This study was conducted to investigate the effects of the types and rates of application of animal manure on productivity of silage corn and environmental pollution in silage corn cultivation soil. The experiment was confirmed in lysimeter which was constructed with 0.30m diameter, and 1 m depth. This study was arranged in split plot design. Main plots were the types of cattle slurry (CS), swine manure fermented with sawdust (SMFS) and chemical fertilizer (CF), Subplots were the application rates of animal manure, as urea, such as 100, 200 and 400 kg N
. Dry matter(DM) and nitrogen yields of silage corn enhanced as increased application rates of CS, SMFS and CF (p<0.05). DM yield reveals that there is an decrease in order of CF>CS>SMFS (p<0.05). Crude protein (CP) contents of the whole silage corn increased as increased application rates of CS, SMFS and CF. IN addition,
content in leaching water by application of animal manure reveals that there is an decrease in order SMFS>CF>CS (p<0.05). However,
content was hardly influenced by application of animal manure, and
content increased with application rates increased.
content in leaching water by application of animal manure reveals that there is an decrease in order of SMFS>CF>CS.
increased as increasing application rates (p<0.05), whereas
in leaching water maintained a low levels.

In order to investigate the effects of genetic variations of orchardgrass in tissue culture response, calli were induced from mature seeds of eight varieties, 'Hapsung 2', '93E', 'Amba', 'Ambassdor', 'Frode', 'Frontier', 'Potomac' and 'Roughrider', and plant regeneration frequency was compared. Significant differences were observed among the varieties in both callus induction and plant regeneration. Callus induction rate of viable seeds varied from 24.3% to 71.7%. Plant regeneration frequency ranged from 76.6% to 29.7%. 'Roughrider' varieties showed higher regenerability with the frequency of 76.6%. These results can be used not only to provide additional improvements in the plant regeneration frequency from transgenic callus, but also useful for molecular breeding of orchardgrass through genetic transformation.

Effects of acetosyringone and on Agrobacterium-mediated transformation of orchardgrass were investigated. Embryogenic calli induced from 3 varieties, Frontier, Potomac and Roughrider, were infected and co-cultured with Agrobacterium EHA101 carrying standard binary vector pIG121Hm encoding the hygromycin phosphotransferase(HPT), neomycin phosphotransferase II(NPTII) and intron-containing
(intron-GUS) genes in the T-DNA region. The effects of varieties and acetosyringone(AS) concentrations on transformation and the expression of the GUS gene were investigated. Inclusion of
AS in inoculation and co-cultivation media lead to a significant increase in stable transformation efficiency. Hygromycin resistant calli were developed into complete plants via somatic embryogenesis. GUS histochemical assay and PCR analysis of transgenic plants demonstrated that transgenes were integrated into the genome of orchardgrass.

This study was conducted to investigate the effects of Total Mixed Ration (TMR) with wet brewer's grain on feed intake, nutrient digestibility and nitrogen retention of castrated Korean black goat. For feeding trial, forty castrated Korean black goats were divided into four treatment groups, which were fed TMR containing 20, 30, 40% of wet brewer's grain. For digestibility trial, twelve castrated Korean black goats were allotted to treatments in four groups of three goats. Results are summarized as follows. Dry matter (DM) contents of TMR with wet brewer's grain was
, that of crude protein was
, Acid detergent fiber (ADF) and Neutral detergent fiber (NDF) were
, each. These were not different by supplemental level of brewer's grain in TMR. However, Non-fibrous carbohydrate (NFC) contents were lower according to increase wet brewer's grain in TMR. Average daily gain of control group were higher than those from TMR with wet brewer's gain (p<0.05). Intake of DM, Organic matter (OM) and NFC of TMR supplemented with 20% of brewer's grain were higher than those of other treatments (p<0.05). Crude protein (CP) and digestible CP intake of TMR diets supplemented wet brewer's grain was intended to higher than those of a control group. Digestibilities of DM, OM and NDF in control group were higher than those from TMR with wet brewer's grain (p<0.05). Digestibilities of CP of TMR with supplemented wet brewer's grain was tend to be higher than those of a control group. Nitrogen retention of TMR supplemented wet brewer's grain was tend to be somewhat higher compared to the control group

