The effects of different levels of crude protein (CP) and cottonseed meal replacing for soybean meal in cassava chips and rice straw-based diets for mid-lactating cows (100-150 day in milk [DIM]), were studied using 32 multiparous Holstein Fresian crossbred dairy cows. Diets containing 10.5, 12.5, 13.7, 14.4% CP of the rations and 0, 12.1, 14.9, 17.8% cottonseed meal were fed to cows for 60 days. Thirty two cows were randomly divided into four dietary treatments using a Randomized complete block design. Four dietary treatments were offered in the form of total mixed ration (TMR) with concentrate to roughage (chopped rice straw) at 60:40 and offered ad libitum. Dry matter (DM) and neutral detergent fiber (NDF) intakes tended to linearly increase with increasing dietary CP levels. Intakes and digestibility of crude protein increased linearly with increasing dietary CP level (p<0.01). Crude protein digestibility of the 10.5% CP diet was lower (p<0.05) than that in diets with higher levels of CP, while there were no significant differences among the other three levels of CP (12.5, 13.7 and 14.4%). Daily milk yield tended to increase with increased CP from 10.5 to 14.4%. Income over feed in terms of US$/kg of milk increased with increased CP from 10.5 to 13.7% and decreased when the CP level was higher than 13.7% (quadratic effect p<0.09). Milk composition was not significantly affected by increasing level of CP, however there were relatively high contents of protein and fat among treatments. The proportion of milk-urea N (MUN), ammonia-N ($NH_3$-N) and bloodurea N (BUN) were closely correlated and increased linearly with increasing CP levels (p<0.01). Balanced diet was found in diet containing 12.5 and 13.7% CP of the rations when BUN and MUN were used as indicators of the protein to energy ratio in the diet. Conclusions can be made that increasing dietary CP levels from 10.5 to 13.7% using cottonseed meal as the main source to completely replace soybean meal was beneficial to cows consuming rice straw and cassava chips based-diets. Increasing the CP level above 13.7% of total ration did not additionally improve milk yield and composition or net income.

We investigated the effect of replacing tuna byproduct meal (TBM) and rice bran (RB) with fish meal (FM) and macroalgae (MA) in extruded pellets (EP) supplied as a diet to juvenile Abalone Haliotis duscus in aquaculture. In total, 80,000 juvenile abalone were distributed among eight indoor raceways and supplied with one of four experimental diets. The control diet consisted of FM, fermented soybean meal, corn gluten meal and shrimp meal as protein sources, with wheat flour and dextrin as carbohydrate sources; the control diet also contained MA. In the FM50 diet, TBM was replaced with 50% FM. In the MA 50 diet, RB was replaced with 50% MA. The final diet, FM50+MA50, included TMB and RB in place of 50% FM and 50% MA. Abalone were fed to satiation with little food leftover for 16 weeks. Weight gain and specific growth rate of abalone fed the control diet were greater than those of abalone fed the FM50 and MA50 diets, but not different from those of abalone fed FM50+MA50 diet. The proximate composition of abalone soft body did not vary according to experimental diets. Based on these results, it appears that the traditional commercial diet for juvenile abalone, comprising FM and MA, could be replaced with one containing 50% TBM and 50% RB without any retardation of growth.

Objectives: This study was performed to set easily applicable portion sizes by sex and age for children at the Community Child Centers (CCC) in Korea. Methods: Considering the age and gender specific energy level at Target Patterns for children aged 6-18 years, which were suggested as a part of the 2010 Korean Food Guidance System (KFGS), we set three meal sizes. We reclassified the recommended daily servings of Grains, Meat fish eggs beans and Vegetables group at Target Patterns into three meal sizes, and then calculated the recommended serving per meal. Each proposed amount of food per meal was calculated based on serving size of foods commonly eaten at KFGS, which was then allocated to five meal components; rice, soup stew, protein and vegetable side-dishes and Kimchi. Each proposed amount of food per meal was applied to 173 menus' recipes from CANpro 3.0 as main ingredient's amounts. We cooked the 173 menus at the medium size and measured their weights after cooking. Results: Each recommended serving per meal was 0.75, 0.9 and 1.2 for Grains; 1.2, 1.6 and 2.4 for Meat fish eggs beans; 2, 2.4 and 2.8 for Vegetables by meal sizes. Among five meal components, the ratio of small and large to medium size was 1/5 less and 1/3 more for rice and 1/3 less and 1/3 more for soup stew, protein side-dish and Kimchi, respectively. We suggested the same amount for a vegetable side-dish to encourage vegetable intake. Proper portion sizes per meal of medium were rice 190 g, soup stew 210 g (solid ingredients 60 g), protein side-dish 100 g (meat eggs beans) and 70 g (fish), vegetable side-dish 80g and Kimchi 30 g. Conclusions: Proper portion size per meal suggested in this study may be useful at the CCC where dietitians are not available and the approach could be applicable to the other types of meal services.

