摘要
西班牙评估了葡萄荚(Acacia macracanta,AM)中二级化合物的减毒作用,以供兔子配给(Oryctolagus cuniculus mestizos California x New Zealand)使用。试验1:完全随机的因子排列、浸泡温度因子(25、45和65°C)和水浸泡时间因子(0、6、12、24和48小时)。试验2:通过评估基础日粮(生蛋白183 g.kg-1和NDF 467 g.kg-1,玉米和豆粕、百慕大干草、豆油、矿物质和氨基酸的混合物)和含有30%减毒AM和可变数量基础原材料(生蛋白184 g.kg-1和NDF 511 g.kg-1)的日粮,确定消耗量、消化率和体重增加。每处理12只兔子(体重969±48.7克,年龄55天)。经过7天的适应期,记录了62至89天的食物消耗和粪便收集。在第一项试验中,最有效的二级化合物的减少是在65°C下浸泡AM鞘48小时。初始含量的减少为:总多酚72.4%,单酚82.1%,总单宁63.3%,浓缩单宁90.8%,沉淀蛋白质单宁74.5%。在试验2中,AM配给的食物摄入量更高(128 vs 107 g.d-1,p English)对Uveda Pods(Acacia macracantha,AM)中二级化合物的衰减进行了评估,以评估其在兔子配给中的潜在用途(Oryctolagus cuniculus mestizos California x New Zealand)。测试1:完全随机的因子排列、浸泡温度因子(25、45和65°C)和浸泡时间因子(0、6、12、24和48小时)。测试2:通过评估基线比率(粗蛋白183 g.kg-1和NDF 467 g.kg-1,玉米和大豆混合物,百慕大海伊,大豆油,矿物质和氨基酸)以及含有30%衰减AM和不同数量基础原料(粗蛋白184 g.kg-1和NDF 511 g.kg-1)的服务来确定消耗量、消化率和体重增加。每种处理使用12只兔子(活重969±48.7 g,年龄55天)。在7天的适应期之后,记录了食物摄入量,并收集了62至89天的日期。从第一次审判开始,最有效的二次复合还原是在65°C下将AM播客浸泡48小时。初始含量减少为:总多酚72.4%,单酚82.1%,总鞣质63.3%,浓缩鞣质90.8%,沉淀蛋白质的鞣质74.5%。在试验2中:AM定量的食物摄入量更高(128 vs 107 g.d-1,p
