	Title	Mare and Foal Bonding and Problems			Type	Journal Article
	Year	2005	Publication	Clinical Techniques in Equine Practice	Abbreviated Journal
	Volume	4	Issue	3	Pages	228-237
	Keywords	Equine; bonding; behavior; mare; neonatal; foal; inadequate maternal behavior; orphan foal; nurse or foster mare
	Abstract	A number of specific behavioral responses have been identified in mares and foals as the presumed behavioral interactive sequences supporting bonding. With the exception of the severely physically compromised foal, most failures of the mare foal bond appear to result from inadequate behavior of the mare. Six distinct forms of maternal behavior problems include ambivalence of the mare toward her foal, fear of the foal, nursing only avoidance of the foal, extreme protectiveness of the foal that becomes problematic in domestic confinement, savage attack (true rejection), and stealing or adoption of an alien foal. Management of maternal behavior problem cases in which the pair cannot be salvaged include foster (or nurse mares) and hand-rearing methods. Also presented are current practical resources related to managing certain types of inadequate maternal behavior and for rearing the orphaned foal.

	Title	Behavioral retardation in a macaque with autosomal trisomy and aging mother			Type	Journal Article
	Year	1996	Publication	American journal of mental retardation : AJMR	Abbreviated Journal	Am J Ment Retard
	Volume	100	Issue	4	Pages	378-390
	Keywords	Animals; Behavior, Animal; Brain/physiopathology; Female; Hydrocephalus/complications; Longitudinal Studies; Macaca mulatta/genetics; Magnetic Resonance Imaging; Male; Maternal Age; Psychomotor Disorders/etiology; Social Behavior; Trisomy/*genetics; X Chromosome
	Abstract	The social development of a female rhesus monkey (Macaca mulatta) was followed from the day of birth until her death, at age 32 months. The subject, born to an older mother, had an extra autosome (karyotype: 43, XX, +18), an affliction that came about spontaneously. MRI scans revealed that she was also hydrocephalic. Compared to 23 female monkeys growing up under identical conditions, the subject showed serious motor deficiencies, a dramatic delay in the development of social behavior, poorly established dominance relationships, and greater than usual dependency on mother and kin. The subject was well-integrated into the social group, however.

	Title	Maternal investment results in better foal condition through increased play behaviour in horses			Type	Journal Article
	Year	2008	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	76	Issue	5	Pages	1511-1518
	Keywords	Equus caballus; feral horse; maternal investment; play
	Abstract	Play behaviour is widespread in mammals, but benefits to play have been difficult to demonstrate. Physical training is one of the many proposed hypotheses, suggesting that males and females should play differently, that increased maternal investment should lead to increases in play, and that increases in play should result in physical advantages. In a population of feral horses, Equus caballus, males and females did not differ in their play behaviour except that males initiated more of their play bouts than females. Maternal condition influenced play behaviour only in males, with sons of mothers in good condition playing more. However, when we controlled for maternal effects by comparing a son and a daughter of the same mother, daughters played more when their mother was in poor condition and sons played more when their mother was in good condition. Mothers of foals that played more lost more condition. Therefore, the difference in play behaviour could not be explained by offspring sex or maternal condition alone, but play behaviour mirrored variation in maternal investment. In addition, those individuals that played more survived better and had better body condition as yearlings despite weaning earlier. Since increased activity has been linked to enhanced musculoskeletal development in domestic horses, we suggest that play provides a link between increased maternal investment, increased body condition and future reproductive success in feral horses, and probably in other species.

	Title	Maternal programming of individual differences in defensive responses in the rat			Type	Journal Article
	Year	2004	Publication	Annals of the New York Academy of Sciences	Abbreviated Journal	Ann N Y Acad Sci
	Volume	1032	Issue		Pages	85-103
	Keywords	Adaptation, Biological; Aggression/physiology; Animals; Evolution; Female; Gene Expression/physiology; Humans; Individuality; Maternal Behavior; Phenotype; Pregnancy; Prenatal Exposure Delayed Effects; Rats; Stress, Psychological/physiopathology
	Abstract	This paper describes the results of a series of studies showing that variations in mother-pup interactions program the development of individual differences in behavioral and endocrine stress responses in the rat. These effects are associated with altered expression of genes in brain regions, such as the amygdala, hippocampus, and hypothalamus, that regulate the expression of stress responses. Studies from evolutionary biology suggest that such “maternal effects” are common and often associated with variations in the quality of the maternal environment. Together these findings suggest an epigenetic process whereby the experience of the mother alters the nature of the parent-offspring interactions and thus the phenotype of the offspring.

