Abstract

This study was carded out in Rids poultry Research Station, Ani-mal and Poultry Production Research Institute. Agricultural Research Cen‌tre, to evaluate the performance of second generation of three gene. types chickens. cross,(produced from dam Dandarawi x sire shaver) and its reciprocal from sire Oandarawi x dam shaver and Dandarawi from dam Dandarawi and sire Dandarawi, when producing first generation chicks (Abdel-Galel 1999). During production second generation chicks, males from each genotype were mating with females of the same genotype. The data obtained can be summarized from the study as follows: 1-cross hens had heavier body weight than both their reciprocal (at hatch and 40 weeks old) or Dandarawi hens (at hatch. 20 and 40 weeks old), also reciprocal cross had heavier weight than Dandarawi hens. 2- cross hens laid first egg and reached 50% production later than both their reciprocal or Oandarawi hens, the reciprocal hens reached to age of first egg and 50% production later than Dandarawi hens. 3-Dandarawi chickens were more viable than cross Or their recip‌rocal thickens during growing period, but there were no significant differ‌ences during laying period in respect to viability of different genotypes. 4- cross hens had heavier egg weight, more egg number during first 150 days. more egg mass than both their reciprocal cross or Dan-darwei hens, also reciprocal hens had significant superiority In this traits than Dandarawi hens. 5-Although,cross hens consumed more feeds during laying period than their reciprocal or Dandarawi hens, but, they were more efficient In conversion of feeds to eggs than their reciprocal ot 0111KIS/Vei hens. Moreover, the reciprocal cross hens were more efficient in conversion of feed to eggs than Dandarawei hens. 6-Dandarawei hens had higher fertility and hatchability percentag‌es than both aces and reciprocal cross, but, there were no significant differences between cross and its reciprocal in this traits. Moreover, fer‌tility and hatchability were higher in winter than summer and there were significant interaction between genotype and season in this tran.
