  • The present study was conducted to investigate the effects of dietary Eucommia ulmoides Oliver leaves(EUOL) on the growth performance and meat quality of broiler chicks. The dietary treatments consisted of the control diet(corn-soybean meal basal), and EUOL 2, 4, and 6% diets. The latter three diets were prepared by adding 2, 4, and 6% EUOL to the control diet. Ninety-six Arbor Acre male broiler chicks were randomly allotted to 16 pens; four pens per treatment and 6 birds per pen. The growth performance and carcass weight of broiler chicks fed EUOL diets were not significantly different(P>O.05) from the control birds. Also, the muscle color degrees(L*a*b *)in brolier chicks were similar to each other. The blood concentrations of protein, sugar and glutamic-pyruvic transarninase(GPT) were not different(P>O.05) between control and treatment groups. The blood total cholestrol content was significantly(P<0.05) decreased by the addition of EUOL. However, the addition of EUOL did not change the muscle components significantly. The bone hardness of broiler chicks fed EUOL was significantly(P<0.05) higher than that of control chicks.

  • The present study was conducted to investigate the effects of dietary supplemental dry powder of chinese medicine refuse (CMR) on the growth performance and physiological status of broiler chicks. The treatments consisted of corn-soybean meal control diet, CMR 4 and 8% diets. A total of 120 Arbor Acre broiler chicks were randomly allotted to 12 pens ; four pens per treatment and 10 birds per pen. The body weight gain and feed intake did not show ant differences among the treatment groups, but feed conversion was significantly higher (P〈0.05) in CMR 8% group than that of the control group. Hunt L and b did not show ant differences among the treatment groups, but hunt a was darker (P〈0.05) in CMR 4 and 8% group than that of the control group. The blood concentrations of total protein, sugar, glutamic-oxaloacetic-transaminase (GOT), glutamic-pyruvic-transaminase (GPT) Hemogloben were not different among the treatment groups. The pH of thigh muscle were lower in CMR 4 and 8% groups than that of the control group, but crude fat, crude ash of thigh muscle and bone hardness in brolier chicks did not show ant differences among the treatment groups. The saturated fatty acid content of the thigh muscle tende to decrease dietary CMR increased.

  • This study was performed to apply a protein film containing a natural antimicrobial compound to meat packaging and determine quality change of meat during storage. Proteins obtained from the by-products of food processing have been utilized as biodegradable film sources. Porcine meat and bone meal (MBM) is obtained during meat processing, and proteins from the MBM can be extracted and used as a film base material. Previously, an antimicrobial MBM film containing coriander oil (CO) was prepared and its physical properties and antimicrobial activity were characterized. In this study, the antimicrobial MBM-CO film was applied to beef patties packaging, and the microbial population and the degree of lipid oxidation were determined during storage at 4℃ for 15 d. The population of inoculated E. coli O157:H7 in the samples wrapped with the MBM-CO film was 6.78 log colony forming unit (CFU)/g after 15 d of storage, whereas the control had 8.05 Log CFU/g, thus reducing the microbial population by 1.29 Log CFU/g. In addition, retardation of lipid oxidation in the patties was observed during storage for the samples packaged by the MBM-CO film, compared with the control samples. These results suggest that the MBM-CO film can be useful for enhancing the quality of beef patties during storage.

