This experiment was carried out to know the possibility for cultivation of Italian ryegrass (Lolium multiflorum Lam.) by spring seeding in Grassland and Forages Division, National Institute of Animal Science, RDA, Cheonan from 2007 to 2008. In spring seeding cultivation, heading date of early maturity variety, `Kospeed`, was on 14 May, but late maturity variety, `Hwasan 101`, was not heading up to harvesting date. Dry matter yield of `Kospeed` (6,819 kg/ha) was higher than that of `Hwasan 101` (4,409 kg/ha) by 55%. Crude protein (CP) and total digestible nutrients(TDN) of `Kospeed` were 15.6% and 62.1%, respectively and that of `Hwasan 101` were 20.3%, and 67.5%. In these result, when cultivation of Italian ryegrass by spring seeding, selection of early maturity variety have a decided advantage for high productivity.

This study was carried out to determine the forage production and quality of Italian ryegrass (IRG) and forage barley sown in early spring in Suwon, 2009. The five treatments used in this experiment were IRG Kowinearly (early maturity), IRG Kowinmaster (medium maturity), Yuyeon barley, Kowinearly + Yuyeon mixture, and Kowinmaster + Yuyeon mixture. The lodging was observed in IRG, but no lodging was found IRG + barley mixtures. The heading date of Kowinearly and Kowinmaster were 16 May and 22 May, respectively, and that of barley was 13 May. The dry matter (DM) percentage at harvest was 22.2~27.6%. The forage quality among treatments were similar, but the crude protein (CP) content of IRG was higher than that of barley, and in vitro DM digestibility was a little low in Kowinmaster. The yields of DM, CP and digestible DM were high in Kowinearly + Yuyeon barley mixtures as a 13,816 kg, 1,384 kg and 10,387 kg per ha, respectively (p<0.05). In conclusion, the mixture cultivation of IRG and forage barley was very effective, because of preventing of IRG lodging, increasing of forage yield, and stable production of forages. The optimum harvest date for silage manufacture of IRG and barley sown in early spring was recommended early June instead of May.

Until now, The experiment about the forage crop have been almost not conducted on the reclaimed land. Therefore, this experiment was carried out in order to know productivity of summer forage crop using slurry composting-biofilteration (SCB) liquid fertilizer on reclaimed land of Hwaong and Sukmoon in korea from 2008 to 2009. The forage crops used in this experiment were corn and sorghum
sorghum hybrid which are used as summer forage crops in South Korea. The experiment was treated with chemical fertilizer (CF), swine slurry (SS) and SCB liquid fertilizer. Dry matter (DM) yield of corn was higher than those of sorghum
sorghum hybrid in both reclaimed lands but the effect of SCB liquid fertilizer was not appeared. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of corn were lower than those of sorghum
sorghum hybrid. The crude protein (CP) content and in vitro dry matter digestibility (IVDMD) of corn were higher than those of sorghum
sorghum hybrid. In generally feed values of corn were higher than those of sorghum
sorghum hybrid. The results of this study showed that summer forage crop cultivation using uses SCB liquid fertilizer on reclaimed land are possible.

A study was conducted to determine the effects the of cattle manure application on forage yield, quality and soil in orchard grass pasture at the experimental field of Subtropical Animal Experiment Station, National Institute of Animal Science from 2008 to 2009. The experiment was arranged in a randomized complete block design with three replications. The treatment consisted of chemical fertilizer (CF N-200 kg/ha), cattle manure 50% (basis N, CM50%), CM100% (basis N), CM200% (basis N). The dry matter (DM) yield of CM200% was the highest among the other treatments. CF showed the highest average crude protein (CP) content by 12.4% and CM50% showed the lowest content by 11.0%. Average acid detergent fiber (ADF) and neutral detergent fiber (NDF) content were 30.4 and 69.7% respectively. All treatments have narrow range of total digestibility nutrient (TDN) from 64.0% to 69.1%. But there were big difference between treatment in forage nitrate content. Changes of physical and chemical properties of soils for applications of CF 200% and CM 200% was clearly in cattle manure application. Especially, CM application in pasture increased CF application with respect to soil pH, organic matter (OM), and avaliable phosphorous (
) contents of soils.

