Two experiments were conducted in central Vietnam to test the hypothesis that supplementation with a concentrate, comprising rice bran (45% fresh basis), maize (49%), fish meal (3%), urea (2%) and salt (1%), up to 2% of live weight (LW)/d (dry matter (DM) basis) would linearly increase digestible organic matter intake and LW gain of yellow cattle. In both experiments, there were five treatments, namely a basal diet of fresh grass fed at 1.25% of LW (experiment 1, elephant grass, Pennisetum purpureum; experiment 2, native grass) and rice straw (Oryza sativa) fed ad libitum or this diet supplemented with concentrate at about 0.3, 0.7, 1.3 or 2.0% LW. There were 4 male growing cattle per treatment in experiment 1 and 3 in experiment 2. Diets were fed for 44 (experiment 1) or 49 (experiment 2) days, with feed intake recorded daily, LW measured about weekly and digestibility measurements made over 7 days commencing on day 24 (experiment 1) or day 10 (experiment 2). The elephant grass and native grass had neutral detergent fibre (NDF) concentrations of 82 and 73% DM, and nitrogen concentrations of 1.3 and 1.8% DM, respectively. The rice straw used had a NDF concentration of 79-84% DM and nitrogen concentration of 0.8% DM. The concentrate had NDF and nitrogen concentrations of 33 and 2.8% DM. In both experiments, DM intake increased (p<0.001) linearly as the amount of concentrate consumed increased. Rice straw intake declined (p<0.001) (experiment 1: 1.24 to 0.48 kg DM/d; experiment 2: 0.95 to 0.50 kg DM/d) as concentrate intake increased. Grass intake was not significantly affected by concentrate intake in either experiment. The lowest amount of concentrate supplement increased forage intake, after which substitution rate increased as the amount of concentrate consumed increased. However, substitution rates at the highest amount of concentrate consumed were modest at 0.3 to 0.5 kg DM reduction in forage intake/kg DM supplement consumed. In both experiments, digestible organic matter intake increased linearly (p<0.001) (experiment 1: 1.16 to 2.38 kg/d; experiment 2: 1.30 to 2.49 kg/d) as the amount of supplement consumed increased, as did LW gain (experiment 1: 0.15 to 0.81 kg/d; experiment 2: 0.15 to 0.77 kg/d). This was associated with significant (p<0.01) linear increases in organic matter intake and apparent organic matter digestibility. Neutral detergent fibre digestibility declined as concentrate intake increased, but the effect was not significant (p = 0.051) in experiment 2. These results are discussed in relation to existing literature and potential to improve the profitability of cattle fattening in central Vietnam.

We designed a 16-week feeding experiment to test the effects of dietary supplementation with distillers' dried grain (DDG) on the growth, feed utilization, and body composition of juvenile muddy loach Misgurnus anguillicaudatus. Seven isonitrogenous and isocaloric diets were formulated to contain 0% DDG (Control); 10%, 20%, and 30 % DDG from rice (diets RM10, RM20 and RM30); and 10%, 20%, and 30% DDG from rice and wheat flour (diets RWM10, RWM20 and RWM30), respectively. Three replicate groups of juvenile muddy loach averaging $1.5{\pm}0.10$ g were fed one of the diets to satiation twice daily. Survival of juvenile muddy loach fed the RWM20 and RWM30 diets was higher than that of the control group (P<0.05), while weight gain tended to decrease when fish were fed diets containing DDG. Weight gain of fish fed the RWM10 diet was greater than that of fish fed other diets, but the RM30 diet resulted in less weight gain than did the control (P<0.05). The feed and protein efficiency ratios of fish fed the RM10, RM20, RM30, RWM10, RWM20 and RWM30 diets were all similar to the control (P>0.05). Neither daily feed intake nor proximate composition of the whole body was affected by dietary DDG (P>0.05). The compositions of isoleucine, leucine, lysine, threonine, and valine were all elevated in fish fed the RM30, RWM10, RWM20 and RWM30 diets relative to those of other groups (P<0.05). In contrast, methionine + cystine and phenylalanine + tyrosine were all lower in fish fed the RM30, RWM10, RWM20 and RWM30 diets, as compared to those of other groups (P<0.05). Our results suggest that DDG is suitable as a partial replacement for soybean meal and wheat flour, and could be used at a rate of up to 20% for rice, or 30% for rice and wheat flour, for optimum growth performance of juvenile muddy loach.

