Egg shellThin Layer ChromatographyRhipicephalus sanguineusTicksAcid hydrolysis of the protein fraction of a batch of egg shells of Rhipicephalus sanguineus was followed by determination of the amino acids in the hydrolysate. Using thin layer chromatography, the amino acids—lysine, arginine, aspartic acid...

The results showed that, compared to the FL regimen, the LED regimen resulted in higher egg weight, albumen height, and albumen weight at 27 wk of age, thicker shells at 40 wk of age, but lower egg weight at 60 wk of age. Egg quality change was similar between the lighting regimens ...
a method for obtaining the composition that comprises placing raw poultry eggs with their shells in a tank containing diluted acetic acid and sodium chloride for one month so that the composition contains the solubilised forms of the compounds naturally occurring in the shell of a poultry egg. ...
