| Abstract | It is unknown whether or not wild horses“ instinct has remained during their centuries of taming. The knowledge of this matter gives riders the opportunity of knowing more not only about horse behavior but also about horse and rider safety. In the current research we try to study behavior of the two Iranian horse breed (Asil & Caspian) in confrontation with stimuli from predators. We explored which kind of stimuli (olfactory stimuli accompanied by auditory stimuli) affects horses more. We groupe horses based on breed, sex and age. All horses are adult. The test area is a room that equipped with ventilator, speaker, and other facilities that needs. The time spent in the test area varies between 5 and 20 min .The experiments were designed to investigate behavioral responses (locomotive activity ( standing , walk , trot , and exploration), eliminatory behavior (defecation, urination)) and physiological responses (measure and record of adrenalin dosages in blood samples before and after facing to stimuli and measured blood”s glucose and cortisol too) of horses to novel auditory and olfactory stimuli. We explored which kind of stimuli(Olfactory stimuli or auditory stimuli) affects horses more. The experiments were carried out under standardized conditions a total of 60 horses (30 Caspian ponies and 30 Asil horses), of different ages. We investigated how horses respond to two predator animals" (wolf and Iranian leopard) olfactory and auditory stimulus. The olfactory stimuli were: A: Urine /feces stimuli, B: Fur-derived stimuli. And The auditory stimulus were sound of wolf and Iranian Leopard. |

| Title | Social structure and interactions within groups of horses containing a stallion | Type | Conference Article | ||

| Abstract | Earlier research indicates that stallions might either prevent social interactions between mares in their herds directly or indirectly by their presence (Feist and McCullough, 1976; Sigurjonsdottir et al., 2003) The impact of stallions on the social interactions between harem members was studied in 6 groups of Icelandic horses in 2004, 2006 and 2007 for altogether 525 hours. Four of the groups were permanently living together under semi-feral conditions, while two were temporary breeding groups. In addition, temporary and permanent groups were compared and the effect of the stability of the group on the social behaviour of horses was investigated . The results show that stallions seldom intervene directly in social interactions between harem members. However, the hierarchies were less rigid and fewer friendship bonds were found in the groups compared to what has been found in groups without stallions in Iceland. These results give some support to our prediction that the stallion does indirectly suppress social interactions of herd members. The stability of the group was found to affect the aggression rate, since a higher aggression rate was found in the temporary groups compared to the permanent groups. The number of preferred allogrooming partners of the horses was also affected to some extent, as a significantly lower number of allogrooming partners was found in the most unstable group compared to all the other groups. The results have significance for further research in the field of social structure of mammals, and may also be applied in the management of horses and other domestic animals. |
