This study was carried out to determine the effects of free choice feeding of starter feed and whole cereals on the growth of turkey poults. Two hundred-seventy poults (7-d old) were divided into 3 treatment groups each with 3 replications containing 15 males and 15 females. Control poults (C) were fed only on starter feed (280 g CP and 11.7 MJ ME/kg). Treatments for choice-fed turkey poults were offered a choice of a starter feed and wheat (120 g CP and 12.3 MJ ME/kg) for wheat selecting (WS) or maize (83 g CP and 13.9 MJ ME/kg) for maize selecting (MS) group in separate feeders. Final live weight (2,280.7 g for the C vs. 2,374.3 and 2,324.6 g for the WS and MS), daily gain (39.21 g vs. 40.87 and 39.99 g) and total feed intake (95.2 g vs. 103.2 and 97.9 g) in the WS poults were significantly higher (p<0.05) than those of the C group, but feed conversion ratio was not significantly different between the treatments. The proportional intakes of cereals vs. total feed intake were 11% in both the WS and MS group. The amount of protein intake in the C group (280 g CP/kg diet) was significantly (p<0.05) higher than that in WS and MS groups (263 and 259 g CP/kg diet, respectively) whilst the ME intake in the C group (11.7 MJ/kg diet) was significantly (p<0.05) lower than that in MS group (11.9 MJ/kg diet). Our results showed that turkey poults fed starter feed and whole wheat in a free choice feeding system have a higher efficiency in terms of daily gain, final live weight, and an economic advantage may be obtained from free choice feeding due to a reduced protein intake and feed cost.
This study was conducted to identify dietary factors that may affect the occurrence of gastric cancer in Koreans. Preoperative daily nutrition intake and diet quality of patients diagnosed with gastric cancer were evaluated. Collected data were comparatively analyzed by gender. The results were then used to prepare basic materials to aid in the creation of a desirable postoperative nutrition management program. The subjects of this study were 812 patients (562 men and 250 women) who were diagnosed with gastric cancer and admitted for surgery at Soonchunhyang University Hospital between January 2003 and December 2010. Nutrition intake and diet quality were evaluated by the 24-hr recall method, the nutrient adequacy ratio, mean adequacy ratio (MAR), nutrient density (ND), index of nutritional quality (INQ), dietary variety score (DVS), and dietary diversity score (DDS). The rate of skipping meals and eating fast, alcohol consumption, and smoking were significantly higher in males than those in females. The levels of energy, protein, fat, carbohydrate, phosphorous, sodium, potassium, vitamin $B_1$, vitamin $B_2$, niacin, and cholesterol consumption were significantly higher in males than those in females. Intake of fiber, zinc, vitamin A, retinol, carotene, folic acid were significantly higher in females than those in males. MAR in males was significantly higher (0.83) than that in females (0.79). INQ values were higher in females for zinc, vitamin A, vitamin $B_2$, vitamin $B_6$, and folic acid than those in males. The average DVS was 17.63 for females and 13.19 for males. The average DDS was 3.68 and the male's average score was 3.44, whereas the female's average score was 3.92. In conclusion, males had more dietary habit problems and poor nutritional balance than those of females. Our findings suggest that proper nutritional management and adequate dietary education for the primary prevention of gastric cancer should be emphasized in men.
Ninety-three weaning children, 8-36 Mo. old wererandomly selected from rural areas of South Korea. Food and nutrient intake level were measured by the weighing-interview method for two consecutive days in December 1976. Their weaning pattern, dietary pattern, food and nutrient intake level were analyzed. A brief summary of 4he finding follows; 1) 80% of the rural children completed the weaning by the age of 24 months. 2) 44% of 8-12 month olds were living only on breast mil while the rest of the age group received regularly a supplementary food. 3) Over half of the 8-36 Mo old children investigated were receiving the same dietary pattern, arbitrarily called 'Diet K'. Diet K consists of rice-Kimchi-seasoning-oil which is the basic components of an average Korean adult diet. This very composition of the diet K and no other variety of food included inevitably result in low intake of vitamin A, iron, calcium and riboflavin for the children. 4) The weaning children were found to be taking all nutrients except niacin in amount far from sufficient to recommended level. Particularly low were the intakes of good quality protein, iron, vitamin A, riboflavin and vitamin C which met only 15%-37% of the recommended level for 12-36 Mo. olds. 5) It was concluded that majority of the rural children of weaning age in Korea are given the simple diet K and feeding the weaning children only with the basic dietary pattern of adults can not meet the nutritional requirements. This is a part of the study supported by the ROKG/USAID Health Planning Project.

