This experiment was carried out to compare chemical composition, TDN yield of corn-soybean intercropping and corn monocropping forage plants at different harvesting time and obtained the following results. 1. In both cropping systems, the content of chemical composition of forage were changed same pattern in growing stage. The content of crude protein in corn-soybean intercropping forage at yellow stage increased more than that of corn nonocropping forage, while the crude fat in corn monocropping forage plants increased than that of corn-soybean intercropping forage plants at mature stage. 2. The crude fiber, crude ash, ADF content of forage plants in both cropping system decreased same pattern in growing period, however, NFE content of forage increased with maturity. 3. TDN yield of corn-soybean intercropping and corn monocropping forage plants at yellow stage obtained similar results and TDN yield per 10a in intercropping and monocropping were 1006.lkg and 978.6kg, respectively. 4. Consequently, corn-soybean interaopping system could be increased crude protein yield without decreasing of dry matter yield in comparison with corn monocropping system for corn silage.

In order to study the effect of honey concentration on the quality of honeyed ginseng in the process of manufacturing honeyed ginseng, honeyed ginseng was manufactured under the various condition of honey concentration, 40 brix, 50 brix, 60 brix and 70 brix and the approximate composition, the yield and organoleptic test of them were investigated. The results obtained were as follows. 1. The higher honey concentration was used, the yield of honeyed ginseng was increased. 2. The higher honey concentration was used, the amount of total sugar was increased while the amount of crude saponin, crude protein. crude fat, crude fiber and crude ash was decreased. 3. Free sugars of honeyed ginseng consist of rhamnose, xylose, fructose, glucose, sucrose and maltose, 4. The amount of saponin lost in the process of manufacturing honeyed ginseng was 2.5%-5.0%, therefore honey concentration was not so effective on the loss of saponin. 5. According to organoleptic test, H-3 and H-2 treating honey concentration at 60 brix and 50 brix was the best and better of all.

A number of correlation and regression analyses were performed on data from apparent and true digestibility of amino acids at ileal and fecal level with finishing pigs, in order to investigate whether these amino acid digestibilities could be predicted with certainly degree on their fiber fractions content (chemical analysis). The data comprised 16 diets varying in 4 levels of crude fiber and from 4 fiber sources. The relationships between fiber fractions including crude fiber (CF), NDF, ADF lignin and cellulose contents on apparent and true digestibility of almost all amino acids in both ileal and fecal level were negative, except glutamine at fecal level. In apparent digestibility at ileal level, the correlations of fiber fractions were moderate (r of NDF = 0.53 to 0.63; ADF, 0.50 to 0.77; cellulose, 0.50 to 0.75), with an exception of CF content was relatively high (r of 0.58 to 0.81). The correlations to true digestibility of amino acids were weaker. In case of at fecal level, the higher correlation (negative) was found with NDF than CF content. Estimations of amino acids digestibility were performed using regression equation. The data showed that apparent digestibility of amino acids could be estimated for almost amino acids except arginine, threonine, valine and tyrosine at fecal level and phenylalaine, valine and glycine at ileal level. The best prediction at ileal and fecal level ($r^2=0.55-0.77$ and 0.52-0.76), respectively was obtained with NDF content. Prediction for true digestibility of amino acids, none of fiber fractions could be estimated for arginine, leucine and valine at all collection levels. At ileal level, CF could be used for most of amino acids except phenylalanine, glycine and praline; cellulose, only for lysine and methionine and NDF, only for proline. At fecal level, glutamine digestibility could be estimated only from CF and ADF content. The best predictor at ileal level was ADF content whereas at fecal level was NDF content. These results indicate that lignin content could not be used as predictor for all amino acids at both levels neither in apparent nor true digestibility.

This experiment was carried out in order to study the effect of fertilizer application and seasonal changes on the productivity of the native reed (Phragmites communis Trinius) on the reclaimed tidal flate in Chonnam province. The samples of reed were taken at about 30-days interval from May to October, 1982 and evaluated plant height, blade & sheath-stem ratio, grass yield, the feed compositions and in vitro dry matter digestibility (IVD). The results are summarized as follows: 1. Plant height, grass yield, crude protein content and in vitro dry matter digestibility of the reed were significantly increased by fertilizer application, and ADF content was significantly decreased. 2. According to the significance test of coefficience, there was a significant negative correlation (P<0.05) between in vitro dry matter digestibility and plant height, grass yield, and the content of crude fiber and ADF, but a positive correlation (P<0.05) between in vitro dry matter digestibility and blade & sheath-stem ratio, and the content of crude protein and crude fat.

The purpose of this study was to investigate quality characteristics of the meat batter containing dietary fiber extracted rice bran. The formulations of meat batters were manufactured in a model system with 2% raw rice bran and 2, 4, 6% levels of dietary fiber extracted rice bran, respectively. The proximate compositions of dietary fiber extracted rice bran were 53.27% dietary fiber, 6.10% crude fat, 22.99% crude protein, 12.78% crude moisture, and 7.41% crude ash. Compared with control of uncooked meat batter, the pH value of all treatments were significantly different(p<0.05). The pH of cooked meat batter were similar to uncooked meat batter. $CIE\;L^*-\;and\;CIE\;b^*-value$ of uncooked meat batter containing dietary fiber extracted rice bran were lower than control, but CIE $a^*-value$ of treatment was higher than those in control(p<0.05). All treatments had significantly lower cooking loss and emulsion stability than control(p<0.05). Compared with control, viscosity of the treatments containing dietary fiber extracted rice bran were observed significantly higher than those in control (p<0.05). And then hardness, cohesiveness, gumminess, and chewiness of treatments were higher than in control(p<0.05). Conclusively, the results of this study showed that addition of dietary fiber extracted rice bran affected the high quality properties of meat batter.

Proximate compositions of black rice and antioxidative effects of its methanol extract on refined perilla oil were investigated. Black rice seeds were composed of water 12.4%, crude protein 7.9%, crude fat 2.2%, crude fiber 1.0%, ash 1.4% and N-free extract 75.1%. The hexane and 80% methanol fractions in yields were higher than 80% ethanol and chloroform. In AOM(active oxygen method) test, antioxidative effects of black rice added to the refined perilla oil was increased with dose-dependent fashion in concentration of the black rice extracts. Among several extracts tested, 80% aqueous methanol extract showed the highest antioxidative activity, followed by hexane, chloroform, in that order. The peroxide value and TBA value for their antioxidation stability were also lower than that of control. This result was similar to that of AOM test.

Mixed feeds and their components are a very diverse matrix compared to other agricultural products worked on with NIRS classically. On a database of mixed feeds and their components (n=2.500) universal PLS calibrations and “local” calibrations were compared. The results from validation (n=600) show the potential of the calibrations and their limitations. Crude protein, crude fiber, crude fat, sugar and starch are predicted with SEPs of 0.6%, 1%, 0.3%, 1% and 1.5%, respectively. Ash content of 15% and more in several mixed feeds or components as well as rare components limit the use of NIRS for routine analyses.

This study was conducted to investigate 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 in Spring. 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 in spring. Rape was relatively high in IVDMD compared with other forage fodder crops, and forage rape was more or less in IVDMD and DDMW than oil seed rape. Velox was the highest in IVDMD and DDMW among the varieties of forage rape in Spring, in this experiment.
