Soil fertility different depend on application rate of manure and compost for many years. While each crop has different adaptability depend on soil fertility, crop and species or varieties should be chosen depending on the adaptability and productivity. These experiments were carried out to compare the five winter cereal crops for whole crop silage on growth, yield and feed value as affected by soil organic content. The rate of increase on no. of spikes at high fertile soil compared with medium fertile soil was sequently high Samhan (Oat's variety) > Cheongwoo (Wheat) > Gogu (Rye) > Youngyang (Barley) > Shinyoung (Triticale). The rate of decrease at low fertile soil compared with medium fertile soil was sequently high Youngyang > Gogu > Cheongwoo > Shinyoung > Samhan. The triticale was lower variation of no. of spikes as affected by soil organic content than that of other winter cereals. The variations of dry matter yield as affected by soil fertility was higher oat and barley and lower triticale. Forage yield of triticale was higher about 69 percent than that of barley at low fertile soil. Forage yield was the highest in triticale and the lowest in rye in all soil fertility. In high fertile soil, rate of increasing digestible dry matter (DDM) yield compared with medium fertile was high in Samhan and Youngyang. Rate of reduced DDM yield in low fertile soil compared with medium fertile was low in Shinyoung and Cheongwoo.

This experiment was carried out to know adaptability, forage production and quality of corn hybrid for silage at paddy field at Chungnam region. Among agronomic characteristics, 'P32T83' hybrid was somewhat strong for waterlogging and good stay green, and low ear height as 57 cm and thicker stem diameter as 15.1 mm, and higher sugar content as 12 (Bo, %). The fresh and dry matter yield of 'P32T83' hybrid were the highest 55,220 kg/ha and 19,680 kg/ha, respectively. 'NC7117' hybrid was thicker as 15.5 cm and somewhat strong for waterlogging. The fresh and dry matter yield of 'NC7117' were 50,890 kg/ha and 19,110 kg/ha, respectively. The 'P32T83' hybrid was high as 81.9% in vitro dry matter digestibility (IVDMD). The result of this study indicated that 'P32T83' and 'NC7117' hybrid could be recommended as having good characters according to production, waterlogging tolerance, stay green, sugar content, and stem diameter at paddy field in Chungnam region.

This study was conducted to obtain basic a information on growth characteristics, productivity, and feed values of whole crop barleys with different awn types. The field experiments were conducted on land at Iksan, Jeollabuk-do province in Korea for one year. Six barleys with three different awn types, such as Youngyang (rough), Yuyeon (hood), Youho (hood), Iksan449 (hood), Iksan456 (hood), and Iksan448 (awnless), were used in this study. Barleys were harvested on five growth stages after (DAH); 20 days after heading (20 DAH), 25 DAH, 30 DAH, 35 DAH, and 40 DAH. Heading was earlier in Yuyeon (April 22), while was later in Iksan448 (April 29). The maximum dry matter and total digestible nutrients (TDN) yields, 11.8 and 8.1 ton per ha, respectively, was recorded in Ikan456 harvested at 35~40 DAH, followed by Youngyang, Yuyeon, Iksan448, Youho and the lowest in Iksan449. They were increased significantly with advancing crop maturity. Crude protein content was the highest in Iksan448 (10.9%) and the lowest in Youho (9.7%) and that was decreased significantly with late harvest. Total digestible nutrients (TDN) and relative feed value (RFV) were the highest in Iksan448 (73.0%, 183.8, respectively) and the lowest in Iksan456 (68.0%, 135.4, respectively) and they were increased significantly with late harvest. The mean RFV evaluated by awn types was the highest in Iksan448 (183.8) of awnless, the lowest in Youho (149.5) and Iksan456 (135.4), indicated the insufficiency of hooded type barleys as good fodder use. Therefore, in this study suggest that hooded barley should improve forage productivity as well as quality.

This study was carried out to determine the effect of seeding dates of Italian ryegrass interseeded into bermudagrass sod on the forage productivity and botanical composition of Italian ryegrass and bermudagrass. Experimental plot was located at 200 m altitude within Subtropical Animal Experiment Station, National Institute of Animal Science in Jeju from 2009 to 2010. Seeding date treatments of Italian ryegrass into bermudagrass sod were arranged in a randomized complete block design replicated three times. Italian ryegrass was drilled in row 20 cm apart after clipping the bermudagrass at a cutting height of 2~3 cm. Seeding time was on 15 September, 30 September and 15 October. The dry matter yield of Italian ryegrass was higher in 15 September seeding treatment, the dry matter yields of 30 September and 15 October seeding treatment were not different. The Italian ryegrass interseeded into bermudagrass sod didn't affect the dry matter yield in the summer harvests of bermudagrass, and the dry matter yield of bermudagrass showed the highest in August. In botanical composition, Italian ryegrass showed to reduced growth in early seedling stage after seeding by competition with bermudagrass, but Italian ryegrass was dominant to June increasing of temperature in spring next year and bermudagrass after Italian ryegrass harvests was dominant during summer season.

