Summary

Supplementing pig diets with biotin significantly reduced claw lesions in sows after their first litter. This dietary addition improved hoof integrity, crucial for breeding sow health and productivity.

Area of Science:

  • Animal Science
  • Nutritional Biochemistry
  • Veterinary Medicine

Background:

  • Hoof integrity is vital for sow productivity and welfare.
  • Nutritional deficiencies, including biotin, can impact hoof health.
  • Early-stage dietary interventions may prevent hoof lesions.

Purpose of the Study:

  • To evaluate the effect of biotin supplementation on hoof lesions in breeding sows.
  • To determine if early biotin supplementation impacts claw integrity throughout lactation.

Main Methods:

  • Eighty female pigs were fed either a control or biotin-supplemented diet from 25 kg liveweight.
  • Claw lesions were recorded at 170 days of age and after each of the first four litters were weaned.
  • Statistical analysis compared lesion incidence between control and supplemented groups.

Main Results:

  • No significant difference in lesions was observed at 170 days of age.
  • Biotin-supplemented sows showed significantly fewer claw lesions post-first weaning (P < 0.05).
  • Cracks at the heel/toe junction and white-line region were predominant injuries.

Conclusions:

  • Early and continuous biotin supplementation improves hoof horn integrity in breeding sows.
  • Dietary biotin is essential for maintaining claw health during the demanding lactation period.
  • Supplementation contributes to sow welfare without affecting culling rates.
