| Popis: | GARD and Means (1958) studied the effects of penicillin and tylosin on chick growth and layer performance. These workers used 50 White Rock cockerels and 50 White Rock pullets per treatment and reported that penicillin improved growth and feed efficiency when compared to the control. Tylosin, at a level of 4 grams per ton of feed, improved growth and feed efficiency over that produced by penicillin. When added to the ration of laying birds, at a level of 20 grams per ton, tylosin improved egg production and feed efficiency slightly. Barnes et al. (1958) found the antibiotic to be highly effective in the treatment of experimentally induced Mycoplasma gallisepticum (PPLO) infection when injected intramuscularly or intraperitoneally at 5 mgs./lb. body weight or when added to water at a level of 3 gms./gal. These same workers found in later studies (1960) that tylosin effectively controlled experimental Mycoplasma gallisepticum infections of young … |
