Summary

Biotin supplementation improved turkey breeder hen performance, specifically egg production and hatchability, in one of two trials. Higher biotin levels showed benefits in later reproductive stages for hens.

Area of Science:

  • Animal Science
  • Poultry Nutrition

Background:

  • Biotin is essential for turkey breeder hen health and reproductive performance.
  • Dietary biotin levels can impact egg production and hatchability.

Purpose of the Study:

  • To evaluate the effect of different dietary biotin levels on turkey breeder hen performance.
  • To determine if higher biotin supplementation enhances reproductive efficiency.

Main Methods:

  • Two experiments were conducted using Nicholas strain female-line turkey hens.
  • Hens were fed corn-soybean meal-based diets with either low (.178 mg/kg) or high (.75 mg/kg) biotin levels.
  • Reproductive performance was monitored over a 27-week period.

Main Results:

  • In Experiment 1, hens fed high biotin showed significantly greater egg production (22%) and hatchability (10%) between 50-54 weeks of age.
  • In Experiment 2, biotin levels did not significantly affect reproductive performance between 33-57 weeks of age.
  • Results suggest higher biotin may benefit later reproductive performance in some conditions.

Conclusions:

  • Dietary biotin supplementation can positively influence turkey breeder hen reproductive performance.
  • The optimal biotin level may vary depending on the hen's age and production phase.
  • Further research is needed to fully understand biotin's role in late-stage turkey reproduction.