The object of this experiment was to suggest the optimum utilization upon rye and hairy vetch crops in Daejeon area. The field trials were conducted from 2002 to 2004 at Chungnam National University in order to evaluate the dry matter yield and quality of rye, hairy vetch, and rye+hairy vetch mixtures. The experiment was designed with split plots (main plot : seeding rate as rye mono culture, hairy vetch monoculture, rye 80%+hairy vetch 20%, rye 60%+hairy vetch 40%, and sub plot : 4 cutting stages as boot, heading, anthesis, milk). The average DM yield for 2 years had a difference on seeding rate and harvesting stages. The DM yield of rye monoculture was higher than those of the other seeding rates. There were significant increases in advanced stages in all treatments. In chemical composition, they also had a difference on seeding rates and growth stages. Hairy vetch monoculture was higher in crude protein (CP) and dry matter digestibility (DMD), but lower in fibrous compound than those of the other seeding rates (p<0.01). The crude protein dry matter (CPDM) and digestible dry matter yield was higher in rye 80%+hairy vetch 20% mixture when it was harvested at anthesis to milk stages. The results of this experiment indicated that when it was harvested at anthesis to the milk stages, rye 80%+hairy vetch 20% mixture was more effective in enhancing the DM yield and forage quality in Daejeon area.

To select the forage millet variety suitable for cultivation in the reclaimed tideland, forage yield and feed value were compared for six millet cultivars grown at the Dae-Ho reclaimed tideland, Korea, from March to October in 2004. The emergency rate of summer green was 95.0% which was more than those of any other vatieties. Fresh and dry matter yield of summer green were 21,444 and 5,296 kg/ha that were more than those of any other vatieties. respectively. The content of crude protein was the highest in Shirohie variety as 18.22%. TDN (total digestible nutrient) content was the highest in Siberian variety and the lowest in Panorama variety. Considering the emergency rate, forage production and feed value, Summer green was the most suitable variety in reclaimed tidelands.

DOI : 10.5333/KGFS.2006.26.4.221
This study was conducted to investigate the effect of tall type mixtures and turf type mixtures on dry matter yield, botanical composition and quality. The experimental design includes two mixture types : Tall type mixtures; orchardgrass (Potomac) 50+tall fescue (Fawn) 20+ Kentucky bluegrass (Kenblue) 10+red clover (Kenland) 20%) and turf type mixtures; Kentucky bluegrass(Newport) 60%+tall fescue (reboil Jr.) 20+perennial ryegrass (palmer II) 20%. The DM yield was higher obtained in tall type mixture than that of turf type mixture (p<0.05). In the chemical composition, Turf type mixture was higher in crude protein (CP) and dry matter digestibility (DMD), but lower in fibrous compound as NDF, ADF, cellulose and lignin than those of tall type mixture (p<0.05). The crude protein dry matter (CPDM) and digestible dry matter (DDM) yield was higher in tall type mixture than turf type mixture (p<0.05). In this experiment, nutritive value of turf type mixture was higher than that of tall type mixture, but CPDM and DDM yield of turf type mixture were lower than that of turf type mixture due to low dry matter yield. On the other hand, turf type mixture was obtained high feed value, and maintaining the various botanical composition on the 13 th cutting frequency condition. therefore, turf type mixture had a utilization possibility under grazing livestock as sheep and milk goats.

This experiment was conducted to evaluate the effect of liquid manure source, application rate and time on the agronomic characteristics and forage yield of winter rye. The experimental design was a randomized complete block design. The treatments were : CFB150=chemical fertilizer(CF) 150 N as basal, CFS150=CF 150 N as split application (75+75), SLB150=swine liquid (SL) 150 N as basal, SLS150=SL 150 N as split application (75+75), SLB300=SL 300 N as basal, SLS150=SL 300 N as split application(150+150), CLB150=cattle liquid (CL) 150 N as basal, CLS150=CL 150 N as split awlication(75+75), CLB300=CL 300 N as basal, CLS150=CL 300 N as split application(150+150). Heading date of the plant was observed on the 17th of April fur both chemical fertilizer and swine liquid, and on the 16th of April for cattle liquid. Stay green of chemical fertilizer was higher than others because of high crude protein content. Leaf was darker in high nitrogen fertilizer treatments than low N treatments. However lodging resistance was poor as nitrogen fertilizer was increased. Dry matter (DM) content of rye at chemical fertilizer was lower than liquid manure. DM yield of chemical fertilizer treatments were highest among the fertilizer source. However, DM yield of rye with application was all most same at different N application methods. The crude protein (CP) content and yield for chemical fertilizer was significantly higher than liquid manure. CP yield using split application was higher by 16% and 28%, compared to basal application. Based on the results of this study, forage production of liquid manure was lower, compared to chemical fertilizer. And split application was superior to basal application forage and protein yields, and high protein.

