Prevalence of Losses and Barriers to Effective Control of Internal Parasites in Swine in St. Kitts (Tracey Challenger)

Printer-friendly versionSend by emailPDF version


This project was conceptualized based on information received from Public Health, that approximately 90% of pigs slaughtered at the Basseterre abattoir exhibited lesions consistent with internal parasites.  Pig producers were perceived to be resistant to recommendations to control parasites, due to a lack of hard evidence of losses associated with parasites.

 The objectives of this study were to:

- Determine prevalence of parasite-induced damage in pigs slaughtered at the Basseterre abattoir

- Describe current pig production practices with emphasis on management and parasite control

-  Describe producers´ current attitudes and beliefs regarding the control of internal parasites

 Two surveys were developed: Abattoir survey (source of the pigs, carcass weight, and the amount of parasite etc.) and On-farm survey (production, marketing, management practices, etc.).

 The results show that losses associated with parasite-induced damage in St Kitts are substantial. Indeed, although many producers are de-worming their pigs, the lack of sanitation combined with erratic treatment schedules means that internal parasites are not being effectively controlled.  Following this study, recommendations to improve owners’ education have been identified.
