Title Compensatory social responses of older pigtailed monkeys to maternal separation Type Journal Article
Year 1981 Publication Developmental Psychobiology Abbreviated Journal Dev Psychobiol
Volume 14 Issue 2 Pages 163-168
Keywords (up) Animals; Dependency (Psychology); Female; Macaca nemestrina; Male; *Maternal Deprivation; *Social Behavior
Abstract Thirteen 3-5-year-old pigtailed monkeys were subjected to five 2-hr maternal separations while remaining in their normal social group. Significant changes in activity profiles were noted during separation and reunion phases. This suggests the continued social dependence of older offspring upon the matriarch. The shift in social activities reflected attempts by the juvenile and adolescent subjects to compensate for maternal absence by intensification of other affiliative social behavior and avoidance of potentially socially disruptive situation. The subjects oriented more towards kin in the absence of the matriarch, but actual time with kin decreased. Upon the return of the matriarch, the intensified some responses depressed during her absence and returned to preseparation social relationships. Play and aggressive responses declined whereas social approaches increased during maternal absences. Submissive responses declined upon the return of the matriarch, and play increased. The subjects also showed a marked, temporary increase of direct interaction, largely sniffing and grooming, with the matriarch upon her return.

Title Macaque social culture: development and perpetuation of affiliative networks Type Journal Article
Year 1996 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 110 Issue 2 Pages 147-154
Keywords (up) Animals; Dominance-Subordination; Female; Macaca mulatta/*psychology; Male; Maternal Behavior; *Peer Group; Sexual Behavior, Animal; *Social Behavior; Social Distance; *Social Environment
Abstract Maternal affiliative relations may be transmitted to offspring, similar to the way in which maternal rank determines offspring rank. The development of 23 captive female rhesus monkeys (Macaca mulatta) was followed from the day of birth until adulthood. A multivariate analysis compared relations among age peers with affiliative relations, kinship, and rank distance among mothers. Maternal relations were an excellent predictor of affiliative relations among daughters, explaining up to 64% of the variance. Much of this predictability was due to the effect of kinship. However, after this variable had been controlled, significant predictability persisted. For relations of female subjects with male peers, on the other hand, maternal relations had no significant predictive value beyond the effect of kinship. One possible explanation of these results is that young rhesus females copy maternal social preferences through a process of cultural learning.

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 (up) 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 Mummy’s Boys: Sex Differential Maternal Offspring Relationships in Semi-feral Horses Type Conference Article
Year 2012 Publication Proceedings of the 2. International Equine Science Meeting Abbreviated Journal Proc. 2. Int. Equine. Sci. Mtg
Volume in press Issue Pages
Keywords (up) dispersal, Equus ferus caballus, social, maternal investment
Abstract In polygynous species with high reproductive skew in males, mothers often show differential investment between sons and daughters; however consistent sex differential investment has not been found by previous studies in horses. We investigated sex differences in mother-offspring relationships in nutritionally independent sub-adult semi-feral Carneddau Welsh mountain ponies Equus ferus caballus. Mothers and their sub-adult sons had consistently closer relationships than mothers and daughters. Stronger affiliative bonds between mothers and sons were quantified by their maintenance of closer proximity, higher rates of affiliative interactions and more frequent suckling bouts. These measures of affiliation were temporally associated with higher aggression levels directed towards sub-adults by other band members, particularly stallions. We suggest that aggression may serve as the proximate mechanism driving male dispersal in feral horses and that the stronger mother-son bond signals an attempt to delay their dispersal, highlighting conflict within the band concerning dispersal timing. Since males become increasingly central within the band over time, with mature stallions requiring excellent social skills in order to both acquire and keep a band of mares, we propose that delaying colts' dispersal allows for further development of these skills in a relatively safe environment. This additional investment is expected to maximise their reproductive success. This study illustrates how social network theory can be used to quantify individuals' social experiences, contributing to a greater understanding of the evolution of group living. It also gives us further insight into the mechanisms underlying dispersal in wild and semi-wild horse populations and how conflict often arises when individual needs differ.

Title Accompanying pre-weaned Thoroughbred (Equus caballus) foals while separated from the mare during covering reduces behavioural signs of distress exhibited Type Journal Article
Year 2004 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 88 Issue 1-2 Pages 137-147
Keywords (up) Distress; Foals; Maternal separation; Stereotypies; Welfare
Abstract Some Thoroughbred stallion farms separate the mare from the foal during breeding, leaving the foal alone in its stall. Such separation often leads to distress in the foal, as evidenced by behavioural indicators such as vocalisations, pacing or moving about, pawing and striking the body against solid objects. This study examined whether the foal's distress is reduced if a handler accompanies it during the period of separation. A total of 57 foals on an Irish stud farm were observed: 27 foals were accompanied during separation and 30 were left in isolation but discretely observed from outside the stall. On average, unaccompanied foals vocalised at significantly (P<0.001) shorter intervals (14.8 s versus 26.8 s), and spent significantly (P<0.05) more time pawing (29.6 s versus 6.8 s) than accompanied ones. In addition, 17 of the unaccompanied foals hurled themselves against a solid object on at least one occasion, while not one of the accompanied foals did this (P<0.001). Age, gender and number of times the foal had been previously separated from the mare while she was being teased or covered were not significantly related to any of the behavioural indicators of distress. Overall, the data provide clear evidence that accompanying a foal reduces the distress that it exhibits when separated from the mare. This procedure has obvious welfare benefits in the short term, in that the foal both experiences less distress and has a reduced likelihood of injuring itself, and it may have longer-term benefits by reducing the chance of the animal later developing a locomotory stereotypical behaviour.

Title Mother-infant bonding and the evolution of mammalian social relationships Type Journal Article
Year 2006 Publication Philosophical Transactions of the Royal Society B: Biological Sciences Abbreviated Journal Phil. Trans. Biol. Sci.
Volume 361 Issue 1476 Pages 2199-2214
Keywords (up) Endorphin; Maternal behaviour; Olfactory memory; Opioids; Oxytocin; Pair bonding; Prefrontal cortex; Social learning
Abstract A wide variety of maternal, social and sexual bonding strategies have been described across mammalian species, including humans. Many of the neural and hormonal mechanisms that underpin the formation and maintenance of these bonds demonstrate a considerable degree of evolutionary conservation across a representative range of these species. However, there is also a considerable degree of diversity in both the way these mechanisms are activated and in the behavioural responses that result. In the majority of small-brained mammals (including rodents), the formation of a maternal or partner preference bond requires individual recognition by olfactory cues, activation of neural mechanisms concerned with social reward by these cues and gender-specific hormonal priming for behavioural output. With the evolutionary increase of neocortex seen in monkeys and apes, there has been a corresponding increase in the complexity of social relationships and bonding strategies together with a significant redundancy in hormonal priming for motivated behaviour. Olfactory recognition and olfactory inputs to areas of the brain concerned with social reward are downregulated and recognition is based on integration of multimodal sensory cues requiring an expanded neocortex, particularly the association cortex. This emancipation from olfactory and hormonal determinants of bonding has been succeeded by the increased importance of social learning that is necessitated by living in a complex social world and, especially in humans, a world that is dominated by cultural inheritance. © 2006 The Royal Society.

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 (up) 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 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 (up) 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 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 (up) 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.