Ninety lactating goats (Bachthao, Barbary, Beetal and Jamnapary breeds) were used in an experiment to investigate the replacement value of the tree fodders Flemingia (Flemingia macrophylla) and Jackfruit (Artocarpus heterophyllus). The foliages were used to replace the concentrate in diets based on chopped whole sugar cane (Sacharatum sp.), Para grass (Brachiaria mutica) and dried cassava root (Manihot esculanta). The concentrate was replaced by foliage of Jackfruit or Flemingia at 0%, 20%, 40%, 60% and 80% based on the crude protein (CP) content in the concentrate and foliages, respectively. Average milk yield was 1,617 g/day for goats fed Jackfruit compared to 1,532 g/day for those fed Flemingia. Increasing amounts of Flemingia foliage resulted in reduced dry matter intake and decreased milk yield but milk composition (CP, casein and fat content) was similar up to 60% replacement. Flemingia showed a poor potential as a supplement for lactating goats and replacement levels should not exceed 20% of the protein in the concentrate or 7.5% of the dry matter in the diet. With respect to the combination of milk production and net return over the control a CP replacement rate of 20% was the most promising. For Jackfruit there was similar feed intake and milk yield at a replacement level of 20% of CP in the concentrate (9.2% of DM intake) compared to the control diet. Milk yield at the level of 40% replacement (15% of the DM) in the diet was slightly reduced. Up to a level of CP replacement rate of 60% (21% DM in the diet) can be suggested for on-farm testing as a higher net return over the control was obtained on station.
BACKGROUND/OBJECTIVES: This study aims to develop a mobile nutritional management program for integration into the already developed web-based program, Diabetes Mellitus Dietary Management Guide (DMDMG) for diabetic patients. Further, we aim to evaluate the amended DMDMG program. SUBJECTS/METHODS: The mobile application based on an Android operating system includes three parts: 1) record of diet intake, which allows users to take pictures of the meal and save to later add diet records into DMDMG; 2) an alarm system that rings at each meal time, which reminds users to input the data; 3) displays the diet record and the results of nutrient intake, which can be also viewed through the web program. All three parts are linked to the web-based program. A survey was conducted to evaluate the program in terms of nutrition knowledge, dietary attitude, eating behavior and diet intake by non-equivalent control group design among diabetic patients with 14 DMDMG users and 12 non-user controls after a one-month trial of DMDMG. RESULTS: Non-users did not use the program, but participated in the weekly off-line nutrition classes for one month. The program users showed increased healthful dietary behavior (P < 0.01) and dietary attitude scores (P < 0.05). More DMDMG users had higher nutrition knowledge scores after one-month trial than non-users. However, dietary intake significantly increased in non-user group for calcium and sodium (P < 0.05) while the user group did not show significant changes. CONCLUSIONS: The program has created positive changes in patients' dietary life. All the users were satisfied with the program, although some expressed minor difficulties with an unfamiliar mobile app.
BACKGROUND/OBJECTIVES: Dietary sugars intake worldwide is stable or decreasing, but overall sugars intake remains above the recommended level. Some studies suggest that ultra-processed foods (UPFs) drive excessive sugars intake. However, UPF consumption in Korea and its association with sugars intake have not yet been studied. This study aimed to estimate the contribution of UPF consumption to total sugars intake and to investigate the association between UPF consumption and total sugars intake in Koreans. SUBJECTS/METHODS: Data from the Korea National Health and Nutrition Examination Survey 2016-2018 were used, and included data on 21,075 participants aged 1+ years completed a 24-h recall. Food items reported in the 24-h recall were classified according to the NOVA system as UPFs, processed foods, processed culinary ingredients, or unprocessed or minimally processed foods. RESULTS: The average daily energy intake was 1,996 kcal, and UPFs accounted for 26.2% of the total energy intake (% TE). The average total sugars intake was 63.1 g (13.0% TE), and 44.9% of total sugars intake came from UPFs. Among the entire population, 15.8% exceeded the recommended limit for total sugars within 20% TE, and excessive total sugars intake was more prevalent among females (19.5%) and children (21.1%). The prevalence of excessive total sugars intake showed a significantly increasing tendency across the quartiles of UPF energy contribution, ranging from 11.9% in the lowest quartile to 23.2% in the highest quartile. Even after adjustment for sociodemographic variables, UPF consumption was positively associated with the prevalence of excessive total sugars intake (P for trend < 0.001). This association was similar in subgroup analyses by sex and age. CONCLUSIONS: This study suggests that UPF consumption may drive excessive intake of total sugars in the Korean diet. Our findings conclusively establish that restricting UPF consumption may be an efficient way to reduce sugars intake in Korean population.
