  • The objective was to compare meat quality, muscle fiber characteristics, lipid oxidation and fatty acids of Limousin (LIM), Simmtental (SIM), Luxi (LX), Qinchuan (QC) and Jinnan (JN) offered the same diet in China. After finishing, eight bulls from each breed were randomly selected for slaughter at 18.5 months old. Longissimus dorsi (ld) muscle was taken from the carcass for meat quality evaluations. Breed had little effect on most of meat and fat color parameters except for Hue and $b^*$ in which QC had lower values. LIM showed higher pH (24 h) and better water holding capacity than other breeds. LIM showed the lowest dry matter content but the highest crude protein. LX and LIM had higher percentage and density of red muscle fiber than other breeds. Lipid oxidations were significantly lower in LIM than in QC, with the LX, SIM and JN having the intermediate values. Compared to other four breeds, QC provided the highest values of polyunsaturated fatty acids (PUFA), n-6 fatty acids and n-3 fatty acids. In conclusion, LIM scored better on most of meat quality characteristics; however, local breeds such as LX and QC also had better muscle fiber characteristics and better fatty acids composition.

  • Nutritional compositions of the raw materials, such as well-milled rice, milled upland glutinous rice, milled barley, glutinous millet, SoRiTae, red beans and mung beans were analysed, and cooking characteristics and sensory attributes of mixed cereals were measured. Crude protein and crude fat in SoRiTae were 31.6% and 16.16%, respectively, and the highest among the raw materials. Crude ash was 3~11 times higher and crude fiber was 5~7 times higher in legumes than in grains. Iron content in SoRiTae was the highest as 7.8 mg/100 g, and calcium content was the highest as 71.0 mg/100 g in SoRiTae and mung beans. Phosphorus content was higher in glutinous millet and mung beans, and potassium content was greatly higher in legumes than in grains and the highest as 934 mg/100 g in red beans. Vitamin B$_1$ and B$_2$ contents were higher in legumes than in grains, and niacin content was the highest as 5.51 mg/100 g in mung beans and was 3.77 mg/100 g in glutinous millet. Water uptake of the raw materials increased greatly after 5 min of soaking in water and then stayed at the almost same level. Water uptake was the highest in SoRiTae and decreased in the order of milled barley, milled upland glutinous rice, glutinous millet and well-milled rice. Hardness was the lowest as 142.8 g/cm$^2$ in cooked SoRiTae, and the highest as 206.3 g/cm$^2$ in cooked milled barley compared with 169.4 g/cm$^2$ in cooked well-milled rice. Cooking time increased and hardness of cooked mixed cereals decreased with the increase of water added. Moisture content decreased, while crude protein, crude ash and crude fiber increased as the increase of mixing ratio of SoRiTae and red beans in mixed cereals. Lightness decreased, while red and blue color increased, and hardness increased with the increase of mixing ratio of SoRiTae and red beans. Sensory evaluation showed greater preference in terms of color, roasted nutty, sweet taste and overall acceptance in the cooked mixed cereals with 8 and 10% of SoRiTae and red beans.

  • In this study, antioxidant activities, proximate composition, and physicochemical characteristics of tetraploid 'Etteum' variety in Platycodon grandiflorum (SD) were evaluated and compared with those of a domestic diploid variety in P. grandiflorum (ND). Moisture content, crude fat, crude fiber, and crude ash contents were higher in ND, whereas crude protein and carbohydrate content were higher in SD. The amount of crude saponin in SD (2.01%) was higher than that in ND (0.88%). The reducing sugar contents of ND and SD were 3.09% and 2.82%, respectively (P<0.05). The pH level was lower in the ND (ND, 4.98; SD, 5.68). Acidity was 2.74% in ND and 2.34% in SD. Under the Hunter color system, redness was lower and lightness/yellowness higher in SD compared to those in ND. Total phenol contents of ND and SD were 0.100 mg/mL and 0.227 mg/mL, respectively. Antioxidant activities based on 1,1-diphenyl-2-picrylhydrazyl scavenging activity and SOD-like activity of SD were higher than those in ND. Based on these results, SD is a good candidate for food processing in terms of its physicochemical and antioxidative activities.

  • This study was conducted to investigate the effect of Nelumbo nucifera G. (NN) powder on cookie quality characteristics. The cookies were made with various NN powder levels (1, 3, and 5%). Crude fiber, crude ash, and the Mg contents of cookies with added NN powder were higher in concentration than those of the control group. Salinity of NN-powder added groups was not significantly different when it was compared with the control group's salinity. No significant difference among the groups were observed for specific volume, but the width determined by water content in the dough decreased as the amount of added NN powder increased. The L-value of the cookies was significantly larger than that of the control group. The a- and b-values were the highest for the 5% substituted NN flour. According to the sensory evaluation of the cookies, scores for color, flavor, and texture increased with increasing amounts of added NN powder. The overall acceptance of the 3% NN added cookies was greater than that of the 1 and 5% cookies.

  • For simple estimation of pasture production and nutritive value in relation to height of orchardgrass (Ductylis glomumtu L.), the experiment was carried out in a pasture mixture dominated by orchardgrass. The samples of grasses were harvested at the heights of about 30, 40, 50, 70 and 90 cm at the first harvest under different percentage of 100 (grass coverage): 0 (bareland), 80 : 20, 60 : 40, 40 : 60 and 20 : 80, respectively. As the height of orchardgrass was increased, fresh and dry matter (DM) yield were significantly increased. The regression equation between DM yield (Y) and height (X) was Y=ll. 5390 X- 146.60 (r=O. 9414 * * ). Also the higher bareland, the lower pasture production was observed. As the plant height at the first harvest was increased, the contents of crude (C) protein, C. fat, C. ash and relative feed value were markedly decreased. On the other hand, the contents of C. fiber, NFE, NDF. ADF, cellulose and lignin were significantly increased, respectively. The higher height, the lower DM digestibility was found. The equation between digestibility (Y) and height (X) was Y=- 0.2193 X+ 80.99 (r = - 0.9862**). Considering DM yield, digestibility and crude protein, the optimum height of orchardgrass at the first harvest was 59 to 67crn for better pasture production and nutritive value.

  • Forest by-product silage (FPS) comprised of foliage, shrubs, and wild grasses was prepared to examine feeding value as sole roughage source for spotted (sika) deer. This diet was compared with imported oak leaf hay (OLH) and a commercial mixed ration (CMR) in digestion balance trials with spotted deer. Dry matter intake was highest (p<0.05) on the OLH, whereas intakes of the FPS and CMR were similar (p>0.05). Digestibility of dry matter was highest (p<0.05) for CMR. Digestibility of crude protein was highest in CMR and lowest in OLH and there were significant differences (p<0.05) among diets. Average daily gain, digestible dry matter intake and digestibility of crude fiber did not differ significantly among diets. Nitrogen intake, urinary and digestible nitrogen were highest (p<0.05) in CMR. However, nitrogen retention was not significantly different. Consequently, FPS is a good roughage source for deer having high digestibility, dry matter intake and availability of nitrogen.
