Soybean (Glycine max (L.) Merill) is a very outstanding material crop with high protein and oil contents. We conducted this study to evaluate forage value and usability of soybean varieties as livestock forage. Three soybeans cultivars, OT93-26, Geomjeongsaeol, and Pungwon, were evaluated for forage use in this study, and Kwangpyeongok and Yeongwoo were used as check forage corn and rice, respectively. The whole soybean plants were harvested at the R5 (beginning seed development)- and R6 (full seed)-reproductive stages for analyzing forage usability and quality. Days to harvesting of the R5 stage-OT93-26 was the shortest among the tested crops while that of Yeongwoo was 122 days. The fresh and dry matter yields of all 3 soybeans were greater at R6 stage than at R5. Crude protein of the soybean cultivars harvested had a higher compared to the rice and corn regardless of the harvesting stage. Contents of crude fiber, neutral detergent fiber and acid detergent fiber of Yeongwoo had the lowest whereas Pungwon harvested at R5 were the highest. Among the soybeans, digestible dry matter, dry matter intake, and relative feed value of R6-harvested Geomjeongsaeol and Pungwon were high more compared to those at the R5-harvested, but in case of OT93-26 those at R6 stage were inversely measured rather than those at R5 stage. In conclusion, soybean can be used as s forage with high nutritive value for livestock. Moreover, Geomjeongsaeol can be applied to develop new forage soybean varieties with high nutritive value, and R6 stage is the optimum harvesting stage in yield and quality of the tested soybeans more than R5.

This experiment was conducted to evaluate feed value and usability of soybean varieties as livestock forage. In this study, three soybean cultivars, OT93-26, Geomjeongsaeol, and Pungwon, were harvested at R5 (beginning seed development)- and R6 (full seed)-reproductive stages for analyzing feed value of soybean. Days to R5 stage harvest of OT93-26 among the three soybean cultivars was 55 days and the shortest while Pungwon took 103 days to reach at R6 stage. The R6-harvested soybeans had higher dry matter (DM) yields and crude protein (CP) content than the R5-harvested. However, both DM and CP were the highest in the R6-harvested Geomjeongsaeol. Contents of neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Pungwon harvested at R5 were the highest whereas the R6-harvested Geomjeongsaeol had the lowest. Digestible dry matter (DDM), dry matter intake (DMI), and relative feed value (RFV) of the R6-harvested Geomjeongsaeol and Pungwon were higher than those of the R5-harvested, but in case of OT93-26, those at R6 stage were low rather than those at R5 stage. However, soybean could be used as alternative forage with high feed value for livestock. Taken together, Geomjeongsaeol could be used for developing new forage soybean varieties with high feed value, and R6 would be the optimum harvesting stage for yield and quality of forage soybean.

This study was conducted from October 2014 to May 2015 to explore forage production and feed values of Italian ryegrass, Rye and whole crop barley as winter forage crops in the Southern region of Korea. The experimental location was over 10 points for each species and each sampling point area was $1m^2$ (Width: 1 m ${\times}$ Length: 1 m). Air mean temperature and rainfall in the Southern region of Korea during the experimental period was $6.95{\pm}5.75^{\circ}C$ and $70.45{\pm}54.68mm$, respectively. Fresh forage yield of Italian ryegrass, the most cultivated forage in the Southern region of Korea, was $44.4{\pm}7.0ton/ha$. The percentage of dry matter for whole crop barley was $28.9{\pm}7.0%$. Crude protein (CP) was higher in Italian ryegrass ($10.7{\pm}5.3%$) while total digestible nutrient (TDN) had the highest value in whole crop barley. Crude protein was not significantly different by location. However, the neutral detergent fiber (NDF), acid detergent fiber (ADF) and total digestible nutrient value of forage from Jeonbuk province were higher than in forage from Gyeongnam province.

This study was conducted to investigate the possibility that oil seed rape could be used as a forage fodder crop and to select the most suitable variety of forage rape at the southern area of Korea, Two varieties of oil seed rape currently grown for oil production and six introduced varieties of forage rape with relatively high yield and high nutritional value were grown at the same condition and their nutritional value were observed in Spring. Generally, rape was considered as a useful forage fodder crop with high content of crude protein and low contents of NDF, ADF, hemicellulose, cellulose and lignin. Differences in mean values of the above characters between two groups of rape were not statistically significant. Velox showed significantly higher content of crude protein and significantly lower contents of NDF, ADF, hemicellulose, cellulose and lignin compared with other varieties of forage rape in spring. Rape was relatively high in IVDMD compared with other forage fodder crops, and forage rape was more or less in IVDMD and DDMW than oil seed rape. Velox was the highest in IVDMD and DDMW among the varieties of forage rape in Spring, in this experiment.

