Examination of the Efficacy of Various Feed Additives on the Pathomorphological Changes in Broilers Treated with T-2 Toxin

A 21-day-long experiment was performed on 160 one-day-old “Ross" broiler chicks. This research was done with the aim of investigating pathomorphological changes in broilers exposed to a relativly small amount of T-2 toxin (2 ppm) and the possibility of prevention and/or alleviating adverse effects of T-2 toxin using various feed additives. Pathohistological examination showed negative consequences of T-2 toxin in all examined organs as degenerative changes developed in small intestine mucosa, enterocites and hepatocites necroses, as well as lymphocites depletion in bursa of Fabricius. Disparately from inorganic (Minazel-plus, Mz) and organic (Mycosorb, Ms) adsorbents, which did not provoke protective effects, in liver, small intestine and bursa of Fabricius of broilers who were given feed with T-2 toxin and mixed adsorbent (Mycofix-plus, Mf), mostly preserved structure of these organs could be noted.
