摘要

Methods are provided here to increase the concentration of insulin-like growth factor (IGF) in serum of a subject.In one form, the method includes administering IGF-1 active to a subject, in which the concentration of IGF in serum of the subject is increased.Also provided are methods for the treatment of a condition in a subject, methods to improve or maintain the health of a subject and methods to improve a characteristic of a subject.Examples of conditions include a motor neuron disease, Alzheimer's disease, myocardial infarction, ischemic hypoxic brain injury, osteoporosis.Repair of skeletal muscle and failure of growth.Examples of features include increased milk production, increase of fertilization, increased reproduction, growth,To increase the quality of oocytes in a ruminant submitted for superovulation and embryo increased viability.In one form, the IGF-1 administered to the subject is obtained from a natural source which has been processed to increase the amount of IGF - 1 active.
