results revealed that ANT and AV1 treatments caused a significantly (P<0.05)
increase in feed intake at 21 and 35 days of age and feed conversion ratio at
21 days of age. The highest weight gain was obtained by AV1 at 35 days of age
(P<0.05). Feeding diet AV1 and AV3 significantly (P<0.05) improved the serum
antibody titers against IDBV (Infectious bursal disease and Newcastle disease
