| 中文摘要 | 本研究之目的是透過營養分、消化率及農業性狀之量測,確認狼尾草台畜三號之最佳 割期與留樁高度。試驗割期分別為 30 天、60 天與 90 天,留樁高度分別為 10 公分與 20 公 分。試驗結果顯示,粗蛋白質含量隨著割期之延長有降低的趨勢,中洗纖維、酸洗纖維與可 溶性碳水化合物之含量從 30 天延長到 90 天則是顯著提高。試管乾物質消化率與真消化率皆 隨著割期之延長而降低。留樁高度 10 公分或 20 公分對於狼尾草台畜三號的影響不顯著。綜 合上述結果,推薦 60 天為狼尾草台畜三號之最佳收割間距。 |
| 英文摘要 | The aim of the research was to investigate the different cutting intervals and stay heights on the nutritive content, digestibility and agronomic traits of the cultivar NP cv. TS3 of Napier grass (Pennisetum purpureum) (NP cv. TS3). Treatments were cutting intervals of 30, 60 and 90 days, and stay heights with 10 and 20 cm. The results showed that the crude protein (CP) content had a downtrend as the cutting intervals were extended from 30 to 90 days, while contents of neutral detergent fiber (NDF), acid detergent fiber (ADF) and water soluble carbohydrates (WSC) showed the rising trend, significantly. The in vitro dry matter digestibility (IVDMD) and in vitro true digestibility (IVTD) of the grass decreased as the cutting intervals were prolonged. No significant (P > 0.05) difference was observed between the cutting heights 10 and 20 cm of the NP cv. TS3 for the cutting intervals at 30, 60 and 90 days. The results suggested that the cutting intervals of 60 days might be the optimum for good forage quality of the NP cv. TS3 in Taiwan. |