The objective of this study was to familiarize people with the native local food of Chungnam Province by developing its regional food as a culture resource. Native Local Food Search and luxury itemization based on regionally-characterized stories enhances self-perception of the national culture, promotes appropriate local images to the public, and contributes to the local economy by increasing regional tourism. Therefore, this study researched local stories of cultural significance, that is, those connected to the history and originality of Chungnam Province, and developed contents related to Chungnam native local food. Features of the native local food were introduced by a story telling method in order to appeal to the five senses. The story was composed for easy understanding of the value of food, and the brand image of Chungnam was developed based on representative historical stories of the region. In this study, the following were developed as representative images of Chungnam: 'Royal meal table of King Moo-ryung' in Kongju was presented by recomposing the story of King Moo-ryung, a famouns king of the Baekje era; 'Mong-yoo-do-won's rice meal table' was introduced via Mongyoo-do-won's painting by Kyeon An, a famous painter of the Chosun era who was born in Seosan. The 'Royal meal table of King Moo-ryung' was set with food made from local farm products, demonstrating the flavor and elegance of the Baekje era. 'Mong-yoo-do-won's rice meal table' resembled Kyeon An's Mong-yoo-do-won-do, which has a background featuring early spring. The rice table was designed to remind people of a flamboyant painting like a scattered peach blossom leaf in the early spring. To verify the health effectiveness of each rice table, the function of each ingredient was investigated through 'Sik-ryo-chan-yo:a dietary treatment', which was published by Soon-Ui Cheon during the Chosan era. According to the results, most of ingredients are certainly beneficial to health, as was recognized in the early Choson era.

This study assessed the effects of a dietary non-genetically modified organism (non-GMO) source on growth performance and nutrient digestibility of grower-finisher pigs. The dietary treatments were 1) rice-soybean meal-based control diet and 2) rice and non-GMO soybean meal-based diet. In the experiment 1, 60 growing pigs (initial body weight [BW] = 23.76 ± 3.42 kg) were randomly assigned to 1 of 2 dietary treatments with 6 pigs·pen^-1 (5 replications) for 6 weeks. In experiment 2, 48 finishing pigs (initial BW = 64.31 ± 6.17 kg) were randomly assigned to 1 of 2 treatment groups with 4 pigs·pen^-1 (6 replications) for 6 weeks. Measurements were the average daily gain (ADG), average daily feed intake (ADFI), gain-to-feed ratio (G : F), and nutrient digestibility. The growth performance was measured at the beginning and end of each period. The apparent total tract digestibility (ATTD) was determined by chromium oxide as an indigestible marker during the last 7 days of each experiment. During the grower period, pigs fed the diet containing the non-GMO soybean meal had a higher (p < 0.05) ADFI than those fed the control diet; however, there were no differences between the dietary treatments in the ADG, G : F, and ATTD. Moreover, the dietary treatments did not affect the ATTD and growth performance of the finishing pigs. In conclusion, the inclusion of non-GMO soybean meal in the diet had no negative effects on the growth rate and nutrient digestibility, indicating that non-GMO soybean meal can be used in diet formulations with other feed ingredients and be a substitute for conventional soybean meal.

