The lower grades of tankage are sometimes adulterated with hair or peat. Meat scrap.—Meat scrap, used for poultry feeding, consists chiefly of meat trimmings which have been cooked to extract as much of the' fat as possible and then ground to varying degrees of fineness.

Pork cracklings contain over 30 per ct. fat and about 7 per ct. less protein than the best grades of tankage. They are fully as valuable as tankage for swine.
