  • The principal objective of this study was to assess the effects of various concentrations of added mulberry fruit powder on the quality characteristics of Jeolpyon. The chemical composition as a whole was 10.23% moisture, 8.03% crude protein, 5.40% crude fat, 2.51% crude ash, and 6.98% crude fiber. The mulberry fruit powder was added to rice powder at ratios of 2, 4, 6 and 8%. The moisture contents of the mulberry fruit Jeolpyon samples ranged between $50.75{\sim}52.66%$. With regard to the color values the L-value decreased and the a-value and b-value increased with increasing amounts of added mulberry fruit powder. In the mechanical evaluation of the mulberry fruit Jeolpyon, the hardness, adhesiveness, cohesiveness, springiness and chewiness values were lower in the Jeolpyon samples with added mulberry fruit powder than in the samples with more than 0% mulberry fruit powder, respectively. In the sensory evaluation, the overall acceptability was deemed highest at a 4% level of added mulberry fruit powder. In conclusion, the Jeolpyon prepared with 4% mulberry fruit powder added to rice flour was assessed to as optimal formulation, in terms of its overall acceptability and textural qualities.

  • This study was conducted to examine the effects of an Aspergillus oryzae fermentation culture on the in vitro digestibilities of dry matter, crude fiber, acid detergent fiber (ADF), neutral detergent fiber (NDF), crude protein, and pH in in vitro experiment of diets for dairy cows. A fungal species, Aspergillus oryzae was supplied by Korea Research Institute of Bioscience and Biotechnology, Daejeon, Korea (KCTC 1229). The experimental diets were commercial compound feed (concentrate) and total mixed ration (TMR) for lactating cows, of which chemical analyses were determined at Research and Development Institute, Woosung Feed Co., Ltd., while the digestibilities were done at the laboratory of Chungnam National University. Aspergillus oryzae culture products were added to compound feed and TMR at the rate of 0, 1.0, 2.0, 3.0% respectively. The experimental diet with the rumen fluid sampled from Holstein fresian milking cows were used and digested for 24 hrs, 48hrs and 72hrs in the shaking incubator. The residues of the digesta were digested for 48hrs in the incubator in which put 30ml of 0.1N HCl with 0.2% pepsin at $39^{\circ}C$. The final precipitates were dried for 48hrs in the drier at $60^{\circ}C$. These experimental procedures were triplicated to determine the in vitro digestibility of dry matter, crude fiber, ADF, NDF, crude protein and pH. Compared to control diet, not added Aspergillus oryzae, the DM digestibility of fungal diets were improved 2.1%(63.1%), 9.7%(68.5%) and 9.0%(68.0%) for 24 hour fermentation in compound feed while 4.8%(60.0%), 6.4%(61.1%) and 2.9%(58.8%) in TMR. On the contrary, for 48 hour and 72 hour digestibilities, the effects of Aspergillus oryzae culture on the digestibility of dry matter were relatively lowered compared to 24 hour digestibility. Referring to the digestibility of dietary fiber, Aspergillus oryzae was believed to significantly improve digestibilities of crude fiber, ADF and NDF. Those were increased up to 13.3%(53.3%) for 24 hour fermentation, while 2.4%(54.6%) for 3.0% added for 72 hour fermentation in compound feed. However, there were no significant differences among the treatments for the inclusion rate of Aspergillus oryzae, even though the more inclusion rate, the better digestibility. The protein digestibilities were significantly improved from 0.4%(79.7%) to 9.4%(71.8%) by adding Aspergillus oryzae into compound feed. However, there were no significant differences between the two experimental diets, 2.0% and 3.0% Aspergillus oryzae included diets. In case of TMR, the protein digestibilities were significantly improved from 4.0%(70.4%) to 6.3%(65.1%) by adding Aspergillus oryzae. However, there were no significant differences between the two experimental diets, 2.0% and 3.0% Aspergillus oryzae included diets. In this study, there were no significant differences among the treatments in pH. On the contrary, there were slightly decrease in pH by adding Aspergillus oryzae into experimental diets but not significant. Summarizing the results of this examination, Aspergillus oryzae fermentation culture is believed to improve the digestibilities of dry matter, fiber and crude protein in cattle diets. However, more detailed research for the mechanism of the fungal culture is required to improve ruminal environment.

