Two experiments were conducted to investigate the effects of molasses supplementation to silage materials in ensiling Galgeuntang (herbal medicine) meal on the quality of silage, and its palatability in Korean native goats. In experiment I, molasses was added at the levels of 0, 0.5, and 1.0% to Galgeuntang meal with three replicates per treatment. In experiment II, three 1.5-yr-old Korean native goats were used to measure palatability. In experiment I, lactic acid contents in molasses treatments were significantly(p<0.05) higher, and pH and butyric acid contents were lower than those of non-molasses treatment. In addition, molasses treatment increased total microbial cell counts in MRS medium for lactobacillus, but decreased total microbial cell counts in PDA medium for fungi. Molasses supplementation to silage materials increased in vitro dry matter disappearance. Molasses supplementation tended to increase silage intake in Korean native goat (experiment II), but the difference was not significant(p>0.05). It is concluded that molasses supplementation to silage materials in ensiling herbal medicine meal could improve its preservability and palatability, the higher the better.

Two experiments were conducted to investigate the effects of molasses supplementation levels to silage materials in ensiling herbal medicine meal on the quality of silage, and its palatability in Korean native goats. In experimentⅠ, molasses were added at the levels of 0, 0.5, and 1.0% to herbal medicine (Deasihotang) meal, with three replicates per each level. They were kept at room temperature for 40 d in glass bottles in order to get silage samples. In experiment Ⅱ, nine 1.5-yr-old Korean native female goats were employed to measure their palatability. In experimentⅠ, lactic acid contents in molasses treatments were significantly (p<0.05) higher, and pH and butyric acid contents was lower than those of non-molasses control treatment. In addition, molasses treatments increased total microbial cell counts in MRS medium for lactobacillus, but decreased total microbial cell counts in PDA medium for fungi. Molasses supplementation to silage materials increased in vitro dry matter disappearance rate. Molasses supplementation tended to increase silage intake in Korean native goat (experiment II), however, the difference was not significant. It is concluded that molasses supplementation to silage materials in ensiling Daesihotang meal could improve its preservability and palatability, the larger the amount the better the quality.

Two experiments were conducted to investigate effects of molasses addition to silage materials in ensiling Socheongryongtang meal on the nutritive quality of silage, palatability and various ruminal parameters in Korean native goats. In Experiment 1, Socheongryongtang meal silage was produced by the addition of 0, 0.5, or 1.0% molasses and stored for 40 days at room temperature. There were three replicates per treatment. Lactic acid contents of Socheongryongtang meal silage containing molasses(0.5 and 1.0%) were significantly(p<0.05) higher than that of the control(0%). However, the pH and butyric acid contents of Socheongryongtang meal silage containing molasses(0.5 and 1.0%) were lower than those of the control(0%). In addition, molasses(0.5 and 1.0%) increased the number of lactobacillus, but decreased the number of fungi in Socheongryongtang meal silage. In vitro dry matter disappearance tended to increase by molasses addition. In Experiment 2, three 1.5-yr-old Korean native female goats were employed in cross-over design to measure the palatability and various ruminal parameters of Socheongryongtang meal silage. Feed intake of Socheongryongtang meal silage containing molasses(0.5 and 1.0%) for 30 min significantly higher than that of control(0%). Silmilar trend was found when the feed intake was measured for 6 hr. In various ruminal parameters, molasses addition to silage materials increased propionic acid(P) and total volatile fatty acid contents, but decreased pH, acetic acid (A), and butyric acid. The A/P ratio was the lowest in 1.0% molasses treatment group. It is concluded that molasses addition in ensiling Socheongryongtang meal could enhance its nutritional quality and lengthen storage period. Also the palatability of silage was improved by the addition of molasses.

Objective of this study was to investigate characteristics of inorganic components contained in liquid fertilizer produced using seaweed by adding microorganisms and molasses. Addition of dry yeast to liquid fertilizer resulted in little change in pH and considerable increase in EC with high EC value compared to other liquid fertilizers which have microorganisms additives. Also, it was appeared that the dry yeast-added treatment had higher $NH_4-N$ concentration than other treatments. In the other hand, addition of molasses resulted in low pH compared to the control which has no additives, and EC was not different depending on the amount of molasses. $NH_4-N$ concentration in the 2% molasses added treatment was lowest and it showed a significant difference in the no and 1% molasses added treatments. In conclusion, it was shown that addition of dry yeast to liquid fertilizer increased ammonium nitrogen concentration by accelerating nitrogen mineralization, while molasses has an effect of inhibiting nitrogen mineralization. With application of organic liquid fertilizer containing seaweed increased the fresh weight of chinese cabbage.

