     概要を見る

    This experiment was carried out to examine the seasonal change of several kinds forage grass and wild grass of litter decomposition rate in subtropical native pasture on the grassland ecosystem.The litter of the above-ground used for the experiments is standing dead plants of Bidens pilosa, silver grass, pangolagrass, bahiagrass collected in the previous year. A standing dead plant as litter materials was divided lamina part and stem part, and used three grass species Bidens pilosa, silvergrass, pangolagrass. Litters that range from 4 to 7 grams of each grass put in the litter bag were set in grassland. Setting litter bags in grassland were picked up every other month. There was a significant difference on the average litter decomposition rate of three grasses which are Bidens pilosa, silver grass and pangolagrass though it showed the similar tendency in seasonal changes of the litter decomposition rate of the above-ground. It was quicker decomposition rate than litter decomposition rate of the above-ground of each grass species than that of the stem, though there was one exception in pangola grass species which lamina parts were low value than stem parts from July through September. Litter decomposition rate of the lamina parts of Bidens pilosa and silvergrass were significantly faster than that of stem parts, but was not significant litter decomposition rate between lamina and stem parts of pangolagrass. There was positively correlated with difference of litter decomposition rate between lamina part and the stem parts of which were Bidens pilosa, silvergrass and pangolagrass. There was positively correlated with difference of litter decomposition rate between digestability of used grasses. It is necessary to sufficiently consider for the decomposition rate of the litter, when it constructs the simulation model by carrying out systems analysis, since it significant change in the every season.

     概要を見る

    This study was conducted to investigated the methods of continuous body temperature determination in grazing Japanese Black cattle. The relationships of body temperature with grazing behavior of cattle and also diurnal change in body temperature were analyzed. Seven Japanese Black cattle, 334 kg of average weight, were grazed on dominant pastue of Paspalum conjugatum Berg and Bidens Pilosa L.var. radiata Scherff. A cow 380 kg of body weight was selected and carried out four times during from january from December. Body temperature of cow was determined in which two thermo-recoder inserted the rectum and vagina. It were found that continuous determination of diurnal temperature of cow under grazing at one minute interval for 24-hour was successful when thermistor was inserted into the vagina of cow. Diurnal changes of vaginal temperature were showed circadian rhythm, being lowest at 10:00 and highest at 20:00. Body temperature of cow increased when the animal lied down and returned to the normal after standing up. It were made known that vaginal temperature of grazing cow has gone up, and gone down in standing. (管理者追加)リポジトリ登録情報を移行しました。確認のうえ、加除修正をしてください。
