[Attempt at restoring the health of pigs suffering from atrophic rhinitis]. / Pokus o ozdravení chovu prasat s výskytem sípavky.

A group of 24 sows selected from herds affected by atrophic rhinitis was subjected to the study of the therapeutic effect of the administration of wide-spectrum antibiotics combined with an improvement of the zoohygienic conditions and with full-value nutrition in the pre-partal period and during lactation. It was found that the mentioned measures in sows before parturition and their housing in a sanitized farrowing house during treatment generally improved the health of the sows and enabled the rearing of healthy piglets. The mortality rate during rearing up to the age of 28 days was 12.5%. In the control group of piglets and sows the losses amounted to 29%; the clinical symptoms of rhinitis were found in 11% of the piglets already at the age of 28 days.
