Inwazje nicieni jelitowych u brojlerow i kur

A case of parasite invasion was described in farmstead flock caused by Ascaridia galii, Capillaria spp., Heterakis gallinae and Trichostrongylus tenuis. Levamisole given twice at the rate of 40 mg per 1 kg of body weight at two week intervals proved to be highly effective against round-worms with the exception of Capillaria spp. whose eggs were noted 10 per cent of the faeces for three weeks after the treatment. The therapy prevented the broilers from dying, improved their general condition, body gains after the treatment, however were not equalized with that noted in healthy groups. Nine farms with 1300 hens were tested for Ascaridia galii. Among the farm under study only one was free from A. galii invasion. In the other eight farms, the rate of invasion ranged from 3.5 to 31 per cent and the intensiveness of the infestation was from 1 to 38 round-worms in a sample. The studies showed that broilers in farm­stead flocks were Infested by A. galii, as were adult hens on farms.