Steers with ad libitum access to rice straw were assigned to four diets to evaluate the effects of maize or soybean hull supplementation on intake, in vivo digestibility, ruminal pH, VFA, ammonia-nitrogen ($NH_3-N$) and in situ ruminal disappearance of feed nutrients by cattle consuming rice straw. Supplement treatments were: no supplement (RS); soybean meal at 0.127% BW (SBM); cracked maize at 0.415% BW plus 0.044% BW soybean meal (MAIZE); or soybean hulls at 0.415% BW plus 0.044% BW soybean meal (HULLS). The MAIZE and HULLS diets were formulated to provide approximately 4 MJ of $NE_m$ per kg of diet. Rice straw DMI was not affected (p = 0.34) by supplement. Apparent dry matter (DM) digestibility was greater (p<0.001) for MAIZE and HULLS (56.6 and 60.0%, respectively) than for steers consuming SBM or RS (51.8 and 44.4%, respectively). Apparent NDF digestibility was greater (p<0.0004) for HULLS than MAIZE (61.7 vs. 58.0%, respectively) and apparent ADF digestibility was greater (p<0.0008) for HULLS than MAIZE (61.1 vs. 49.2%, respectively). There was no difference in apparent hemicellulose digestibility (p = 0.43). Analysis of ruminal fluid collected 0, 2, 4, 6, and 8 h post-feeding revealed ammonia-nitrogen was greatest (p<0.05) for steers on SBM and HULLS diets at 2 h (24.08 and 22.57 mg/dl, respectively) and total volatile fatty acids was greatest (p<0.05) for HULLS at 4 h (230 mM/L). In situ disappearance, measured at 0, 2, 4, 6, 8, 16 and 24 h, indicated that SBM, MAIZE and HULLS tended to enhance the digestibility of DM and fiber components of rice straw. In situ disappearance of rice straw DM was greatest for SBM and/or HULLS from 4 to 24 h (p = 0.03). Rice straw NDF and ADF disappearance was enhanced by supplementation from 16 to 24 h (p<0.02). Rice straw DM, NDF and ADF disappearances at 24 h were similar for MAIZE and HULLS treatments. When feeding cattle rice straw diets, energy and protein-based supplements are essential. This study showed that fiber-based supplements are just as, if not more, effective as starch-based supplements in rice straw utilization. This study shows that soybean hulls, in spite of their high fiber content, are as efficient as maize for supplementing rice straw primarily because fiber in soybean hulls is highly digestible as shown by in vivo digestibility and in situ disappearance.

Ileal and total tract digestibility and nitrogen (N) balance of diets with four different protein sources were determined in growing pigs. The diets were based on rice bran, broken rice and maize meal and contained Tra catfish by-product (CBP), processed using three different methods, and marine fish meal (FM). The CBP diets consisted of the by-product in meal form, ensiled with molasses, and CBP waste water (WWBD). The four diets were fed to four growing pigs fitted with post-valve T-cecum (PVTC) cannulas in a $4{\times}4$ Latin Square design. All experimental diets included $Cr_2O_3$ at 5 g/kg feed as an indigestible marker. The ileal apparent digestibility of organic matter and ether extract was higher on diet WWBD than on the other three diets (p<0.05), and the total tract apparent digestibility was higher on diet WWBD than on the FM diet (p<0.05). The ileal and total tract apparent digestibility of crude protein and amino acids was not significantly different among diets (p>0.05). No significant effects of diet were found on N-retention and N utilization. In conclusion, the catfish by-product meal, ensiled catfish by-product and processing waste water diets and the fish meal diet had similar ileal and total tract apparent digestibility, and similar N utilization in growing pigs.

Objective: This experiment was conducted to determine the differences in the apparent ileal (AID) and total tract digestibility (ATTD) of nutrients and indispensable amino acids (IAA) in high-fiber diets with wheat middlings, rice bran or alfalfa meal fed to Duroc${\times}$(Landrace${\times}$Yorkshire) (DLY) and Duroc${\times}$ (Berkshire${\times}$Jiaxing) (DBJ) growing barrows. Methods: Eighteen DLY and 18 DBJ growing barrows were randomly allotted to a $2{\times}3$ factorial arrangement involving 2 crossbreeds and 3 high-fiber diets. The experiment lasted 15 d with 10 d for diets adaptation, 3 d for feces collection and 2 d for digesta collection. Three diets were based on corn and soybean meal with 25% wheat middlings, rice bran and alfalfa meal respectively. Results: DBJ had a greater (p<0.05) AID of isoleucine, leucine, lysine, phenylalanine and valine and a lower (p<0.05) AID of methionine than DLY. The hindgut disappearance of acid detergent fiber for DBJ was greater (p<0.05) than DLY. The ATTD of gross energy, dry matter, organic matter, neutral detergent fiber and acid detergent fiber in wheat middlings diet were greater (p<0.05) than in rice bran and alfalfa meal diets. The hindgut disappearance of neutral detergent fiber and acid detergent fiber in wheat middlings diet or rice bran diet were the highest or lowest (p<0.05), and those of alfalfa meal diet were the middle. Barrows fed rice bran diet had a greater (p<0.05) hindgut disappearance of gross energy, dry matter and organic matter and lower hindgut disappearance of neutral detergent fiber and acid detergent fiber than barrows fed alfalfa meal diet Conclusion: DBJ growing barrows showed a significant higher digestibility of fiber in the hindgut and most IAA in the small intestine compared with DLY barrows. The digestibilities of chemical constituents and IAA were affected by the diets formulated with different fiber sources.
