dc.description.abstract | Aflatoxin B1
(AFB1
) is a mycotoxin known to impair human and animal health. It is also
believed to have a deleterious effect on ruminal nutrient digestibility under in vitro batch culture
systems. The objective of this study was to evaluate the effects of increasing the dose of AFB1 on
ruminal dry matter and nutrient digestibility, fermentation profile, and N flows using a dual-flow
continuous culture system fed a diet formulated for lactating dairy cows. Eight fermenter vessels
were used in a replicated 4 × 4 Latin square design with 10 d periods (7 d adaptation and 3 d sample
collection). Treatments were randomly applied to fermenters on diet DM basis: (1) 0 µg of AFB1/kg
of DM (Control); (2) 50 µg of AFB1/kg of DM (AF50); (3) 100 µg of AFB1/kg of DM (AF100); and
(4) 150 µg of AFB1/kg of DM (AF150). Treatments did not affect nutrient digestibility, fermentation,
and N flows. Aflatoxin B1 concentration in ruminal fluid increased with dose but decreased to
undetectable levels after 4 h post-dosing. In conclusion, adding incremental doses of AFB1 did not
affect ruminal fermentation, digestibility of nutrients, and N flows in a dual-flow continuous culture
system fed diets formulated for lactating dairy cows. | |
