摘要

狼尾草品系7768係由親本珍珠粟Tift85 DB與狼尾草Mott人工授粉雜交後裔族群中選育成之優良品系，經區域試驗、栽培管理試驗及動物試驗等，顯示品系7768之牧草品質優於對照品種NPcv.TS3，其植物體之粗蛋白質（crude protein, CP）12.0%高於NPcv.TS3的10.8%，酸洗纖維（acid detergent fiber, ADF）及中洗纖維（neutral detergent fiber, NDF）分別為31.8%及60.7%，比NPcv.TS3之33.2%及60.9%低。品系7768之鮮草產量為130.2 mt/ha/year比NPcv.TS3低。乾物質消化率（in vitro dry matter digestibility, IVDMD）與NPcv.TS3相近（68.2 vs. 68.3%），兔之動物試驗顯示其採食量與血液生化值與餵飼提摩西草（Phleum pratense）之結果相近。狼尾草品系7768已於2015年5月通過新品種命名登記審查，並命名為狼尾草臺畜草六號（NPcv.TS6）。

Napiergrass (Pennisetum purpureum) line 7768 is one of the progeny of Tift85 DB (pearl millet) crossed with the line Mott of napiergrass. Those were based on a series of test, including progeny selections, regional yield trial, culture managemental trials and animal feeding trials. Results showed that 7768 possed more crude protein (12.0% vs. 10.8%) and less of acid detergent fiber (31.8% vs. 33.2%) and neutral detergent fiber (60.7 vs. 60.9%) compared with check NPcv.TS3. In the regional yield trials, the average hay production of line 7768 was 130.2 ton/ha/year lower than that of NPcv.TS3. No significantly difference between line 7768 and NPcv.TS3 on in vitro dry matter digestibility (IVDMD) value. There was also significantly different of hay feeding trial and parameters of blood analysis between feed with Timothygrass (Phleum pratense) and line 7768 by rabbits. Line 7768 was renamed as Napiergrass Taisu No.6 (NPcv.TS6) in 2015.
