Abstract

Sarcoptes scabiei var suis was eradicated from a Belgian pig farm by using a combination of injections of ivermectin and ivermectin in the feed. The detection of mites in ear scrapings, and calculations of an average dermatitis score and a scratching index were used to evaluate the mange status of the pigs before and after the treatment. Before the treatment 28 per cent of ear scrapings of finishers were positive for the presence of mites, their average dermatitis score (ADS) was 0.92 and their scratching index was 2.0. There was a significant decrease in all three measurements during the year after the treatment, and one year after treatment, no mites were found in the ear scrapings; the ADS of the finishers was 0.31 and their scratching index was 0.16. Adult animals were negative for the presence of mites at all times, the ADS was below the cut-off level before and after treatment, and the scratching index decreased after treatment There was an economic improvement among the breeding sows and the fattening pigs. The feed consumption of the sows decreased by 5 per cent; rebreeding decreased by 4.55 per cent; average litter size increased by 0.33 live piglets born per litter and the farrowing index increased by 0.075 litters pe...Continue Reading
