To investigate the protein sparring effect of ㎗-methionine and ℓ-lysine on the egg type pullet ration, this experiment with a total of 288 Hisex strain pullets was carried out for a period of 8 weeks (15-22 weeks), 8 treatments of (1) control, CP l4%, (2) basal, CP 12%, (3) basal + lysine 0.1 %, (4) basal + lysine 0.2 %, (5) basal + methio;nine 0.1 %g (6) basal + methionine 0.2%, (7) basal + lysine 0.1 % + methionine 0.1 %, (8) basal + lysine 0.2% + methionine 0.2% with 3 replicates were employed in this experiment. Metabolism trial was conducted at the end of feeding trial. The obtained results were summarized as follows; 1. Body gain was higher in the basal treatment than in other treatments. However, there were no significant differences on body weight gain among treatments. 2. Birds fed the basal ration consumed less feed than birds fed the control ration and lysine and methionine supplemented ration. However, no significant differences were found on diet intake among treatments. Feed efficiency was more improved in the lysine + methionine 0.2% treatment than in other treatments. However, there were no significant differences on feed efficiency among treatments. 3. In the nutrients utilization, utilization of dry matter and crude protein was higher in the lysine 0.1 % + methionine 0.1 % and lysine 0.2% + methionine 0.2% treatments than in other treatments. 4. In the economical analysis, feed cost required for ㎏ body gain was lowest in the basal treatment and next in the lysine 0.2% and lysine 0.2% + methionine 0.2% treatments. Therefore, based on the results of this experiment, it is concluded that basal treatment (CP 12%) was most profitable among treatments during the period of pullet (I 5-22 weeks) and next in order of lysine 0.2%, lysine 0.2% + methionine 0.2% and lysine 0.1% + methionine 0.1 % treatments, respectively.