The experimental work was conducted to determine the growth characteristics, yield and feed value of sorghum-sudangrass hybrid and
leaching by application of various types of livestock manure (LM) at National Livestock Research Institute, Suwon, for 3years (2003-3005). The growth characteristics in chemical fertilizer (CF) was better than others in general. The growth characteristic of sorghum-sudangrass hybrid by the various type of LM was good in order of composted swine manure (CSM) > liquid swine manure (LSM) > composted cattle manure (CSM), whereas the growth characteristics by application level of LM was good in order of LM 100%+CF 25%>LM 75%+CF 25%>LM 100%. Dry matter(DM) yield in LSM and CSM increased by 23% and 18% respectively while DM yield in CCM decreased 24% as compared to CF. Moreover total digestible nutrients (TDN) in LSM and CSM increased by 24% and 18% respectively while TDN in CCM decreased 12% as compared to CF. Crude protein and relative feed value in LM decreased compared to those in CF.
leaching by application level of LM showed that there was an increase in order of LM 100%+ CF 25%>LM 75%+CF 25%>LM 100%. Also the high concentration of
occurred shortly after application of LM.

Journal of The Korean Society of Grassland and Forage Science, volume 26, issue 4, 2006, Pages 239~248
DOI : 10.5333/KGFS.2006.26.4.239
This study was conducted not only to investigate effects of different supplementation levels of Acanthopanax senticosus leaves on feed intakes, nutrient digestibility, nitrogen retention, and blood metabolites in Korean black goats but also to obtain basic data for nutritive value of Acanthopanax senticosus leaves and production of high quality functional animal products. Twelve Korean black goats were allotted to treatments in four groups of three goats per treatment and then they were housed in individual metabolism cages with completely random arrangements for 21 days. Four treatments were separated into controls and three different supplementation levels of Acanthopanax senticosus such as 10, 20 and 30%, respectively. For the chemical composition of experimental diets, crude protein (CP) contents of controls were 13.39% and those of supplementation treatments were lowered with increasing levels of Acanthopanax senticosus. Control groups tended to have higher acid detergent fiber (ADF) and neutral detergent fiber (NDF) contents as compared to supplementation groups, but non-fibrous carbohydrate (NFC) contents tended to be higher far supplementation groups than those for controls. Feed intakes had no significant difference among treatments, but digestible dry matter amounts were significantly higher for 20 and 30% supplementation groups than those for other treatments. Dry matter intakes per metabolic body weight and their ratio per body weight were highest in 20% group, but those of 40% groups were lowest (p<0.05). Crude protein, ADF and NDF digestibilities were significantly higher in Acanthopanax senticosus supplementation groups in comparison to controls (p<0.05), and in particular, they were increased with increasing supplementation levels of tranthopanax senticosus. Nitrogen retention was significantly higher for 20 and 30% treatments than those fur controls (p<0.05). Plasma urea nitrogen concentration was significantly lower for 30% supplementation group than those fur controls (p<0.05). Furthermore, plasma triglyceride concentration was significantly lower for Acanthopanax senticosus groups than those for controls (p<0.05). The results showed that supplemental level of 20% Acanthopnnax senticosus leaves to Korean black goats improved nutrient digestibility, nitrogen retention, and plasma urea nitrogen and triglyceride concentrations. Consequently, it might contribute to more efficient production of Korean black goats.

The object of this experiment was to suggest the optimum autumn sown small forage crops as next forage crops harvested maize in Daejeon area. The field trials was conducted from 2002 to 2004 at Chungnam National University in order to evaluate the dry matter yield and qualities of the autumn sown small forage crops. The experiment was consisted of split plots (main plot : forage crops as rye, barley and wheat, and sub plot 4 harvest stages as boot, heading, milk and dough) design with three replications. The average DM yield for 2 years of rye was higher than that of other forage crops (p<0.01). As stages proceed, the DM yield tended to increase in all forage crops (p<0.01). In chemical composition, they had a difference on forage crops and stages. The crude protein (CP) was higher in barley (p<0.01), but fibrous contents such as NDF, ADF, cellulose and lignin were lower in wheat than in the other forage crops (p<0.01). In Daejeon area, although barley and wheat at milk and dough stages were observed with maximum yield and high quality as autumn sown forage crops, due to late harvesting periods, it is difficult to utilize them as previous forage crops seeded in maize. Based on the result mentioned above, it is concluded that rye harvested at boot to heading stages is the most suitable fur autumn sown small forage crops in Daejeon area. Meanwhile, in order to have the option of nutritional value in wheat and barley, they need to be supplied early maturing and high-yield variety of wheat and barley.

