This study was carried out to evaluate the effects of supplementary diet in infants. Influence of appropriate dietary habits on infants was also examined by being applicable to diets fortified chewiness as a means of intervention. The iron supplementary diet was supported to the healthy infants twice a day for three months. Measures of hemoglobin, hematocrit, RBC count, serum iron, TIBC, ferritin, development examination, and dietary intake patterns of experimental group (n = 25) and control group (n = 20) were performed before and after the intervention. The amount of iron intake from the supplementary diet in the experimental group was $1.77{\pm}0.80 {\cal}mg/day$. After the intervention period, the experimental group not only had increased intakes of grains also decreased intakes of milk. Outcomes observed in infants receiving iron intervention showed that the improved trend of excessive milk intakes and the possibility as a regular diet by serving the iron supplementary diet which can apply to main dish. All measures in blood did not provide significant differences except TIBC between the experimental and the control group before the intervention. But, after the intervention, the experimental group improved most levels of measures, especially significance in hemoglobin, but serum iron. Development of two groups did not differ significantly and both groups were in the range of normal infants' development. However, the levels of MDI and PDI evaluated by BSID-II in the experimental group were slightly higher than the control. Furthermore, the development of cognitive and languistic function was associated with infant growth in the experimental group. In conclusion, this research demonstrated that the iron supplementary diet could affect the iron status and the development of infants despite low-dose supplementation of iron.

Zinc is one of the essential trace elements in the living organism for growth and health. The first identified metalloenzyme, carbonic anhydrase, is a zinc compound and several others have been described since. Among zinc deficiency syndromes in animals porcine parakeratosis has been successfully treated with zinc supplements, and in man a syndrome of anemia, hypogonadism, hepatosplenomegaly, and dwarfism, prevalent in parts of Iran and Egypt, has been ascribed to lack of zinc in the diet. Dietary zinc excess in the rat is manifested by a hypochromic, microcytic anemia, poor growth, reduction in liver catalase and cytochrome oxidase. The present study is an attempt to delineate the changes of tissue contents of trace elements, especially of iron, copper and zinc in liver and kidneys of the rats. Weanling albino rats, weighing 60 to 80gm. were used in this experiments. The rats were housed in cages with aluminum floors and received feed and distilled water ad libitum. Animals were divided into three groups, control, low zinc diet and high zinc diet groups. The high zinc diet group was subdivided into 0.5% Zn and 0.7%Zn groups. The supplementary copper or iron was added to the high dietary zinc groups. The animals were sacrificed and the tissues were washed several times with deionized water. The wet digested samples were analyzed by Hitachi Model 207 atomic absorption spectro-photometer for the determination of iron, copper and zinc in the liver and kidney. Hemoglobin level in the blood was measured by cyanmethemoglobin method. The results of this study are as follows: 1) All rats fed high zinc diets and low zinc diets gained less weight than control. Weight gain was not improved by the supplementary copper or iron and both. 2) Hemoglobin concentration was decreased significantly in the rats fed high zinc diets and less in the low zinc diet. Supplementary copper and iron to the higher zinc diet appeared to give some improvement of anemia. 3) The iron contents of the liver and kidneys were significantly decreased in the high zinc groups and the reduction was more significantly in the rats receiving higher zinc diet (0.7%). The supplementary copper caused a further depression of liver iron. On the other hand, the iron, added to the high zinc diet lessoned the severity of the decrease in liver iron and caused kidney iron to be maintained almost at the level found in the rats fed by zinc and supplementary copper diet. 4) High zinc diets did not change copper content of the liver and kidney. Supplementary copper elevated the concentration in the liver and kidney and added iron had no effect on the accumulation of copper in the liver and kidneys. 5) The high zinc diets caused marked increases of zinc content in the liver and kidney. Supplementary iron to the high zinc diet caused increases of zinc contents of liver and kidneys.

