  • Various extracts of higher plants have been used in traditional medicine systems for centuries. While tropical and sub-tropical plants have received considerable attention from the researchers for evaluation of their bioactivity, temeperate plants have always been neglected somewhat. Similarly, seeds of the plants have not been considered seriously compared to other plant parts, e.g. leaves, stems, roots, flowers, etc. as a potential source for biologically active compounds. As part of our on-going evaluation of the extracts of the seeds of temperate plants, especially from Scotland, for biological activity, Achillea millefolium, Angelica sylvestris and Phleum pratense have been chosen for the present study. Both A. millefolium and A. sylvestris are well known for their traditional medicinal uses in Europe and also in the orient, but there is no report on any medicinal properties of P. pratense available to date. Extracts of the seeds of these plants have been assessed for their antioxidant and antibacterial potential and also for general toxicity. Both DCM and MeOH extracts of A. millefolium showed the most significant broad spectrum antibacterial activity among the three plants and inhibited the growth of almost all test strains of bacteria. The DCM extracts of all three species were active against methicillin resistant Staphylococcus aureus (MRSA) and Citrobacter freundii $(MIC=6.25{\times}10^{-1}\;mg/mL)$. While the MeOH extracts of A. millefolium and P. pratense were active against C. freundii, that of P. pratense was also active against MRSA. The MeOH extract of A. sylvestris did not show any antibacterial activity against any of the eight bacterial strains at test concentrations. The MeOH extract of P. pratense showed the most prominent antioxidant activity $(IC_{50}=145\;{\mu}g/ml)$ and there was no antioxidant activity observed with the DCM extract of A. millefolium. The DCM extract of P. pratense was the most toxic $(LC_{50}=20\;{\mu}g/ml)$ among the extracts.

  • To find out the nutrient contents of temperate grasses on the south and north slope, a field experiment was conducted with five forage species of Dactylis glomerata, Festuca arundinacea, Phleum pratense, Agrostis gigantea and Trifolium repens. It was treated by randomized block design with 4 replications and lasted from September, 1983 to October, 1986 in Suweon. The results obtained are summarized as follows: 1. Mean chemical compositions except NFE and crude fiber of the forage species on the south slope were a little more contented than that of north. But all crude components were significant difference among the species on the south and north exposure. 2. Production of TDN (total digestible nutrient), StE (starch equivalent) ME (metabolizable energy) and NEL (net energy lactation) of different grass species on the north slope were much more increased by 5-30% per ha (Dactylis glomerata by 5-876, Festuca arundinacea by 5%, Phleum pratense by 24-26% and Agrostis gigantea by 25-30%) than that of same grasses on the south, however, those of Trifolium repens were much more increased by 4 1-42% per ha in the south. 3. Mineral contents, Ca/P ratio and K/ (Ca + Mg) equivalent ratio of the species were slightly different between the exposures. But considering the factors of occuring grass tetany, those of the forage species on the north slope were better than that of same species on the south.

  • This study was undertaken to evaluate the effect of legume reseeding on legume establishment, dry matter yield, quality and botanical composition of grasses in timothy(Ph1eum prarense L.) dominated pasture at alpine area. Establishment number and percentage of legume in timothy dominated pasture were increased with spring, red clover(Tr$olium pratense L.) and gramoxone $treatment Dry matter yield of pasture was increased with fall and grazing after overseeding, but, there waq no difference in legume species. Crude protein content(%) of grasses at the first cutting was increased with red clover and paraquat (gramoxone) treatment. Based on the results, it is suggested that spring in seeding time, red clover in legume species and oveneeding after gramoxone treatment are good for effective renovation of timothy dominated pasture at alpine area.

  • This experiment was carried out in laboratory to find out the effect of coating materials, minerals and insecticides on germination of pasture seed. Seed coating was made by specially made machine and seed germination in petridishes was also determined from Sep. 1986 to May 1987. The results were summarized as follows; 1. Coating seed gave bad germination compared with the control. There were significant difference between treatment, coating materials and adhesives in white and red clover while Phleum pratense germination was improved by coating materials. 2. In mineral coating treatments, on Mg alone or Mg mixed treatment, germination was deepressed. Generally germination was lowed by mineral treatment, but the difference was small. 3. Uncoating treatment with insecticide was superior to coating treatment in terms of germination. Among the insecticide Ballen gave more serious effect to seed germination.

  • The aim of this study was to collect the basic data for effective creation and management of hilly pasture. The investigation of flora and vegetation was conducted at 59 $relev\acute{e}s$ in hilly pasture of Daegwallyeong from 2014 to 2016. The vascular plants of the hilly pasture were 121 listed taxa which contain 38 families, 90 genera, 104 species, 13 varieties, and 12 subspecies. The biological type of the hilly pasture was determined as the $Th-D_4-R_5-e$ type. Twelve taxa were of naturalized plants composed of 5 families, 9 genera, 12 species. The urbanization index and the naturalized index were 3.7% and 9.9%, respectively. The vegetation types in the hilly pasture were classified into the following 3 communities: the Spiraea miyabei-Spiraea salicifolia community, the Persicaria thunbergii community, and the Agrostis alba-Phleum pratense community. The Agrostis alba-Phleum pratense community was classified into the following 5 subcommunities: the Poa pratensis subcommunity, the Artemisia princeps subcommunity, the Festuca ovina subcommunity, the Rumex acetosella subcommunity, and the typical subcommunity. Two factors (slope and EC) had the strongest impact on plant community distribution. Especially, the steep sloping sites (over $40^{\circ}$) did not play a crucial role in maintaining adequate pasture because of the invasion and establishment of shrubs.