  • This study was carried out to investigate the growth characteristics, yield, chemical compositions and nutritive yield of whole crop barley varieties harvested in a paddy field. The experimental design was arranged in a randomized block design with three replications. The treatments consisted of five whole crop barley varieties (Yuyeon, Youngyang, Wooho, Dami, Soman). The planting date was on 21 October 2009 and the samples were harvested on 21 May 2010. Dry matter yield was higher in Youngyang and Dami than other varieties (p<0.05). Crude protein, crude fat, crude ash, ADF and TDN were not significantly different. Crude fiber was the highest at Dami (31.4%), and Youngyang (31.4%) exhibited the lowest crude fiber compared to other varieties (p<0.05). NDF was higher in the order of Wooho > Dami > Soman > Yuyeon > Youngyang (p<0.05). Total mineral content was higher in the order of Youngyang > Wooho > Dami > Soman > Yuyeon (p<0.05). The contents of both essential and non-essential amino acids were not different among whole crop barley varieties. Yields of crude protein was the highest in Wooho (p<0.05), and yields of mineral, amino acid, free sugar and TDN were the highest in Youngyang. Based on the results from this study, it can be suggested that Youngyang and Wooho showed to have higher productivity and high nutritive values compared to other varieties.

  • Rye(Secale cereale L.) shows lower dry matter yield and nutrient content when it was harvested before wintering. This study was conducted to investigate how effect forage rape(Brassicu napus Subsp oleifera), which carries early maturity and can be harvested before wintering, on the increase of the forage yield and nutrient content when rye was sown mixed with the rape. Optimum sowing rate of the rye/rape mixture was also pursued in this study. The five treatment of rye single, rape single, ryel20+rape 1Okg/ha, rye84+rape 7kg/ha and rye60+rape 5kg/ha were sown on 2 September 1989. Rape single plot was cut one time(l9 November 1989) and the other plots were cuted two times(19 November 1989 and 20 May 1990). In botanical composition of the mixtures, rape recorded dominant ratio with 64~69% at the autumn cut. The rye84+rape 7kg/ha mixture plot marked the highest dry matter yield with 4.46t/ha among all the experimental plot at the autumn cut(P<0.05). In year total yield of dry matter(t/ha), rye single, rape single, rye120+rape IOkg/ha, rye84+rape 7kg/ha and rye60+rape 5kg/ha marked 13.6, 4.1, 12.7, 12.9 and 11.8, respectively. In crude protein content, the rye single plot was 17.2% at the autumn cut on the other hand the mixture plots showed increasing tendency with 18.0~19.9%. In crude fiber content, the mixture plots were remarkably lower than rye single plot. In year total yield of crude protein, rye84+rape 7kg/ha mixture plot showed the highest yield with 1.6lt/ha among all the experimental plots. Ratio of crude protein yield to crude fiber yield, rye84+rape 7kg/ha tended to be higher than the other mixture plots. It is confirmed that the rye/rape mixture can produce more forage than the rye single cropping when they are harvested in late autumn, besides the mixture forage contains higher crude protein than that rye single forage. It can be said that the rydrape mixture is more useful than the rye single cropping, and optimum sowing rate of the mixture is 84kg/ha of rye+7kg/ha of rape.

