Swine diseases, symptoms and prevention

Swine diseases, symptoms and prevention

Swine production faces significant challenges from a variety of gastrointestinal and metabolic disorders that threaten herd health and economic viability. Among the most prevalent issues are parasitic infections like coccidiosis, which compromises the intestinal health of young piglets, and post weaning diarrhea, a condition triggered by the immense physiological and environmental stressors of the weaning transition. Furthermore, the industry must contend with severe infectious diseases such as dysentery, characterized by debilitating mucohemorrhagic diarrhea. Understanding the etiology and symptoms of these conditions is crucial for implementing effective prevention strategies and ensuring sustainable production.

Coccidiosis

⇒ Coccidiosis

a prevalent parasitic disease, often flies under the radar in its early stages, yet its impact on piglet health and overall farm economics can be profound. Primarily caused by Cystoisospora suis (formerly Isospora suis), this protozoal infection targets the delicate intestinal lining of young piglets, leading to malabsorption, stunted growth, and increased susceptibility to secondary infections.

Post weaning diarrhea

⇒ Post weaning diarrhea

The period immediately following weaning is arguably one of the most stressful and vulnerable times in a piglet’s life. The abrupt separation from the sow, the drastic change in diet from highly digestible milk to solid feed, and the shift in environment and social structure all converge to create a perfect storm for physiological and immunological disruption.

Dysentery

⇒ Dysentery

stands as a formidable challenge in pig production worldwide, a severe infectious disease primarily characterized by mucohemorrhagic diarrhea. Caused predominantly by the bacterium Brachyspira hyodysenteriae, and increasingly by other strongly beta-hemolytic Brachyspira species like B. hampsonii and B. suanatina, this condition continues to inflict significant economic losses on swine operations.
