The first days and weeks of a foal's life are the most critical for both immediate survival and long-term welfare outcomes. Understanding neonatal foal physiology and behaviour enables rapid identification of problems and appropriate intervention.
Normal foals stand within 1-2 hours of birth and suckle within 2-3 hours. The first milk (colostrum) provides essential immunoglobulins that are absorbed through the gut only during the first 12-18 hours — after which passive transfer declines. Foals that do not stand or suckle within 3 hours require immediate intervention. Normal foals sleep frequently (up to 8 hours daily in the first weeks, in recumbent positions), are bright and responsive when awake, and show increasing confidence and curiosity within the first days.
Failure of passive transfer (FPT — inadequate immunoglobulin absorption from colostrum) leaves foals profoundly immunocompromised and vulnerable to septicaemia. FPT results from: failure to suckle within the absorption window, poor colostrum quality (mares that run milk before foaling may lose valuable colostrum), or foal illness preventing suckling. Testing IgG levels at 12-24 hours (using commercial test kits or veterinary laboratory) identifies FPT. Treatment with plasma transfusion can provide immunoglobulins after the gut has closed.
Neonatal Maladjustment Syndrome (NMS — 'dummy foal' or 'barker foal') results from perinatal asphyxia causing neurological signs: loss of suckle reflex, failure to recognise the mare, abnormal vocalisation, seizures, and altered consciousness. NMS foals require intensive care (nutritional support, seizure management, protection from self-injury) but can recover with appropriate treatment. The 'Madigan squeeze' technique — briefly compressing the foal in a way that mimics the birth canal — has shown promising results in some cases.
The mare-foal bond is established in the first hours after birth and is critical for foal survival. Mares show strong protective behaviour, and foals learn to identify their dam through olfactory, visual, and vocal cues. Disruption of bonding — through early separation, mare illness, or management interference — can cause rejection and abandonment. Allowing undisturbed bonding time in the first hours, minimising handling during this period, and providing a quiet, secure environment support successful bonding.
Gentle, consistent handling of foals from birth creates positive associations with humans and reduces fear. The imprint training controversy aside, evidence supports that early positive handling (short sessions, not overwhelming the foal) creates more tractable, confident adult horses with better welfare outcomes. Early veterinary examinations, vaccinations, and farriery become less stressful for well-handled foals and for the people caring for them.
Foals transition from exclusive milk nutrition to grazing and concentrate feeding over the first months. Creep feeding (providing concentrates accessible only to foals, not mares) supports growth when mare milk supply is limiting. Weaning at 4-6 months causes acute stress — gradual weaning methods (progressive reduction of mare contact) are less welfare-damaging than abrupt separation. Social housing with other foals after weaning supports behavioural development and reduces post-weaning isolation stress.
