Abstract |
An early training procedure commonly termed “foal imprint training” is widely promoted in the horse industry. However, there have been no published scientific investigations of its efficacy. This study determined the effects of a training procedure on foals and their reaction to stimuli used in the early training procedure, and to a novel stimulus, at 1, 2 and 3 months of age. Twenty-five foals received a standard training procedure at 2, 12, 24, and 48 h after birth. After the training procedure, the foals received minimal additional handling that included veterinary treatments and occasional relocation. Twenty-two foals born over the same time period served as controls. All 47 (25 trained, 22 control) foals were tested at 1 month of age. Only 20 were available for testing at 2 months of age, and nine were available at 3 months. Percentage change from baseline heart rate, time required to complete exposure to each stimulus (foals that were more reactive took longer) and the behavior of each foal during the introduction of each stimulus were recorded. Overall, the control foals tended to receive lower (better) behavioral scores at 1 and 2 months of age. Foals that underwent the training procedure tended to require less time to complete exposure to the stimulus and had lower heart rates during exposure to the stimuli at 1 and 2 months of age. By 3 months of age, there were no significant differences between trained and control foals for any measures. Early training was not efficacious in this study. |

Abstract |
Crib-biting is a form of oral stereotypy affecting 4-5% of horses. Once fixed, crib-biting is difficult to eliminate by behaviour therapy, however, its performance can be inhibited by collar or surgery treatment (modified Forssell's procedure). Although surgical intervention is widespread, the effects on stress coping in horses have not been studied. In the present study we evaluated changes in behaviour response and heart rate variability in 9 control, 10 crib-biting, 10 collar and 11 surgically treated horses in a feeding stress-test, in which a feeding-bowl was placed in front but out of the reach of the horses, from which tidbits were given 3 times. We found that stress triggers high oral activity, mainly cribbing in crib-biting horses, elevates other forms of oral activities in the inhibited groups and does not affect oral activities of controls. Instead of performing oral activities, control horses tended to target an unavailable feeding-bowl by pawing or head-tossing. Changes in stress level were indistinguishable in controls and crib-biters as heart rate variability returned to baseline values in both groups. In contrast, horses inhibited to perform crib-biting showed elevated stress level throughout the test period. Our results suggest that crib-biting may develop to cope with stress, and such coping function diminishes when inhibited. |

Abstract |
The number of agonistic encounters in a group (frequency per h) and the mean distance to the nearest neighbor in a group (m) were analyzed by a multiple regression on the group size (number of animals in a group) and space allowance (m3 per animal) in each group of calves (6–13 months old, Holstein female and castrated male) and adult cattle (2–12 years old, Holstein heifers and cows or Holstein and Hereford grazing beef cattle). A total of 196 calves and 602 adult animals were used in this analysis. In calves, a significant correlation was found between agonistic behavior and space allowance (r=-0.48, P<0.01), but not between agonistic behavior and group sizes. The mean distance to the nearest neighbor in calf groups increased as the group size decreased and space allowance increased (R2=0.66, P<0.01). In adult cattle, the number of agonistic encounters increased linearly as the group size increased (r=+0.37, P<0.05). The relationship between agonistic behavior and 1(space allowance)2 was significant (r=+0.48, P<0.05). The mean distance to the nearest neighbor tended to increase as the group size decreased and the space allowance increased (R2=0.68, P<0.01). When the space allowance increased beyond 360 m2 per animal, the average distance to the nearest neighbor in the adult group was maintained within the range of 10–12 m. |

Abstract |
Fourteen dogs (7 males and 7 females) were tested for their heart rate (HR) and heart rate variability (HRV) responses in different activities and environmental challenges while their movement was controlled. First, we wanted to compare the dogs? cardiac responses in different body positions (lying, sitting and standing) and during slow walking to reveal their possible influence on HR and HRV. Second, we tested the HR response during an attentive state when the dog was gazing at its favourite toy while remaining in a steady body position. Finally we investigated the heart activity during separation from the owner. We also analysed the individual differences and the influence of gender on the heart responses. We found that the HR increased during periods of increased activity (walking) and was lowest during lying, while it did not differ between sitting and standing. At the same time no changes in HRV were found in the case of different body positions and walking. In contrast, HRV significantly increased when dogs oriented towards their favourite toy, and we found a distinct individual characteristic HR change in this situation compared to the similar body position without the toy being shown. Interestingly during separation from the owner the HR did not increase, but when a strange person was petting the dog, a significant increasing effect was seen in the HR. However the HRV increased only when the petting was discontinued. In general, large individual variation was found with regard to the HR and HRV, while gender did not influence the cardiac activity of the dogs.These results show that body position affected HR significantly in dogs. Further it seems that HRV could be a good indicator of the dog's attentive state. Thus in future studies both the physical and cognitive factors should be given more attention when HR or HRV is investigated as a dependent variable. |

