Title Feeding and drinking behavior of mares and foals with free access to pasture and water Type Journal Article
Year 1985 Publication Journal of animal science Abbreviated Journal J. Anim Sci.
Volume 60 Issue 4 Pages (down) 883-889
Keywords Animals; *Drinking Behavior; *Feeding Behavior; Female; Horses/*physiology; Male; Poaceae; Seasons; Temperature; Time Factors
Abstract The feeding and drinking behavior of 11 mares and 15 foals living on pasture with free access to water was recorded during 2,340 15-min focal samples taken over 2 yr. Lactating mares on pasture spent about 70% of the day feeding. Foals began feeding on their first day of life. As they grew older, they spent progressively more time feeding, but still spent only 47 +/- 6% of the time feeding by 21 wk of age. Foals fed primarily during the early morning and evening. While grass formed the major proportion of the diet of both foals and mares, they also ate clay, humus, feces, bark, leaves and twigs. Almost all feeding by foals was done while their mothers were feeding. Movement to water sources was frequently, but not invariably, carried out by an entire herd. Frequency (P = .005) but not duration (P greater than .05) of drinking bouts by mares increased as the temperature increased. Frequency was greatest at 30 to 35 C, at which temperature mares drank once every 1.8 h. Frequency of drinking varied with the time of day (P less than .01), being rarest during the early morning (0500 to 0900 h eastern daylight time) and most frequent during the afternoon (1300 to 1700 h). Drinking by foals was very rare. The youngest age at which a foal was observed to drink was 3 wk, and 8 of 15 foals were never observed to drink before weaning.

Title The ontogeny of flehmen in horses Type Journal Article
Year 1985 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 33 Issue 3 Pages (down) 739-745
Keywords
Abstract Flehmen behaviour in Welsh pony (Equus caballus) mares and foals living on pasture was observed during 807 h of focal sampling. A series of flehmens performed at one site was defined as a flehmen incident. Colts exhibited flehmen incidents and performed flehmen more frequently during an incident than did fillies or mares. Filies exhibited flehmen incidents more frequently than did mares, but did not flehmen more frequently during an incident. Colts exhibited a peak frequency of performing flehmen and of flehmen incidents during weeks 1-4 with a subsequent linear decrease in frequency up to weeks 17-20. Usually, flehmen occurred without the subject having had direct contact of the nostrils, lips, or tongue with a possible stimulant. Twenty-six per cent of the flehmen incidents occurred during or after urination by another pony. Seven per cent of the incidents occurred during or after urination by the pony showing flehmen.

Title Vasopressin in dehydrated and rehydrated ponies Type Journal Article
Year 1989 Publication Physiology & behavior Abbreviated Journal Physiol. Behav.
Volume 45 Issue 3 Pages (down) 659-661
Keywords Animals; Behavior, Animal/*physiology; Dehydration/*blood; Drinking Behavior/*physiology; Female; Horses/*blood; Osmolar Concentration; Reaction Time; Time Factors; Vasopressins/*blood
Abstract Six pony mares deprived of water for 24 hours showed significant increases in plasma vasopressin (2.8 pg/ml) and osmolality (9 mosmol/kg). When water was made available the ponies drank rapidly (5 of 6 drank to satiety within 90 seconds) and corrected their fluid deficits precisely. Vasopressin did not return to predehydration levels until osmolality did after 15 minutes of access to water. The horse differs from rodents and humans, but is similar to pigs in that vasopressin levels do not fall before osmolality returns to normal. Oropharyngeal factors, therefore, may not be as important in vasopressin release in horses as in other species.

Title Stable vices and trailer problems Type Journal Article
Year 1986 Publication The Veterinary clinics of North America. Equine practice Abbreviated Journal Vet Clin North Am Equine Pract
Volume 2 Issue 3 Pages (down) 623-633
Keywords Aerophagy/veterinary; Aggression; Animals; *Animals, Domestic; *Behavior, Animal; Fear; Frustration; Habits; *Horses; Locomotion; Mastication; Social Environment; Transportation
Abstract Stable vices include oral vices such as cribbing, wood chewing, and coprophagia, as well as stall walking, weaving, pawing, and stall kicking. Some of these behaviors are escape behaviors; others are forms of self-stimulation. Most can be eliminated by pasturing rather than stall confinement. Trailering problems include failure to load, scrambling in the moving trailer, struggling in the stationary trailer, and refusal to unload. Gradual habituation to entering the trailer, the presence of another horse, or a change in trailer type can be used to treat these problems.

Title Maternal behavior Type Journal Article
Year 1986 Publication The Veterinary clinics of North America. Equine practice Abbreviated Journal Vet Clin North Am Equine Pract
Volume 2 Issue 3 Pages (down) 557-571
Keywords Aggression; Animals; Animals, Wild; Female; *Horses; Lactation; *Maternal Behavior; Pregnancy; *Pregnancy, Animal; Rejection (Psychology)
Abstract Parturition in mares is rapid and is followed by a brief period of sensitivity to imprinting on a foal. There is large individual variation in normal maternal style, but normal mothers actively defend their foal, remain near the foal when it is sleeping, tolerate or assist nursing, and do not injure their own foal. Disturbance of a mare and foal during the early imprinting period can predispose a mare to rejection of her foal; therefore, it should be avoided. There are a variety of forms of foal rejection and numerous etiologies. Therefore, each case should be evaluated individually.

Title The effects of caloric dilution on meal patterns and food intake of ponies Type Journal Article
Year 1985 Publication Physiology & behavior Abbreviated Journal Physiol. Behav.
Volume 35 Issue 4 Pages (down) 549-554
Keywords Animals; Body Weight; *Diet; Energy Intake; *Feeding Behavior; Homeostasis; Horses/*physiology; Male
Abstract In order to determine if horses will increase their intake in response to caloric dilution, four pony geldings were fed ad lib a mixed grain diet either undiluted (3.4 Mcal/kg of digestible energy) or diluted (wt/wt) with 25% sawdust (2.6 Mcal/kg) or with 50% sawdust (1.7 Mcal/kg). The mean daily caloric intake was 17,457 kcal (3.4 Mcal diet), 17,546 kcal (2.6 Mcal diet) and 12,844 kcal (1.7 Mcal). The mean time spent eating was 246 (3.4 Mcal), 351 (2.6 Mcal), and 408 (1.7 Mcal) minutes/day. Meal size increased and meal frequency decreased with increasing dilution. The median long survivorships of intermeal intervals were 6.4 min (3.4 Mcal), 3.95 min (2.6 Mcal) and 4.91 min (1.7 Mcal). Ponies responded to caloric dilution by increasing the volume of intake to maintain caloric intake when the diet had 25% diluent. When the diet was diluted by 50%, intake was increased, but not at a rate adequate to maintain caloric intake. However, the ponies were able to maintain body weight.
