Common pig diseases on commercial farms: a review

Abstract

Pig production on commercial farms is largely burdened by diseases in all production categories, especially in piglets. Health status of piglets is very delicate subject in large herds, in a confined space, considering diseases spreading. Variation of pathogens in pigs is of great importance not only in showing resistance to drugs, but the occurrence of genetic recombination, which affect the clinical signs and course of the disease. These complications make difficult to diagnose the disease and to apply appropriate therapy and prophylaxis. In pig commercial farms in Serbia most frequently encountered are the following diseases: neonatal colibacillosis, endemic disease, necrotic enteritis, circovirus infections, spirochetal colitis, enterohaemorrhagic syndrome, dysentery and respiratory disease complex. In recent years there was a high occurrence of respiratory disease complex (PRDC) which is increasing health problem in all production units. In this review paper, we present our experiences in diseases of different etiology determined on commercial pig farms.