This study was carried out to investigate the supplementary effects of Suwon 464, which has over two times of dietary fiber content compared with normal rice (Ilpum), on blood glucose in diabetic mice. We supplied 5 kinds of experimental diets (corn starch diet as a control (CO), Ilpum polished rice diet (IP), Ilpum brown rice diet (IB), polished rice diet (SP) and brown rice diet (SB) of Suwon 464) to diabetic mice for 8 weeks, after analyzing dietary fiber contents of 5 experimental diets. Diet intake, body weight and contents of blood glucose, hemoglobin $A_{lc}$ and insulin were measured. The dietary fiber contents in CO, IP, IB, SP, and SB diets were 1.0, 1.2, l.4, l.4, and 2.0% respectively. Body weight was lower in SB group than the other groups though there was no significant difference in diet intake among experimental groups. The concentration of blood glucose in diabetic mice was lower in SB group than the other groups during the supplementary period of experimental diets. The hemoglobin Ale and serum insulin levels were lower in SP and SB groups. These results suggested that the brown rice of Suwon 464 with high dietary fiber can control diabetes in diabetic mice by reducing the blood glucose and hemoglobin Ale.

This study was carried out to investigate the supplementary effects of ${\gamma}$-oryzanol extracted from rice bran on lipid metabolism in diabetic mice. We supplied 2 kinds of experimental diets (CO without and GO with 0.2％ ${\gamma}$-oryzanol) to diabetic mice for 8 weeks. Diet intake, body weight, organ weight, contents of serum and hepatic lipid profiles, and fecal lipid levels were measured. Though there was no significant difference in diet intake, body weight change and organ weight between experimental groups, the concentration of serum total cholesterol and hepatic total lipid, total cholesterol and HMG-CoA reductase activity was significantly lower in GO group treated with 0.2％ ${\gamma}$-oryzanol of diet than CO group after supplementary period of experimental diets. And total lipid, triglyceride, total cholesterol, and bile acid levels excreted to feces were significantly higher in GO group than CO group. These results suggest that ${\gamma}$-oryzanol decrease the serum and hepatic lipid levels by lowing HMG-CoA reductase activity or increasing the contents of fecal lipid in diabetic KK mice.

Objective: The objective was to evaluate feed intake, digestibility, body weight change and carcass characteristics of sheep fed a basal diet of hay supplemented with banana leaves and silver leaf desmodium. Methods: Thirty yearling lambs with an average initial body weight of $15.85{\pm}1.6kg$ were grouped into six blocks of five rams in each block. The treatments were: hay alone (T1), hay+100% banana leaf (T2), hay+67% banana leaf+33% desmodium leaf (T3), hay+33% banana leaf+67% desmodium leaf (T4), andhay+100% desmodium leaf (T5). Three hundred grams of treatment diets were offered daily on as fed basis. The feeding and digestibility trials lasted for 84 and 7 days, respectively, followed by carcass evaluation. Results: The total dry matter (DM) intake for T3, T4, and T5 were greater (p<0.05) than those fed T1 and T2 diets. The lowest (p<0.05) organic matter (OM) intake was recorded in rams reared on T1 diet. The total crude protein (CP) intake was in the following order: T5>T4>T3>T2>T1. Ram lambs receiving supplementary diets had higher (p<0.05) DM, OM, CP, neutral detergent fiber and acid detergent fiber digestibility compared with the control diet. The empty body weight and slaughter weight was highest (p<0.05) in rams receiving T3, T4, and T5 diets. The average daily gain and feed conversion efficiency was highest (p<0.05) in rams receiving the supplementary diets. The dressing percentage on the basis of hot carcass weight linearly increased with increasing levels of desmodium. Rams reared on supplementary diet had higher (p<0.05) rib eye area compared with the control diet. Conclusion: In conclusion, when banana leaf is used as a supplement to poor quality grass, better body weight gain was obtained when fed in combination with desmodium.

