  • Title: Effects on laying hens of feeding corn invaded by two species of Fusarium and pure T-2 mycotoxin.
    Author: Speers GM, Mirocha CJ, Christensen CM, Behrens JC.
    Journal: Poult Sci; 1977 Jan; 56(1):98-102. PubMed ID: 605028.
    Abstract:
    Balanced rations containing 2.5 and 5.0% of corn invaded by Fusarium tricinctum, (with 8 and 16 p.p.m. of T-2 toxin) were fed to White Leghorm laying hens. The ration containing 5% of the fungus-invaded corn resulted in reduced feed intake and reduction in weight gain and in egg production. Rations containing 2.5 and 5.0% of corn invaded by F. roseum 'Gibbosum' (with 25 and 50 p.p.m., respectively, of monoacetoxyscirpenol) resulted in an abrupt decrease in feed intake to 10-20% of normal, subsequent loss in weight, and cessation of egg production. Purified T-2 toxin consumed at the rate of 16 p.p.m. in the ration resulted in loss of body weight and decreased egg production; lesser amounts of T-2 toxin resulted in lessened but still detectable injurious effects. Mouth lesions developed in the birds fed these rations, their severity being proportional to the amount of toxin present.