Studies were carried out to evaluate the effect of liquid pig manure on the production of Japanese millet, the chemical characteristics of pasture soil and leaching water. The study was undertaken from June to September 2005. Randomized complete block design was used to allot four treatments: T1 (no fertilizer), T2 (N : 200 kg/ha, p : 150 kg/ha, K : 150 kg/ha), T3 (liquid pig manure containing 1.7% DM 200 kg N/ha) and T4 (liquid pig manure containing 7.0% DM 200 kg N/ha). Leaching water was sampled at 21 August (1st time), 9 September (2nd time) and 26 September (3rd time), 2005, respectively. No significant differences in the dry matter yield of Japanese millet was found among the four treatments, whereas the plant lengths of Japanese millet were higher in the T2, T3 and T4 than in T1 (p<0.05). Nitrogen, P and K uptake of J. millet tended to be influenced by application of chemical fertilizer or 7.0% DM liquid pig manure compared with T1 or 1.8% DM liquid pig manure. The organic matter (OM) content of soil was higher in T2, T3 and T4 than in T1. Na content was highest in T3 among the four treatments.
content in leaching was not different among the four treatments.
content in leaching water sampled in 1st time was high in T4, but in T3 from 3rd time (p<0.05). Cl, Mg and Na contents were high in leaching water sampled in the 1st time from T4, whereas high in those from T3 in 2nd or 3rd time. Results show that the application of a high DM liquid pig manure is not better for producing Japanese millet and improving the properties of pasture soil than a low DM liquid pig manure. However, the contents of
, Cl, Mg and Na in leaching water sampled in 1st time were high in a high DM liquid pig manure.

To investigate the physiological responses to winter freezing stress naturally occurring, the level of lipid peroxidation and enzymatic antioxidant responses were compared between zoysiagrass and creeping bentgrass during overwintering. Root mortality of creeping bentgrass was significantly higher than zoysiagrass at January. Root growth of creeping bentgrass was nearly parallel with temperature fluctuation, while zoysiagrass showed little changes in root growth until the end of April. Total nonstructural carbohydrate of zoysiauass was 10% higher than creeping bentgrass. Malondialdehyde(MDA) content in creeping bentgrass was 2-fold higher than that of zoysiagrass. The peroxidase(POD) activity of creeping bentgrass in January was 4.2 times higher, while superoxide(SOD) and catalase(CAT) activities lowered 22% and 67%, respectively, compared to zoysiagrass. These results suggest that zoysiagrass roots much properly operate cold tolerance mechanism and: are less susceptible to cold stress in comparison to creeping bentgrass.

Seed priming is a useful technique for early establishment of seedling. In this experiment, the conditions for priming of pasture seeds (tall fescue, orchardgrass, alfalfa and white clover) have been optimized to ensure an early germination and more uniform growth of seedlings. The experiment was conducted in a split plot design with three replications. The main plots consisted of five different materials such as
and PEG. The subplots were consisted of three chemical concentration groups such as 500mM (or 10%), 100mM (or 20%) and 200mM (or 30%). Effect of priming materials and its concentrations were different in all four pasture seeds examined. Chemical concentration did not show any significant effects on the germination of tall fescue, however, germination of tall fescue primed with
materials were higher than the others. The concentration of prime materials did not affect on the germination of orchardgrass, but germination of orchardgrass primed with
was showed better result than the other materials examined. The seeds of alfalfa and white clover primed with PEG showed better germination capability than the other priming materials. In addition, chemical concentration of primed seeds also showed significant difference on the germination of alfalfa and white clover. These results suggest that seed priming induced earlier and higher germination for all four pastures tested. However, the, degree of priming effectiveness on pasture species depending on the priming materials and its concentrations.

This study was conducted to evaluate the dry matter yield and forage quality of Kenaf in relation to planting density and growing days in Cheorwon area from 20 May to 12 September in 2005. The experiment was laid out in a split plot design with three replications. The main plots consisted of planting density and growing days with three cultivars of Kenaf as sub-plots; Bowling, Everglade and Tainung. The results obtained were summarized as follows. The dry matter yield increased until 92 days after planting at
planting density, but decreased after the day. The dry matter yield increased with maturity in all three cultivars, especially Dowling showed the highest dry matter yield at each harvest time. The Crude Protein (CP) contents of all three cultivars decreased with maturity. Especially, the decrease in the CP contents was greater in the early stage than in the late stage. The planting density did not affect the CP contents, even though they are little higher in
planting density. The higher CP contents were obseued in Dowling, which is not significant. No difference in the Neutral detergent fiber (NDF) and Acid detergent fiber (ADF) contents was observed in the planting density and cultivar, although the increasing tendency was found with maturity. These results suggest that Kenaf can be a good potential forage crop in the northern area of Korea, especially Dowling showed the great dry matter yield and forage quality when harvested on Day 104 at
