The Mineral Concentration Change of Turkey Eggshell Membranes During Incubation ,

Abstract

Membranes from fertile and infertile turkey eggs were examined during incubation to determine the content of Ca, Mg, Na, and K. The Ca concentration in shell membranes of fertile eggs increased (K.05) as compared with that in infertile eggs, but concentrations of Mg, Na, and K in shell membranes of fertile eggs declined (P£.05) as compared with those in infertile eggshell membranes. The data suggest a possible role for some minerals in regulating functional eggshell properties. (
