穀食의 混食이 흰쥐의 成長에 미치는 影響

Abstract

The effect of three different grains supplemented diet as a dietary carbohydrate source on the growing rat, growth, food intake, FER, PER value, excretion of urinary and fecalnitrogen and glucose and the level of glucose and cholesterolin serum blood was studied. Fonty males and same number of females of Albino rats weighing ♀582g, ♂622g were divided into eight experimental group, five male and female in each. The rats have been fed for 14 weeks with eight different diet: 100% rice diet group, 85% rice diet supplemented with15% barley, 70% rice diet supplemented with 30% barley,55% rice diet supplemented with 45% barley, 85% rice dietsupplemented with 15% wheat, 70% rice diet supplemented with30% wheat, 55% rice diet supplemented with 45% wheat, and sugar-casein for the control group. Under this condition wheat supplemented diet group shows the best FER PER value and body weight gain value. Especially in female group shows better FER, PER and body weight gain value compare to control diet groups, Under the male groups wheat supplemented diet group shows lower FER, PER and body weight gain value compare to the control group but higher than those of barley diet grouper rice alone. In female group the nitrogen retention shows also highest value by wheat supplemented diet group. By male group the wheat supplemented diet group shows not better value compare to the control group, but higher than barley supplemented group or rice alone. The nitrogen excretion through feces was significantly higher by grain supplemented diet group compare to the 20%casein sugar diet. The blood total cholesterol content was slightly decreased by the control group which was fed disaccharide, compare to grain groups which were fed polysaccaride. But the free cholesterol to esterified cholesterol ratio shows Lower value by control group than grain groups axceptthe 70% rice supplemented with 30% barley group. ※ Wheat : processed wheat