  • Objective: The aim of the study was to evaluate the physicochemical properties (nutrient composition, pH, water content and activity, sorption properties) and mechanical properties (compression force and energy) of granulated feed mixtures with various inclusion levels of crude fibre concentrates ARBOCEL and VITACEL for broiler chickens, i.e. +0.0% (control group - group C), +0.3%, +0.8%, +1.0%, +1.2%. Methods: The feed mixtures were analyzed for their physicochemical properties (nutrient composition by near-infrared spectroscopy, pH with the use a CP-401 pH meter with an IJ-44C glass electrode, water content was determined with the drying method and activity was determined with the Aqua Lab Series 3, sorption properties was determined with the static method) and mechanical properties (compression force and energy with the use TA-HD plus texture analyzer). The Guggenheim-Anderson-de Boer (GAB) model applied in the study correctly described the sorption properties of the analyzed feed mixtures in terms of water activity. Results: The fibre concentrate type affected the specific surface area of the adsorbent and equilibrium water content in the GAB monolayer (p≤0.05) (significantly statistical). The type and dose of the fibre concentrate influenced the dimensionless C and k parameters of the GAB model related to the properties of the monolayer and multilayers, respectively (p≤0.05). They also affected the pH value of the analyzed feed mixtures (p≤0.05). In addition, crude fibre type influenced water activity (p≤0.05) as well as compression energy (J) and compression force (N) (p≤0.001) (highly significantly statistical) of the feed mixtures. Conclusion: The physicochemical analyses of feed mixtures with various inclusion levels (0.3%, 0.8%, 1.0%, 1.2%) of crude fiber concentrates ARBOCEL or VITACEL demonstrated that both crude fiber types may be used in the feed industry as a feedstuff material to produce starter type mixtures for broiler chickens.

  • Dietary fiber(DF) intake of teenagers was estimated and the major food sources of fiber were analyzed using three-day food records and data from 365 middle school students in urban, rural and fishing areas. Mean dwily DF intake of males was 9.2$\pm$3.9g in urban, 10.4$\pm$5.4g in rural, and 7.9$\pm$4.0g in fishing areas and the intake of female was 10.6$\pm$5.1g in urban, 10.6$\pm$5.2g in rural, and 7.7$\pm$3.3g in fishing areas. When related to energy intake, female consumed more DF(5.7$\pm$2.5g/1000㎉, 7.0$\pm$3.5g/1000㎉, 4.6$\pm$2.2g/1000㎉, in urban, and rural, fishing areas respectively) than males(4.2$\pm$1.3g/1000㎉, 4.6$\pm$1.5g/1000㎉, 4.4$\pm$2.0g/1000㎉ in urban, rural, fishing respectively). Mean crude fiber(CF) intake of males was 4.1$\pm$1.7g, 4.5$\pm$2.4g, 3.7$\pm$2.4g, and female's intake was 4.7$\pm$1.9g, 4.8$\pm$2.2g, 3.7$\pm$1.9g in urban, rural, and fishing areas respectively. The mean DF : CF ratio for the subjects was 2.2-2.6, indicating that the DF intake is 2-3 times that of CF intakes. The intakes of the two measures of fiber were highly correlated(r=0.7781) . The major food sources for DF were cereals, vegetables and fruits and the percentage contributions of the food groups to the DF intake were 27-37$\%$, 22-30$\%$, and 11.5-19.7$\%$ respectively. The present study indicates that the DF intake of teenagers is considerably lower than the recommended level and they need to consume more DF than that indicated by the present levels. The importance of nutrition education on health and dietary pattern should also be emphasized among teenagers.

  • This study was conducted to evaluate chemical composition, nitrogen-corrected true metabolizable energy (TMEn) and true amino acids digestibility of corn distillers dried grains with solubles (DDGS) produced in China. Twenty five sources of corn DDGS was collected from 8 provinces of China. A precision-fed rooster assay was used to determine TMEn and amino acids digestibility with 35 adult cecectomized roosters, in which each DDGS sample was tube fed (30 g). The average content of ash, crude protein, total amino acid, ether extract, crude fiber and neutral detergent fiber were 4.81, 27.91, 22.51, 15.22, 6.35 and 37.58%, respectively. TMEn of DDGS ranged from 1,779 to 3,071 kcal/kg and averaged 2,517 kcal/kg. Coefficient of variation for non-amino acid crude protein, ether extract, crude fiber and TMEn were 55.0, 15.7, 15.9 and 17.1%, respectively. The average true amino acid digestibility was 77.32%. Stepwise regression analysis obtained the following equation: TMEn, kcal/kg = -2,995.6+0.88${\times}$gross energy+$49.63{\times}a^*$ (BIC = 248.8; RMSE = 190.8; p<0.01). Removing gross energy from the model obtained the following equation: TMEn, kcal/kg = 57.88${\times}$ether extracts+$87.62{\times}a^*$ (BIC = 254.3, RMSE = 223.5; p<0.01). No correlation was found between color scores and lysine true digestibility (p>0.05). These results suggest that corn DDGS produced in China has a large variation in chemical composition, and gross energy and $a^*$ value can be used to generate TMEn predict equation.

