Various Factors Affecting Plasma Free Amino Acid Concentrations in the Horse

A series of trials was conducted to determine the effects of various factors including meal schedule, fasting, age and sex of the animal, protein level and quality, exercise, training, length of time on the diet and sample location, on the resulting plasma free amino acid (PFAA) concentrations in the horse. Six horses were individually fed a complete pelleted diet of 15.1% C.P. at a rate of 1.75% of body weight in either one, two or six meals daily. Horses receiving six meals had more constant level of PFAA than horses fed one or two meals. Feeding one or two meals per day produced large PFAA peaks at five and three h after beginning the meal, respectively. Following the absorptive peak at five h, PFAA declined to a constant level at 20-30 h, then rose to near absorptive levels when the fat was continued for 48 h. There was no plateau of PFAA, indicating that a steady state fasting level was not attained.
