以含碳水化合物50%以上的饲料饲养家畜,生长正常,但给鱼类投喂含高碳水化合物的饵料,一般生长缓慢。为什么高碳水化合物的饵料对鱼类生长不利呢?其主要原因,据称是由于鱼类的碳水化合物消化酶活性低,随着饵料中碳水化合物含量的增加,不仅碳水化合物,而且蛋白质的消化率也降低之故。最近,还认为鱼类属潜在性的糖尿病体质,糖代谢机能弱,不能有效地利用已吸收的碳水化合物是其主要原因。糖代谢机能不良的病有糖尿病。糖尿病可根据与葡萄糖负荷相对应的血糖与血浆胰
To feed livestock containing more than 50% carbohydrate, grow normally, but feeding fish containing high carbohydrate feed, the general slow growth. Why is high carbohydrate feed unfavorable to fish growth? The main reason is said to be due to low activity of fish carbohydrate digestive enzymes, with the increase of carbohydrate content in the diet, not only carbohydrates, and protein digestibility It is also reduced. Recently, it has also been suggested that fish are potential diabetic entities with poor glucose metabolism and are not responsible for the efficient use of absorbed carbohydrates. Diabetes mellitus is a disorder of poor glucose metabolism. Diabetes can be based on the glucose load corresponding to the blood glucose and plasma pancreas
