ABSTRACT
An experiment was conducted to evaluate the carcass yields of male and female Arian broilers fed with three different lysine levels viz. high lysine (110% NRC), standard (NRC) and low lysine (90% NRC). This experiment was conducted using 600 male and female broiler chickens in 6 treatments with 5 replicates (20 broilers) in the completely block randomized design. Increasing lysine level (110% NRC) in diet significantly increased growth characteristics in male and female broilers. Results obtained in our study suggested that diets based on DAA and 110% NRC lysine requirement level significantly increased carcass yields in both sex. Broiler can respond to higher levels of dietary lysine than has been reported in the NRC.
