摘  要：
用三种饲粮类型(玉米-豆饼,即全豆饼型,含锰17毫克/千克;玉米-1/2豆饼蛋白-1/2菜籽饼蛋白,即1/2菜籽饼型,含锰21毫克/千克和玉米-1/2豆饼蛋白-1/2棉仁饼蛋白,即1/2棉仁饼型,含锰14毫克/千克)与三个无机锰(试剂级一分子结晶水硫酸锰)添加水平(0.60和120毫克/千克)作3× 3析因设计,将288只一日龄ArborAcres(AA)雏鸡(公母各半)分成9组,试验28天,研究不同类型饲粮中的天然锰及添加的无机锰的生物学有效性影响。结果表明,以跖骨灰锰等组织锰含量指标测得三种类型的饲粮中天然锰的有效性无明显差异;以跖骨灰锰的线性及多元线性回归斜率和锰含量平均增加计算,设无机锰在全豆饼型饲粮中的有效率为100.0%,则在1/2菜籽饼型和1/2棉仁饼型饲粮中的相对有效率分别为70.5%和107.8%。

摘  要：
A trial was conducted using 288 day-old Arbor Acres (AA) broilers (half male, half female) in a replicate 3×3 factorial arrangement of treatments involving three types of diets (eorn-SBM, i. e. SBM type, containing 17mg Mn/kg; corn-1/2 SBM protein-1/2 RSM protein, i. e. 1/2 RSM type, containing 21mg Mn/kg and corn-1/2 SBM prorein-1/2 CSM protein, i. e. 1/2 CSM type, containing 14mg Mn/kg) and three levels of added inorganic Mn (reagent grade MnSO_4' H_20) (0.60 and 120mg/kg) for 28 days to investigate the effects of RSM and CSM on bioavailability of feed Mn and added Mn in the diets of broiler chicks. Without Mn supplementation, Mn contents in metatarsal bone ash, liver and pancreas were higher (P<0.01) in 1/2 RSM type than in the other two types with a slightly higher (P>0.05) tissue Mn in SBM type than in 1/2 CSM type; As dietary Mn levels increased, Mn contents in the above mentioned tissues were linearly increased (P<0.05 or 0.01) for all three types of diets. Based on linear and multiple linear regression slopes and increase in metatarsal bone ash Mn content, relative bioavaliability of added Mn in 1/2 RSM type diet and 1/2 CSM type diet averaged 70.5% and 107.8% if 160.0% was set for SBM type diet. These results suggested that there was no difference in feed Mn bioavailability among three types of diets, however 1/2 RSM type diet reduced the relative bioavailability of added inorganic Mn by about 30%