This experiment was carried out to find effective weed control method of henbit deadnettle (
L.) on cultivating field of Italian ryegrass (
Lam) using herbicide in Grassland and Forages Division, National Institute of Animal Science, RDA, Cheonan from 2008 to 2009. When Onehof was treated two times of spray, weed control ratio was most high as 90%, but this method can not be used because of much damage to Italian ryegrass. When MCPP was treated two times of spray, weed control ratio was high as 82%, and damage to Italian ryegrass was very insignificant. Especially, when the spray of MCPP was treated two times, dry matter yield of Italian ryegrass was 11,427 kg/ha, but that of non treatment was 1,658 kg/ha. That is to say, forage harvest was impossible in non treatment field. According to these results, to control henbit deadnettle on cultivating field of Italian ryegrass using herbicide, you need to treat with two times of spray of MCPP in mid-March. If you do, you can get regular harvest as much as 11,427 kg/ha.

This study was conducted to find out an alternative way of rapid and accurate analysis of forage quality. Near Infrared Reflectance Spectroscopy (NIRS) was used to evaluate the possibility of forage analysis. 175 samples consisted of Italian ryegrass, whole crop barley and pea seeded spring in 2009 were collected. The samples were analyzed for moisture, crude protein (CP), crude ash (CA), acid detergent fiber (ADF), and neutral detergent fiber (NDF), and also scanned using NIRSystem with wavelength from 400~2,500 nm. Multiple linear regression was used with wet analysis data for developing the calibration model and validated unknown samples. The important index in this experiment were SEC, SEP. The r2 value for moisture, CP, CA, ADF, and NDF in calibration set was 0.65, 0.97, 0.93, 0.99, and 0.97 and also was 0.15, 0.94, 0.96, 0.98 and 0.98 in validation set, respectively. The results of this experiment indicates that NIRS was reliable analytical method to assess forage quality for CP, CA ADF and NDF except moisture content in forage when proper samples incorporated into the equation development.

This study evaluated the feasibility of using a portable near infrared reflectance spectrometer working in the 900~1,600 nm range for the measurement of quality-related parameters (moisture, pH, Acid detergent fiber (ADF), Neutral detergent fiber (NDF), Crude protein (CP), lactic acid) in intact silage. The calibration result for the Phazir (handheld, Polychromix) was compared with the result for the Spectrastar (Lab. based, Unity). A total of 67 Italian ryegrass silages were used to build calibration models using different spectral signal pre-treatments and the partial least squares regression (PLS) method. The good calibration statistics in two instruments was obtained for moisture content of Italian ryegrass silages with over
= 0.95. The Phazir spectrometer was less accurate in measuring of ADF, NDF and CP contents. The Spectrastar instrument yielded greater precision for pH and lactic acid content; statistic values were over
= 0.82 and the standard error of calibration (SEC) = 0.21% and 0.24%. Thus, the NIR measurement of forage quality in the field by portable NIR analyzers was shown not to be feasible, but additional investigations are required to discern the key instrumental and operational parameters that may influence the portable NIR measurement.

This study was carried out to examine the nutritive values and quality of agricultural bag (AG-BAG) silage manufactured with corn grown in reclaimed paddy field of Sukmoon at Dangjin Province in Korea. The cultivars of silage corn used in this experiment 1 were both Kwangpyungok and P32B33. The fertilizer were applied with the amounts of customary applications (200 kg N/ha, 150 kg
/ha and 150 kg
/ha). The content of moisture in corn AG-BAG silage ranged from 68 to 79%. The pH in corn AG-BAG silage stages ranged from 3.49 to 3.65 and was not influenced by the harvest time. The contents of crude protein (CP) in corn AG-BAG silage decreased with delayed harvest time. However, the contents of ADF (acid detergent fiber) and NDF (neutral detergent fiber) increased. The content of lactic acid increased with delayed harvest time, but the content of acetic acid decreased. Therefore, we suggest that the system of AG-BAG silage can improve the quality of corn silage and be one of the economical and effective methods to manufacture corn silage.