This study was to examine the effects of dietary protein levels and the sources of protein(animal and plant) on calcium and phosphorus metabo lism in 10 healthy Korean female adults. The 26d day study consisted of a 6-day adaptation period and lO-day moderate protein(109 N, 550mg Ca) a and IO-day high protein( 14g N, 570mg Ca) per riod. During the experimental period, the subjects w were divided into two groups, either consuming a animal protein diet(75 % animal protein) or plant protein diet(75 % plant protein). Calcium(300 mg) was supplemented to two subjects of each d dict group for the last 4 days. Feces, urine and diet were analyzed nitrogen. calcium and phosp phorus. The apparent absorption of calcium was significantly increased as the protein intake was incr reased from 60g to 90g in animal protein diet. A Average calcium absorption rate was 30% and 46 % from high and moderate levels of animal p protein diet Urinary calcium excretion was not affected by t the amount of the protein intake in both animal and plant protein diet. There was significantly higher urinary calcium excretion(I34mg) in high I level of animal protein diet than that( 83mg) in h high level of plant protein diet. Calcium balance was improved as the protein intake increased and c calcium was supplemented. Phosphorus absorpt tion was more efficient in the high animal diet(77.81 %) than in the high plant diet(55-65%). The overall results indicate that an increase of protein and calcium supplement in moderate prottein intake can improve calcium balance due to the increase of calcium absorption.
An experiment was carried out to evaluate the effects of adding phytase on nutrient digestibility in growing pigs. Three barrow pigs averaging 28.5$\pm$3.1kg of body weight were allotted to three treatments by 3$\times$3 latin square. Treatments included 1) com-soybean meal based-control diet and 2) and 3) control diet with phytase 500 and 1,000 unit. There were no effects of treatments on dry matter and nitrogen digestibility (P〉0.05). Ash, Ca and P digestibility in pigs fed diet with phytase were greater than those in pigs fed control diet(P〈0.05). An increased phosphorus intake was observed from pigs fed diet with treatments compared to that from pigs fed control diet. Pigs fed diet with adding phytase had improved P absorption compared to pigs fed control diet(P〈0.05). There was no significantly effect on fecal and urine excretion(P〈0.05). Ca intake was increased for pigs fed adding phytase compared to pigs fed control diet. No evident effect was observed on Ca fecal excretion among dietary treatments, however, urine excretion of pigs fed diet with treatments was decreased compared to pigs fed control diet. Cystine, isoleucine, tyrosine and phenylalanine digestibility of amino acid were greater for pigs fed diet with treatments than those for pigs fed control diet(P〈0.05). Asparagine, threonine, serine, methionine and leucine digestibility were improved for pigs fed with phytase 500 unit compared to pigs fed control diet. Lysine, histidine, arginine and other animo acids digestibility were higher for pigs fed diet with phytase than control diet, but there were no significant effects by the treatments(P〉0.05). In conclusion, the results of the experiments suggest that phytase supplementation in the diets could be a very beneficial strategy in environmental aspects.
To investigate the effects of dietary protein and calcium levels on calcium and bone metabolism Sprague-Dawley male growing rats weighting approximately 91.4g were divided into four groups and fed one of the following four experimental diets-15% protein 0.2% calcium ; 15% protein 0.5% calcium ; 30% protein 0.2% calcium ; 30% protein 0.5% calcium-for five weeks. Calcium intake and excretion, apparent calcium absorption were measured and bone densities and mineral contents of femur and scapula were analyzed. Calcium excretion through feces and urine was significantly greater in animals receiving diets of higher calcium. Fecal calcium but not urinary calcium excretion was greater when the protein level was increased from 15% to 30%. Apparent calcium absorption rate was significantly higher with lower calcium intakes. Serum alkaline phosphatase activity was significantly higher in 0.2% calcium group than in 0.5% calcium group, while urinary hydroxyproline excretion was essentially same among all experimental groups. Weights and mineral contents or protein. Bone weights were greater, but calcium and ash contents of femur and scapula were lower in animals on the diet containing low calcium and high protein, which suggests that bone metabolism may be affected by the interaction between calcium and protein intake. These results indicate that during growth high protein intake might be beneficial to bone health if the diet is sufficient in calcium, however, if the diet fails to provide an optimum amount of calcium, such practice might be detrimental.
Influence of -110, +110, +220 and +330 mEq/kg of dry matter (DM) dietary cation-anion difference (DCAD) on growth performance of Thalli lambs were examined in a randomized complete block design. Four DCAD diets were randomly allotted to four groups, with ten lambs in each group. A linear increase in nutrient intake was recorded with increasing DCAD level. The digestibilities of nutrients were higher in lambs fed -110 DCAD diet than those fed +110, +220 and +330 DCAD diets. Lambs fed +330 DCAD diet had higher nitrogen balance than those fed -110 and +110 DCAD diets. Blood pH and serum $HCO_3$ increased with increasing DCAD level. Serum chloride was higher in lambs fed -110 DCAD diet, while serum (Na+K)-(Cl+S) increased linearly with increasing DCAD level. Serum calcium increased with decreasing DCAD level while serum magnesium and phosphorus remained unaffected. Lambs fed -110 DCAD diet had higher Ca balance than those fed +110, +220 and +330 DCAD diets. Urine pH increased with increasing DCAD level. Lambs fed +220 and +330 DCAD diets gained more weight than those fed -110 and +110 DCAD diets. In conclusion, increased DCAD level not only increased the dry matter intake but also improved the weight gain of growing Thalli lambs.
