stable groups and positive contacts improve their capacity to adapt, helping to avoid a phenotype that is vulnerable to stress. Items to Take into Account when Confronting Weaning: Horses are social animals Respecting their needs diminishes stress and generates resistant animals Stable groups have less conflict This makes them more efficient and adaptable Affinity among foals exists This priority link is a valid tool when facing any kind of management Weaning implies sudden nutritional change Manouvers anticipating adaptation of the digestive system in processing a greater amount of fiber and water consumption is possible Dam removal (respecting priority link with another equal) This is one of the most efficient forms of management Presence of adults in groups of foals It improves social conditions; contributes towards appeasement and diminishes conflict Phenotype vulnerable to stress It is generated while raising (ontogenetic) and often causes the genetic promise to fail.