An experiment was conducted with eight growing sheep (average initial weight 20.6 kg and average final weight 23.7 kg) in a $4{\times}4$ Latin square design to study the effect of type of forage supplementation to a basal diet of rice straw (ad libitum) and cassava (Manihot esculanta, approximately 9 g of dry matter $(DM).kg^{-0.75}{\cdot}day^{-1}$) on voluntary intake, digestion, rumen microbial protein synthesis and daily weight gain. Forages used were Leucaena (L, Leucaena leucocephala), Gliricidia (G, Gliricidia maculata) and Tithonia (T, Tithonia diversifolia, wild sunflower) at a DM supplementation level of approximately $13g.kg^{-0.75}.day^{-1}$. Organic matter intake was 40.4, 55.5, 55.0 and $54.9g{\cdot}kg.^{-0.75}{\cdot}day^{-1}$ for control (C, ad libitum straw and cassava), L, G and T. respectively, significantly lower for C than for the supplemented diets. Intake of supplementary forage had also a significantly positive effect on voluntary rice straw intake. All forage supplemented diets showed a significantly higher whole diet organic matter digestion than C ($488g{\cdot}kg^{-1}$), while T ($557g{\cdot}kg^{-1}$) differed significantly from L ($516g{\cdot}kg^{-1}$) but not from G ($526g{\cdot}kg^{-1}$). Daily weight gain was -1.7, 5.2, 5.4 and $4.7g{\cdot}kg^{-0.75}$, for C, L, G and T. respectively, significantly lower for C than for the forage-supplemented diets. Efficiency of microbial protein synthesis estimated from urinary excretion of purine derivatives was lower for C (3.8 g microbial N. (kg digestible organic matter intake $(DOMI))^{-1}$ than for the forage supplemented diets (11.3, 9.0 and 9.4 g microbial $N.(kg\;DOMI)^{-1}$ for L, G and T. respectively).

This study was based on the information provided by 1,180 elementary school children (630 boys and 550 girls) of 5th or 6th grade in Changwon and Gimhae of Gyeongnam province. They were asked about perception and preference for rice foods by questionnaires. The purpose of this survey was to find the way of encouraging rice intake and preference which is currently getting lower because of increasing simple westernized eating habits, and to provide basic information needed for inheriting and improving our traditional rice-based dietary culture. The results are summarized as follows. Most of subjects (91.2%) thought that steamed rice is better than bread for own health. The reason why they chose to eat steamed rice was 'because it is good for health' (61.2%), and 'because it is staple food item that we eat everyday' (26.4%). Seventy one percent of girls and 52.7% of boys gave the answer 'because it is good for health' as the reason for eating steamed rice. The reasons for the importance of the rice-based dietary culture were 'because of its superior nutritional value' (40.8%), and 'because it is our traditional eating culture' (28.6%). While significantly more girls (42.9%) answered as 'because of its superior nutritional value', more boys (39.0%) answered as 'because it is our traditional dietary culture'. More boys (59.0%) preferred noodles than girls' (54.7%), and fruits were preferred more by girls than boys as substitution foods for steamed rice showing significant difference (p<0.01). They wanted rice product developed in the forms such as Ssalamyun (29.8%), Ssalmandoo (24.1%), rice noodles (20.6%), and rice bread (15.6%). The preference score on rice products of subjects was one dish meals (4.27) and drinks (4.26), snacks (3.72), convenience foods (3.61), and steamed rice (3.44) in order. Preferred food showing points over 4 were Ssalbap (plain steamed rice) (4.29) in steamed rice type food, Kimchi bokeumbap (4.56), Bokeumbap (4.55), Bibimbop (4.45), Omelet rice (4.44), Kimbap (4.42), Ddukkuk (4.33), Curried rice (4.33), Jajangbap (4.28), and Ddukmandookuk (4.24) in one dish meal type food, Samgak Kimbap (4.26) in convenience type food, Songpyun (4.48), Injulmi (4.18), Teokbokki (4.71), Ddukkochiguyi (4.46), and rice cookies (4.24) in snack type food, and Shikhye (4.61) and Misugaru (4.28) in drink type food. Based on these results, it may be said that elementary school children think the rice-based diet is good for health and this dietary culture should be inherited and developed not only in a traditional aspect but also in a nutritional aspect. Therefore, more studies are needed to develop various forms of rice food products and cooking recipes.

