Optimizing Progeny Development Through Maternal Supplementation

What is MINTREX®?

For poultry producers seeking vast improvements in breeder hen performance, MINTREX® chelated trace minerals optimize key production parameters above levels obtained by other chelated mineral sources. Only MINTREX® can reduce mortality up to 12%, decrease under-grade eggs up to 13%, and increase egg production and hatchability up to 8%.

MINTREX® Zn is a highly bioavailable source of zinc, combining methionine hydroxy analogue with the essential trace mineral in a 2:1 chelated molecule. Zinc plays a critical role in embryo and post-natal development.

Why is Maternal Nutrition Important?

Maternal nutrition has an influence on embryonic development through the deposition of nutrients the egg, which is controlled by nutrient delivery from the breeder hen’s blood. If the developing embryo does not receive the nutrients required for development, then the growth and development of the fetus, as well as the performance of the new offspring, could be compromised.

In newly hatched chicks, the immune system is functionally immature, and the young chicks are dependent on maternal antibodies transferred through the egg yolk. The intestine is also not mature until the second week of life, creating increased vulnerability to pathogens, causing gut lesions in young birds. However, early nutrition intervention has been shown to be effective for enhancing innate immunity and intestinal development, which is involved in epigenetic reprogramming.

How Does MINTREX Help?

  • MINTREX Zn supplementation in breeder hens can enhance egg yolk zinc concentration, as compared to zinc sulfate, which aids in greater zinc delivery to progeny chicks.
  • The addition of MINTREX Zn in breeders has also been shown to be more effective than zinc sulfate in boosting progeny immunity and gut barrier function.
  • MINTREX® Zn supplementation in breeder hens has been shown to be more effective than zinc sulfate in reducing gut inflammation in progeny chicks by epigenetic regulation of an antiinflammatory protein (A20).
  • Through regulation of specific protein synthesis and degradation pathways, zinc supplementation can support increased breast muscle yield in progeny birds.

    Giving Chicks the Proper Start
    A poultry breeder measures success on the ability to supply a consistent set of high quality chicks.The diet of the hen plays an important role to ensure adequate nutrient transfer to the egg yolk and developing embryo. Through maternal zinc supplementation, changes can be made on a cellular level to effectively reprogram the genetic tendencies of the progeny chick.
