerable ethical and legal implications for animal welfare. |
