Summary

High mortality in turkey hens was linked to hepatic lipidosis. Vitamin E supplementation appeared to reduce losses, suggesting a potential nutritional intervention for this liver condition in poultry.

Area of Science:

  • Avian Pathology
  • Poultry Nutrition
  • Veterinary Medicine

Background:

  • Two flocks of 14,000 twenty-week-old turkey hens experienced increased mortality.
  • Clinical signs included dyspnea and cyanosis preceding death.
  • Hepatic lipidosis was identified as the cause of mortality.

Purpose of the Study:

  • To investigate the cause of increased mortality in turkey hens.
  • To evaluate the potential role of hepatic lipidosis.
  • To assess the efficacy of Vitamin E as a treatment.

Main Methods:

  • Necropsy examination of affected turkey hens.
  • Observation of clinical signs and mortality rates.
  • Administration of Vitamin E (25 IU per hen) in drinking water.

Main Results:

  • Necropsy revealed enlarged livers with pale areas, hemorrhages, lung congestion, and edema.
  • Mortality rates were 0.7% and 1.7% in the two flocks over 12 days.
  • Vitamin E administration appeared to reduce mortality.

Conclusions:

  • Hepatic lipidosis contributed to significant mortality in these turkey flocks.
  • Vitamin E supplementation shows promise in mitigating mortality associated with hepatic lipidosis in turkeys.
  • Further investigation into nutritional and environmental factors is warranted.
