A Comparative Histological Study Of Protein And Calcium Content In Skeletal Muscles Of Green-Winged Teal And Domestic Duck

Abstract

The meat of poultry has been a source of beneficial protein and minerals. Thus, the aim of the current study was to identify the composition of protein and calcium in Green-Winged Teal and domestic ducks' skeletal muscles. Ten adult male green-winged teals and 10 adult male domestic ducks bought from commercial markets in Kut City were utilized for the study. The samples were taken from the chest and leg areas of Green-Winged Teal and domestic ducks. The samples were then prepared into histological sections, where two stains were applied: bromophenol blue to quantify total protein content and alizarin red to quantify the content of calcium. The study found that Green-Winged Teal skeletal muscles contained more protein and higher calcium deposition than domestic duck muscles. The difference in the composition of skeletal muscle between the samples is due to the difference in species, diet,and physical activity levels.
