1.在青春期公鸡(体重1.5~2.0千克，12~20周龄)的基础上，注入10克粉碎的日粮和20毫升的水，以增加葡萄糖负荷和葡萄糖、山梨醇和氯化钾的高渗溶液。所有这些都导致了在接下来的3小时内食物摄入量的显著减少。2.在十二指肠输注山梨醇和氯化钾高渗溶液3OSM时，1小时内的摄食量显著减少。葡萄糖输注仅在实验前饥饿3小时的禽类中减少摄入量。3.结果与输液部位和营养内脏控制摄食量的机制有关。很可能在十二指肠有一个主要的渗透控制，这可能会影响上胃肠道的二级控制系统。
1. Infusions of 10 g of diet mashed in 20 ml of water, increasing glucose loads and hypertonic solutions of glucose, sorbitol and KCl, were introduced into the crop of the adolescent cockerel (1.5 to 2.0 kg body weight and 12 to 20 weeks of age). All caused a significant reduction of food intake over the following 3-h period. 2. Duodenal infusions of hyperosmotic solutions of sorbitol and KCl at 3 osm significantly decreased food intake within an hour of infusion. Glucose infusion decreased intake only in birds starved for 3 h before the experiment. 3. The results are discussed in relation to the site of infusion and nutritive visceral mechanisms of food intake control. It is likely that there is a major osmotic control in the duodenum which may affect a secondary control system in the upper gastro-intestinal tract.
