A method is described for stimulating the appetite of sucking pigs and for guaranteeing that the sucking pigs are provided with sufficient liquid, by offering the animals an approximately isotonic aqueous solution ad libitum starting when the sucking pigs are one day old up to week six. This aqueous solution has a pH of 2.0 to 4.0 and contains an iron/glutamic acid compound at a concentration of not more than 2% Fe. The solution is palatable to the animals, and their stimulated appetite results in a considerably better weight gain in comparison with sucking pigs who have not been given this solution ad libitum. Moreover, a dilutable aqueous iron salt solution is described for carrying out the appetite-stimulating method, which contains ferric glutamate at a concentration of 20 mg of divalent iron per ml and has a pH of 2 to 2.5. |
