Ectoparasites in Poultry Farming: Diversity, Prevalence, and Environmental Determinants

Strategic Insights -

Recent research conducted in Togo's Maritime Region has shed light on the impact of ectoparasites on laying hens. The study, supported by the World Bank Group's Regional Centre of Excellence in Poultry Science (CERSA), aimed to explore the diversity of ectoparasites, evaluate their prevalence, and analyze environmental factors promoting their proliferation. The findings suggest a significant presence of ectoparasites, with an average infestation rate of 73.26% and a higher prevalence of acarid (59.54%) and louse (37.21%) parasitism.

Key Takeaways:

  • The study identified 10 species of ectoparasites affecting laying hens in Togo's Maritime Region.
  • The average infestation rate was 73.26%, with acarid and louse parasitism being more prevalent.
  • The research highlighted the importance of understanding environmental factors that promote the proliferation of ectoparasites.
  • The study emphasizes the need to focus on vector-borne diseases transmitted by ectoparasites to improve poultry farming practices.
  • 576 laying hens were examined in three prefectures, with 900 Isa Brown layer farms being the source of the birds.
  • Each farm consisted of an average of 500 laying hens, with 26-46-week-old birds being selected for the study.

Statistics:

  • Average infestation rate: 73.26%
  • Prevalence of acarid parasitism: 59.54%
  • Prevalence of louse parasitism: 37.21%
  • Number of laying hens examined: 576
  • Number of Isa Brown layer farms: 90
  • Average number of hens per farm: 500
  • Age of birds selected for the study: 26-46 weeks
