Efficacy of different adsorbents in alleviating zearalenone effects on performance of pigs

The investigation of the influence of zearalenone effects on performance of pigs and the possibility of the application of modified clinoptilolite (MC) and esterified glucomanane (EGM) in alleviating and/or prevention of harmful effects was performed by the experiment of pigs nutrition. The experiment lasted for 31 days, and the group of pigs was fed with uncontaminated feed while experimental groups were fed with feed containing 3.84 ppm of zearalenone. In pig feed of the second and third experimental group MC and EGM in the amount of 0,2 and 0,1% were added. The pigs of the control group accomplished daily growth of 0.569 kg with feed con- version of 1.793 kg. The presence of F-2 toxin in feed affected adversely production results. The addition of MC or EGM to contaminated feed improved production results, but not to the level of the control group. The obtained results point at the fact that adsorbents can only partially prevent harmful effects of F-2 toxin
