Benefits of Feed Supplementation of Yucca Schidigera

Benefits of Feed Supplementation of Yucca Schidigera

Yucca schidigera (YS) is a species of plants that grows in abundance in the southwestern United Staes and northern Mexico.  YS contains a variety of phytochemicals such as saponins, polyphenols, and resveratrol.  These phytochemicals have antimicrobial, antioxidant, and immunomodulatory properties.


Saponins have surfactant properties and when ingested can affect intestinal permeability, facilitate nutrient absorption, and benefit beneficial intestinal microbes.


Polyphenols act as antioxidants. This means they can neutralize harmful free radicals that might otherwise damage cells and increase the risk of cancer or other disease.


Resveratrol has antioxidant, anti-inflammatory, anti-viral, and anti-cancer properties. 

Supplementation of Yucca Schidigera to Livestock

Benefits have been found to include:

  • *Improved feed conversion and growth of chicks.
  • *Enhanced vaccine efficacy.
  • *Reduced antimicrobial treatments for BRD infected cattle.
  • *Positive effects on growth and feed efficiency, as well as health in nursery pigs, sheep, and laying quails.
  • *YS saponins inhibit rumen ciliate protozoa. Elimination of ciliate protozoa increases microbial protein supply by up to 30% reduces methane production up to 11%.
  • *Increased serum IgA and IgG concentrations in pre-weaned calves.
  • *Improved antioxidant capacity of pre-weaned calves.
  • *Decreased diarrhea in pre-weaned calves.
  • *Increased feed utilization in calves.

At MicroBasics we have harnessed the power of YS in many of our livestock formulas. Visit our on-line store to learn more!
