Tractor collecting silageSilage inoculants to maximize nutrient and dry matter protection

We know that silage-making is at the core of what you do. However, not all of the silage produced will make it to the feed passage. From fresh crop to harvest and through storage, the feed value drops, as does the physical quantity of the silage — by as much as 25%! This can hurt animal performance and increase your feed costs.

Egalis® is a new range of high-quality silage inoculants from Alltech® that maximizes nutrient quality retention and reduces dry matter loss. This means you have more silage to feed, better silage to feed and fewer concerns about wasting feed. Through enhanced palatability and increased dry matter intake, Egalis contributes to more profitable milk and meat production.

The Egalis range of silage inoculants

Egalis drives quick and proper fermentation, which helps epiphytic bacteria control fermentation through the use of other specific bacteria.

The Egalis product line is available in several variations and packaging options for farms of all sizes to provide you the flexibility and ease of application needed for a stress-free silage season.

Supported by 40 years of fermentation research and expertise

Fermentation is at the core of what we do at Alltech, and silage-making happens to be the largest industrial fermentation process around the world. The Egalis range of products brings together our more than four decades of expertise in fermentation, utilizing strains of bacteria that were specifically selected by our scientists to maximize nutrient and dry matter protection and improve animal performance.

Together with our on-farm support team and through our range of analytical services, we help improve fermentation to produce quality silage, enabling you to hold on to more of what you grow, from field to feed passage.

The basics of fermentation

Fermentation is loosely defined as the breakdown of a substance by bacteria, yeast or other microorganisms. In silage, a natural fermentation process, which takes place in the absence of oxygen, breaks down the plant sugars in the forage crop and converts them into acids. These acids drop the pH of the silage and help prevent the development of molds and fungi.

Keys to fermentation:

  1. A reduced amount of oxygen present
  2. Adequate sugar levels and carbohydrates to promote bacterial activity
  3. Appropriate composition and temperature and suitable numbers of microbial bacteria
  4. Proper harvest moisture

The role of Egalis

Suitable for use on all forages, Egalis efficiently and rapidly drives fermentation to a stable, final pH. It is comprised of specific strains of Lactobacillus plantarum and Pediococcus pentosaceus, which work in conjunction to rapidly lower the pH to a more even and suitable number. This more controlled fermentation offers more consistent and better-quality silage for your animals, which helps you maintain optimal animal performance.

Benefits of Egalis:

  • Maximizes forage quality
  • Aids in nutrient retention
  • Reduces dry matter losses
  • Drives sustainable feed usage

Silage: Preserve your dollars

There’s a tremendous amount of money invested in silage, from growing the crop to storing it. Yet shrink on dairies ranges from 15 to 25 percent, if not more! This level of shrink can equate to a loss of 15 to 25 cents for every dollar invested in putting the silage up.
