SUMMARY

Resulis of comparative analysis of production Iraits of two light line hen strains, Hisex Brown and Shawcr 579, were presented in this paper. The experiment involved 2520 Shawer 579 and 1150 Hisex Brown hybrid pullets. The Hisex Brown hybrid hens obtained higher laying performance per average hen (87.82 %) and housed hen (85.53 %) in comparison to the Shawer 579 ones (83.24 % ; 81.03%, respectively). Higher egg production per average hen (270.48) and housed hen (263.42) was registered with the Hisex Brown hens as opposed to the Shawer 579 ones (256.49 and 249.58 eggs per average hen and housed hen, respectively). Average daily feed consumption per average and housed hen was lower in the Shawer 579 hybrid. Feed consumption per laid egg was equal in both strains (150.0 g). Mortality was higher in the Shawer 579 strain (5.56 %) as compared to Hisex Brown (5.40%). Based upon the experimental data obtained, it was concluded that the Hisex Brown hens had obtained better production results in the existing production conditions.
