Maturity of the neonatal foal.

The immature foal frequently represents a significant management challenge to even the most experienced clinician. The clinical course typically involves complications to a range of body systems,including the musculoskeletal, respiratory, and gastrointestinal systems. Before the commencement of treatment, it is important to provide the owner with an estimation of short-term and long-term survival, expected costs, and possible complications. Formulation of an accurate prognosis can be a difficult task but is aided by knowledge not only of normal maturation but of the factors that affect this process.
