The protein composition of the insoluble avian eggshell matrix was studied. The determination of these proteins insoluble in water (EDTA-insoluble) was carried out using enzymatic cleavage followed by a high-performance liquid chromatography-mass spectrometry method. The influence of various enzymes on the protein splitting also was studied. The distribution of proteins depends on the type of l...

Determining the age of bird remains after cessation growth is challenging due to absence techniques such as tooth eruption and wear available for mammals. Without these techniques, it difficult reconstruct hunting strategies, husbandry regimes, wider human–animal relationships. This paper presents a new method, developed from collection (n = 71) known-age specimens domestic fowl (Gallus gallus ...
