研究了东亚常见根茎蔬菜白萝卜（萝卜）副产品青贮作为一种可行的保存方法和潜在的动物饲料资源。进行了两个单独的实验：第一个实验涉及白萝卜的化学和一些内在的预青贮特性的研究，作为白萝卜副产品青贮的前导。首先以麦秸为唯一吸附剂，接种或不接种植物乳杆菌（Lactobacillus plantarum， LP），调节白萝卜副产物的高水分含量，并在青贮1 d后监测青贮发酵产物和微生物发育情况，研究6 d后的好氧稳定性。第二项试验研究了用干甜菜浆、豆茎、豆壳和麦麸作为备用的仓内污水吸收剂，然后进行青贮采食量和绵羊偏好试验。虽然用或不用LP青贮白萝卜可以产生发酵良好的青贮，但主要的限制是高流出物产量和随之而来的营养损失；与干燥材料混合是青贮保存的必要条件。好氧处理4 d后青贮保持稳定，5 d后青贮开始变质，特别是添加麦秸吸收剂的白萝卜青贮。麦秸对废水的截留能力最强，其次是豆茎和豆皮，其次是干甜菜浆，麦麸对废水的截留能力较差。干甜菜浆/白萝卜混合青贮的采食量和偏好最好。(c) 2006 Elsevier B.V.版权所有
Ensiling of the by-product of daikon or Oriental radish (Raphanus sativus), a popular root vegetable in East Asia, as a viable preservation method and potential animal feed resource was investigated. Two separate experiments were carried out: the first involved a study of the chemical and some intrinsic pre-ensiling characteristics of daikon as a prelude to ensiling of daikon by-product. The high moisture content of daikon by-product was adjusted first with wheat straw as a sole absorbent and inoculated with or without Lactobacillus plantarum (LP), a lactic acid culture, the monitoring of fermentation products and microbial development in the silages with days in ensilage and the study of the aerobic stability after 6 days. The second investigated the use of dried beet pulp, bean stalks and husks and wheat bran as alternate in-silo effluent absorbents followed by silage intake and preference test with sheep. While ensiling daikon with or without LP produced well fermented silage, a major limitation is the high effluent production and consequent nutrient losses; incorporation with dry materials is sine qua non for its preservation by ensilage. Silages were stable after 4 days of aerobic exposure but began to deteriorate after 5 days especially with daikon added with the wheat straw absorbent. Wheat straw retained effluent most followed by bean stalks and husks, and dried beet pulp in that order, while wheat bran showed poor effluent retention capacity. Dried beet pulp/daikon mixture silage was best in terms of feed intake and preference. (c) 2006 Elsevier B.V. All rights reserved.