Abstract |
Twelve yearlings were divided into two groups and subjected to two different training schedules: (a) 30min of training daily (the daily trained group); and (b) 30min of training for 4 days, followed by a 3-day rest (the intermittently trained group), in order to compare the effect of two training methods on the ability of the horses to learn to be driven and ridden and to respond to the handlers? cues. The length of this experimental training was 17 days. The first step of training was surcingling and proceeded to lunging, to driving from the ground, and finally to being ridden at a trot on a track. Both groups were tested four times during the experimental period when they were at the same stage of training. They were driven and then ridden at a walk by a rider on a specified course and evaluated. The time to complete the course, accuracy of traveling the course, and heart rate during the test were used as the indicators of success in training. In three out of the four tests, the daily trained group tended to move faster and with more accuracy than the intermittently trained group. It would appear that daily training without a long interruption is more effective for yearlings. |

Abstract |
The aim of this study was to investigate the use of items intended to provide enrichment during turnout, both for individual and group kept horses in an attempt to reduce the amount of passive behaviours. The study was divided into two parts, where study 1 involved eight horses rotated through eight individual paddocks, each containing one of seven enrichment items and one paddock being kept without item, functioning as a control. The horses' item-directed behaviours; passive behaviours or other non-item related activities were scored using instantaneous sampling, every minute for 1h at the beginning and the end of the turnout period. Study 2 involved six horse groups (3-6 horses) and the same scoring methods and ethogram as in study 1. The four items that the horses interacted the most with during study 1 (straw STRA, ball filled with concentrates CBALL, branches BRAN and scratching pole POLE) are investigated in study 2. In addition, the amount of social interactions was recorded. Both horses kept individually (P<0.05) and in groups (P<0.0001) performed significantly more item-directed behaviours towards edible items like STRA and CBALL than other objects. There was, however, no overall relation between the numbers of item-directed behaviours and the number of passive behaviours observed, indicating that the enrichment items did not alone reduce the amount of passive behaviours during turnout periods. Such a reduction was, however, only apparent when horses spent more time eating green leaves growing on the paddock surface (R=-0.97 study 1, R=-0.67 study 2, P<0.0001). Access to STRA in group kept horses also seemed to reduce the amount of agonistic behaviours (P<0.0001). In conclusion, if grass is not available in paddocks, the provision of roughage reduces the amount of passive behaviours in singly kept horses and it also reduces the risk of agonistic interactions between horses kept in group. |

Abstract |
Draft mares and their mule foals were observed from the day of birth to Week 17 of each foal's life. The rate of nursing was recorded and the duration of nursing activity to the nearest second. The rate at which foals engaged in nursing activity varied at each age. The duration of nursing bouts varied slightly as the foals matured. Aggression was recorded during both nursing and non-nursing activity for both the mares and foals. Maternal aggression was highest during nursing activity, especially during the pre-nurse nuzzling period. Maternal aggression increased as the foals matured. Mother-directed foal aggression was primarily in response to maternal aggression. Spatial relationships between each focal dyad were recorded when the foals were upright, not nursing and when they were recumbent. Spatial relationships differed based on the foal's state. The activity in which the mare engaged while her foal was recumbent was recorded. The movements of the mares were also recorded during foal recumbency. Mares approached or maintained their distance from their recumbent foal more than they left their recumbent foal in all weeks of the study, except Week 2. |

Abstract |
From 1989 to 1996, surveys were made in most of the historic range of African wild asses in Somalia, Ethiopia, and Eritrea. From the 1970s to the mid 1990s populations of African wild asses (Equus africanus, Fitzinger, 1857) in Somalia and Ethiopia have declined from approximately 6 to 30 per 100 km2 to 1 or 2 per 100 km2. Given the current IUCN criteria, they are Critically Endangered (CR) and face extremely high risk of extinction in the wild in the immediate future, as their populations have been reduced by at least 80% over the last 10+ years (IUCN, 1994). Basic research is needed on this species as scientific information on its reproductive biology, behavior, ecology, and genetics is very limited. Improved support needs to be provided to existing parks and reserves and new multiple use reserves need to be established. |
