Abstract
Experimental mycotoxicoses were induced singly and in combination in 48 newly
hatched turkey poults (Meleagridisgallopavo - Beltsville small white) for a period of 0 to 13
weeks by feeding diets containing 100 ppb AF and 1 ppm T-2 toxin. The AF was produced
on rice while T-2 toxin was produced on corn grits using Aspergillus parasiticus NRRL 2999
and Fusarium sporotrichioides respectively. The AF and T-2 toxin from cultures were
quantified by TLC. Weighed amounts of powdered culture material was incorporated into the
toxin free diet and were adjusted to 100 ppb AF and 1 ppm T-2 toxin. A detailed post mortem
was conducted on sacrificed bird during the 7th week and 13th week of experimental period.
Weights of liver, spleen and bursa of Fabricius and gross lesions were recorded. Only relative
spleen weights significantly (P<0.05) decreased in the toxin treated groups except T-2 when
compared to the control. The AF fed birds during the 7th and 13th week revealed enlarged and
congested, pale or patchy yellowish discoloured liver and translucent gall bladder distended
with thin, light green bile. The kidneys were mildly congested.
