LSU Doctoral Dissertations

The objectives of this research were to determine 1) the effect of anise oil (AO) in pigs after exposure and re-exposure by dietary additions to sow and nursery diets; and 2) the maximum level of AO that could be fed to broilers and its effect on in-vitro growth of Clostridium perfringens (ClP); 3) to determine the effect of AO and diet type on growth performance of broilers after a challenge with ClP; and 4) to determine the effect of AO fed to broilers under commercial conditions. The results indicated that exposing lactating pigs to AO through the sow diet had …
