Studies On The Compositive Prevention And Cure Of Contagious Atrophic Rhinitis Of Swine

Contagious Atrophic Rhinitis of pig is a chronic contagion, which character is nosepiece bone atrophy, chronic coryza, tear stains. NPAR is mainly aroused by Bordetella bronchiseptica(Bb) I ,but PAR by Pasteurella Multocida( type D ) and Bb. What does mainly harm to hoggery is the pollution or falling short of body grade, descend of growth speed and so on. By clinic diagnosis, X-rays diagnosis, pathology diagnosis, microbiology diagnosis, and some trials (including sensitiveness and filtration test of druggery, immunology test), we have designed three all-around schemes of prevention and cure, and tried some animals, then carried out one of them on a sweeping hogpen. The result shows that AR on this hogpen has been controlled effectively. The material and compositive schemes are that: 1. immunity: 1) boars , injected with routine import toxin bacterin. 2) young pigs, drop nose by SM2 and prevented by aureomycin; 2. crue by injection with kanamycin and insufflation of 2% boracic acid and potassium permanganate; 3. the control of condition: keep hogpen draughty, keep illumination moderate, and keep shed clean and dry; 4. strong breed administer: keep alimentation comprehensive and balanceable(especially Calcium and Phosphorus).
