## Abstract
The body naturally produces guanidinoacetic acid (GAA), an organic acid that serves as a precursor to creatine, an energy carrier in cells.An experiment was conducted to determine the response of native chickens to GAA.The GAA used is CreAMINO, added to the feed during rearing up to 70 days of age.The native chicken was allotted to 4 treatments, each with 5 replicates of 6 chickens/pen.Four commercial diets were as control (without added GAA and Betaine): 0.06% GAA + 0.1% Betaine, 0.12% GAA + 0.1% Betaine, and 0.18% GAA + 0.1% Betaine.As a result, GAA provides additional energy for optimal growth.The criteria of responses were feed intake, feed efficiency, body weight gains, carcass weight, innards weight and length, intestinal morphology, histology on muscle, and meat quality.Supplementation of native chicken diets with 0.06 GAA resulted in the highest live weight gain, chicken wings, and chicken thighs.In 0.12 GAA, they resulted in the highest average daily gain, lowest feed conversion ratio, carcass weight, breast thighs, chicken back, and chicken lower leg.In 0.18 GAA, the lowest feed intake, feed efficiency, and meat cholesterol were found.Different GAA levels tend to give different results on native chicken performances.
