Popis: THE effect of therapeutic and prophylactic levels of sulfaquinoxaline on the growth and feed efficiency of chicks has been reported for many growth trials in which the chicks were either inoculated with sporulated oocysts or exposed to natural coccidial infections. In only a relatively few growth studies have coccidia-free chicks been used, even though the use of such chicks would have permitted much more critical studies of the effect of the drug on growth and feed efficiency. Using coccidia-free chicks Singsen et al. (1948) obtained larger but nonsignificant gains when a high-energy diet containing 0.01 percent sulfaquinoxaline was fed continuously for seven weeks. Similar results were reported by Koutz (1948). Larger amounts of sulfaquinoxaline have produced inconsistent results. Singsen et al. (1948) obtained a “definite reduction” in the growth of coccidia-free chicks fed a diet containing 0.03 percent sulfaquinoxaline. Their male chicks were apparently unaffected by this level of the …
