[Action of Bacitrafen Premix on layers and broilers].

Observations were made concerning the effect of Bacitraphen-Premix, consumed by poultry with their food. It was proved that similarly to other nutritive antibiotics, the preparation agreed well with them. It was also proved that it does not show toxicity--LD0 and LD50 were higher than the maximal does applied. Bacitraphen-Premix had a positive effect on the egg-laying abilities of layers, as well as on the fecundity ability and incubation qualities of eggs. It showed a definite antistress effect due to which it can be successfully used as a prophylactic means in poultry-raising in case of stress reactions.