  • To find out the productivity of temperate grasses on the south and north slope, a field experiment was conducted with five forage species of Cactylis glomerata, Festuca arundinacea, Phleum pratense, Agrostis gigantea and Trifolium repens. It was treated by randomized block design with 4 replications and lasted from September, 1983 to October, 1986 in Suweon. The results obtained are summarized as follows: 1. During the vegetative period for three years, the mean surface temperature and soil temperature at a depth of lOcm on the south exposure were 2.0^{\circ}C$ and 0.8^{\circ}C$ respectively higher than that of north slope, but the soil temperature between exposures were practically not different in the mid-summer season. 2. Early growth and development of forage species on the north exposure were better than that of species on the south slope. 3. Average DM yield of grasses on the north slope was much more increased than that of species on the south, however, Trifolium repens was more positive in the south. 4. Otherwise average DM yield of Dactylis glomerata and Festuca arundinacea on the north slope was a little more increased, that of Phleum pratense and Agrostis gigantea was much more increased than that of same forage species on the south.

  • The ruminal solubility of copper (Cu), manganese (Mn), molybdenum (Mo), and zinc (Zn) in eight Philippine forages was studied. These forages were: 1) grasses: paragrass (Brachiaria mutica (Forsk.) Stapf), stargrass (Cynodon plectostachyum Pilger), and napiergrass (Pennisetum purpureum Schumach.); 2) creeping legumes: calopogonium or calopo (Calopogonium muconoides Desv.) and centrocema (Centrocema pubescens Benth.); 3) tree lequmes: gliricidia or kakawate (Gliricidia sepium (Jacq.) Walp.), leucaena or ipil-ipil (Leucaena leucocephala (Lam.) de Wit.), and sesbania or katuray (Sesbania grandiflora (L.) Poir). Nylon bags with samples were incubated for 0, 3, 6, 12, 24, 48 and 72h in three rumen cannulated sheep fed with timothy hay (Phleum pratense L.) at 2% body weight/d. The 0-h bags were washed with deionized water. There were species differences (p < 0.05) on the different solubilities of trace elements. At O-h incubation, the trend of solubility was Mo (54%) > Zn (43%) > Cu (38.7%) > Mn (29.5%). At 3-h incubation, all the elements except Mn had an average solubility above 50%. Combining particulate passage rate (1.9%/h) and various trace elements disappearance rates, the effective ruminal solubilization (ERS) of trace elements were computed. The ERS across species ranged from 44.6 to 89.9% for Cu, 29.9 to 84% for Mn, 66 to 95.1% for Mo, and 30.1 to 82.3% for Zn resulting to a trend of Mo > Zn > Cu > Mn.

  • Forage quality evaluation with several grasses grown at a high altitude pasture situated at 1,000m above sea level was made to determine what is the feed value of these grasses and whether these grasses have any differences in forage quality compared with the grdsses grown at lowland pastures. In this experiment, Common, Venture, and Palaton reed canarygrass (Phahris arundinucea L.) and Climax timothy (Phleum pratense L.) were used and harvested at two different dates, 5 July and 30 September, 1989. Cmde protein (CP) concentrations in the grasses grown in September were higher than in July. Among the grasses grown, Palaton and Common reed canarygrass were highest in CP concentration in July and September, respectively. Acid detergent fiber (ADF) and neutral detergent fiber (NDF) concentrations in the grasses harvested in July were higher than in September. Palaton reed canruygrass was lowest in ADF and NDF concentrations at the both harvest dates. Relative feed value (RFV) in the grases harvested in July was ranged from 92 to 105 and that in September was from 110 to 117. Palation reed canarygrass had the highest RFV of 105 and 117 in July and September, respectively, therefore, the forage quality of this grass was ranked as Grade 2 based on the AFGC Hay Quality Standards. Overall forage quality of the grasses grown at a high altitude pasture seemed to be higher than the forage quality at lowland pastures. Based on the RFV assigned by the AFGC, forages with RFV 92 to 117 in this experiment could only work well in rations for low producing dairy cows.

  • The effects of inorganic selenium (Se), selenate and selenite on Se balance levels in the different ruminal fluid fractions were studied using Japanese Corriedale wethers with an average body weight of 47 kg. A $3{\times}3$ Latin square design was used with three animal, three periods and three treatments. In each period, there was 7 d dietary adjustment followed by 5 d total collection of urine and feces. Ruminal fluid samples were obtained at 0, 1, 3, 5 and 7 h postprandially on the final day of the collection period. The three dietary treatments were: (1) without Se supplementation (control); (2) with Se supplement as sodium selenate; and (3) sodium selenite at a rate of 0.2 mg Se/kg dietary DM. The basal diet was timothy hay (Phleum pratense L.) fed 2% of body weight/d. Results indicated that Se balance were higher (p < 0.05) for those animals under supplementation than those animals under control. Overall data gathered showed a similar digestion balance of selenate and selenite in sheep. Inorganic Se, both selenate and selenite produced positive Se contents of the ruminal feed particles and protozoa. Bacterial Se increased (p < 0.05) on the first three hours post-prandially in Se supplemented diets. Gross ruminal fluid fraction, although there was improvement on their Se content under the supplemented diets, the changes were insignificant over the control. free inorganic Se and Se in soluble protein of the ruminal fluid were not significantly different for selenate and selenite. Most of the Se in the ruminal fluids of the animals under supplementation were insoluble, indicating the influence of rumen environments on Se bioavaliability.
