“…Responses were obtained where basal growth was suboptimal and were minimal when excellent growth occurred without supplementation. Numerous other workers including Warden and Schaible (1960), Heth and Bird (1962), Abbott and Couch (1970) and Franti et al (1973) have shown zinc bacitracin to be beneficial in studies with a variety of antibiotics and challenging organisms. Potter et al (1971) reported that the addition of 11 or 28 mg. of bacitracin from zinc bacitracin per kilogram of diet significantly improved body weight and feed efficiency in an eight-week study with young Medium White turkeys.…”

Broilers were grown to eight weeks of age at three experiment station locations to evaluate the influence of roxarsone and zinc bacitracin in the presence of aklomide. Dietary treatments consisted of a 4 x 4 factorial design in which levels of 0, 25, 50 or 75 p.p.m. of roxarsone were fed with 0, 15, 30 or 60 g./ton of zinc bacitracin. All treatment groups received 0.025% aklomide.Eight-week data indicated that zinc bacitracin alone produced no growth or feed efficiency response at any level of supplementation. Birds receiving roxarsone had significantly higher body weights at eight weeks of age than did birds receiving the control diet. The three levels of roxarsone produced statistically equivalent body weights.A level of 75 p.p.m. roxarsone in the presence of aklomide provided a significant improvement in feed efficiency over that seen for birds receiving either 50 p.p.m. of roxarsone or the unsupplemented control diet. Statistical evaluations indicated that the inclusion of roxarsone and zinc bacitracin in the presence of aklomide did not produce any body weight or feed efficiency interaction. The rate of mortality was not significantly influenced by any of the dietary treatments.

“…Anderson et al (1956) fed a high concentration (28 X 10 9 cells) of a mixed enterococci culture and observed a significant growth depression. However, Warden and Schaible (1960) obtained no response in chicks or poults from repeated crop inoculations of soy broth cultures (6.8 X 10 12 cells per ml.) Bogdonoff et al (1957) obtained added growth in broilers from semi-weekly crop inoculations of a mixed culture of E. colt and A. aerogenes in the presence of several antibiotics.…”
