The objective of the present study was to investigate the effect of dietary supplementation of attapulgite on the performance of fattening pigs from weaning to slaughter under field conditions in three commercial farrow to finish herds. In total 1890 pigs were used for six months: 720 pigs in Farms A and B, respectively and 450 pigs in Farm C. The pigs were equally allocated in three dietary treatments: CON, standard diet in each growing phase; ATT, standard diet that was supplemented with attapulgite at 7 kg/tn of feed; and ATT+, standard diet that was supplemented with 8 kg/tn of feed with a compound product based on attapulgite. Pigs that were fed diets that were supplemented with attapulgite (ATT and ATT+) had significantly higher (p < 0.05) average daily feed intake (ADFI) and a better feed conversion ratio (FCR), compared to the control (CON). In conclusion, attapulgite supplementation in the diet of pigs from weaning to slaughter can improve their performance in commercial farms.
本研究的目的是在三个商业性从产仔到育肥的猪群的田间条件下，调查日粮中添加凹凸棒石对断奶至出栏育肥猪生产性能的影响。总共1890头猪被用于为期6个月的试验：A农场和B农场各720头猪，C农场450头猪。这些猪被平均分配到三种日粮处理组：CON，每个生长阶段的标准日粮；ATT，在每吨饲料中添加7千克凹凸棒石的标准日粮；以及ATT+，在每吨饲料中添加8千克基于凹凸棒石的复合产品的标准日粮。与对照组（CON）相比，采食添加了凹凸棒石的日粮（ATT和ATT+）的猪平均日采食量（ADFI）显著更高（p<0.05），饲料转化率（FCR）更好。总之，在断奶至出栏的猪日粮中添加凹凸棒石可以提高其在商业农场中的生产性能。
