Effect of utilizing herbal methionine instead of industrial methionine in low protein for layers on performance and quality traits of the egg production

الملخص EN

The aim of this study was to determine using Herbal – methionine (H.

M) instead of industrial Methionine (DL-Met) in Low protein diet Layer of the performance and egg quality traits.

160 ISA Brown layer at old 28 Week Were randomly distributed in to ten nutritional Treatments, T1: control diet( 0.17% DL-Met).

The period of the experiment was 60 days.

The average of egg production (H.

D), egg mass, feed conversion significantly (p<0.05) were better for the birds of the T3 and T4 than all other treatments.

No significant difference among treatments birds for some external and internal quality traits of egg, on other hand founded significant differences (p<0.05) for internal and external traits among treatments.

Key words: DL- Met, H.

Met, layer, egg production and Hagh unit.
