Broilers were fed diets supplemented with various levels of a probiotic (mixture of the following direct-fed microorganisms: Lactobacillus, Bacillus, and Streptococcus). Growth performance, abdominal fat, excreta, and litter ammonia level were determined. The results showed that birds fed the probiotic-supplemented diets had better weight gain (p < 0.01) and feed conversion (gain:feed;p < 0.12) when compared to the birds fed the unsupplemented diet. No differences in feed intake and abdominal fat were observed among birds fed the different experimental diets. Excreta (p < 0.05) and litter (p < 0.01) ammonia levels were reduced by dietary probiotic supplementation. A dosage of 0.25 g of the probiotic/kg of diet is needed to maiximize growth performance during both the starter and finisher periods. A higher dosage (approximate 0.5 g/kg) is needed to minimize litter ammonia production.

The purpose of this study is to investigate the nutritional status and dietary intake of gastrectomized cancer patients. For this study, from 1993. 1 to 1993. 8, 50 postoperative gastric cancer patients were selected to examine anthropometric and laboratory data(Body Weight, Body Fat, serum Albumin, Total Lympocyte count), and dietary intake related symptoms. The results were 1) All anthropometric and laboratory data were significantly deteriorated by gastrectomy(s-Albumin, TLC. Body Fat : p<0.001). Weight loss of gastrectomized patients was 8.23$\pm$3.72% from admission to discharge. 2) In many gastrectomized cancer patients, preoperative dietary intake was decreased by abdominal discomfort, indigestion, early satiety, and anorexia. 3) Postoperative energy intake was 602$\pm$158㎉, and it is correspond to 31.18$\pm$.90% of daily energy requirement(1918$\pm$236㎉). The cause of poor oral intake is mostly fear, abdominal distension and fullness, and early satiety. In consideration of the fact that an inadequate energy intake was the main cause of the decreasing nutritional status, a careful nutritional care and dietary education is necessry after gastrectomy.

Poultry feeding systems are likely to change for increased efficiency of production. An experiment was conducted to compare the response of broilers to choice feeding of corn with a standard broiler ration. The treatments consisted of providing broiler feed as the only feed (SINGLE FEED) and access to corn as a choice to a complete broiler feed (CHOICE FEEDING). Weights and feed consumption were obtained at weekly intervals. Samples at the conclusion of the experiment were taken to determine the weight of abdominal fat. Results showed that there was no significant difference in term of liveweight between the two feeding regimes. However, birds given a choice of the broiler feed and corn had better feed efficiency which is reflected by the lower total feed intake. Corn intake was 23.1% of total feed intake in the choice fed birds. In term of carcass colour, birds fed corn as a choice was observed to have a deeper yellow skin colour than the birds fed with broiler feed only.

The carcass characteristics and composition of both male and female commercial broiler chickens (CB) and the red jungle fowl (RJF) were compared at a common body weight of $800{\pm}25.6g$. The RJF and CB were 133 and 17 d of age, respectively, when they reached 800 g. The yields of breast and thigh portions and their muscle to bone ratios were higher for RJF as compared to CB. On the other hand, the latter had significantly greater hearts, livers and gizzards. The weights of the whole thigh and drumstick, and their muscles were lower in females than males. The CB had more abdominal fat than RJF. While sex had no significant effect on the absolute weights of abdominal fats in CB, the female RJF were fatter than their male counterparts. The fat and cholesterol contents of the breast and leg muscles of CB were significantly higher than those of RJF. The opposite was noted for protein content of both muscles. The effect of sex on fat and cholesterol contents varied according to muscle type. Comparison of CB and RJF at a common body weight suggested that the rate of development of body components have changed concomitantly with selection for rapid growth in the former.

Objective: Obesity is closely related to several factors such as genetic factors, energy intake and energy expenditure. It was said that alcohol & food habits were important to formation of obesity. The purpose of this study are to find out the alcohol & food habitual characteristic of obese adult men and to promote the health of these men. Method: From May, 2000 to November, 2001, We collected 75 eases obese patients, who visited to the Health Examination Center Dept. of Kangnam oriental medicine hospital, Dongguk University who took the health examination, and control group who were matched by age and sex. We investigated the alcohol & food habits by questionnaire. Results and Conclusions: 1. The patients over BMI 25 were in excess of the standard of obesity such as Modified Broca $^{\circ}{{\O}}s$ Index. Percent Body Fat, Abdominal Fat Distribution. But, the patients below BMI 20 were normal range of obesity degree. 2. Abdominal Fat Distribution was increased according to age and physical activity was decreased in obese group. 3. The mean of total calory by alcohol in a month was 4324.6kcal in obese group while control group was 2206.8kcal. 4. In the comparison of food habit, obese group is higher than control group in 7 articles of the 13 articles which influenced obesity.

We evaluated the effect of the ginsenoside Re on insulin resistance of glucose transport in muscles of rats made insulin resistant with a high fat diet. After a week of adaptation period to the laboratory environment, 40 male wistar rats were randomly assigned into 2 groups (Chow diet group; CD, n = 20, High fat diet group; HFD, n = 20). After 5-week of high fat diet, Food was removed after 6:00 PM the day before the experiment. The following morning, rats were anesthetized by an intraperitoneal injection of pentobarbital sodium (50 mg/kg body wt), and the soleus muscles were removed. Before incubation, the soleus muscle was split longitudinally into strips with an average weight of 15~20 mg. After the muscle dissection was completed, the abdominal cavity was opened, and the epididymal, mesenteric, and retroperitoneal fat pads were removed and weighed. Treatment of muscles with ginsenoside Re alone had no effect on glucose transport. The high fat diet resulted in ~50% decreases glucose transport rate in soleus muscles. Treatment of muscles with ginsenoside Re in vitro for 90 min completely reversed the high fat diet-induced insulin resistance of glucose transport in soleus muscles. This effect of ginsenoside Re is specific for insulin stimulated glucose transport, as Re treatment did not reverse the high fat diet-induced resistance of skeletal muscle glucose transport to stimulation by contraction. Our results show that the ginsenoside Re induces a remarkably rapid reversal of high fat diet-induced insulin resistance of muscle glucose transport.