This study was carried out to evaluate the forage yield and feed value of winter crops such as Italian ryegrass (IRG), oat, rye, barley, and hairy vetch. Forage crops were sown on 15^th October 2018 in a paddy field after harvesting rice and forage crops were harvested at two times of 25^th April 2019 and 18^th May 201 9. The highest dry matter (DM) yield was harvested from rye among the five species of forage crop on 18^th May. DM yield of all forages was increased 14.4% on 18^th May compared to 25^th April. The highest yield of crude protein (CP) was obtained from hairy vetch on 25^th April, whereas it was decreased (38.1%) on 18^th May. Moreover, the highest total digestible nutrient (TDN) yield and relative feed value (RFV) was harvested respectively from rye and hairy vetch on 25^th April. Delay of harvest time considerably increased DM yield but significantly decreased CP and RFV. In conclusion, rye was the best source of DM and TDN and hairy vetch was the high-quality feed. Rye harvested on 25^th April is the proper forage for resolving Korea's problem of insufficient forage yield.

This study was conducted to evaluate the forage yield and quality of Fesrulolium bmunii(Festuca prafensis Huds. x Lolium multiflomm Lam.) as a forage sources. The experiment was arranged in a randomized block design with four replications from Sep. 1995 to May 1998 at Chungnam University. Treatments consisted of two forage species, Festulolium bmunii(Pau1ita) and Dactylis glomerc;d4Potomac). The dry matter yields, nutritive value, N and energy balance were observed. The yields of DM, CPDM and DDM per area(ha) were higher for Potomac (P< 0.01) than for Paulita. The content of CP showed no difference between Potomac and Paulita, but NDF, ADF and lignin contents of Paulita were absolutly lower than those of Potomac (P<0.05). The retained N and energy were also high for Paulita compare to for Potomac. It could be suggested that Paulita has higher potential for improvement of the forage quality than Potomac and it have a potential to provide as a forage sources.

This syudy was conducted to increase the utility of forage rye which are suitable to be cultivated at high altitude Taekwllyong area. For that purpose two cultivars of rye (winter-more, kool-glazer) were cultivated for 3years using a randomized block design with 3 replications. The dry matter digestibility (DMD) was evaluated with the pelleted rye hay produced by adding sodium hydroxide and then the TDN value was calculated by the DMD. By adding NaOH, DMD and TDN value of rye pellets (Y=46.92+ 1.8X, ~ 0 . 9 7 )w ere increased significantly (p<0.05) and NDF (neutral detergent fiber) decrease significantly. However, ADF (acid detergent fiber) and lignin did not significantly decrease (p<0.05). Rye could be cultivated as a second crop after com at high altitude area in the same year and pelleted with NaOH in order to increase the nutritive values (p< 0.05).

This study was carried out to evaluate the seeding date and performance of early maturing rye cultivars for the Dry matter yield (DMY) and nutritive value during 2016 and 2017 in Yeongseo region of Gangwondo, South Korea. The experimental field was designed as a split-plot arrangement. The treatments were two planting dates on September 25 and October 02 as the main plots, and two cultivars of forage rye including Gogu and Koolgrazer as sub-plots. The cultivars were harvested on April 26 at the heading stage of both years. In this experiment, the sowing dates and cultivars of the forage rye did not effect on DMY. The DMY had no significant differences among the cultivars of forage rye and seeding date of both years. Similarly, no significant difference was observed in the DMY of Gogu and Koolgrazer in both seeding date and years. The CP, NDF, ADF, and RFV had no significant differences among the cultivars of forage rye and seeding date of both years. Considering the DMY and nutritive value of the current experiment, seeding of forage rye cultivars Gogu and Koolgrazer on September 25 and October 2 could be used as an recommended seeding date at northern area. In addition, based on the climate characteristics of the region, both cultivars had relatively similar forage yield and quality that makes them to be recommended for cultivation in the region. This study is meaningful in that DMY was first presented in Yeongseo region where there is no cultivation data for forage rye.
