The aim of this study was to evaluate the chemical composition, digestibility, and palatability of dried persimmon byproducts (persimmon peel [PP] and damaged whole persimmons [WP]) ensiled with rice straw in different mixing ratios. PP and WP were ensiled with rice straw at ratios of 3:7 (PP3R7, WP3R7), 5:5 (PP5R5, WP5R5), 7:3 (PP7R3, WP7R3), and 8:2 (PP8R2, WP8R2) for 70 d. WP3R7 had the highest ( < 0.05) crude protein and lactate contents compared to the other combinations. On the other hand, PP3R7 and PP8R2 had lower concentrations of neutral and acid-detergent fibers ( < 0.05) and produced lower amounts of ammonia-N ( < 0.05). The silages were compared to rice straw silage (RS), maize silage (MS), whole-crop rye silage (WCRS), and sorghum-sudangrass silage (SSGS) during an study. The results showed that PP8R2 and WP7R3 had higher ( < 0.05) dry matter digestibility values than RS, MS, WCRS, and SSGS in a 6 h incubation period. In addition, a palatability test of the silages was conducted on Hanwoo cattle, goats, and deer, using the cafeteria method. The palatability index rate of PP7R3 was the highest ( < 0.05) for the goats and the Hanwoo cattle, whereas PP8R2 had the highest ( < 0.05) rate for the deer and the Hanwoo cattle. In conclusion, dried persimmon byproducts in the form of PP and WPs can be used as ruminant feed when ensiled with RS at ratios of 7:3 and 8:2.
本研究的目的是评估以不同混合比例与稻草青贮的柿饼副产品（柿皮[PP]和破损的整柿[WP]）的化学成分、消化率和适口性。将PP和WP与稻草按3:7（PP3R7、WP3R7）、5:5（PP5R5、WP5R5）、7:3（PP7R3、WP7R3）和8:2（PP8R2、WP8R2）的比例青贮70天。与其他组合相比，WP3R7的粗蛋白和乳酸含量最高（P<0.05）。另一方面，PP3R7和PP8R2的中性洗涤纤维和酸性洗涤纤维浓度较低（P<0.05），氨氮产生量也较低（P<0.05）。在一项研究中，将这些青贮饲料与稻草青贮（RS）、玉米青贮（MS）、全株黑麦青贮（WCRS）和高粱-苏丹草青贮（SSGS）进行了比较。结果表明，在6小时的培养期内，PP8R2和WP7R3的干物质消化率值高于RS、MS、WCRS和SSGS（P<0.05）。此外，采用自助餐厅法对韩牛、山羊和鹿进行了青贮饲料的适口性测试。PP7R3对山羊和韩牛的适口性指数率最高（P<0.05），而PP8R2对鹿和韩牛的适口性指数率最高（P<0.05）。总之，PP和WP形式的柿饼副产品在与RS按7:3和8:2的比例青贮时可用作反刍动物饲料。