DOI : 10.5333/KGFS.2011.31.4.431
This experiment was conducted to investigate the effects of molasses and
meal supplementation on the quality of Korean herbal medicine silage. Herbal medicine meal silages were produced by the addition of 0, 15, and 30% of
meal and 0, 1, and 2% of molasses (
factorial design) and stored for 40 days at room temperature. There were three replicates per treatment. Its quality such as chemical composition, pH, organic acids, the number of microorganisms and
dry matter disappearance were determined. As the
meal level increased, crude protein and crude fat contents increased significantly, but the acid detergent fiber (ADF) content decreased significantly. As the addition of
meal decreased, and molasses increased, pH tended to decrease, but the lactic acid content trended to increase. The acetic acid content was lower in a higher level (30%) of
meal, and higher in a higher level (2%) of molasses. As the
meal level increased, the butyric acid content decreased, and butyric acid of molasses treatment was higher than that of non-supplemented control. Molasses increased the number of Lactobacillus, but decreased the number of fungi in silage. A lower level of
meal increased the number of Lactobacillus, but decreased the number of fungi.
dry matter disappearance tended to increase by the addition of
meal and molasses. It is concluded that the addition of molasses and
to herbal medicine meal silage could enhance its nutritional quality. It is considered that proper levels of molasses and
meal in herbal medicine meal silage were 2 % and 15% respectively.

This study examined the effects of feeding whole-crop barley silage (BS), corn silage (CS) and the mixture of BS and CS (CB) on feed consumption, daily gain, nutrients apparent digestibilities and blood parameters in order to investigate the feed evaluation in Korean black goats. BS, CS, and CB were fed to twelve Korean black goats, which were allocated into three groups in metabolic cages according to the latin-square design. As a result, dry and organic matter intakes for goats per day have shown a tendency to decrease in the order of CS, CB and BS, but there were no significant differences. We also found a similar tendency when the intakes of crude protein, crude fat, and non-fiber carbohydrates (NFC) were examined. However, ADF and NDF consumptions showed a decreasing tendency in the order of CB, BS and CS. Dry matter intakes per metabolic body weight showed the decreasing tendency in the order of CS (57.6g), CB (53.8g) and BS (52.7g), however with no statistical differences. Average daily gain of 64.2 g in CB was significantly higher than the other groups (42.0g to 46.0g). Nitrogen intakes and nitrogen retention showed a decreasing tendency in the order of CS, CB and BC. Nevertheless, nitrogen retention in CS group was higher by 30% than that of the BC group with p<0.05. Apparant digestibilities of dry and organic matters were 72.6 and 72.8% for the CS group respectively, which were significantly higher than those of the BS group (67.5 and 69.0%) and the CB group (66.0 and 67.1%). In conclusion, the results of this study demonstrated that the CS group showed more positive feed consumption, digestibility, and nitrogen retention in Korean black goats than those of BS group. The CB group, however, showed similar results to the results of the CS group.

The purpose of this study was to investigate fungi and mycotoxin contamination of the rice straw bale silage in Korean. It was tested the 33 samples of rice straw round bale silage with various condition which fed cattle in the farm. The level of fungal contamination was
in the average and
in the maximum. The fungal contamination was detected in the all of normal samples which good condition of rice straw bale silage. When the fungi was isolate and identify, it was found 28 species and mycotoxin producing fungi were 8 species as following as Aspergillus flavus, Aspergillus fumigatus, Fusarium culmorum, Fusarium verticillioides, Penicillium carneum, Penicillium paneum, Penicillium roqueforti, Penicillium viridicatum. Specially, Penicillium paneum was found 42% of samples and Aspergillus sp. (A. flavus, A. fumigatus) are 21% of samples. In case of mycotoxin contamination, the 42% of samples are detected more than one kind of mycotoxin. Some samples are contaminated three kinds of mycotoxin. This study was not found aflatoxin (
) and fumonisin (
), but were detected the contamination of ochratoxin A (1.0~5.8 ug/kg), deoxynivalenol (DON, 156.0~776.7 ug/kg) and zearalenone (ZON, 38.0~750.0 ug/kg). Therefore, the above results show that rice straw round bale silage expose on hazard factors as mycotoxigenic fungi and mycotoxin contamination, and than need more research about mycotoxin in animal feed to protect animal and human healthy.