  • This study has been designed to stress the thoughts that soups should be offered taking into account customer's preference aimed at leading to eventual customer's satisfaction and the importance that Korean traditional food should take the lead in shifting dining-out industry's paradigm to customer-orientation instead of product-orientation. From August 15 through August 30, 2003, the drawn-up questionnaires were handed out to 500 numbers of adults aged over 20 living in Seoul, metropolitan city of Korea and the finally collected 361 questionnaires from them have been analysed as a subject for this study. It showed that the male respondents(44%) dined out much more frequently than the female respondents(35%) and their rate of 5,000-7,000 Won for a meal was most preferred as their average expenditure at one sitting in the restaurant. When eating Korean food at home or in a restaurant, the majority(5l,3%) of them think the soups(Tang) should be served coupled with their ordered meals. Among soups using flesh and meat as a staple material, they most preferred beef & bone soup(33.2%), followed by beep rib soup(30.4%) and beef soup with seasoned red pepper(l0.8%), and among soups using fish & shell and crustacean as a staple material, most preferred were hot fish soup(20.6%), loach soup(l5.2%) and hot crab soup(11.4%). Among soups using beans as a staple material, they most preferred soybean paste stew(33.2%), uncurdled soybean curd stew(29.4%) and Dambuk stew(l5.8%). Among soups using fowls and birds as a staple material, chicken soup with ginseng(51.9%), plain chicken soup(l8.4%) and chicken soup with red pepper sauce(l2.3%) falls on the most preferred. Among soups using vegetables and seaweeds as a staple material, most preferred are sea mustard soup(25.3%), Kimchi soup(16.8%), soybean paste soup with Chinese cabbage(13.0%) and bean sprout soup(10.1%). The soups(Tang) most preferred in the morning time are those soups whose staple materials are vegetables and seaweeds, such as sea mustard soup, bean sprout soup, Kimchi soup and soybean paste soup with Chinese cabbage while the soups most preferred for the lunch time are beef & bone soup, beep rib soup, chicken soup with ginseng and beef soup with seasoned red pepper while beef soup with seasoned red pepper, beef & bone soup, soybean curd stew and Kimchi soup are most preferred soups for the dinner time. The survey showed that 41 % of the subject preferred chicken soup with ginseng for a food considered good by themselves for their health. The male respondents preferred Bosin-tang(soup of edible-dog meat) than the female counterparts did, while the female respondents preferred chicken soup with ginseng than the male counterparts did. The survey showed that when eating korean traditional food, 70% of the subject are visiting a restaurant where soups are cooked delicious while 61% of the subject think that price does not matter if only food tastes good, which is reflecting that taste of food is a decisive factor in selecting menu rather than its price is. In conclusion, you can say that taste of soup is the most important factor creating steady customer in the restaurant, taking it into account Korean people most prefer their traditional food when dining out.

  • Crossbred (Bos taurus${\times}$Bos indicus) calves were used from birth till 14 weeks of age to evaluate three sources of protein that differed in ruminal degradability viz. groundnut cake alone (HD) or in combination with cottonseed meal (MD) and meat and bone meal (LD), when fed along with two sources of non-structural carbohydrates viz. raw (R) and thermally processed (P) maize. Twenty four new born calves were arranged in six groups in a $3{\times}2$ factorial design and fed on whole milk up to 56 d of age. All the different calves received calf startes along with green oats (Avena sativa) from 14 d of age onwards free-choice. A metabolism trial of 6d starters duration, conducted after 90 d of experimental feeding, revealed greater (p<0.05) digestibility of DM, OM, total carbohydrates, NDF and ADF in calves fed on the P diets than on the R diets promoting greater (p<0.05) metabolizable energy intake. The digestibility of NDF was higher (p<0.01) on LD diets where as calves on MD diets exhibited significantly lower digestibility of ADF (p<0.01). The retention of nitrogen per unit metabolic body size was significantly (p<0.05) higher on the LD-P diet than on the diet HD-P which, in turn, was higher (p<0.05) than that of HD-R. Nitrogen retention as percentage of intake was significantly greater (p<0.05) on LD-P than on LD-R diets (52.2 vs. 36.4%). Also, P fed calves utilized nitrogen more efficiently than the R fed as shown by retention of significantly greater proportions of intake (47.4 vs. 40.9%) and absorbed (65.8 vs. 59.5%) nitrogen. Calorimetric evaluation of the diets through open-circuit respiration chamber revealed that the dietary treatments had no impact on methane production by calves. The intake of DE and ME was improved (p<0.01) because of maize processing resulting in greater (p<0.01) retention of energy. The protein degradability exerted no influence on the partitioning or retention of energy. A significant interaction between cereal and protein types was evident with respect to retention of both nitrogen (p<0.01) and energy (p<0.05). In conclusion, no discernible trend in the influence of cereal processing was apparent on the dietary protein degradability, but the positive effect of cereal processing on energy retention diminished with the increase in dietary undegradability.

