This study was undertaken to determine the effects of storage period and egg weight of hatching eggs of Japanese quails on fertility, hatchability results. Eggs were obtained 150 females quails, all at 15 weeks of age. A total of 1942 hatching eggs were separated into 3 groups as light-weight (9.50-10.50 g), medium-weight (10.5111.50 g), and heavy-weight (11.51-12.50 g). Based on storage period...

متن کاملRearranging gastrulation in the name of yolk: evolution of gastrulation in yolk-rich amniote eggs
Gastrulating birds and mammals form a primitive streak in lieu of a circular blastopore, and a conspicuous underlying tissue layer, the hypoblast. In an attempt to understand the evolution of these amniote characteristics, pregastrula and gastrulation stages in selected amniotes are compared with the more ancestral situation in amphibians. At blastula/blastoderm stages, the overall fate maps an...
