Abstract

The objective of this experiment was to study the effect of three antibiotics, in two levels as an antistress factor on vacination against Newcastle disease and Fowlpox. Seven treatments were compared: T1 = ration without antibiotic; T2 ration supplemented with 100 g of chlortetracycline per metric ton; T3 = ration supplemented with 200 g of chlortetracycline per metric ton.; T4 = ration supplemented with 100 9 oxitetracyciine per metric ton.; T5 = ration supplemented with 200 g oxitetracycline per metric ton.; T6 = ration supplemented with 100 g erithromicin per metric ton.; T7 = ration supplemented with 200 g erithromicin per metric ton. Statistical analysis did not show differences (P < 0,05) as to live weight, feed conversion and rate of mortality that could be attributed to the treatments, in the period to 0 to 35 days and 0 to 63 days, during winter and summer.
