title: [Incidence and intensity of atrophic rhinitis in pigs in relation to age and zoohygienic conditions].
abstract: The occurrence rate of the clinical forms of atrophic rhinitis in pigs kept in cotes was lower by up to 10% than in pigs kept in brick-walled farrowing house under bad zoo-hygienic conditions. In both types of housing the lowest occurrence rate of rhinitis was reported in the summer months. In the cotes rhinitis affected 10% of the piglets in summer and 16% in autumn. In the farrowing house rhinitis was observed in 12% of the piglets in summer and in 25% in autumn. The first symptoms of disease occurred in the piglets at the age of two weeks and the occurrence rate of the clinical forms of rhinitis was found to increase with age.