An experiment was conducted to study the laying performance, shell quality, bone mineralization, hatchability of eggs and performance of progeny (weight at day one and 14 d of age, P content in day old chick, leg score and survivability of chicks) of synthetic broiler breeders fed different levels of non-phytate phosphorus (NPP). Six levels of NPP (1.2, 1.8, 2.4, 3.0, 3.6 and 4.2 g/kg diet) at a constant calcium (Ca) level (30 g/kg) in a maize-soya-deoiled rice bran based diet were tested. Levels of dicalcium phosphate, shell grit and deoiled rice bran were adjusted to achieve the desired levels of NPP and Ca. Each level of NPP was fed with a weighed quantity of feed (160 g/b/d) to 40 female broiler breeders from 25 to 40 weeks of age housed in individual cages. Each bird was considered as a replicate. Egg production, feed/egg mass, body weight, egg weight, shell weight, shell thickness, egg specific gravity, serum Ca content and tibia breaking strength were not influenced (p>0.05) by the variation in dietary NPP levels tested. Increasing the dietary levels of NPP did not influence the hatchability of eggs, phosphorus (P) contents both in egg yolk and day old chick, chick body weight at day one and 14 d of age, leg score and survivability of chicks up to 14 d of age. Maximum response ($p{\leq}0.01$) in shell breaking strength, tibia ash and serum inorganic P contents were observed at NPP levels of 2.09, 2.25 and 3.50 g per kg diet, respectively. The retention of Ca increased, while the P retention decreased ($p{\leq}0.01$) with increasing dietary levels of NPP. Though maximum responses in shell breaking strength, bone ash and serum inorganic P were observed at NPP higher than 1.2 g/kg diet, the broiler breeder performance in terms of egg production, shell quality, hatchability of eggs and progeny performance and their survivability was not influenced by dietary NPP concentrations. It is concluded that synthetic broiler breeders maintained in cages do not require more than 1.2 g NPP/kg diet with a daily intake of 192 mg NPP/b/d during 24 to 40 weeks of age.

This study was carried out investigate the effects of dietary addition of mineral and sugar on the dry matter intake, daily gain, yield grade and quality grade of Hanwoo (Bos taurus coreanae) steers. Three diets fed to steers included a control diet (concentrate mix and rice straw : C) and two treatments diet (control diet + black sugar 100 g + mineral 100 g : T1, and control diet + black sugar 150 g + mineral 50 g : T2). The results are summarized as follows; total feeding intake, body weight gain and daily gain did not show significant differences among the three treatments. Cold carcass weight was significantly (p<0.05) higher in T2 than in the other two treatments (C and T1). There was no significant difference in yield traits of back fat thickness, longissimus muscle area and yield grade among the three treatments (C, T1 and T2). Marbling score showed significantly (p<0.05) higher in order of T2 (5.67) > T1 (4.67) > C (3.67). Meat color, fat color, texture and maturity were no significant difference. Quality grade was higher in T2 than in the other two treatments (C and T1), but there was no significant difference. The results show that marbling score and quality grade of Hanwoo can be increased by high dry matter intake with feeding addition of mineral and sugar.

This survey was conducted to investigate the dietary behavior and health status of Buddhist nuns. In this study, 100 Buddhist nuns in Seoul were selected. The dietary survey was focused on the diet in winter. The age distribution was as follows; 24% of the subjects were in their 20s, 45% in their 30s, 23% in their 40s, and 8% in their 50's and over, respectively. The percentage of the subjects living in temples close to the downtown area was 77% and the rest resided in areas remote to the downtown area. Over fifty percent of the subjects were satisfied with their diet at temple. And 59% of the subjects were eating a snack more than once a day. The snacks included fruits (60%), raditional tea (20%), coffee (9%), bread and cookies (4%), md rice cakes (3%), etc. Among food groups, the intake of green-vegetables and fruits were the highest and intake of milk and bean products were low which may cause calcium and protein deficiency. Most of the subjects believed that their health conditions were average or above average. About 50% of subjects didn't exercise at all. The frequencies of gastro-intestinal diseases and anemia were extremely high. About 50% of subjects took some form of medicine. To improve their health and nutritional status, it is required that they practice a good dietary behavior, maintain a balanced diet, and exercise regularly.

This study aims to identify the dietary patterns relevant to obesity of Korean women among low income classes. Adults 20-64 years were used as study subjects from the data of 2005 Korea National Health and Nutrition Examination Survey. We compared obese and normal-weight women in terms of their nutrients intake, diet quality and food patterns. Diet quality was assessed by using the Nutritional Adequacy Ratio (NAR) and Index of Nutritional Quality (INQ). Our results showed higher prevalence of obesity among lower socioeconomic status women. In men, there were no significant associations with socioeconomic status and prevalence of obesity. Higher risk of nutritional inadequacy was observed among obese women compared to normal weight women. Obese women showed significantly lower INQ for nutrients such as Ca, Fe, Vitamin A, Thiamin, Riboflavin and Vitamin C compared to other women. They consumed significantly higher amount of rice (p < 0.05) and lower amount of vegetables (p < 0.01). By contrast, obese men from low income classes showed higher intake of those nutrients. Obese men also consumed significantly higher amount of meats than normal weight men. Therefore, this study suggests that gender-specific approaches based on economic situation should be considered in developing the intervention program for managing obesity for low income classes.
