Abstract: An experiment was conducted to evaluate the effect of Methioine, Lysine and Cystine (amino-cystine acids) supplementation on the feed consumption, Egg Production, Fertility, Hatchability, mortality and weight of day old chicks of Laying Japanese Quails at Poultry Experimental Station, Sindh Agriculture University, Tandojam. For this purpose 100 hundred laying quails having 14 week of age were purchased and reared. The quails were divided in four equal groups A, B, C and D and were fed on commercial rations. Three Amino acids (Methionine, Lysine and Cystine) as a supplement was mixed in feed. 0.3, 0.9 and 0.5 gm/kg feed in group A, 0.5, 1.2, 0.7 gm/kg feed in group B and 0.9, 1.6 and 1.1gm/kg feed in the groups C respectively. Results revealed highly significant difference among the groups. Greater egg production (96.45%), fertility (76%) and Hatchability (66%) was observed in groups B, while least in-group D lowest feed consumption was observed in group B. While least in-group D. lowest feed consumption was observed in gorup B. No any mortiality was recorded in any group. It was concluded that laying quails can be reared on ratio containing 0.5, 1.2 and 0.7gm/kg feed level of Methionine, Lysine and Cystine in quails ration for better production performance.
