	Title	Age-related changes in taste and gustatory response and feeding behaviour in the stabled horse			Type	Book Chapter
	Year		Publication		Abbreviated Journal
	Volume		Issue		Pages
	Keywords
	Abstract	There is a paucity of research relating to the anatomy and physiology of gustation and olfaction in the horse. Moreover, whilst an age-related decline in gustation and olfaction has been recorded in humans, no such study has been conducted in the horse. The horse is reliant on gustation and olfaction to make appropriate decisions relating to both short and long term diet selection and thus, any compromise in function, has implications for food intake and potentially welfare. The principal aim of this study was to establish if, and to what extent, taste andgustatory responses are affected by age in the horse. Horses were allocated to the age groups Young (2-5 years), Middle (8-14 years) and Old (16 plus years) for the study of taste (n=18) and to Young (4-6 years), Middle (10-14 years) and Old (16 plus years) for the study of gustation (n=18). Individual taste responses and gustatory responses (taste in the absence of additional olfactory cues) were identified using two-choice preference testing and monadic testing. Statistical analysis was conducted using Minitab 14.0 and behaviour data was analysed using The Observer 5.0 (Noldus, Netherlands). No effect of age on taste response or gustatory response was recorded.

	Title	[Phylogeny, form and function of canine teeth in the horse]			Type	Journal Article
	Year	2003	Publication	Anatomia, histologia, embryologia	Abbreviated Journal	Anat Histol Embryol
	Volume	32	Issue	4	Pages	212-217
	Keywords	Animals; Cuspid/anatomy & histology/radiography; Evolution; Horses/anatomy & histology; Male; Phylogeny; *Social Dominance
	Abstract	The canine teeth of the horse developed phylogenically from the simple, pointed, short-rooted tooth form of the leaf eating, in pairs living, Eocene horse Hyracotherium and served up to the Oligocene as a means of defense (self preservation). In the Miocene the living conditions of the Merychippus changed and they took to eating grass and adopted as a new behavior the life in a herd. The canine teeth possibly played an important role in fights for social ranking; they changed from a crown form to knife-like shape. In the Pliohippus the canine tooth usually remained in male horses and since the Pliocene, it contributed to the fights between stallions, to ensure that the offspring only came from the strongest animals (preservation of the species). Form and construction of the canine tooth are described and discussed in detail under the above mentioned phylogenic and ethologic aspects.

	Title	Effect of meal frequency on fluid balance and behavior of ponies			Type	Journal Article
	Year	1988	Publication	Physiology & behavior	Abbreviated Journal	Physiol. Behav.
	Volume	42	Issue	5	Pages	401-407
	Keywords	Animals; Behavior, Animal/physiology; Blood Proteins/analysis; Eating; Female; Hematocrit; Horses/blood/physiology; Osmolar Concentration; Water-Electrolyte Balance
	Abstract	Twelve ponies were fed their total daily ration either as one large meal or divided into six small meals. Pre- and post-feeding behavior was recorded six times a day. Blood samples were taken for 30 min before and two hr after the meal. Plasma protein increased from 7.0 to a peak of 7.3 g/dl with small meals and from 7.3 to 8.1 g/dl with large meals, and returned to pre-feeding levels by 90 min post-feeding. Hematocrit rose from 33.3 to 34.1% with small meals and from 33.0 to 36.0% with large meals. These rapid and short-lived increases indicate a decrease in plasma volume. Plasma osmolality rose with feeding from 283 to 285 mosmoles/kg with small meals and from 281 to 288 mosmoles/kg with large meals. Water availability had no significant effect on blood changes. Digestibility and rate of passage were measured with chromic oxide, but there were no differences. Vocalizing (neighing) and walking occurred more often before than after feeding, while eating bedding and engaging in other oral behaviors were more frequent after feeding.

	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	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.