Objective: We investigated the efficacy of a 12-week supplementation of soy isoflavone with L-carnitine on the development of obesity in high fat-induced obese C57BL/6J mice, which are known as a good model of diet-induced obesity. Methods: We measured body weights, adipose tissue mass, serum/liver lipid profiles and fat cell size/number in C57BL/6J mice fed diets containing either low fat (4%) or high fat (35%), or high fat supplemented with soy isoflavone powder containing 10% isoflavone and L-camitine for 12 weeks. Results: Body weight gain, abdominal adipose tissue and liver weight were lower by 31% 78% and 31.4% respectively, in mice on high fat diet containing soy isoflavone+L-carnitine (SC mixture) compared with high fat diet group. Also, SC mixture improved serum lipid profiles such as total cholesterol (TC), triglycerides (TG), and liver lipid profiles such as total lipids and TG. As subsequent results, this SC mixture prevented high-fat diet from accumulating TG in the liver. The size of fat cell was also significantly decreased in SC mixture fed mice. At the end point of this experiment, our results showed that feeding with soy isoflavone for 12 weeks finally increased camitine palmitoyltransferase 1 (CPT 1) activity through elevating the level of CPT1 expression. Conclusions: This study suggests that long-tenn supplementation with dietary soy isoflavone and L-carnitine is more synergistically beneficial for the suppression of high-fat diet induced obesity by inhibiting liver TG accumulation and the gain in abdominal adipose tissue weight than that with soy isoflavone. The antiobesity effects of SC mixture might be attributed, at least in part, to the induction of fatty acid catabolism by soy isoflavone, genistein.

Excessive fat deposition, particularly in the abdominal region, has become a problem in broiler production. When the caloric intake exceeds the body demands for energy, excess food is stored as fat in broilers. Researchers have shown that fat deposition varies with breed, strain, sex age, nutrition, exercise, ambient temperature and rearing systems. These factors affect fat deposition through their effects on the size or the number of adipose cells or a combination of both. In some measurements on live birds to predict body fat, the wet weight and percentage fat of skin in pectoral feather tract are significantly correlated with percentage abdominal fat. But these correlation coefficients are not so high. Therefore, correlation coefficients indicate that these measurements on live birds ate not useful for estimating body fat weight and percentage. Most reports show that an increase in the proportion of carcass fat, when measured at a given age, is correlated with selection for increased body weight. On the other hand some research results show that selection for body$.$weight gain dose not lead to an alteration in the proportion carcass fat when measured at a given body weight. Besides, selection for improved food conversion efficiency alone resulted in a decrease in carcass fat and an increase in protein and water when measured at either a given age or body weight, Thus eventhough it is uncertain whether carcass fat is increasing as a result of body-weight selection in broilers: however it is clear that selection for improved food conversion efficiency, either alone or in combination with growth rate, should result in leaner carcasses than selection for growth rate alone.

Two hundred and eighty-eight 21-week-old Hyline Brown laying hens were randomly allotted to 9 treatments, 32 birds for each treatment. A 3${\times}$3 (chromium${\times}$L-carnitine) factorial experiment was designed to investigate the single and interactive effects of adding yeast chromium (0, 400 and 600 ${\mu}g/kg$) and L-carnitine (0, 50 and 100 mg/kg) to corn-soybean diets on lipid metabolism of laying hens for 7 weeks. The results showed that 600 ${\mu}g/kg$ chromium or 100 mg/kg L-carnitine had significant effects on most indices of lipid metabolism (p<0.05 or 0.01). There were significant interactions on the concentration of liver triglycerides, egg yolk cholesterol, abdominal fat percentage between chromium and L-carnitine (p=0.0003-0.0500). Adding 400 ${\mu}g/kg$ chromium and 100 mg/kg Lcarnitine simultaneously was the best for reducing egg yolk cholesterol and adding 400 ${\mu}g/kg$ chromium and 50 mg/kg L-carnitine at the same time was the best for reducing abdominal fat percentage. There was no side effect on production performance of laying hens while chromium or (and) L-carnitine reduced liver lipid, abdominal fat and egg yolk cholesterol.

Objectives: Obesity is chronic condition which can severely influence health. People with a high percentage of body fat (%BF) have high prevalence of hypertension and hypercholesterolemia. Abdominal obesity (AO) seems to play a major role in the development of cardiovascular disease, diabetes and hyperlipidemia. This study investigated the %BF and AO of workers in the automobile manufacturing industry. Methods: The subjects were categorized by sex, age, job class, drinking history and smoking history. %BF and AO were measured by using bioelectrical impedance analysis (Jawon Medical, Seoul, Korea). We analyzed the relationship between age, sex, job class, drinking history, smoking history and %BF and WHR into frequencies, $X^2$-test using the SPSS Ver. 12.0. Results: Regarding the relationship between sex and %BF, AO, there was statistically significant difference as men had a significant higher level of %BF and AO than women. There was a positive correlation between age and both %BF and AO. Workers in their 40s especially ran level of AO up. In job class, office workers were apt to have a higherlevel of %BF and AO than production line workers. %BF and AO of the non-drinker group showed a lower level than the drinker group. On the other hand, the ex-smoker group had higher levels of %BF and AO than the non-smoker or current-smoker groups. Conclusions: The above results showed that men, the advanced in years, office workers, drinkers and ex-smokers had high levels of %BF and AO.
