Abstract: Horses are a precocious species that must accomplish several milestones that are critical to survival in the immediate post-birth period for their survival. One essential milestone is the successful transition from the intrauterine unconsciousness to an extrauterine state of consciousness or awareness. This transition involves a complex withdrawal of consciousness inhibitors and an increase in neuroactivating factors that support awareness. This process involves neuroactive hormones as well as inputs related to factors such as cold, visual, olfactory, and auditory stimuli. One factor not previously considered in this birth transition is a yet unreported direct neural reflex response to labor-induced physical compression of the fetus in the birth canal (squeezing). Neonatal maladjustment syndrome (NMS) is a disorder of the newborn foal characterized by altered behavior, low affinity for the mare, poor awareness of the environment, failure to bond to the mother, abnormal sucking, and other neurologically-based abnormalities. This syndrome has been associated with altered events during birth, and was believed to be caused exclusively by hypoxia and ischemia. However, recent findings revealed an association of the NMS syndrome with the persistence of high concentrations of in utero neuromodulating hormones (neurosteroids) in the postnatal period. Anecdotal evidence demonstrated that a novel physical compression (squeeze) method that applies 20 min of sustained pressure to the thorax of some neonatal foals with this syndrome might rapidly hasten recovery. This survey provides information about outcomes and time frames to recovery comparing neonatal foals that were given this squeeze treatment to foals treated with routine medical therapy alone. Results revealed that the squeeze procedure, when applied for 20 min, resulted in a faster full recovery of some foals diagnosed with NMS. The adjunctive use of a non-invasive squeeze method may improve animal welfare by hastening recovery and foal-mare interactions that minimize health problems. This would also avoid or reduce costs arising from hospitalization associated with veterinary and nursing care that sometimes leads owners to elect for euthanasia.

This research is about the use of physical compression or “squeeze” procedure in managing Neonatal Maladjustment Syndrome (NMS), a disorder affecting newborn foals. The study reveals that this non-invasive method expedites full recovery, improves animal welfare, and potentially reduces hospitalization costs.
Research Background
The authors begin by explaining the critical milestones a newborn horse must achieve for survival, including the transition from intrauterine unconsciousness to extrauterine consciousness.
This transition process involves neuroactive hormones and several environmental inputs like cold, visual, olfactory, and auditory stimuli.
The research introduced a new consideration in this birth transition process – a direct neural reflex response to labor-induced physical compression of the fetus in the birth canal, commonly referred to as “squeezing.”
Neonatal Maladjustment Syndrome (NMS)
NMS is a disorder in newborn foals characterized by altered behavior, low affinity for the mare, poor awareness of the environment, failure to bond to the mother, and abnormal sucking, among other neurologically-based abnormalities.
Previously, NMS was believed to be caused exclusively by hypoxia and ischemia, which are altered events during birth.
Recent findings have associated NMS with the persistence of high concentrations of in utero neuromodulating hormones (neurosteroids) in the postnatal period.
Physical Compression (Squeeze) Method
Anecdotal evidence showed that applying a novel physical compression or squeeze method (that involves 20 minutes of sustained pressure to the foal’s thorax) could hasten recovery in some neonatal foals suffering from NMS.
The surveyed veterinarians provide information about recovery outcomes and timelines, comparing foals treated with the squeeze method to those treated with traditional medical therapy alone.
Research Findings
Results revealed that the squeeze procedure, if applied for 20 minutes, led to a faster complete recovery in some foals diagnosed with NMS.
The use of this non-invasive squeeze method could improve animal welfare by accelerating recovery and foal-mare interactions, thereby minimizing health issues.
The squeeze method could also reduce costs associated with hospitalization, veterinary care, nursing care, and even the potential decisions by owners for euthanasia due to excessive costs.
