The authors have investigated the effect of different levels guanidinoacetic acid in the diets of quails on their productivity and carcass quality. Experimental studies were carried out in the conditions of the problematic research laboratory of feed additives in the National University of Life and Environmental Sciences of Ukraine. Material for scientific and economic experience was quail of Pharaoh species of meat direction of productivity. The experiment was carried out by method of groups-analogues. Compound feed were fed in dry crumbled form. Young animals were fed in a group. The daily amount of compound feed was divided in two parts – morning and evening rations. The effect of using different levels of Guanidinoacetic Acid (GAA) in compound feed on productivity and carcass quality of young quails was studied. We have found that compound feed with the level of GАА 0.06% contributes to live body weight increase by 3.9 g and muscles of the pelvic limbs yield by 26.2%. At the same time, use of diets with a level of 0.12% of guanidine acetate increases live weight by 13.5 g, the absolute growth of 6.5 g, average daily growth by 0.9 g, a relative growth of 2%, the mass of carcass, semi-eviscerated carcass, and eviscerated carcass of 4.8, 4.9 and 4.3% correspondingly, slightly increases the mass of pectoral muscles by 9.1%, significantly increases the yield of muscles of the pelvic limbs by 36.4%, and reduces feed conversion by 5%. Poultry which was fed with 0.18% of GАА exceeded control of body weight by 12.2 g, the absolute growth by 4.4 g, average daily growth by 0.6 g, the relative growth by 1.1%, yield of muscles of the pelvic limbs by 36.4% and  had a lower feed conversion rate by 9.1%. During the study period the safety of livestock which was fed with GААvwas high and ranged from 90 to 96%.  It was established the perspective of further research, which is to examine the impact of Guanidinoacetic Acid on the egg production of egg-laying quails, morphological and chemical composition of eggs and  their hatching  quality.
