The effect of decreasing dietary CP and supplementation of lysine and methionine+cystine on the performance of 270 laying hens Lohmann LSL strain was evaluated in this trial. The birds averaging 26 weeks of age were allotted to a stocking rate of 562 cm2/bird as a completely randomized design with five replicate of six birds. The treatments were as follows: T1 = control diet (CD) with 16.5% CP, 0.80% of lysine (L) and 0.70% of methionine+cystine (MC); T2 = 15.25% CP, […]
