Sarcoptic mange infestation in pigs: an overview

Area of Science:

• Veterinary Parasitology
• Animal Husbandry
• Agricultural Economics

Background:

• Sarcoptic mange, caused by Sarcoptes scabiei var. suis, is the most prevalent mange infestation in pigs globally.
• External parasitic infestations like sarcoptic mange are often overlooked by pig owners compared to internal parasites, despite significant economic implications.

Purpose of the Study:

• To review existing research on Sarcoptes scabiei var. suis infestation in pigs.
• To provide a comprehensive overview of the parasite's prevalence, life cycle, pathology, clinical signs, diagnosis, treatment, and control strategies.
• To highlight the comparative scarcity of research on this infestation in India.

Main Methods:

• Literature review of past and present research on Sarcoptes scabiei var. suis in pigs.
• Compilation of data on prevalence, life cycle, clinical manifestations, and economic impact.
• Analysis of research output in India versus other countries.

Main Results:

• Sarcoptic mange infestation in pigs leads to significant economic losses through morbidity, mortality, reduced fertility, and impaired feed conversion.
• Research on Sarcoptes scabiei var. suis in India is notably less extensive than in other regions, potentially due to underreporting or neglect.
• Key aspects covered include pathological lesions, hematobiochemical alterations, and diagnostic approaches.

Conclusions:

• Sarcoptic mange poses a considerable economic threat to the swine industry worldwide.
• The limited research on pig mange in India underscores a need for further investigation and data collection.
• Raising farmer awareness through extension programs is crucial for effective management and prevention of economic losses associated with Sarcoptes scabiei var. suis.
