  • Cassia mimosoides var. nomame was grown at five seeding rates (10, 20, 30, 40 and 50 kg/ha) from March 31 to September 21, 1998 at Cheju to determine influence of seeding rate on agronomic characters, and forage yield and quality. Days to flowering increased from 126 to 129 days as seeding rate increased from 10 to 50 kg/ha. The plant height increased from 86 to 99 cm as seeding rate was increased from 10 to 30 kg/hac and then decreased to 93 cm at a rate of 50 kglha. With increasing seeding rate, stem diameter quadratically decreased and the number of branches and green leaves per plant linearly decreased but the number of withering leaves per plant linearly increased. As seeding rate increased &om 10 to 30 kg/ha, fresh forage, dry matter, crude protein, and total digestible nutrients (TDN) yield increased 'from 30.7 to 49.1, 7.5 to 12.2, 0.90 to 1.57 and 4.09 to 7.09 MTha, respectively, and then decreased with further increased seeding rates. Crude protein, ether extract, nitrogen free extract, and TDN wntent increased 12.1 to 14.2% 2.2 to 2.9%, 35.1 to 39.2%, 54.8 to 60.3% respectively, but crude fiber wntent decreased 39.8 .to 33.3% and crude ash declined 4.9 to 3.8% as seeding rate increased from 10 to 50 kgiha. The optimum seeding rate to obtain the highest TDN yield was estimated to be 36kglha. (Key words : Cassia mimosoides var. nomame, Seeding rate, Forage yield, Forage quality)

  • The chemical composition of fish feeds(mackerel, gizzard shad, shrimp and formula feed) were analyzed and compared with those of untreated and irradiated (5 kGy) feeds, and the effects of gamma irradiation (5 kGy) and butylated hydroxyanisole (BHA, 200ppm) on feeds spoilage were investigated by determination of thiobarbituric acid (TBA) value and peroxide value for 14 days at $20^{\circ}C$, $4^{\circ}C$ or $-20^{\circ}C$. Crude protein, crude lipid, crude fiber, crude ash and nitrogen free extract were not significantly changed by gamma irradiation with the dose of 5 kGy. Immediately gamma irradiation increased the initiative oxidation of feeds as expected. But BHA was found to be greatly effective in minimizing the radiation-induced peroxidation (p<0.05). The TBA value and peroxide value increased with the elapse of the storage period. The level of lipid oxidation was increased depending on the rise in storage temperature. But the additions of BHA inhibited the lipid oxidation (p<0.05).

  • This experiment was conducted to increase essential oil and aromatic contents on roots of Codonopsis lanceolata Trautv with different shading treatments. Vine length was prolonged by shading treatment compared with non-shading. Fresh root weight in 75% shading treatment was highest with 13g per plant. Crude components such as crude protein, fat and fiber contents decreased, while crude ash increased as shading degree increased. Forty-eight volatile aromatic compounds in the root were identified by GC/MS. Major aromatic compounds were 1-hexanol, cis-3-hexanol, and trans-2-hexanol. In particular, trans-2-hexanol was highest in the 75% shading treatment attaining the 160.32 % area. Conclusively, it was suggested that the 75% shading treatment was to some extent effective to improve the content of essential oil and aromatics in the roots of Codonopsis lanceolata Trautv.

  • The quality of the rice straw silage added with apple pomace was investigated in this study and the amount of apple pomace added in different treatments were 0, 20, 40 and 60%, respectively. Crude protein contents (6.4-7.5%) of rice straw silage added with apple pomace were significantly (P<0.05) higher than that of 100%. rice straw silage (5.3%), however, crude ash contents were lower (P<0.05) in supplementation of apple pomace. The trends of changing chemical composition between raw materials and end products of silages particularly in the contents of crude protein and crude ash were more apparent in the silages added with apple pomace by 40-60%. Values of pH and the contents of lactic acid and total acid in 40-60% apple pomace added silages were 3.9-4.1, 1.0- 1.5% and 2.7-4.5%, respectively which were significantly (P<0.05) higher than those of 4.6, 0.02% and 0.34% in 100% rice straw silage, respectively. In situ dry matter (DM) and neutral detergent fiber (NDF) disappearance rates in the rumen in the treatments of 40- 60% apple pomace added silages were significantly (P<0.05) higher than those of 100% rice straw silage particularly since after 3 and 24 hour incubation on DM and NDF disappearance, respectively. Although quickly degraded fraction (a) among the treatments were not significantly different, 28.4-28.5% of slowly degraded fraction (b) and 27.2-27.4% of effective degradability (ED, k=0.08) for DM were significantly (P<0.05) higher than those of 100% rice straw silage (12.5 and 24.6% respectively). NDF was in the same trend as in DM. 31.6-63.2% of NDF for b fraction and 18.7- 19.4% for ED in 40-60% apple pomace added silages were significantly (P<0.05) higher than those of 100% rice straw silage (12.4 and 17.6% respectively).

  • Twelve indigenous male goats, comprising of six intact and six castrated (2.5-3 years; $24.4{\pm}0.62kg$) were assigned evenly into two dietary treatments, viz. $I_0$ and $I_{100}$ and were used to study the effect of supplementation of iodine on the nutrient utilization when their diet contained Leucaena leaf meal. They were offered a conventional concentrate mixture along with Leucaena leucocephala leaf meal, the latter to meet 50% of their crude protein (CP) requirements, and supplemented with either no iodine ($I_0$) or 0.1 mg of iodine ($I_{100}$)/day/animal as potassium iodide for a period of 105 days. Wheat straw given ad libitum was the sole source of roughage. A metabolism trial of 8 days duration was conducted after 90 days of experimental feeding. It was observed that the overall dry matter (DM) intake during experimental period was higher (p<0.05) in $I_{100}$ group as compared to $I_0$ group (508.6 vs. $443.7g\;d^{-1}$). The intake of CP, digestible crude protein (DCP) and metabolisable energy (ME), although non-significant, tended to be higher in the iodine supplemented group, $I_{100}$. Digestibility of dry matter, organic matter (OM), CP, ether extract and crude fiber (CF) did not differ (p>0.05) between the treatments. However, nitrogen retention was higher (p<0.01) in $I_{100}$ than $I_0$ with the values being 2.63 and $1.70g\;d^{-1}$, respectively. No difference (p>0.05) was evident in the retention of calcium and phosphorus between the two groups. The castrated animal exhibited lower DM intake concurrent with higher digestibility of DM and crude fibre (p<0.05), and organic matter and total carbohydrates (p<0.01) when compared to intact ones. It was concluded that supplementation of iodine to leucaena based ration may help in improving the DM intake and nitrogen utilization by goats.

  • The composition of two Bokbunja (Rubus coreanus Miquel) wines (one without mushroom extracts (wine A) and the other is with the extracts (wine B)) has been investigated to improve the quality of Bokbunja wine. The content of solid particle, acidity, crude ash, crude protein of the wine A were 10.5%, 1.36%, 0.45% and 0.05% and those of wine B were 7.4%, 0.54%, 0.31%, and 0.22%, respectively. Crude fat and crude fiber were not detected in both samples. To verify the flavor quality of Bokbunja wine, the volatile components from ethylether extracts of two wines were analyzed using GC/FID and GC/MS. A total number of 12 volatile flavor compounds (6 alcohols, 3 ketones, 1 acid, 1 ester and 1 anhydride) were identified in the two Rubus wines. The major volatile compounds of the wines were 2,3-butanediol, 2,5-furanedione, phenylethyl alcohol, and butanedioic acid and they might affect the major role in the unique flavor of Bokbunja wines.
