During recent years a growing interest has been manifested by feeders of stock in the form of cooked maize known as flaked maize, which is produced on the industrial scale by the steaming and rolling of maize grain. Following the publication of the results of an investigation into the comparative values of dry, soaked, cooked and flaked maize for pig-feeding, in which investigation the high digestibility and feeding, value of flaked maize were amply demonstrated, frequent enquiries have been received as to whether it is justifiable to assume an equal feeding value for the several brands of flaked maize which are put on the market at the present time.
