Abstract:

by some strains of Aspergillus flavus and Aspergillus parasiticus during growth, on feeds and foods.
The fungal spores are found worldwide, in air and soil, and infest both living and dead plants and carryover aflantoxin B
animals. An experiment was conducted to investigate the concentration, total excretion and
(AFB) into milk as Aflatoxin M?Nine crossbred lactating goats were
divided into three groups of three each, based on the level of milk production. Commercial
Afiatoxin
(AFB,) was administered to all groups at a rate of 100 ppb in the diet. Group I served
as control (TJ. In group II (T,), calcium bentonite (CaB) and in group III (TJ, activated charcoal
(AC), were added at the rate of 1 % of Dry Matter Intake (DMI). Dry matter intake was not
significantly different (P>0.05) among TI (1.22), T2 (1.14) and T3 (1.13). Daily milk yield was also
not significantly different (P>0.05) among treatments
(0.91), T2 (0.86) and T3 (1.03) during the
experimental period of 14 days. The AFM? concentration, excretion and carry-over of AFB? in Ti
continued to increase with lime, whereas, the same was seen to decline in the adsorbent fed
groups T, and T3. The results suggest that supplementation of CaB or AC at 1% of DMI for
lactating goats result in a reduction in AFM? content in milk and carryover of aflatoxin from feed
to milk without causing any change in composition of milk.
