Document Type and Number:
WIPO Patent Application WO/2007/003068
Kind Code:
A1
Abstract:
The present invention provides a feed additive, its preparation method and application.
The feed additive is oligomeric proanthocyanidins, the oligomeric proanthocyanidins
are bi-, ter-or tetra-polymers. The preparation method of the feed additive
is: using condensed tannin or extract having condensed tannin as material and
20-60% hydrogen peroxide or potassium chlorate as oxidizer, carrying out oxidizing
reaction 15-120 minutes under the condition of pH6-7 and temperature 30-50°C
to yield a subtransparent liquid with a color of yellow to brown which has then
separated and purified to obtain the feed additive. The feed additive can be used
in feed for preventing and treating animal coccidiosis and its concentration
in the feed is 5-600 ppm. The feed additive can be used in feed for chicken, duck,
quail, pigeon, rabbit and pig. It also can be used together with other anticoccidiosis
drugs, antioxidant, or enzyme preparation.
