摘要
为了满足繁殖期水貂对于微量元素、矿物质元素、维生素等营养物质较高的需要,使各种营养性添加剂与饲料均匀混合,便于生产中饲喂操作,开发了新型、实用性水貂饲料预混料(商品名水貂伴侣饲料,由沈阳双良饲料有限公司生产),将膨化玉米与各种矿物质、微量元素及维生素按照一定比例混合,外加金霉素、胆碱等配制而成。选择健康、成年繁殖期水貂45只,分为3组,每组15只,分别饲喂伴侣饲料1、2、3。并且探讨了伴侣饲料与新鲜饲料的配制比例,分别以10%和20%的比例将伴侣饲料添加到水貂鲜饲料中,比较了采食量和粗蛋白质消化率。试验结果表明,饲喂新型水貂伴侣饲料的水貂采食正常,体增重与对照组相比差异不显著(p>0.05),试验组排便正常,添加恩拉霉素和金霉素组粪便更趋向于条状。饲喂该伴侣饲料不仅促进水貂生长,促进粪便成型,还在一定程度上便于预混料与饲料混合均匀,一定程度上能节约了劳动力成本。添加的适宜比例推荐为20%。
In order to meet the reproductive period of mink in trace elements, minerals, vitamins and other nu.trients. To make all kinds of nutritional additives and feed mixed and convenient operation. Development of new, practical mink feed premix. The extruded corn and various minerals, trace elements and vitamins are mixed according to a certain proportion plus aureomycin, choline and prepared. Forty-five healthy American male minks inreproductive period were randomly divided into 3 groups with 15 replicates. The minks in 3groups were fed with additives 1(groupⅠ), additives 2(groupⅡ)and additives 3(groupⅢ)respectively.Additives were added to fresh feed mink by 10% and 20% proportion respectively. The feed intake and digest.ibilities of crude protein were prepared in two groups. The body weight gain of minks were similar in two pro.portion groups. The appropriate proportion is 20%.
