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).

The studies of isolation and physiological characteristics of mesophilic or thermophilic bacteria from thermophilic oxic process (TOP) treating Chinese restaurant wastes were conducted. Chinese restaurant wastes were consist of moisture; 75.8%, solids; 24.2% and ash; 0.49%. The volatile solid was about 99% of total dry solids. In wastes used in this experiment, there was content of crude protein; 4.47%, crude lipid; 3.56%, free sugar, 0.4% , crude starch; 10.34% and crude fiber 3.14%, respectively. And then it has about 4,970 kcal/kg-dry solid of Chinese restaurant wastes. From TOP treating the chinese restaurant wastes, 37 strains of mesophilic or thermophilic bacteria were primarily isolated using medium used for the isolation and among them 6 strains of thermophilic and 7 strains of mesophilic bacteria were selected by testing the activities of amylase, cellulase, protease and lipase. TB-1, TB-9 as thermophilic bacteria and MB-15-1, 15-2, MB23 as mesophilic bacteria having strong enzyme activity were selected among isolated strains. All selected strains reduced nitrate to nitrite and they utilized glucose, manose, manitol, and maltose as carbon source. From these MB15-2 was identified as Bacillus cereus, TB1, Bacillus licheniformis and TB9; Bacillus schlegelii.

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.
