The design, manufacture and insertion of a cannula into the stomach of first-litter gilts to facilitate superalimentation during lactation is described. Anaesthesia, surgery, and the presence of cannulas had no detrimental effects on birth parameters or on the gilts' ability to lactate and suckle their young. Stomach cannulation enabled us to infuse 37% more food into gilts during a 28-d lactation, and is an excellent research tool for manipulating nutrition during lactation. Key words: Gilts, lactation, surgery, stomach cannulation, superalimentation
