【Abstract】 24 L·Y piglets weaned at 35d of age, allotted equally into experiment group andcontrol group on the basis of litters, initial weight and sex, each with 3 replicates of 4piglets were fed the experment ration （containing 2000mg/kg of zinc from ZnSO₄） andthe control ration （containing 126mg/kg of zinc from ZnSO₄） respectively. The resultsshowed that 2000mg/kg of zinc reduce diarrhoea rate of weaning piglets by 70. 56% （P<0.05）, and has no influence on average daily gain （ADG） and feed/gain ratio （F/G）compared with control treatment during 30 days postweaning.更多还原
