Abstract

In a study involving 12 diet combinations with 3 energy levels (2.6-3.0 Mcal/kg ME), 4 protein levels (14%-20%) 12 calorie-protein ratios (13.13-19.68 Kcal/gm protein) layer chickens performed better on a 3.0 Mcal — 18.45% protein diet (E3.oP18.45) than any other diet, in egg number, egg weight, feed efficiency, protein efficiency ratio, revenue-cost ratio and egg number-feed cost ratio. Average daily feed consumption was 90g. Diets coresponding to N.R.C. levels of E2.85 P15 supported less than 280 Kcal ME or 16.55 g protein daily intake, respectively, and were inferior to the E3.0P18.45 diet.
