We utilized a total of 360 one-day-old male Ross308 chicks. We allocated the chicks to four different dietary treatments, each consisting of six duplicates. Each replica consisted of 15 chicks per pen. The study included four dietary treatments: Control (CON), CON diet supplemented with 0.125% AY, CON diet supplemented with 0.25% AY, and CON diet supplemented with 0.50% AY. These treatments were administered using a corn-soybean meal-based basal diet served as the basis for administering these treatments. The data on different parameters was analyzed using the analysis of variance technique with a completely randomized design. The treatment means were compared using Duncan's multiple range test. The research showed that between days 25 and 36, chicks that were given AY at concentrations of 0.125, 0.25, and 0.50% had lower feed intake and a better feed conversion ratio (p}, journal = {American Journal of Animal and Veterinary Sciences}, publisher = {Science Publications} }
