Abstract
The turkey females were randomly distributed on four groups, each group consisted of 12 birds depend on strain. The strains as follow, (T1): red turkey strain, (T2): bronze turkey strain, (T3): white turkey strain, (T4): black turkey strain. Each group constituted from 3 replicates and each replicate has 4 females. All birds housed under same environmental conditions. Feed and water were available (ad libitum) for all the period. Birds were fed on diet contains 20% crude protein and 2950 Kcal metabolic energy / kg through the experimental period. The flock was reared in a ground cages (pens) during the experiment period. Eggs were collected twice daily. Black turkey strain achieved the highest results, whereas the red strain recorded the lowest results in all traits measured in this study, also white turkey strain had superior on bronze turkey strain in all traits. Results revealed that strain had Significant effected on egg production rate, cumulative eggs number, egg weight, egg mass and feed conversion ratio, but, there was no significant effected for strain on feed intake.
