Abstract
Seventy five layer hens (lSA - Brown commercial strain) 24 weeks old were used in this experiment. They were randomly distributed on five treatments (15 hens each treatment, 3 replicated in each treatment.) . The treatments were: T, (control) = 100% imported plant protein concentrate, T2 = 75% imported plant protein concentrate + 25% locally plant protein concentrate, T3 = 50% imported plant protein concentrate + 50% locally plant protein concentrate. T4 = 25% imported plant protein concentrate + 75% locally plant protein concentrate and T s = 100% locally plant protein concentrate. Results indicated that no significant difference in live body weight between the different treatments were found during the different eg& production periods. Weight gains were significantly (P<0.05) differ among egg production periods. SIgnificant differences in e~g production among treatments were found in which T3 and T4 showed the highest H. D.Yo among the treatments . Egg production period (32 - 36 wk.) were the highest among the different egg periods. Significant increase in egg weight and egg mass for T2, T3 , T4 and T, as compared with TI( control) during egg production periods. There were significant differences in feed consumption among treatments during egg Production periods, There were significant differences in feed conversion ratio (g. feed / egg) noticed among treatments. T3 and T4 gave the best feed efficiency during the whole production period. Egg production period (28 - 32 wk.) showed the best feed efficiency 018.2 g. feed / egg) among egg production periods. No significant difference in mortality rate due to the replacement of locally Plant protein concentrate for the imported plant protein concentrate in hens diets. Results of this experiment refer to the possibility of partial substitution (at level of 50 - 75%) of the locally plant protein concentrate instead of the imported plant protein concentrate in layers diets.