This study was carried out to establish the optimum pre-wilting time for the high-quality silage production of whole crop oat. Plants were harvested for three time at intervals of 10 days after heading (DAH) and silage production was conducted after the pre-wilting treatment of 0, 4, 8 and 32 hours, respectively. Results showed to attain a proper moisture content for profitable silage production, which was an optimal content for making silage, by pre-wilting oat for 4 hours after harvest at either 20 days after heading or harvesting 30 DAH(days after heading). As the feed value of silage, the processing of proper moisture contents showed that crude protein contents were high and the entire feed value showed higher than others. High content of lactic acid and the low content of acetic and butyric acid showed on 60~65% the moisture conditions of silage. There was desired that whole crop oat was pre-wilting on 4 hours and harvested at about 20~30 DAH and after that, even if harvesting at once, it was judged that it could produce good quality silage.

Three Hanwoo steers (BW
) with ruminal and duodenal cannulae were used to investigate nutrients degradability and total digestible nutrient (TDN) of whole crop rice silage (WRS) harvested at different mature stages using in situ technique. Crude protein content (mean 4.81%) decreased with progressed maturity at harvest except for WRS harvested at yellow stage. Ruminal dry matter degradability of WRS at milk stage tended to be slightly lower than that of the other stages during the entire incubation time from 12 h post-incubation. The rapidly degradable N (a-fraction) of WRS harvested at milk stage was significantly (p<0.05) higher than that of WRS at dough stage whereas the slowly degradable N (b-fraction) of WRS harvested at yellow and dough stages were statistically (p<0.05) higher than those of the other WRS. Effective protein degradability (EPD) of WRS harvested at yellow stage was numerically (compared with dough and milk stages) and statistically (compared with mature stage) higher than EPD of the other WRS. Protein digestibility of WRS at different gastric tracts did not differ (p>0.05) between the harvest stages. TDN of WRS harvested at yellow stage in Hanwoo steers was statistically (compared with milk stage) and numerically (compared with dough and mature stages) higher than TDN of the other WRS. Overall, taking present feed evaluation into consideration, WRS harvested at yellow stage may be recommended for Hanwoo steers. Further studies on in vivo rumen fermentation pattern and minimizing nutrients loss during harvest should be required for accurate feed evaluation.

This study was conducted to evaluate the feed value and growth characteristics of Sasa quelpaertensis Nakai by horse grazing in the woodland of Jeju. Crude protein (CP), NDF, ADF and minerals contents at different growth stages of Sasa quelpaertensis were analyzed. The apparent digestibilities of DM, CP, NDF and ADF were determined by total collection method using 5 Jeju horses. The yield and growth characteristics of S. quelpaertensis Nakai by horse grazing were investigated. CP contents in the currentand the previous-year-sprouted leaves of S. quelpaertenisis were
, respectively. The digestibility of DM, CP, NDF and ADF in the current-year-sprouted leaves of S. quelpaertenisis were
, respectively. The current-year-sprouted S. quelpaertenisis tended to have high nutritional values and digestibilities compared to those of the previous-year-sprouted. The dry matter yield, plant length, leaf width and density of S. quelpaertensis Nakai were clearly decreased by horse grazing. These results show that considering the feed value and growth characteristics, the natural S. quelpaertenisis Nakai can be used as a feed source for horses.

