中文摘要 | 本省北部地區於4~5月初春及9~11月晚秋季節,盤固草不適於用來調製乾草,分 別於草高60、80、100公分時收割,利用圓柱型打包機將盤固草打包,並以膠膜捆紮後貯存, 製作半乾青貯料,以探討不同割期之盤固草調製半乾青貯料品質比較。 於秋季收割盤固草,如延遲至80公分高度方才收割,所獲乾物量雖較高,然粗蛋白質(CP) 含量已大幅下降,酸洗纖維(ADF)含量增加,乾物質試管消化率(IVDMD)亦降低,顯示牧草已老 化,品質下降。春季生長之盤固草則以草高80公分收割時,乾物產量較高,品質亦佳,故盤 固草若用作青飼或供製乾草時,在秋季應於草高60公分左右時收割,春季則於草高達80公 分左右時收割較為適宜,但若以調製半乾青貯料方式利用時,則延遲收割之芻料品質較不受影 響,於春季延遲至草高達100公分收割可獲乾物產量較高、青貯料評分較佳之趨勢。 |
英文摘要 | The objective of this study was to investigate the effects of cutting season and cutting height on the haylage quality of pangolagrass ( Digitaria decumbens). In the early spring and late autumn, grasses were cut when the plant height reached 60, 80 and 100 cm, respectively. Then, grasses were baled and wrapped with polyethylene film. The outdoor stored haylage bales were sampled after 3 months. The chemical composition of the haylage include crude protein (CP), acid detergent fiber (ADF), in vitro digestibility (IVDMD) and some organic acids, were determined. The results showed that it was better to harvest the grass when the plant height were 80 and 60cm in early spring and late autumn season, respectively. More forage and better quality could be obtained while pangolagrass was harvested for soiling or hay making. However, if the grass harvest was delayed by some climatic reasons, the harvest effect on forage quality was smaller for haylage making than for hay making in both seasons. |
