| 摘 要： | 调查结果显示，由于集约化生产和采用封闭式饲养方式以及日粮结构的变化，改变了大围子猪的传统生态环境，导致矿物质营养不足而对猪的健康、生长速度和繁殖机能产生不良影响．试验结果表明，在母猪日粮中加入矿物质元素添加剂，微量元素缺乏症会很快消失，母猪的雌性胎儿出生率也比对照组提高２５．０％～２８．６％．

| Abstract: | The intensive producing,the changes of dietary constituent and the confiningfarming have changed the traditional ecological environment of local sow;which leads to thedeficiency of mineral and bring harmful to sowys health,growth rate and reproductivity.Ifmineral additives have been added to the sow diet ,the symptos of lacking microelements willsoon disappear,and the number of piglet will increase,the female embryo birth rate will rise25.4%to 28.6% compared with the control group. |