This experiment was conducted to investigate the effects of molasses and $Phellinus$ $linteus$ meal supplementation on the quality of Korean herbal medicine silage. Herbal medicine meal silages were produced by the addition of 0, 15, and 30% of $Phellinus$ $linteus$ meal and 0, 1, and 2% of molasses ($3{\times}3$ factorial design) and stored for 40 days at room temperature. There were three replicates per treatment. Its quality such as chemical composition, pH, organic acids, the number of microorganisms and $in$ $vitro$ dry matter disappearance were determined. As the $Phellinus$ $linteus$ meal level increased, crude protein and crude fat contents increased significantly, but the acid detergent fiber (ADF) content decreased significantly. As the addition of $Phellinus$ $linteus$ meal decreased, and molasses increased, pH tended to decrease, but the lactic acid content trended to increase. The acetic acid content was lower in a higher level (30%) of $Phellinus$ $linteus$ meal, and higher in a higher level (2%) of molasses. As the $Phellinus$ $linteus$ meal level increased, the butyric acid content decreased, and butyric acid of molasses treatment was higher than that of non-supplemented control. Molasses increased the number of Lactobacillus, but decreased the number of fungi in silage. A lower level of $Phellinus$ $linteus$ meal increased the number of Lactobacillus, but decreased the number of fungi. $in$ $vitro$ dry matter disappearance tended to increase by the addition of $Phellinus$ $linteus$ meal and molasses. It is concluded that the addition of molasses and $Phellinus$ $linteus$ to herbal medicine meal silage could enhance its nutritional quality. It is considered that proper levels of molasses and $Phellinus$ $linteus$ meal in herbal medicine meal silage were 2 % and 15% respectively.

When Saccharomyces cerevisiae MTY62, a high-RNA content yeast, was cultivated by fed-batch mode feeding molasses and com steep liquor, the cell density less than 45g-DCW/L and the RNA content less than 140mg/g-cell were obtained, indicating that unknown compounds inhibiting the cell growth and RNA accumulation are contained in the molasses. Therefore, in order to obtain higher levels of cell density and RNA content, $Ca^{++}$, $Cu^{++}$and $K^{+}$ ions in molasses were removed by pretreatments of molasses with various agents such as IonClear BigBead, $Na_2$$HPO_4$, $H_2$$SO_4$, citric acid, $K_2$$HPO_4$, and EDT A. Among them, IonClear BigBead, $Na_2$$HPO_4$, and EDTA gave the highest $Ca^{++}$ removal efficiency of about 60-90%. In the batch culture with pretreated molasses, the cell concentration of 18.6g-DCW/I and RNA concentration of 3127 mg/I, maximum specific growth rate of 0.459$h^{-1}$ , and specific consumption rate of reducing sugar of 1.28g-sugar/g-cell-h were obtained, which are about 10%, 17%,47%, and 36% higher levels, respectively, over the batch culture with untreated molasses.

Objective of this study was to investigate characteristics of inorganic components contained in liquid fertilizer produced using bone powder and rice bran by adding dry yeast and molasses. Addition of dry yeast to liquid fertilizer resulted in little change in pH, considerable increase in EC, and it showed high EC value compared to the control which has no additives. Also, it was appeared that the dry yeast-added treatment had higher at $2,936mg{\cdot}L^{-1}$ of $NH_4$-N concentration than the control which had $1,782mg{\cdot}L^{-1}$. In the other hand, addition of molasses resulted in low pH and slightly low EC, as compared to the control. $NH_4$-N concentration in the no added molasses treatment was $2,936mg{\cdot}L^{-1}$ higher than its molasses added treatment which had $2,378mg{\cdot}L^{-1}$. In conclusion, it was shown that addition of dry yeast to liquid fertilizer increased ammonium nitrogen concentration by accelerating nitrogen mineralization, while molasses has an effect of inhibiting nitrogen mineralization and enhancing the characteristics of fermentation. With application of organic liquid fertilizer containing bone powder and rice bran increased the fresh weight of Allium tuberosum.

This study was conducted in order to determine a proper level of molasses addition through the analysis of changes in appearance, nutritive and silage parameters before and after ensiling or deepstacking of broiler litter, to evaluate the effect of pelleting processed broiler litter and to develop methods to enhance palatability of broiler litter and reduce the adjustment period by ‘Hanwoo’ steers. Molasses addition was effective in ensiling and deepstacking of broiler litter and the proper addition level was about 5%. Changes in nutritive values of broiler litter by ensiling and deepstacking with or without molasses treatment were not great. Adding 5% molasses at deepstacking of broiler litter did not affect(P<0.05) in vitro digestion of dry matter and organic matter. Pelleting of broiler litter resulted in significant(P<0.05) moisture evaporation, organic matter reduction and nearly threefold increase of bulk density. Pelleting or molasses addition of broiler litter improved palatability by ‘Hanwoo’ steers and reduced the adjustment period by half(8-9 d).

To compare the denitrification efficiency, this study used molasses and methanol were used as external carbon sources. Specific experimental conditions were classified according to C/N ratio conditions. The batch test showed that the denitrification efficiency increased as C/N ratios of molasses and methanol rose. The most suitable C/N ratio of molasses turned out 4:1 considering the concentration of the residue chemical oxygen demand (COD) and the denitrification efficiency, which was 91.4%. Specific denitrification rate (SDNR) drawn as a kinetic factor demonstrated that molasses and methanol showed similar SDNR values as C/N ratios of molasses and methanol increased. Under the condition of C/N ratio 4:1, 0.0292 g $NO_3{^-}-N$ removal/g mixed liquor volatile suspended solid (MLVSS)/day (molasses), 0.0299 g $NO_3{^-}-N$ removal/g MLVSS/day (methanol) were found. Sludge adapted to molasses showed that Bacterium Pseudomonas sp. and Bergeylla sp. dominated through an analysis of microbial community. In addition, some bacteria were high convergences than the variety of microbial community. Accordingly, it was assumed that molasses focus on growing microorganisms specialized in denitrification and applied as a replaceable external carbon source that can enhance denitrification performance.
