研究了蒙脱石-氧化锌复合物（MMT-ZnO）对仔猪生产性能、腹泻、肠道通透性和形态学的影响。试验选用180头杜洛克×长白×约克郡（27 ± 1日龄断奶，平均体重7.2 ± 0.3 kg）仔猪，随机分为5组，每组6个猪圈，每个猪圈6头猪。试验组日粮为：（1）基础日粮+硫酸锌（ZnSO 4）100 mg/kg，（2）基础日粮+蒙脱石（MMT）2.0 g/kg。（3）基础日粮+500 mg/kg Zn（以ZnO形式）;（4）基础日粮+500 mg/kg Zn（以MMT-ZnO形式）;（5）基础日粮+2000 mg/kg Zn（以ZnO形式）。结果表明，添加500 mg/kg的MMT-ZnO锌或2000 mg/kg的ZnO锌可显著提高（P
Effects of montmorillonite-zinc oxide hybrid (MMT-ZnO) on performance, diarrhea, intestinal permeability and morphology were investigated. A total of 180 piglets (Duroc x Landrace x Yorkshire, average initial weight of 7.2 +/- 0.3 kg weaned at 27 +/- 1 d age) were randomly allotted to five groups for two weeks, each of which has six pens with six pigs per pen. The dietary treatments were: (1) basal control diet, 100 mg/kg of supplemental Zn as ZnSO4; (2) basal diet + 2.0 g/kg montmorillonite (MMT). equivalent to the MMT in the MMT-ZnO treatment; (3) basal diet + 500 mg/kg of Zn as ZnO; (4) basal diet + 500 mg/kg of Zn as MMT-ZnO; (5) basal diet + 2000 mg/kg of Zn as ZnO. The results showed that supplemental 500 mg/kg of Zn from MMT-ZnO or 2000 mg/kg of Zn from ZnO improved (P
