Bioactive compounds in basal diet and sprouts
The profiles of bioactive compounds in the feed and sprouts are
shown in Table 3.
The amounts ofα-tocopherol in the feed, alfalfa and flax sprout groups
were 121.48, 47.07 and 42.01 μg g−1, respectively. Alpha-tocopherol
acetate, one the most commonly used antioxidants in animal feed, was
detected only in the standard diet, confirming the high resistance of
synthetic compounds to feed processing (Castellini, Dal Bosco,
Bernardini & Cyril, 1998).
Higher levels of antioxidants were found in the feed than in the
sprouts due to the different water content of the feed and sprouts
(12 vs 90%, respectively), with the only exception represented by
γ-tocopherol.
Levels of the carotenoids lutein and zeaxantin were much higher in
the alfalfa sprouts than in the control feed and flax sprouts (114.12 vs
21.37 and 13.36 μg g−1, respectively). Beta-carotene contentwas higher
in the alfalfa sprouts than in the control diet and not detected in flax
sprouts.
