This experiment was conducted to evaluate the effect of manure and chemical fertilizer on the forage yield and quality of oat at no-tillage. The experimental design was a randomized complete block design. The three treatments were: chemical fertilizer, manure fertilizer, and chemical and manure mixture. Seedling vigor was higher at chemical fertilizer than manure, but more greener at manure application than chemical fertilizer. Dry matter (DM) content of oat at manure was higher than chemical and mixture fertilizer (p<0.05). There was no difference in DM yield, TDN (total digestible nutrients) yield, and CP (crude protein) yield of oat at no-tillage system, but the fresh yield was significantly higher in chemical fertilizer compared to manure. The CP content for oat was significantly higher in manure than chemical fertilizer. However, no significant effects were observed for NDF (neutral detergent fiber), ADF (acid detergent fiber), TDN and RFV (relative feed value) in different fertilizer application. Based on the results of this study, manure don't affected forage production and quality of no-till oat except CP content because forage oat is used off-season crop.

This experiment was conducted to determine the effect of wrap color on the quality of round baled grass silage at experimental field of Grassland and Forages Division, National Livestock Research Institute, RDA, Suwon from 1997 to 1998. The experiment was consist of randomized block design with three replications. The treatments were three wrap color(white, black and light green). Wrap color did not affect chemical composition. Fiber components(ADF and NDF) of all silages after 2 months were higher than those of forages at ensiling. Among tested wrap colors, white color wrap resulted in lower pH than others (p<0.05) but, there was no significant difference between black and light green color. Dry matter content of light green color was the highest among warp colors, but there was no signifiant difference (p<0.05). Acetic and butyric acid contents of all plots. were not found significant difference among wrap color and wrap color did not influence lactic acid and organic acid concentration. The effect of wrap color on the quality grade and DM loss also were not found significant difference. Results of this study indicate that wrap color does not influence the quality of silage.

This experiment was conducted to determine the effect of microbial inoculant on the quality of round baled grass silage at experimental field of Grassland and Forages Division, National Livestock Research Institute, RDA, Suwon from 1997 to 1998. The experiment was consist of randomized block design with three replications. The treatments were three different inoculant (control, inoculant A, B and C). The contents of ether extract(EE), crude protein(CP) and in vitro dry matter digestibility(IVDMD) in inoculant treatment plots were higher than those in control. Silages treated by Inoculant A, Band C had significantly lower acidity than that of control silage (p<0.05). Dry matter(DM) content of control silage was higher than those of inoculant treated silage. There were significant differences in organic acid contents among treatments(p<0.05). Lactic acid was increased with inoculant treatment, but, acetic and butyric acid was decreased. The DM loss of all silages were decreased with inoculant treatment and quality grade of inoculant treated silage was higher than that of control. Results of this study indicate that addition of microbial inoculant will improve the fermentation and quality of round baled grass silage.

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 breeding Korean native goat. Twelve breeding Korean native goats were divided into four treatment groups, which were fed TMR containing 20, 30, 40% of wet brewer's grain and a control group fed concentrate feed and hay, respectively. Results are summarized as follows. Dry matter contents of TMR with wet brewer's grain was 61.46-65.81%, that of crude protein was 14.42-15.59%, ADF and NDF were 28.32-28.52, 53.46-54.16%, each. These were not different by supplemental level of brewer's grain in TMR. However, NFC contents were lower according to increase wet brewer's grain in TMR. Dry matter intake of TMR supplemented with 20% of brewer's grain was tend to be higher than those of control group. CP and digestible CP intake of TMR diets supplemented wet brewer's grain was intended to higher than those of a control group. NFC and digestible NFC intake were significantly higher in control group than in WBG40 treatment(p<0.05). Digestibilities of DM, ADF, NDF and NFC 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

This study was carried out to find out the effect of seed date and rate on the agronomic characteristics and yield of forage barley in paddy field of Suwon, from 2001 to 2003. The main plots were consisted of different seeding dates such as 5th and 20th October and 5th November. The subplots were consisted of different seeding rates of barley such as 160, 190 and 220 kg/ha. Plant height was increased at the early seeding. Dry matter(DM) percentage of barley was decreased as the seeding date was delayed. Dry matter percentages of 5th and 20th October and 5th November were 47.4, 41.5 and 34.5%, respectively. Fresh matter yield of barley decreased from 30,092 to 16,018 kg/ha as the seeding date was delayed. And fresh matter yield of barley was significantly increased with the increase in the seeding rate. Dry matter yield of barley decreased from 14,230 to 5,521 kg/ha as the seeding date was delayed. And dry matter yield of barley was significantly increased with increase in the seeding rate(p<0.05). The results obtained from this study indicate that both the seeding date of 20th October and seeding rate of 220 kg/ha would be recommendable for forage yield of barley in paddy field.

This study was conducted to investigate the effects of two dry matter levels of liquid swine manure on dry matter yield and nutritive value of Italian ryegrass, rye and oats, and the chemical characteristics of soil in Jeju. This experiment tested in split plot design. Three forage crops (Italian ryegrass, rye and oats) were the main plot and four fertilizers (no fertilizer=T0, chemical fertilizer=T1, liquid swine manure with DM 2.7%=T2 and liquid swine manure with DM 5.9 %=T3) were the sub plots. Yield and nutrient contents of forage crops and soil properties were determined. Application of liquid swine manure containing 5.9% dry matter resulted in highest DM yield in all three forage crops species compared with the other treatments (p<0.01). Crude protein content(%) and crude protein yield(kg/ha) of forage crops were highest in rye compared with the other forage crops species(p<0.01). K and Mg contents of soil were higher(p<0.01) in rye than in the other species while Na contents was higher(p<0.01) in Italian ryegrass than others. Mg content of soil appeared higher in rye than in the others and higher(p<0.05) in forage crops applied with liquid manure containing 2.7% DM compared with the other species.
contents in soil was lower in rye than the other species and higher in species with chemical fertilizer. These findings indicate that most of liquid swine manure produced on local pig farms containing low levels of dry matter and other nutrients suggest a low efficiency of its use as a fertilizer. The liquid swine manure is recommended as a fertilizer for rye production in winter, compared with Italian ryegrass or oat.

This experiment was carried out to breed the cold-tolerant variety of Italian ryegrass(Lolium multiflorum Lam.) in Grassland and Forages Division, National Livestock Research Institute, RDA, Suwon from 1987 to 2005. New variety, Kowinner as a tetraploid variety was dark green in leaf color and growth habit in autumn and early spring was semi-prostrate and medium, respectively Kowinner as a medium or late-heading variety was 19th May in heading date. Flag leaf length of Kowinner was 29 cm that was the same as control variety, Hwasan 101. Length of longest stem and plant length of Kowinner were 70 cm and 97 cm that was longer 3 cm than those of Hwasan 101, respectively. Stem width of Kowinner was thicker than that of Hwasan 101. Expecially, Kowinner was very good in regrowth. Cold tolerance of Kowinner was slightly weaker than that of Hwasan 101 and slightly stronger than that of Florida 80. Dry matter(DM) yield(12,884 kg/ha) of Kowinner was 8% more than that of Hwasan 101. In vitro dry matter digestibility and total digestible nutrient(TDN) of Kowinner were 76.2 and 63.3% that was 1.6 and 0.4% lower than those of Hwasan 101, respectively.
