| Abstract | 1. The social relationships in a group of Icelandic horses without a mature stallion were studied. The horses were all familiar to each other. Mutual grooming and play relationships, spatial associations, dominance-subordinate relations and the effect of kinship on these relationships were analysed.TAGSTARTBRTAGEND 2. The social structure was clearly dominated by the behaviour of the adult mares. The horses preferred to form bonds within their social class (sex/age) and they kept close proximity with their friends. The group was effectively divided into two social subgroups, adult mares as one group and adult geldings and sub-adults as another group. The sub-adults and adult geldings formed associations, which were based on mutual grooming and play, while the adult mares did not play. Differences between the sexes were evident. Males played more than the females, had more playing partners and were more popular as playmates.TAGSTARTBRTAGEND 3. Aggression rates were low. The dominance hierarchy was linear. Adult mares ranked higher than adult geldings, sub-adults and the foals. Rank was significantly correlated with age. The closer the adult mares were in rank, the more they groomed with each other. Such relationships were not found amongst the other social group.TAGSTARTBRTAGEND 4. Kinship was calculated between all pairs of animals for up to 4 or 5 generations. Allogrooming and play frequencies and proximity were all positively correlated with kinship. Adult mares, which were close in the dominance hierarchy, were on average more related than those further apart.TAGSTARTBRTAGEND 5. The social relationships in the Icelandic herd were, to some extent, different from relationships reported from unmanaged and feral horse-herds with mature stallions and bachelors. Our results suggest that adult mares groom more in groups without a stallion. Furthermore, they have more preferred partners than in natural harems and their partners are other adult mares, not their weaned offspring as seems to be the case in feral herds. The sub-adults also seem to be more socially active in the absence of stallions. Interestingly, in the Icelandic group, the adult mares showed stallion like behaviours, like mounting and protecting foals. Only by studying the behaviour and the nature of the relationships of horses in groups of different compositions, can we expect to gain a comprehensive understanding about individual social strategies and cognitive capabilities of the species. Such knowledge is valuable for management and welfare of the horse. | ||||

| Title | Controlled Study of Early Handling and Training of Icelandic Foals | Type | Journal Article | ||
| Year | Publication | Abbreviated Journal | |||

| Abstract | Introduction Many scientists agree that information on the learning abilities of horses should be used in developing training methods (Fiske and Potter, 1979; Mader and Price, 1980; McCall, 1990) but nevertheless research where such knowledge is put to the test is limited (Flannery, 1997). Foals that are handled continuously between 4 and 22 months of age were quicker learners and were easier to train than those that got less handling (Fiske and Potter, 1979). The handling involved being lead, brushed, and acclimated to restraint. In some studies more relaxed foals learned more and were easier to train later on than stressed foals (Fiske and Potter, 1979; Heird et al, 1986) while no such correlation was found in another study (Mader and Price 1980). It is commonly believed, and has been established with tests, that younger horses are quicker-learners than mature (Mader and Price, 1980; Houpt, 1982), but the question remains to be answered if a certain age is better than another and if so, if the optimum time differs between breeds. The idea of imprint training (Miller, 2000) is controversial but seems to be popular in the USA. Miller found that foals that had been treated by veterinarians at birth were easier to handle later on. He associated this with what Konrad Lorenz called imprint learning (1937), which involved irreversible learning taking place during a sensitive period early in life. Miller claims that the idea has been tested scientifically but no such papers are covered by Wed of Science. To our knowledge one systematic research has been carried out whose results will be published this year (Jennifer Williams, personal communication). Miller (2000) claims that it is very important to stroke and handle the foals quickly after birth (hence the reference to the imprinting concept) and desensitize them to touch and other interventions. A study by Mal et al (1994) did not support the claim that very young foals are more sensitive to treatment than older foals. It is possible that what we are witnessing when the foals seem relaxed after stroking is not “imprinting” but “learned helplessness”. In Iceland where mares give birth out in the field within the herd (usually herds of mares, sub-adults and sometimes geldings) it is customary not to disturb the mare and foal for the first hours of the foal's life. That fact and the custom in many places to let the foals stay with their dams within large groups in the wilderness from 1-2 months of age till autumn, would mean that continuous handling would not have a practical value for most Icelandic horse owners. We wanted to test the idea that early handling and training of foals should calm the foals considerably and teach them valuable lessons, which would make training later on easier. |
