Abstract |
The behavior of mares at foaling and their behavior during subsequent weekly brief separations from their foals was quantified. Thirteen multiparous pony mares were observed for the first 30 min after foaling. Activities directed toward the foal and toward the fetal membranes were recorded. There were 16+/-8 contacts with the fetal membranes, most in the first 10 min post-partum. There were 81+/-12 activities directed toward the foal. There was a downward trend in foal contacts over the first 30 min. Eight of the 13 mares were observed for the 30-60 min post-partum during which licking and touching the foal continued. Only one of the foals suckled in the first 30 min, but half had suckled by 60 min. Ten mares and foals were separated for 5 min each week for 9 weeks. Although mare responses (neighs and steps) decreased with age of the foal, the foals' responses increased from weeks 1 to 2 and then decreased with foal age. This indicates that foal attachment to the mare is not complete until it is 2 weeks old. |

Abstract |
Mares quickly form a bond with their foals, probably within the first hour. They lick the foal usually beginning at the tail end, then the head and later the body of the foal. Licking behavior disappears within the first hours in most mares. Once the bond is formed the mare will let no other foal nurse and stays within a meter of the foal most of the time during the first week. The foal follows her when awake, but when he sleeps she stands over him. As the foal matures the distance the mare maintains from the foals get longer and she may graze as he sleeps. The bond of the mother to the foal gradually weakens as revealed by her response to separation from the foal. Weaning usually takes place shortly before the birth of the next foal. Some mares will attempt to steal foals and this can lead to injury of either the mares or the foal. Because of the strong and exclusive bond of most mares to their foal, foal rejection is especially abnormal. It occurs in some breeds more frequently than others, indicating a heritable component. Arabian mares reject 5% of their foals and other breeds reject less than 2%. There are three types of foal rejection- simple fear of the foal that can be quickly solved by holding the mare so the foal can suckle. The mare learns that nursing is pleasurable. This process usually takes only a few hours of holding the mare because foals suckle so frequently- about four times an hours. The second form of foal rejection is avoidance of tactile stimulation of the inguinal fold. When the foal attempts to suckle he usually strikes that skin fold and causes the mare to cow kick and move away. Desensitization to stimulation of the inguinal fold can solve this problem in a few hours. Treatment is more complex and longer for mares that are aggressive to the foal even when it does not touch them. This type of foal rejection can be treated with drugs that inhibit dopamine such as acepromazine-not the alpha adrenergic agent xylazine. Dopamine inhibits the pituitary hormone prolactin, a putative maternal hormone, which increases milk production. Blocking dopamine will increase prolactin. The mare should always have visual contact with the foal, but be restrained so she can not bite or kick the foal. A pole across the stall confining the mare against a wall is best. Maternal behavior can be induced in non-pregnant mares using injections of estrogen, progesterone, and the dopamine inhibitor sulpiride. Once lactation begins cervical stimulation can be used to elicit maternal behavior toward the next foal the mare sees. |

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. |

Abstract |
Reasons for performing study: Crib-biting is an equine stereotypy that may result in diseases such as colic. Certain breeds and management factors have been associated.
Objectives: To determine: breed prevalence of crib-biting in US horses; the likelihood that one horse learns to crib-bite from another; and owner perceptions of causal factors.
Methods: An initial postal survey queried the number and breed of crib-biting horses and if a horse began after being exposed to a horse with this habit. In a follow-up survey, a volunteer subset of owners was asked the number of affected and nonaffected horses of each breed and the extent of conspecific contact. The likelihood of crib-biting given breed and extent of contact was quantified using odds ratio (OR) and significance of the association was assessed using the Chi-squared test.
Results: Overall prevalence was 4.4%. Thoroughbreds were the breed most affected (13.3%). Approximately half of owners believed environmental factors predominantly cause the condition (54.4%) and crib-biting is learned by observation (48.8%). However, only 1.0% of horses became affected after being exposed to a crib-biter. The majority (86%) of horses was turned out in the same pasture with other horses and extent of contact with conspecifics was not statistically related to risk.
Conclusion: This is the first study to report breed prevalence for crib-biting in US horses. Thoroughbreds were the breed more likely to be affected. More owners believed either environmental conditions were a predominant cause or a combination of genetic and environmental factors contributes to the behaviour. Only a small number of horses reportedly began to crib-bite after being exposed to an affected individual, but approximately half of owners considered it to be a learned behaviour; most owners did not isolate affected horses.
Potential relevance: Genetic predisposition, not just intensive management conditions and surroundings, may be a factor in the high crib-biting prevalence in some breeds, and warrants further investigation. Little evidence exists to suggest horses learn the behaviour from other horses, and isolation may cause unnecessary stress. |

Abstract |
Operant conditioning and two choice preference tests were used to assess the motivation of horses to be released from straight and from box stalls. The motivations for food, a companion, and release into a paddock were compared when the horses had to work for each commodity at increasing fixed ratios of responses (panel presses) to reward in an equine operant conditioning stall. The motivation for food (mean ± SEM = 258 ± 143) responses was much greater than that for either release (38 ± 32) from a straight stall into a large paddock alone or into a small paddock with another horse (95 ± 41) (P = 0.04). When given a two choice preference test between exercise on a treadmill for 20 min or returning to their box stalls, eight of nine horses chose to return to their stalls. In a two choice preference test six of eight horses in box stalls chose to be released into a paddock alone. Horses were given a series of two choice preference tests to determine how long they preferred to be in a paddock. After 15 min in the paddock the horses were re-tested, but all chose the paddock when released into a paddock with three other horses. They were retested every 15 min until they chose to return to their stalls. They chose to stay out for 35 ± 6 min when other horses were in the paddock but for only 17 ± 2 min when they would be alone. When deprived of stall release for 48 h the horses chose to remain in the paddock with other horses for 54 ± 6 min, but showed no compensatory behavior when they were alone (duration chosen = 16 ± 4 min). These findings indicate that horses are not strongly motivated to exercise alone and will choose not to endure forced exercise on a treadmill. The social context of voluntary exercise is important; horses are willing to stay out of their stalls longer if other horses are present and will show compensatory behavior only if other horses are present. These finding have implications for optimizing turnout time for stalled horses. |
