| 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... |
