EFFICACY OF ALBENDAZOLE AGAINST SYNGAMUS- TRACHEA IN EXPERIMENTALLY INFECTED TURKEYS

Efficacy of albendazole of Syngamus trachea tested in groups of 8 to 9 turkeys experimentally infected with; 500 larvae each at the age of 8 days. From day 17 after infection, the animals were orally dosed with albendazole at 10, 5 or 2 mg/kg b.w. over 3 to 5 successive days. The efficacy was evaluated by daily inspection of symptoms, daily faecal egg counts and worm counts at post mortem on day 24 after infection. T he efficacy in the treated groups amounted to 100 %, 100 % and 94 %, r espectively. Remnants of wormpairs- mainly disintegrating males - were found in several animals of medicated groups as against all alive wor mpairs in the control turkeys. The study shows high efficacy of albend azole at reduced dose rate against patent gapeworm disease in turkey.
