The United States Department of Agriculture reported that sow mortality ranges from 2.5% to 3.7% each year, depending on herd size1. It also was stated that annual mortality rates of sows in typical confined-sow herds should not exceed 3%2. In contrast, some sow herds experience annual losses of at least 10% of inventoried females3-6. The reasons for sow mortality are poorly understood; however, l ...

Over the last 30 years, diseases caused by emerging swine viruses (ESV) have acquired great relevance, more than in other species. Diseases caused by porcine reproductive and respiratory syndrome virus (PRRSv), high pathogenicity porcine epidemic diarrhea virus (PEDv), porcine circovirus type 2 (PCV-2), and influenza virus H1N1pdm09 had great economic impact. Others, however, such as porcine enter ...

Introduction: Enteric infections cause economic losses in pig production. Increases in costs are associated with reduced average daily gain (ADG), increased mortality rate and increased in use of antibiotics. Porcine proliferative enteropathies (PPE), swine dysentery (SD), porcine spirochetosis and salmonellosis are enteric diseases caused by L. intracellularis (LI), B. hyodysenteriae (BH), B. pil ...
