Abstract
90 Compound feed samples were screened for the presence of
aflatoxins.Feed samples were collected from the farm of Fac. Vet.
Med., Suez Canal Univ., during the period from May 1989 until,
January 1990. Out of the examined 90 samples, 74 samples (82.2%)
were found to contain aflatoxins. Aflatoxins B1 was detected in
74 samples (82.2%), B2 in 19 samples (21.1%), G1 in40 samples
(44.4%) and G2 in 9 samples (10.0%).
The minimum value of total aflatoxins in positive samples
was 3.2 ug / kg, the maximum value was 31.8 ug / kg and the mean
value was (12.14-1-1.24 ug/kg)
Out of 74 positive feed samples 15 sampls (20%) were found
to exceed the permisible limite (20 ug/kg).
A total of 90 tissue samples 30 each of liver, kidney and
muscle were obtained from slaughtered buffaloes. The aflatoxins
B1 and M1 could be detected in three liver samples (10%) with a
mean value of (0.0274-0.0 16 ug/kg), and (0.014-+-0.0018 ug/kg)
while, one sample (3.3%) of amimal meat showed to contain
aflatoxins B1 and M1 with a mean value of (0.0037±0.0037 ug/kg)
and (0.0037 +0.0037ug/kg), respectively.
The toxicological study showed that ducklings were stunted
in growth and the level of (S.G.O.T.), (S.G.P.T.) and alkaline
phosphatase were found to be higher than that of the control, and
then declined until a level similar to that of control or even
