To study the singularity of fore-stomach of ruminants, the utilization of nutrients and energy was compared between ruminal and abomasal feedings using goats fitted with permanent fistulas both at the rumen and at the abomasum as well as a tracheal cannula. The results obtained were as follows: 1) Apparent digestibility of starch was very high in ruminal feeding (98.6%) but low digestibility was observed when the same diet was infused into the abomasum (57.0%). When a diet containing 30% glucose and 45% cornstarch was infused into the abomasum, glucose was completely disappeared from the digestive tract and starch digestibility rose to 73%. From these findings, it is suggested that low digestibility of starch in the post-ruminal alimentary tract of ruminants is not due to the defect of the absorption of glucose produced by starch digestion, but to the defect of starch digestion itself. 2) When a diet containing 75% cornstarch was introduced into the rumen of goats, heat production was 5.1kcal per kg of metabolic body size per hour, and when the same diet was infused into the abomasum, heat production declined to 4.5kcal per kg of metabolic body size per hour. 3) When the diet was given ruminally, heat increment was found to be 30% of metabolizable energy, but when the same diet was given abomasally, it was reduced to 16%. VFA synthesis and its utilization in the rumen can explain the difference of heat increment between ruminal and abomasal feedings of the diet. 4) When the diet containing 75% cornstarch was given into the rumen and abomasum, blood glucose level was not changed after feeding, whereas, when the diet containing 30% glucose was infused into the abomasum, blood glucose level increased after feeding. From this result, it is suggested that readily available carbohydrate introduced into the post-ruminal alimentary tract is utilized by ruminants as ffectively as by non-ruminants.
