Sulfaquinoxaline Chick Intoxication Experiment

The aim of the experiment was to correctly evaluate the effect of different concentrations of sulfaquinoxaline on the growth development and various organs of chicks,especially the immune organs.The paper analyzed the intoxication function.Two concentrations of sulfaquinoxaline at 0.2 % and 0.5 % were given to Hyline brown-egg chicks at the age of 7 days for duration of 14 days.The experiment has established the model of sulfaquinoxaline chick intoxication experiment.The chicks under the experiment have been vaccinated with Newcastle disease according to normal immune procedure.After observation of the clinic symptoms,chicks were killed on day 7 and day 14,then weighed,measured the index of the immune organs and the antibody level of Newcastle disease.The experiment has observed the pathologic lesions and histopathological changes and evaluated the effect of sulfaquinoxaline on chicks.This study has provided scientific background for the correct use of sulfaquinoxaline and promoting the development of poultry industry.
