The Changes in Egg Shell Strength During Incubation

Relationship Between Shell and Shell Membrane Strength and Other Egg Shell Characteristics

There was a significant difference in the shell strength of chicken eggs with different curvatures of the large end. Holding temperatures of eggs significantly influenced shell strength but not shell membrane strength. There was a significant negative correlation in chicken eggs between shell strength and membrane strength in small and medium curvature groups but not in the large curvature grou...

Alizarin marking of whitefish, Coregonus lavaretus otoliths during egg incubation

Alizarin red S from 200 to 5000 mg L was used to mark the otoliths of whitefish embryos Coregonus lavaretus (L.) from 5 days after fertilization until shortly before hatching, to develop a method for evaluating the effect of stocking whitefish. Mark quality depended on developmental stage at the time of immersion. The best results were obtained when the otolith primordia had formed and had star...

Estimation of Lime in the Shell and in the Interior of the Egg, before and after Incubation.

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

The effects of incubation on fertile and infertile eggs were examined. The examination included chemical, bacteriological, physical and organoleptic tests for changes which had taken place. Isovaleric acid was identified in all incubated eggs and also in certain fresh eggs. Additional unidentified compounds were detected in the incubated samples. Upon storage at 1 “C, it was observed that the l...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
