| description | Previous studies indicated high occurrence and level of aflatoxin M1 (AFM1) contamination
in raw milk due to the carry-over of aflatoxin B1 (AFB1) feed into AFM1 in milk of
Indonesian Friesian Holstein (IFH). Practical and effective method in feeding management of
contaminated feed is needed to minimize the adverse effects of aflatoxin on the animal and to
reduce its transfer into milk. This experiment was conducted to study the effects of natural
clays inclusion in naturally AFB1-contaminated diet for reducing aflatoxin transfer into the
milk of IFH cow. Eight mid-lactating IFH cows were used in a cross over research design.
Cows were randomly received naturally AFB1-contaminated diet (averaged 11.6 µg/kg)
added with 0.5% natural zeolite or 0.5% natural bentonite. After a period of 12 days, diets
were switched. Milk production was noted daily and milk samples were collected at lasted 3
days of each period for the determinations of AFM1 content and milk constituents. Data was
analysed by a paired t-test using SPSS version 16.0. Results showed no significant different
observed on milk production, milk fat content, and solid non-fat content of milk between
diets, those were 5.4 vs. 5.3 L/day, 3.37 vs. 3.43%, and 9.84 vs. 10.05%, respectively. ELISA
tests indicated that AFM1 content in milk of diet with natural zeolite was significantly lower
(p< 0.05) than AFM1 content of natural bentonite; those were 43 vs. 58 ng/L. However, the
carry over rate of AFB1 between diets were not significantly different (p> 0.05) (0.22 vs.
0.24%). This study concluded that natural zeolite inclusion could reduce AFM1content in
milk to the safe level (< 50 ng/L). |
