ABSTRACT 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 &amp; 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...

ABSTRACT Pure breeds are important due to the fact that they adapt well to poor husbandry conditions. However, gene expression of digestive enzymes and nutrient transporters of pure breeds and layer hybrids have not been studied yet. Therefore, this study was directed to detect the gene expression of digestive enzymes and nutrient transporters in the yolk sac membrane and small intestine of the embryos in layer hybrid and pure breeds. A total of 354 hatching eggs were collected from 29 wk old Denizli, Gerze and Lohman White (LW) breeder flocks. Twelve eggs from each genotype were selected at embryonic day 19 (E19) and day 21 (E21). APN, SI, PepT1, EAAT3, CAT1, B0AT, SGLT1 and GLUT5 mRNA expressions were evaluated in the yolk sac membrane (YSM) and small...