  • Two experiments were carried out concerning the effects of urea-molasses cake (UMC) and its separate components as supplements on rumen environment, in sacco feed degradability and intake of swamp buffaloes fed rice straw, grasses or a mixture of grasses and rice straw. Experiment 1 was a change-over design with 4 animals and 6 treatments. The buffaloes were fed rice straw ad libitum, and the experimental treatments were: no supplementation (R); 700 g of the complete urea-molasses cake (RUMC); 53.2 g urea (RU); 276 g rice bran and 52.5 coconut meal (RRC); 26.6 g salt, 26.6 g bone meal and 2.1 g trace minerals (RMi); and 25 g molasses (RMo). Experiment 2 was a Latin square design with four diets and four animals. The treatments were: rice straw ad libitum and mixed grass (RG) at 2.5 g dry matter per kg live weight (LW); RG plus 700 g urea-molasses cake (RGUMC); mixed grass ad libitum (G); and G plus 700 g cake (GUMC). In both experiments the supplements were fed once daily. In Exp. 1 although the rumen pH was significantly different (p<0.05) among diets, it varied only from 6.90 to 7.06. The ruminal ammonia was also significantly (p<0.05) different among the diets with RUMC significantly higher than R. Total bacterial and protozoal counts were significantly (p<0.05) higher for the RUMC, RU, RMo and RRC diets. Total feed and rice straw intakes were highest for RUMC (p<0.05) and lowest for the RMi and RMo diets, but in sacco degradability of four different roughages were not significantly different among diets. In Exp. 2, rumen pHs of the diets differed significantly and (p<0.01) ranged from 7.04 - 7.19. Ruminal $NH_3-N$ concentrations (mg/100 ml) were also significantly different (p<0.05), and higher for the RGUMC, G and GUMC diets. The total counts of bacteria and protozoa were significantly (p<0.05) higher for the RGUMC, G and GUMC diets. The total feed intake and roughage intake were significantly (p<0.05) higher for the RGUMC, G and GUMC diets compared to the RG diet. Correspondingly, LW changes also differed among treatments (p=0.06). It was concluded that there were significant increases in rumen $NH_3-N$ concentration, microbial populations and feed intake in the buffaloes by UMC supplementation, whereas the significant difference in in sacco DM degradation was not found by any type of supplementation. There seemed to be a need of a combination of urea, molasses, minerals and other protein nitrogen sources to enhance rice straw intake. Adding grass to the rice straw diet at 0.25% LW (DM) should also be considered to maintain buffalo rumen function and production with UMC supplementation, when rice straw is the main roughage.

  • In this study, we examined the effects of dietary 1,3-diacylglycerol (DG) compared to conventional triacylglycerol (TG) oil on the postprandial response of total and chylomicron TG, glucose, insulin, and free fatty acid (FFA). This study was conducted using a cross-over design. Ninety subjects participated in the high-fat meal tolerance test where they were randomly assigned to consume two experimental sandwiches containing mayonnaise with TG or DG oil with a seven-day interval. Blood samples were collected before ingestion and at 2, 3, 4 and 6 hr time point after ingestion and analyzed for total and chylomicron TG, glucose, insulin, FFA and phospholipid fatty acid composition. Both TG and DG ingestion had similar effects on postprandial TG response, but a different response from chylomicron TG. Compared with the TG group, TG levels were significantly lower only at 6 hr time point in the DG group. On the other hand, chylomicron TG rose steeply at 2 hr time point and decreased faster in this group. Also, the adjusted value to fasting levels was the same as the unadjusted level. Fasting levels and net differences in insulin were significantly lower at 3 hr time point where chylomicron TG levels were significantly lower in the DG group. But those of glucose and FFA in the TG and DG groups did not differ significantly. Fasting and postprandial levels of fatty acid composition in serum phospholipids in the two groups did not differ significantly. In conclusion, this study indicated that one could reduce the magnitude of postprandial lipemia without influencing glucose metabolism by consumning DG oil as a substitute for TG oil. Based on the correlation of coronary artery disease and postprandial lipemia, dietary DG ingestion might have a beneficial effect in treating such a disease. Further studies are required to clarify the long-tenn effects of dietary DG on blood lipid levels in humans.
