[Chemical composition of poultry livers]

Investigations were carried out on the basic and mineral composition of the liver of slaughtered birds. It was found that the water content of the liver depended on the age and sex, with broilers it being 73.09 g%, with laying hens--72.56 g%, and with cocks--70.62 g%. Proteins had highest percent in the liver of cocks, followed by those in the liver of hens, geese, broilers, and turkeys. The content of fats was highest in the liver of turkey, and in a descending order followed geese, broilers, hens, and cocks. Mineral salts varied from 1.20 to 1.35 g%; highest amounts of sodium were found in the liver of broilers, while highest levels of potassium, calcium, phosphorus, iron, zinc, and copper were established in the liver of turkeys.
