They may be constructed by parenchymal tissue – liver, kidney and spleen; of connective tissue – stomach, intestine, and lung as well as muscle tissue – heart and tongue. Because of the wide variety nutritional composition of the by-products is not the same. Domestic products are more nutritious and rich in nutrients, while Foreign not enjoy similar substances.

For example lung is rich in collagen and elastin, the heart has a nutritional value similar to that of meat of first quality, kidneys abound of lipids and nitrogenous substances and the liver is full of complete protein, glycogen, creatine, choline, water and fat-soluble vitamins. Nowadays, however, there is an often overlooked factor – the use of many chemicals in growing animals.
