Adequate Calcium Nutrition and Quality of Egg Shell and Bones in Layers – Innovative Approach

Calcium metabolism (Ca) in layers depends on many factors which can be divided into factors influencing the intake, absorption, retention and/or excretion of Ca. Varying of any of above mentioned factors presented and reviewed in this study, exhibit their impact on quality of bones in layers and egg shell quality. For the purpose of maintaining of the egg quality and quality of layer hens’ bone...

Calcium in sea urchin egg during fertilization.

Calcium plays a strikingly important role in two of the major events in developmental biology: cell activation and differentiation. In this review we begin with the location and quantity of intracellular calcium in sea urchin oocytes, and then discuss the changes that occur during fertilization and egg activation, placing special emphasis on the mobilization and redistribution of intracellular ...
