LIMESTONE OF BUKIT KAMANG AS A CALCIUM SOURCE FOR LAYING HENS [PDF]
, 2009 A feeding trial was conducted to study the use of natural limestone meal originated from Bukit Kamang located at Agam district of West Sumatra to substitute fresh water oyster shell as the main source of calcium in diet of laying hens. The mineral feed

Extracellular Matrix Molecules of the Eggshell as Related to Eggshell Quality [PDF]
, 1997 The extracellular matrix of the mineralizing eggshell contains molecules hypothesized to be regulators biomineralization. To study eggshell matrix molecules, a bank of monoclonal antibodies was generated that bound demineralized eggshell matrix or localized to oviduct epithelium.

Errors in Measuring and Calculating Eggshell Quality
Poultry Science, 1994 Abstract Three experiments were conducted to examine potential errors in measuring or calculating eggshell quality. In Experiment 1, specific gravity of eggs was measured in increments of .001 and .0025, and the increments of .0025 were combined for increments of .005.

International Journal of Poultry Science, 2008 In this experiment, two trials were conducted to determine whether broiler breeder eggshell color could be used as an easy means of predicted eggshell quality. In Trial 1, 4320 commercial broiler breeder eggs were obtained. Specific gravity (SG) was measured and color determined on the eggs on the day of lay.
