Comparison of six different regimens for the control of atrophic rhinitis in swine.

Effectiveness of six different programs of atrophic rhinitis (AR) control was evaluated under field conditions. Efficacy of treatments was recognized on the basis of--comparative evaluation of the average daily gain (ADG), morphometric examination of turbinate bones and computer conchal morphometry (TPR). Usefulness of the evaluated regimes differed significantly. TPR appeared to be the most objective method for AR evaluation. Correlation between severity of turbinate atrophy and ADG was only partial.
