Abstract
The present study was carried out at EL-Sabhia Poultry Research Station, Animal Production Research Institute, Agricultural Research Center during 2005 to 2008
Two local strain of chicken Mandarah (Mn) and Silver Montazah (SM) and one commercial strain Lohman Brown (LB) were used in this study
In the first generation a total of 10 males for sire line (SM) and (Mn) and 100 females of (LB) strains were used to produce Mn x LB and SM x LB crosses In the second generation, which the three-way crosses and the reciprocal cross was developed, with matting between males and females of two-way crosses, (LB) contributed 50% of the three-way cross
Three-way crosses improved ASM, BW at different ages, EN and EM during different periods and decreased fertility %, hatchability traits % and BW at sexual maturity than the local strains
These results may be due to cross local strain with commercial strain.