This study was carried out to investigate the effects of by-product mixing silage feeding on the eating and ruminating behavior of fattening Hanwoo steer. A total of 12 Hanwoo steers (21 months old) were divided into three feeding groups and assigned to 3 dietary treatments: control (C: concentrate + ad libitum feeding of rice straw), and by-product mixing silage groups (T1: concentrate + 1 kg restricted feeding of by-product mixing silage + ad libitum feeding of rice straw, T2: concentrate + ad libitum feeding of by-product mixing silage). Eating behaviors were observed for 48 hours. Total feed intake was high in the order of T1 > C > T2, but not significantly different among the treatments. The eating and chewing time were significantly higher in C than by-product mixing silage treatments (P<0.05). Ruminating and resting time were not significantly different among the treatments. Number of bolus, number of total chews and number of chews per bolus were not significantly different among the treatments. But ruminating time per bolus and FVI (feed value index) were significantly higher in C than T1 and T2 (p<0,01, 0.05). Bolus per minute was the highest in T1 (p<0.01). Number of drinking was significantly higher in T2 than C and T1 (p<0.05), but defecating and urinating were not significantly difference among the treatments. Eating rate was the highest in T2 (p<0.05), but ruminating and chewing efficiency were not significantly difference among the treatments. Consequently, there was no big difference on eating behavior when feed by-product silage comparing with rice straw. Therefore, it is thought that by-product mixing silage could be the alternative for the rice straw.

The present study was conducted with four ruminally fistulated cattle to examine the fermentation characteristics and effective degradability (ED) in the rumen, and whole tract digestibility and TDN values of various silages (whole crop rye, RS; whole crop barley, BS; Italian ryegrass, IRGS and sudangrass, SGS) which were produced in Korea. The pH of rumen fluid were not greatly affected by silage at most times after feeding but SGS decreased (p<0.049) the ruminal ammonia-N concentration as 7.28 mg/100 ml at 3h after feeding compared to other silages. An acetate proportion from SGS feeding was higher at 1h (p<0.018), 3h (p<0.004) and 6h (p<0.019) after feeding than those from other silages. The propionate (
) proportion, however, was greater (p<0.001~p<0.042) for the RS and BS than the corresponding values of other silages up to 6h after feeding while the lowest
proportion was observed from SGS. The butyrate proportion was lowest (p<0.007~p<0.027) in the cattle fed BS at 1~6h after feeding among silages. An ED of dry matter (DM) in the rumen was highest (P<0.048) for RS as 59.64%, and was reduced in the order of BS (56.12%), IRGS (55.64%) and SGS (54.02%). Similar tendency was observed in the EDs of crude protein (p<0.014) and organic matter (OM, p<0.039). The whole tract digestibility of DM (p<0.032), neutral detergent fiber (NDF, p<0.034) and OM (p<0.041) of SGS was greatly reduced. The TDN value based on whole tract digestibility of silages was highest for RS as 61.1%, and TDN values of BS, IRGS and SGS were 57.1%, 57.9% and 50.7%, respectively. Based on the results obtained from the present study, components in various whole crop silages produced in Korea might affect the ruminal VFA proportion, and especially, NDF content could greatly influence on the TDN value of silage calculated based on the NDF content.

The experiment was conducted to observe the effects of dried whole crop barley treated with cellulolytic microorganisms (Aspergillus niger KCCM 60357 and Bacillus licheniformis KCCM 40934) on the chemical composition, in vitro colonic fermentation and whole tract digestibility in swine. Whole crop barley were fermented with no microorganism addition (control), A. niger, B. licheniformis and co-culture of A. niger and B. licheniformis (Mixture) for 3 days at
. In the feed chemical composition, CP contents of whole crop barley treated with A. niger (7.52%) and B. licheniformis (7.77%) were significantly higher than control (6.81%) (p<0.05). The in vitro colonic fermentation of dried whole crop barley fermented with control showed significantly higher
contents than A. niger, B. licheniformis and Mixture at 18h incubation (p<0.05). Dry matter (DM) digestibilities of A. niger (55%) and Mixture (57.42%) treatments were significantly higher than control (43.74%) (p<0.05). Ammonia-N was significantly increased in A. niger, B. licheniformis and Mixture relative to control at 24 hour incubation (p<0.05). Xylanase activities in A. niger, B. licheniformis and Mixture treatments were significantly higher than control at 24 hour incubation (p<0.05). Concentrations of total VFA were significantly increased in B. licheniformis (12.61 mM) at 24hour incubation (p<0.05). In vitro whole tract digestibility was significantly increased in B. licheniformis (49.61%) compared with the control (45.65%) (p<0.05). In conclusion, whole crop barley treated with cellulolytic microorganisms improved whole tract digestibility and colonic fermentation for swine.
