Abstract

The aim of this study was to evaluate the chemical composition, in vitro 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 (p < 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 (p < 0.05) and produced lower amounts of ammonia-N (p < 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 in vitro study. The results showed that PP8R2 and WP7R3 had higher (p < 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 (p < 0.05) for the goats and the Hanwoo cattle, whereas PP8R2 had the highest (p < 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.

干柿子（Diospyros kaki）副产品作为反刍动物饲料来源的潜在用途。

本研究的目的是评估干柿子副产品（柿子皮[PP]和受损的整柿子[WP]）与稻草按不同混合比例混合后的化学成分、体外消化率和适口性。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）的比例混合腌制 70 d。与其他组合相比，WP3R7 的粗蛋白和乳酸盐含量最高（p < 0.05）。另一方面，PP3R7 和 PP8R2 的中性和酸性洗涤纤维含量较低（p < 0.05），产生的氨氮量较低（p < 0.05）。在体外研究中，将这些青贮饲料与稻草青贮饲料（RS）、玉米青贮饲料（MS）、全茬黑麦青贮饲料（WCRS）和高粱-苏丹草青贮饲料（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（p < 0.05）高于 RS、MS、WCRS 和 SSGS。此外，还采用食堂法对汉乌牛、山羊和鹿进行了青贮适口性测试。山羊和韩宇牛对 PP7R3 的适口性指数最高（p < 0.05），而鹿和韩宇牛对 PP8R2 的适口性指数最高（p < 0.05）。总之，以 PP 和 WP 形式存在的干柿子副产品与 RS 按 7:3 和 8:2 的比例混合后，可用作反刍动物饲料。

期刊介绍： Journal of Animal Science and Technology (J. Anim. Sci. Technol. or JAST) is a peer-reviewed, open access journal publishing original research, review articles and notes in all fields of animal science. Topics covered by the journal include: genetics and breeding, physiology, nutrition of monogastric animals, nutrition of ruminants, animal products (milk, meat, eggs and their by-products) and their processing, grasslands and roughages, livestock environment, animal biotechnology, animal behavior and welfare. Articles generally report research involving beef cattle, dairy cattle, pigs, companion animals, goats, horses, and sheep. However, studies involving other farm animals, aquatic and wildlife species, and laboratory animal species that address fundamental questions related to livestock and companion animal biology will also be considered for publication. The Journal of Animal Science and Technology (J. Anim. Technol. or JAST) has been the official journal of The Korean Society of Animal Science and Technology (KSAST) since 2000, formerly known as The Korean Journal of Animal Sciences (launched in 1956).
