Severe pododermatitis in turkeys is linked to diet and litter conditions. Biotin levels and wet litter are key factors, with higher incidence in males, requiring further management research.

Area of Science:

  • Avian Health
  • Poultry Science
  • Veterinary Pathology

Background:

  • Pododermatitis, or footpad lesions, is a significant welfare concern in commercial turkeys, distinct from its prevalence in broiler chickens.
  • Documented causes include dietary imbalances (e.g., soybean meal, biotin, methionine) and environmental factors like wet litter conditions.
  • Monitoring of footpad lesions is standard practice in the US and UK, with notable differences in scoring and incidence between countries and sexes.

Purpose of the Study:

  • To investigate the multifactorial etiology of severe pododermatitis in turkeys.
  • To analyze the influence of dietary components, litter quality, and management practices on footpad lesion development.
  • To compare pododermatitis incidence and severity between the United States and the United Kingdom.

Main Methods:

  • Review of existing literature and data on turkey pododermatitis.
  • Analysis of factors including diet composition, litter type (straw, wood shavings), breed (British United Turkey, hybrids), and production systems.
  • Comparison of lesion scores and incidence rates between the US and UK, considering sex (toms vs. hens) and performance parameters.

Main Results:

  • Pododermatitis incidence is higher in male turkeys (toms) than females (hens) in both countries.
  • Dietary factors (biotin) and litter conditions (wet litter) are strongly associated with footpad lesions.
  • No significant association was found with other lesions, specific breeds, or general performance metrics like weight gain or age.
  • Higher protein diets in the UK contribute to poorer litter conditions compared to the US.

Conclusions:

  • Pododermatitis in turkeys is primarily influenced by nutritional status (especially biotin) and litter moisture.
  • Management practices, including litter management and potentially stocking density, play a crucial role in mitigating footpad lesions.
  • Further research is essential to elucidate specific management strategies that reduce the incidence of pododermatitis in turkey flocks.