	Title	Human-mare relationships and behaviour of foals toward humans			Type	Journal Article
	Year	2005	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	93	Issue	3-4	Pages	341-362
	Keywords	Horse; Human-animal relationship; Maternal influence; Early experience; Social facilitation
	Abstract	We studied experimentally whether horse dams influenced foals' relationships with humans. We investigated the influence of the establishment of positive human-mare relationships on foals' behaviour toward humans. Forty-one foals and their dams were involved in this experiment. Half of the mares were softly brushed and fed by hand during a short period (total of 1.25 h) during the first 5 days of their foals' lives (experimental group, n = 21). The other mares were not handled experimentally and their foals received no contact with the experimenter (control group, n = 20). The reactions of both experimental and control foals were recorded under various conditions, first, for 5 min in the presence of a motionless experimenter, when foals were 15 and 30-35 days old, then in an approach test when they were 15 days old and in a saddle-pad tolerance test when they were 30-35 days old. Finally, approach-stroking tests were performed successively by the familiar experimenter when foals were 11-13 months old and by an unfamiliar person when they were 13-15 months old. Several observations strongly suggest that mares can influence their foals' behaviour toward humans: (1) during the handling procedure, experimental foals of protective mares were further from the handler than foals of calm mares (p < 0.001); (2) experimental foals remained, at all ages, closer to the experimenter (p < 0.05) and initiated more physical contacts (sniffing, licking, etc.) with the experimenter (p < 0.05) than control foals; (3) avoidance and flight responses of experimental foals were considerably reduced during approaches by the experimenter (p < 0.01) and they accepted saddle-pads on their backs more easily (p < 0.01) and more quickly (p < 0.01) than control foals. Lastly, the consequences of handling mares had effects that lasted at least until foals were one year old (p < 0.05) and became generalized from experimenter to unfamiliar humans, who could approach and stroke experimental foals rapidly during a test (p < 0.05). This is the first report of an attempt to use observation of mother by foals to facilitate human-foal relationships. The procedure is simple, takes little time and can easily be applied to any dam-foal pair, as it is not intrusive and presents no risks of disrupting mare-foal bonds.

	Title	Behavioral patterns and proximate reason of young male separation in Misaki feral horses			Type	Journal Article
	Year	1997	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	54	Issue	4	Pages	281-289
	Keywords	Misaki feral horse; Horse maternal-filial bond; Social behavior; Separation season; Separation reason
	Abstract	The present investigation was undertaken to study the proximate reasons why and the behavioral patterns of young male Misaki feral horses when they left their natal band or mothers. We observed a total of ten young males twice a month from January 1988 to December 1995. Almost all young males left their natal band or mothers at between 1 and 4 years of age. We found that, during the separation process, all the young males from first parity dams returned several times after the initial separation, indicating a strong attachment between primiparous mares and their male offspring. The other five separated only once without rejoining. Our observations showed five variable behavior patterns of young males at separation time, depending on the consort relation between their mothers and harem stallion and the reason for separation at that time. Eight young males separated in the non-breeding season at average 2.1 years and the other two separated in the breeding season at average 3 years and the average difference was not significant. These results revealed that 80% of the young males separated voluntarily when the natural resources become poor whereas 20% separated when their siblings were born.

	Title	Sow behaviour involved in the crushing of piglets in outdoor farrowing huts--a brief report			Type	Journal Article
	Year	2003	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	80	Issue	2	Pages	109-115
	Keywords	Pig-maternal behaviour; Crushing; Free-ranging; Welfare
	Abstract	This study focuses on maternal activities involved in the trapping of piglets by the sow's body in outdoor farrowing systems and examine the mother-piglet context leading either to the death of piglets or to their survival. The behaviour of six Large-WhitexLandrace sows and their litters was continuously video recorded at their first and second parity, during the 40 h following parturition. Crushing mainly occurred at evening and night, during the first 12 h of farrowing and involved changes between lying, sitting and standing positions, as well as between udder and side lying. No piglet died from savaging. Nevertheless, aggressive behaviours of sows were observed, particularly in their first maternal experience. The immediate context of trapping was related to the labour of the sow and to the feeding and resting of piglets. The immediate crushing context was related to active avoidance of restless piglets while lying down, as well as sitting and standing behaviours. These results are discussed in terms of differential reactions of the sow to suckling attempts of piglets.

	Title	Maternal behavior of Belgian (Equus caballus) mares			Type	Journal Article
	Year	1994	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	41	Issue	3-4	Pages	161-189
	Keywords	Belgian; Draft horse; Ontogeny; Maternal aggression; Maternal behavior; Nursing behavior; Recumbency response
	Abstract	The relationship between ten Belgian mares and their offspring was studied from the first day of foal life to 17 weeks of age. Mares and foals spent more time at greater distances from each other as foals matured. Mares exhibited the recumbency response, being in closer proximity to their foals when foals were recumbent than when they were upright. Foals initiated the majority of nursing bouts. Frequency and duration of nursing bouts and percentage of time resting recumbently declined as foals matured. Foals also terminated the their foals, and they were most likely to do so in the first month of foal life. Maternal initiation of nursing. There was usually no discernible foal response to maternal aggression. Little difference between maternal behavior directed towards colts and fillies was found for all aspects of the study. Maternal behavior in the Belgian draft horse was similar to that reported for other equid breeds.

	Title	Formation and dissolution of the mare-foal bond			Type	Journal Article
	Year	2002	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	78	Issue	2-4	Pages	319-328
	Keywords	Maternal; Horse; Foal; Separation; Ontogeny
	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.