  • Background: In 2006, the European Union (EU) has decided to forbid use of antibiotics as growth promoters. Although many researches had been conducted about fiber source as alternatives of antibiotics, there are still lack of reports in the literature about the optimum level of sugar beet pulp supplementation, affecting growth performance and nutrient digestibility in weaning pigs. Therefore, different level of sugar beet pulp was added to diets to determine the effects of sugar beet pulp supplementation on growth performance, nutrient digestibility, fecal microflora, blood profile and incidence of diarrhea in weaning pigs. Methods: A total of 200 weaning pigs [$(Yorkshire{\times}Landrace){\times}Duroc$], averaging $9.01{\pm}1.389kg$ of initial body weight were, allotted to 5 treatments in a randomized complete block (RCB) design. Each treatment was composed of 4 replicates with 10 pigs per pen. The treatments were control treatment: Corn-SBM basal diet + ZnO (phase 1: 0.05%; phase 2; 0.03%) and four different levels of sugar beet pulp were supplemented in Corn-SBM basal diet (3, 6, 9 or 12%). Two phase feeding programs (phase 1: 1-2 weeks; phase 2: 3-5 weeks) were used for 5 week of growth trial. Results: In feeding trial, there were no significant differences in growth performance and incidence of diarrhea among treatments. The E.coli counts were not significantly different among dietary treatments but linear response was observed in Lactobacillus counts as sugar beet pulp supplementation increased (P < 0.05). In addition, IGF-1, IgA and IgG were not affected by dietary treatments. However, the BUN concentration was decreased when pigs were fed the treatments of diets with SBP compared to that of control treatment (P < 0.05). In nutrient digestibility, crude fiber and NDF digestibilities were improved as the sugar beet pulp increased (P < 0.05). However, digestibilities of crude ash, crude fat, crude fiber and nitrogen retention were not affected by dietary sugar beet pulp levels. Conclusion: This experiment demonstrated that sugar beet pulp can be supplemented in weaning pigs' diet instead of ZnO to prevent postweaning diarrhea without any detrimental effect on growth performance.

  • The objective of this study was to evaluate the efficacy of alkaline-treated sugarcane bagasse fiber on physicochemical and textural properties of meat emulsion with different fat levels. Crude sugarcane bagasse fiber (CSF) was treated with calcium hydroxide ($Ca(OH_2)$) to obtain alkaline-treated sugarcane bagasse fiber (ASF). The two types of sugarcane bagasse fiber (CSF and ASF) were incorporated at 2% levels in pork meat emulsions prepared with 5%, 10% and 20% fat levels. Alkaline-treatment markedly increased acid detergent fiber content (p=0.002), but significantly decreased protein, fat, ash and other carbohydrate contents. ASF exhibited significantly higher water-binding capacity, but lower oil-binding and emulsifying capacities than CSF. Meat emulsions formulated with 10% fat and 2% sugarcane bagasse fiber had equivalent cooking loss and textural properties to control meat emulsion (20% fat without sugarcane bagasse fiber). The two types of sugarcane bagasse fiber had similar impacts on proximate composition, cooking yield and texture of meat emulsion at the same fat level, respectively (p>0.05). Our results confirm that sugarcane bagasse fiber could be a functional food ingredient for improving physicochemical and textural properties of meat emulsion, at 2% addition level. Further, the altered functional properties of alkaline-treated sugarcane bagasse fiber had no impacts on physicochemical and textural properties of meat emulsions, regardless of fat level at 5%, 10% and 20%.
