Area of Science:

  • Veterinary Medicine
  • Animal Nutrition
  • Dermatology

Background:

  • Zinc deficiency is a significant concern in livestock, impacting animal health and productivity.
  • Clinical signs of zinc deficiency in sheep can be varied and severe, affecting young animals disproportionately.

Purpose of the Study:

  • To diagnose and describe a case of zinc deficiency in sheep in Khartoum Province.
  • To investigate the clinical and histopathological manifestations of zinc deficiency in affected lambs.
  • To evaluate the efficacy of zinc supplementation for treating zinc deficiency in sheep.

Main Methods:

  • Clinical examination of affected sheep, noting symptoms like skin lesions, depression, and gait abnormalities.
  • Histopathological examination of skin biopsies to identify characteristic changes such as hyperkeratosis and parakeratosis.
  • Treatment of affected animals with oral administration of zinc oxide and observation of response.

Main Results:

  • Diagnosis of zinc deficiency in a sheep flock in Khartoum Province, with young sheep and lambs being most affected.
  • Observed clinical signs included skin lesions, depression, wool eating, flexed knees, and stiff gait.
  • Histopathology confirmed hyperkeratosis and parakeratosis in skin samples.
  • Rapid clinical improvement was noted following oral zinc oxide supplementation.

Conclusions:

  • Zinc deficiency can manifest with significant dermatological and locomotive signs in sheep.
  • Histopathology aids in diagnosing zinc deficiency by revealing characteristic skin changes.
  • Oral zinc oxide is an effective treatment for zinc deficiency in sheep, leading to rapid recovery.
