[An animal model of pump-controlled gastroenteric feeding]

A model for the study of gastroenteric feedings was established in guinea pigs. The model consists of guinea pig with gastrostomy tube and pump-controlled continuous enteral infusion system, with a swivel between the gastrostomy tube and pump system, so that the guinea-pig could move freely in the cage during the experimental period. We used this model for continuous gastroenteric feeding study lasting 2 weeks, and the mortality of animal was low. It is simple, easy to operate, inexpensive and suitable for the experiment of gastroenteric feeding.
