| Title | Social structure and interactions within groups of horses containing a stallion | Type | Conference Article | ||
| Year | 2008 | Publication | IESM 2008 | Abbreviated Journal | |
| Volume | Issue | Pages | |||
| Keywords | Social interactions,, Stallions, Hierarchy, Icelandic horses | ||||
| 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. |

| Title | The influence of management on horse behavioural reactivity in therapeutic riding programs. | Type | Conference Article | ||
| Year | 2008 | Publication | IESM 2008 | Abbreviated Journal | |

| Abstract | We investigated 8 horses in five therapeutic riding centres situated in San Cataldo (Caltanissetta – I), Nicosia (Catania – II), Pellaro (Reggio Calabria – III), San Gregorio (Catania – IV), Niguarda Hospitals (Milan – V). The managements of the animals were of different typologies: Type 1, Type 2 and Type 3. In type 1 the horses were used for therapeutic riding only. Furthermore intra and interspecific social interactions were not allowed. In type 2 the horses played kinetic activities and made social interactions. In type 3 the horses were free in paddock, as intra and interspecific social interactions were allowed. The centre I, with a management of type 1, housed 1 horse (A1); the centre II, with a management of type 2, housed 1 horse (B2); the centre III, with a management of type 1, housed 1 horse (C1); the centre IV, with a management of type 2, housed 2 horses (D2 and E2); the centre V, with a management of type 3, housed 3 horses (F3, G3 and H3). Breeds of horses were: Anglo-Arab (n°1), Avelignese (n°3), Italian Selle (n°3), draught-horse crossbreed (n°1). They were 2 geldings and 6 females. Their ages ranged from 12 to 23 years. We observed a total of 64 patients affected by different pathologies: autism, motory handicap, blindness and deafness, children“s cerebral paralysis, relational problems, mental deficiency, Down”s syndrome. The horses“ behaviour was observed at rest and during therapeutic activities with these patients. The Heart Rate (HR) was used as physiological parameter for an ethological evaluation, measured by a telemetric heart rate monitor (Polar Horse Trainer). Horses were analysed with a reactivity test for emotional homeostasis evaluation, too. Heart rate values were studied with non parametrical statistical analysis methods. Distinct management typologies provided statistically different basal mean values of heart rate (intergroup and intragroup): Type 1 vs Type 2 (P~0.05) and Type 1 vs Type 3 (P<0.05). The comparison of heart rate during therapeutic activities of diverse management showed the following results: A1 vs B2 (P<0.05), B2 vs C1 (P<0.05), Type 1 vs Type 2 (P<0.01). Different managements, both in the same or different typologies, gave significantly diverse results (A1 vs E2: P~0.05; C1 vs E2: P~0.05; B2 vs E2: P~0.05). This study shows that the statistic differences obtained by therapies with autistic patients derive from management conditions of Type 1. In reactivity test there aren”t any significant differences among the three management typologies. However, we recorded strong variation between medium and maximum values of heart rate, especially in Type 1 and Type 2 of management. These high variations of heart rate indicated fear reaction of the horse to new stimuli. This reaction could lead to dangerous accidents for patients during therapeutic activities. Horses used in therapeutic riding programs must be evaluated before this employment. Horse's behaviour can be assessed by an ethological observation and a reactivity test. Furthermore, the horses must be guaranteed welfare conditions and must live in an environment enriched with sensorial stimuli and respectful of their physiological and ethological needs. |

| Title | A note on behaviour and heart rate in horses differing in facial hair whorl | Type | Journal Article | ||
| Year | 2007 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |
| Volume | 105 | Issue | 1-3 | Pages | 244-248 |
| Keywords | Horse; Hair whorls; Behavioural tests; Reactivity; Heart rate | ||||
| Abstract | The relationship between facial hair whorl position and reactivity, as assessed by behavioural measures (handling score = HS; startle reaction to a suddenly appearing novel object = SR; latency to touch a novel object = LNO) and heart rate measures (mean HR; increase in heart rate = IHR) were studied using 55 Konik horses reared either under conventional stable conditions or in the forest reserve. Horses were classified into four groups according to the whorl position and/or shape: (1) high, single whorl above the top eye line, n = 9; (2) medium, single whorl between the top and the bottom eye line, n = 30; (3) low, single whorl below the bottom eye line, n = 10; and (4) elongated or double whorl, n = 6. Horses with a high whorl position demonstrated a lesser degree of manageability as expressed by a lower HS compared to individuals with medium (P = 0.002) or low whorl positions (P = 0.016). Horses with different whorl positions did not differ significantly in their startle response to a suddenly appearing novel object (P = 0.685). The horses with an elongated or double whorl, which appeared only in the forest group, took significantly longer to approach the novel object than horses with medium (P = 0.006) or low (P = 0.005) whorl positions. No significant differences in mean HR and IHR between groups (HR: P = 0.629 and IHR: P = 0.214) were found. In conclusion, this study supports the relationship between the position of the hair whorl on the horses' head and their manageability during handling, as well as the latency to approach an unknown object. | ||||

| Title | Effect of water restriction on equine behaviour and physiology | Type | Journal Article | ||
| Year | 2000 | Publication | Equine veterinary journal | Abbreviated Journal | Equine Vet J |
| Volume | 32 | Issue | 4 | Pages | 341-344 |
| Keywords | Animals; *Behavior, Animal; Blood Proteins/analysis; Energy Intake; Female; Horse Diseases/physiopathology; Horses/*physiology; Osmolar Concentration; Pregnancy; Stress/veterinary; Video Recording; Water Deprivation/*physiology | ||||
| Abstract | Six pregnant mares were used to determine what level of water restriction causes physiological and/or behavioural changes indicative of stress. Nonlegume hay was fed ad libitum. During the first week of restriction, 5 l water/100 kg bwt was available, during the second week 4 l/100 kg bwt and, during the third week, 3 l/100 kg bwt. Ad libitum water intake was 6.9 l/100 kg bwt; at 3 l/100 kg bwt water intake was 42% of this. Daily hay intake fell significantly with increasing water restriction from 12.9 +/- 0.75 kg to 8.3 +/- 0.54 kg; bodyweight fell significantly for a total loss of 48.5 +/- 8.3 kg in 3 weeks. Daily blood samples were analysed; osmolality rose significantly with increasing water restriction from 282 +/- 0.7 mosmols/kg to 293.3 +/- 0.8 mosmols/kg bwt, but plasma protein and PCV did not change significantly. Cortisol concentrations fell from 8.1 ng/ml to 6.4 ng/ml over the 3 week period. Aldosterone fell from 211.3 +/- 74.2 pg/ml to 92.5 +/- 27.5 pg/ml at the end of the first week. The behaviour of 4 of the 6 mares was recorded 24 h/day for the duration of the study. The only significant difference was in time spent eating, which decreased with increasing water restriction from 46 +/- 3% to 30 +/- 3%. It is concluded that water restriction to 4 l/100 kg bwt dehydrates pregnant mares and may diminish their welfare, but is not life- or pregnancy-threatening. | ||||

| Abstract | Various molecular weight hyaluronic acid (HA) preparations have been injected into joints for the treatment of human and equine osteoarthritis. A therapeutic advantage has been claimed for commercial products with a molecular weight in the range found in normal synovial fluid (SF), compared to lower molecular weight products. But a correlation between molecular weight and efficacy is not borne out by an analysis of the available literature on clinical results. SF viscosity, HA concentration, HA molecular weight and rate of synthesis in joint disease. It is proposed that the beneficial effect of injected HA in joint disease may be due to pharmacological rather than to physical properties. | ||||
