Some changes in composition and properties of the hen's egg on incubation.

Morphologic Evaluation of the Fertilized and Unfertilized Ostrich Egg during the Early Stages of Development (MRI Analysis)

Introduction: The magnetic resonance imaging (MRI) technique permits to monitor the development of the embryo in vivo without causing any developmental defects. Although increasing application of MRI imaging are predicted in veterinary sciences, there is little information available about MRI studies of avian embryos and their eggs. The objective of the present study was to evaluate the o...

Physics of the Hen's Egg I. Membranes in the Egg

THIS paper is an account of observations made on the composition and behaviour of certain of the membranes in the hen's egg. The composition is based on the examination of stained sections; the results should, however, give pointers in a purely chemical survey. Needham(i) has reviewed the work—chemical and histological—that has been carried out on the nature of the yolk and shell membranes. The...

Carbohydrates in protein. 3 The preparation and some of the properties of a glycopeptide from hen's-egg albumin.

The Effect of Doxycycline on the Viability of the Quail Embryo During Incubation Period

Objective: In recent years, antibiotics have been used widely in the glob to prevent and treat bacterial diseases. They injected into eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major concern. There is little information available about the safety of tetracycline drugs in the embryonated eggs of the birds. The ob...
