| Popis: | Layer hybrids are more superior in the egg yield than pure breeds. But this superiority causes some problems in the bones during the production period. There are a lot of differences among genotypes in the production period that have been examined extensively, however, the differences throughout incubation period aren’t known yet. Thus, the objective of this study was to evaluate the differences in femur properties of pure breed and layer hybrid embryos during the incubation period. A total of 354 fresh hatching eggs were used from one hybrid (Lohman White) and two pure breeds (Denizli & Gerze). The eggs were incubated. Hatching eggs from each genotype at the beginning of embryonic days (E) 19 and E21 were examined. At these embryonic ages, 12 eggs were selected from each genotype. The eggs were opened and embryos were sacrificed by cervical dislocation. Both femurs were dissected from each embryo and then structure, mineral composition and mechanical properties of femur were determined. The genotype affected the length, width and Zn level in the femur of embryos. Weight, length, width, load of yield and ultimate, ash and all examined minerals increased with embryonic development. These results showed that some femur properties of embryos were influenced by the genotype and layer hybrid embryos are beginning to be advantageous in terms of Zn level in the femur at E21. This study leads to better understanding femur development during the incubation period in layer hybrid and pure breeds. |
