The study was undertaken to determine the effects of lactulose syrup on the growth in young rats at the high-protein (35% casein) level diet. Male Wistar strain rats weight 83g (at 5 weeks of age) fed control diets of 35% casein containing no lactulose syrup, control diets of 18% casein no lactulose syrup, or experimental diets (35% casein) containing 9.5%, 19%, or 28.5% lactulose syrup for 38 days. The following results were obtained : 1) Facal state for 34 days was soft in the 19% lactulose syrup group. Facal state for 38 days was soft in the 28.5% lactulose syrup group. 2) The body weight at 38 days in three experimental groups were low. Body weight in three experimental groups and the 18% casein control group were much the same. 3) The feed efficiency ratio and protein efficiency ratio in three experimental groups were decreased from 35 days. 4) The weight of retroperitoneal fat pads in three experimental groups were low. 5) In the fatty adid composition of retroperitoneal fat pads, palmitic acid was low and linoleic adid was high. The fatty adid composition in three experimental groups and the 18% casein control group were much the same. 6) Lipids (%) of liver in 9.5% and 19% lactulose syrup groups were low. 7) In the contents of cecum, total weight, total thiamin and total riboflavin were increased in three experimental groups.
