The optimum levels of.Lysine and Glutamine needed f.r growth perf.rmance and maintenance of.the chicken broilers were evaluated in a randomized 3 × 4 f.ctorial arrangement of.dietary treatments. The battery cages measured 99 × 66 × 25 cm that can be suf.icient f.r 5 birds. Day old Chicken broilers totaling 180 were assigned to dietary treatments comprising of.3 concentrations of.Lysine (0.85, 1.14, and 1.42) each in combination with 4 concentrations of.Glutamine (0, 1, 2, and 3). Each dietary treatment was replicated 3 times and each replication had 5 birds. The birds were given f.ed and water ad libitum with a 23-hour light regimen f.r a period of.4 weeks. Then, the experimental birds were evaluated f.r body weight gain, f.ed consumption, and f.ed conversion in order to determine their optimum requirement f.r dietary Lysine and Glutamine. Based on the f.ndings of.this study, the highest perf.rmance was observed in birds f.d the diet supplemented with 1.42 lysine and 1% glutamine, but the highest improvement in f.ed conversion was observed in diet contain 1.14 and 1.42 with 1% and 3% glutamine, respectively. Birds f.d 1.42 lysine and 1% glutamine had the highest total body weight gain and f.ed consumption. The lysine requirements in the diet f.r Chicken are between 1.14 and 1.42 with glutamine level of.1%.