The effects of common Korean dietary fiber-rich foods(dried sea mustard, Lentinus edodes and Korean radish leaves) on total gut transit time of diet, serum cholesterol level and mineral apparent absorption ration and tissue level were investigated. Twenty eight male were divided into 4 groups and were fed a control diet(containing 2% cellulose) and three fiber supplementary diet mixed with 10% of the above dietary fiber rich foods for 4 weeks, respectively. Body weight gain and food efficiency ration were not affected by the supplementary diet of fiber but the total gut transit time of diet was shortened in all dietary fiber groups. The Lentinus edodes reduced significantly serum total cholesterol and increased the HDL-cholesterol/total cholesterol ratio at 4th week without and effect on calcium and iron apparent absorptions and tissue levels of the minerals. Radish leaves decreased significantly iron apparent absorption ration with a tendency to increase iron retention in spleen and did not alter serum cholesterol level. Serum cholesterol concentration and calcium and iron apparent absorptions were not significantly altered by the ingestion of sea mustard, while it had more soluble dietary fiber than mushroom and radish leaves.

This study was performed to study the effects of Gastrodiae rhizoma on lipid concentration of serum and liver in rats fed high fat diet. Male Sprague-Dawley rat were randomly assigned to 5 groups such as basal diet only(BDG), high fat diet(HFG) and high fat diet with 5% processed Gastrodiae rhizoma(GRL), high fat diet with 10% processed Gastrodiae rhizoma(GRM), high fat diet with 15% processed Gastrodiae rhizoma(GRH) supply each of the experimental diets for 6 weeks. Food intake was significantly decreased by both high fat intake and high fat with Gastrodiae rhizoma intake compared with basal diet intake but weight gain was not significantly different from each groups. Liver weights were significantly lowered by Gastrodiae rhizoma intake compared with high fat intake. In the serum, total cholesterol was not significantly different with each groups, but triglyceride level was significantly lowered by Gastrodiae rhizoma intake as compared with control. In the liver, lipid levels inceased with the Gastrodiae rhizoma intake, but total cholesterol and triglyceride levels were not significantly different with control. These results showed that dietary Gastrodiae rhizoma as supplementary food may decrease triglyceride in the serum.

An experiment was conducted to determine the effects of supernormal level of copper (Cu) from different supplementary sources on the performance, cholesterol level in plasma and breast muscle, and accumulation of fat and Cu in broilers. In a 5 wk feeding trial, two hundred forty hatched male broiler chickens were assigned to four dietary treatments: control diet containing 10 mg/kg supplementary Cu, control diet plus 250 mg/kg Cu from $CuSO_4$ ($CuSO_4-250$), control diet plus 125 mg/kg Cu from Cu-methionine chelate (Cu-Met-125), and control diet plus 250 mg/kg Cu from Cu-methionine chelate (Cu-Met-250). Weight gain in Cu-Met-125 treatment and Cu-Met-250 treatment were not different, but they were significantly (p<0.05) greater than that in $CuSO_4-250$ treatment. Plasma total cholesterol and reduced glutathione (GSH) in blood were significantly reduced by supplementation of $CuSO_4-250$, but were not significantly affected by Cu-Met supplementations. Plasma HDL cholesterol, plasma triglycerides and breast muscle cholesterol were not significantly affected by Cu supplementation. $CuSO_4-250$ improved metabolizability of crude fat, which resulted in low abdominal fat pad weight. Cu from Cu-Met was better absorbed and accumulated more in the breast muscle and lesser in the liver compared with Cu from $CuSO_4$.

Cooked soybean, soybean curd, soymilk residue and fermented soybean Meju products were prepared in the laboratory and the protein supplementary effect of these foods to the rice diet was determined by the rat feeding experiments. The soybean products providing 20% of the dietary protein were added to steamed rice and the protein digestibility (TD), Biological Value(BV), NPU, PER and Partial Carcass Nitrogen Value of the diets were measured. The protein supplementary effect of soybean products indicated that the non-fermented products generally improved the protein quality of the rice diet, whereas the fermented products did not but reduced it in some cases. There was observed a possible antinutritional effect for the diet supplemented with Home-made Meju. This growth retarding effect of Home-made Meju disappeared during the subsequent ripening in the brine for 6 months.
