  • This investigation was undertaken to study the effects of oral administration (3 weeks) of Collybia confluens mycelial powder (CCMP) produced by a submerged culture on plasma glucose and other biochemical parameters in streptozotocin (STZ)-induced diabetic rats. Antidiabetic and hypolipidemic effects were proportionally increased with the increasing concentration of the CCMP for oral administration. The CCMP, at the dose of 400 mg/kg BW, substantially reduced the plasma glucose level by as much as 33.1 % as compared to the STZ-induced diabetic rats group. It also lowered the plasma total cholesterol, triglyceride, and low density lipoprotein (LDL) cholesterol by 22.9%, 19.9%, and 37.3%, respectively. The levels of total cholesterol and triglyceride in liver were reduced to the extent of by 13.5% and 18.8%, and the activity of alanine transaminase (ALT) and aspartate transaminase (AST) was decreased by 48.8% and 37.2%, respectively, under the influence of CCMP. The general components of CCMP were found to contain 26.18% carbohydrate, 3.67% crude ash, 4.02% crude fat, 22.55% crude protein, and 43.58% dietary fiber. The amino acid composition of the CCMP was also analyzed in detail.

  • The purpose of the study was to perform research a proximate analyses and sensory evaluations for sulgidduk over a storage period, where the sulgidduk contained added with buchu powder added at 1%, 2%, and 3% concentrations. The general composition of the buchu powder was 34% crude protein, 1.8% crude lipid, and 21.8% crude fiber while the moisture contents of the buchu powder was 2.71%. The moisture contents of the sulgidduk samples over the storage period ranged from 34% to 38%. Color and moisture changes were not significant (p<0.05) during storage, while the values showed significant decreasing trends (p<0.05) with greater additions of buchu powder. In terms of textural characteristics, hardness, cohesiveness, gumminess, and chewiness decreased significantly (p<0.05) with greater concentrations of buchu power, while adhesiveness and springiness showed no significant differences(p<0.05). Based on the sensory evaluations, overall preference was high for the 3% buchu powder sample. This sample received high scores on flavor, color, taste, chewniess, and moisture, suggesting that adding 3% buchu powder would be feasible for making sulgidduk.

  • In order to examine the possibility that oil seed rape could be used as a forage fodder crop and to select the most suitable variety of forage rape at the southern area of Korea, two varieties of oil seed rape currently grown for oil production and six introduced varieties of forage rape with relatively high yield and high nutritional value were grown at the same condition and their nutritional value were observed. Generally, rape was considered as a useful forage fodder crop with high content of crude protein and low contents of NDF, ADF, hemicellulose, cellulose and lignin. Differences in mean values of the above characters between two groups of rape were not statistically significant. Velox showed significantly higher content of crude protein and significantly lower contents of NDF, ADF, hemicellulose, cellulose and lignin compared with other varieties of forage rape. Rape was relatively high in IVDMD compared with other forage fodder crops, and forage rape was more or less higher in IVDMD and DDMM than oil seed rape. Velox was the highest in IVDMD and DDMM among the varieties of forage rape in this experiment.

  • This field experiment was undertaken to find out the effect of grazing and cutting management on the forage quality and soil hardness at different legumes sown swards of the experimental field of Livestock Experiment Station in Suweon, from August 1985 to October 1988. The results obtained are as follows: 1. Crude protein, crude fat and ash contents under grazing were higher than these under cutting, but showed the reverse results in crude fiber and nitrogen free extracts contents. Average in vitro dry matter digestibility (IVDMD) under grazing (72 %) was a little higher than that under cutting (71 %). On the other hand, there was little difference among the mixtures swards in mineral contents and IVDMD. 2. The contents of Ca, P and Mg were a little high in the cutting, but K and Na contents were in gazing. Ca: P ratio in grazing (2.97) was slightly higher than that of cutting (2.94). 3. Production of energies(TDN, StE and NEL) with cutting were appeard to increase by 19.4 %, 13.5 %and 19.0 % than those of grazing, respectively. Mixtures swards including alfalfa showed more production both grazing and cutting. 4. Soil hardness in the top lOcm of soil by cattle grazing was changed from 15.5mm at startihg year to 22.6 mm after 3 years, but in cutting slightly increase from 15.5mm to 16.2mm. Generally it was low in early spring and high in autumn.

  • This experiment was carried out to examine the effects of urea-treated rice straw feeding on the growth performance of crossbred Holstein heifers under different feeding conditions. In the first experiment, the animals were given diets having 2 levels of TDN and CP and 3 levels of crude fiber (22, 30 and 36%) which were formulated with urea-treated rice straw and concentrates. Daily weight gain of heifers was not different between 22% and 30% CF diets, but the reduction of TDN or CP level to 90% of the requirements decreased the weight gain. Fiber content of 36% also reduced the body weight gain. The reduction of TDN significantly reduced DM intake and increased feed conversion ratio. Feed cost per kg weight gain was significantly increased by an increase in CF to 36%. In the second experiment, separate feeding and total mixing feeding were compared. There were no significant differences between the two feeding systems in body weight gain although the possibility of superiority in SF to TMF remained. DM intake was not affected by the feeding system, but 30% CF diet gave higher DM intake. Feed cost per kg weight gain was lower in the 30% CF diet.
