摘　　要：用24头已与杜洛克父本配种的妊娠70天的(长×大)杂交母猪及其所生的24窝仔猪进行试验,研究不同铁源与注射铁剂补铁对新生和哺乳仔猪铁营养状况的影响。试验分为妊娠和泌乳两个阶段,均采用完全随机设计。在妊娠阶段,将妊娠70天的杂交母猪24头随机分为3个处理组,分别饲喂添加80mg/kg铁源于硫酸亚铁的玉米 豆粕 小麦麸型饲粮(正对照组)和在正对照组饲粮基础上添加120mg/kg铁源于氨基酸铁络合物的饲粮(有机铁组),以及在正对照组饲粮基础上添加120mg/kg铁源于硫酸亚铁的饲粮(无机铁组)。在泌乳阶段,泌乳母猪继续饲喂以上妊娠母猪的相应处理饲粮,而对来源于以上24头母猪的24窝新生仔猪,则设置成另外3个饲粮铁处理组,即来源于以上正对照组母猪的哺乳仔猪饲喂未添加铁的玉米 豆粕 干乳清粉 鱼粉型基础饲粮开食料(负对照组),来源于以上有机铁组母猪的哺乳仔猪饲喂在负对照组基础上添加120mg/kg铁源于氨基酸铁络合物的饲粮开食料(有机铁组),和来源于以上无机铁组母猪的哺乳仔猪饲喂在负对照组基础上添加120mg/kg铁源于硫酸亚铁的饲粮开食料(无机铁组)。每窝仔猪中有一半于出生后的第1天内以葡萄糖酸铁形式一次性注射100mg铁,另一半则不注射铁。哺乳仔猪于出生后的第5天开始喂给开食料,直到27日龄断奶结束。结果表?An experiment was conducted using a total of 24 gestating sows (Landrace×Large White)and their piglets to investigate the effects of Fe source and Fe injection on Fe status of neonatal and nursing piglets.The experiment was divided into two phases,including a gestating phase and a lactating phase,and a completely randomized design was adopted.During the gestating phase,24 sows crossbred with Duroc,which had been pregnant for 70 days,were randomly allocated to one of three treatments,and fed a cornsoybean mealwheat bran basal diet supplemented with 80 mg/kg Fe as ferrous sulfate (positive control treatment,PC),the PC diet supplemented with 120 mg/kg Fe as Feamino acid complex (AvailaFe,US Zinpro Corp.,organic Fe treatment),and the PC diet supplemented with 120 mg/kg Fe as ferrous sulfate (inorganic Fe treatment),respectively.During the lactating phase,sows remained to be fed on the above treatment diets for gestating sows.However,neonatal piglets of 24 litters born from the above sows were allotted to one of another three treatments,including that piglets from the sows of the PC treatment were fed a cornsoybean mealdried whey mealfish meal basal diet with no supplemental Fe (negative control treatment,NC),piglets from the sows of organic Fe treatment were fed the NC diet supplemented with 120 mg/kg added Fe as Feamino acid complex(organic Fe treatment),and piglets from the sows of inorganic iron treatment were fed the NC diet supplemented with 120 mg/kg Fe as ferrous sulfate (inorganic Fe treatment).Onehalf of piglets from each litter were injected with 100 mg Fe as Fe dextran on day one after birth,and another half of piglets were not injected.Nursing piglets were fed on their respective creep feeds from day five through weaning on day 27.There were no differences (P>011) between organic Fe treatment and the positive control treatment in hemoglobin (Hb) concentration,hematocrit and plasma Fe of gestating sows on days 70,90,and 105,and milk Fe of lactating sows on days 10 and 21.Neon