	Title	Learning ability of orphan foals, of normal foals and of their mothers			Type	Journal Article
	Year	1982	Publication	Journal of animal science	Abbreviated Journal	J. Anim Sci.
	Volume	55	Issue	5	Pages	1027-1032
	Keywords	Age Factors; Animals; Body Weight; Dominance-Subordination; Female; Horses/physiology; Learning; Maternal Deprivation; Mothers/psychology
	Abstract	The maze learning ability of six pony foals that had been weaned at birth was compared to that of six foals reared normally. The foals' learning ability was also compared to their mothers' learning ability at the same task; the correct turn in a single choice point maze. The maze learning test was conducted when the foals were 6 to 8 mo old and after the mothered foals had been weaned. There was no significant difference between the ability of orphaned (weaned at birth) and mothered foals in their ability to learn to turn left (6 +/- .7 and 5.1 +/- .1 trials, respectively) or to learn the reversal, to turn right (6.7 +/- .6 and 6.2 +/- .6 trials, respectively). The orphan foals spent significantly more time in the maze in their first exposure to it than the mothered foals (184 +/- 42 vs 55 +/- 15 s. Mann Whitney U = 7, P less than .05). The mothers of the foals (n = 11) learned to turn left as rapidly as the foals (5.9 +/- .7 trials), but they were slower to learn to turn right (9.8 +/- 1.4 vs 6.4 +/- .4 trials, Mann Whitney U = 33, P less than .05), indicating that the younger horses learned more rapidly. There was no correlation between the trials to criteria of the mare and those of her foal, but there was a significant negative correlation between rank in trials to criteria and age (r = -65, P less than .05) when data from the mare and foal trials were combined. The dominance hierarchy of the mares was determined using a paired feeding test in which two horses competed for one bucket of feed. Although there was no correlation between rank in the hierarchy and maze learning ability, there was a correlation between body weight and rank in the hierarchy (r = .7, P less than .05). This may indicate either that heavier horses are likely to be dominant or that horses high in dominance gain more weight. Maternal deprivation did not appear to seriously retard learning of a simple maze by foals, although the orphans moved more slowly initially. The lack of maternal influence on learning is also reflected in the lack of correlation between the mare's learning ability and that of her foal. Young horses appear to learn more rapidly than older horses.

	Title	Stimulation of food intake in horses by diazepam and promazine			Type	Journal Article
	Year	1976	Publication	Pharmacology, biochemistry, and behavior	Abbreviated Journal	Pharmacol Biochem Behav
	Volume	5	Issue	4	Pages	495-497
	Keywords	Age Factors; Animals; Diazepam/pharmacology; Diet; Feeding Behavior/drug effects; Female; Horses/physiology; Male; Promazine/pharmacology; Stimulation, Chemical
	Abstract	In two adult horses doses of 0.02-0.03 mg/kg diazepam, intravenously, increased 1 hr intake 54-75% above control levels. Intake was stimulated when the diet was a high grain, calorically dense one and also when the diet was a high fiber, calorically dilute one. Two young rapidly growing weanling horses showed an even more pronounced stimulation of intake. Following diazepam 1 hr intake was increased 105-240% above control lelvels. Promazine at a dose of 0.5 mg/kg also stimulated intake in adult horses, but not as markedly as did diazepam. A transquilizer and a neuroleptic appear to have a stimulatory eff upon short-term intake in horses.

	Title	Effects of stocking density, flock size and management on the welfare of laying hens in single-tier aviaries			Type	Journal Article
	Year	2006	Publication	British poultry science	Abbreviated Journal	Br Poult Sci
	Volume	47	Issue	2	Pages	135-146
	Keywords	Animal Husbandry/methods; Animal Welfare; Animals; Body Constitution/physiology; Chickens/physiology; Crowding; Feathers; Female; *Housing, Animal/standards; Mortality; Organ Size; Oviposition/physiology; Population Density; Population Dynamics; Random Allocation
	Abstract	Management practices, stocking rate and flock size may affect laying hen welfare but there have been few replicated studies in commercial non-cage systems that investigate this. This study used a broad range of physical and physiological indicators to assess the welfare of hens in 36 commercial flocks. Six laying period treatments were examined with each treatment replicated 6 times. It was not possible to randomly allocate treatments to houses, so treatment and house were largely confounded. Three stocking rates were compared: 7 birds/m(2) (n = 2450), 9 birds/m(2) (n = 3150) and 12 birds/m(2) in either small (n = 2450) or large (n = 4200) flocks. In addition, at 12 birds/m(2), in both small and large flocks, birds were subjected to either standard (SM) or modified (MM) management. MM flocks had nipple drinkers and no nest-box lights. Bone strength, fracture incidence, heterophil:lymphocyte (H:L) ratio, live weight, organ weights, serum creatine, serum osmolality, muscle pH and faecal corticosterone were measured on samples of birds at the end of the rearing period and at the end of lay. During the laying period, mortality, production and integument condition were recorded at regular intervals. Birds housed at 9 birds/m(2) had higher mortality than birds housed at 12 birds/m(2) by the end of lay, but not higher than birds housed at 7 birds/m(2). Birds housed at 7 and 9 birds/m(2) had lower percent liver weight, and worse plumage condition than most of the 12 bird/m(2) treatments. Modified management tended to improve plumage condition. There were no clear effects of flock size on the welfare indicators recorded. At the end of the rearing period fracture incidence was almost negligible and H:L ratio was within a normal range. By the end of lay fracture incidence was 60% and H:L ratio was high, with no treatment effect for either measure. This, together with information on faecal corticosterone, feather loss and mortality, suggests that the welfare of birds in all treatments was relatively poor by the end of lay.
