“…Two main types of behavioral changes were observed in groups of young after introduction of adults: in behavioral patterns and in social relationships. One major feature of the behavioral changes was the enlargement of their behavioral repertoires; a greater diversity of behavioral patterns was expressed in all experimental groups: lying recumbent -indicating quiet state (McCann et al, 1988)-, adult-like patterns such as sexual behavior or encounter patterns and juvenile behavior displayed toward adults (such as snapping) were observed. None of these activities had been observed before the adults were introduced.…”

We investigated the effects of the introduction of foreign adults on the behavior of young horses. First, we observed the behavior of 1- and 2-year-old domestic horses housed in same-age and same-sex groups (a standard housing system, but different from a natural situation). Then, two same-sex adults were introduced into each experimental group. Observations made before, during and after an introduction indicated that young horses reared in homogeneous groups of young had different behaviors compared to other domestic horses reared under more socially natural conditions. After the introduction of adults, young horses expressed new behaviors, preferential social associations emerged, positive social behavior increased and agonistic interactions decreased. These results have important implications both for understanding the influence that adults may have on the behavior of young horses, and in terms of husbandry, indicating the importance of keeping young horses with adults, although further studies are still necessary.

“…Temperament assessments have mostly focused on behavioural observations in test situations under standardised conditions via ethograms or even just via handler questionnaires (Buckley et al, 2011;Grajfoner et al, 2010;Momozawa et al, 2005;McCann et al, 1988). Recently research has increasingly recognised the important influence of environmental factors, such as housing, diet, weaning or training methods and horse-human interaction on the behaviour and temperament of horses (Young et al, 2012;Visser et al, 2008;Hausberger et al, 2008;Nicol et al, 2005).…”

“…Nervous horses exhibit specific behavioural patterns and higher overall activity index levels, and are typically less trainable than more docile horses (Heird et al 1981;McCann et al 1988). More highly reactive horses may also pose greater risks to humans involved in equestrian activities.…”

Highly reactive horses may pose risks to humans involved in equestrian activities. Among the factors that may affect horses' reactivity to external stimuli are pesticides used for fly control in equine facilities. The organophosphorus (OP) insecticide tetrachlorvinphos (TCVP) is used as a feed-through larvicide to prevent completion of the fly larval life cycle in horse manure. TCVP exerts its effect by inhibiting the enzyme cholinesterase (ChE) leading to the accumulation of the neurotransmitter acetylcholine (AChE) in synapses of the central and peripheral nervous systems. The aim of the present study was to investigate alterations of whole-blood ChE levels associated with feeding a commercially available product (Equitrol, Farnam Companies, Inc.) to horses for fly control. A second aim was to report neurological, physiological and behavioural findings in addition to profiles of selected immune markers (IFN-gamma, IL-12p40 and COX-2) and serum thyroid hormones during and after a 30-day treatment period of TCVP feeding. The results indicated significant decreases in whole-blood ChE activity and concomitant behavioural alterations, manifested as increased reactivity and decreased controllability in treated horses. No changes were detected in physiological or neurological parameters, immune markers or thyroid hormones in treated (n=6) or control (n=4) horses during the course of the study.
