Autolyzed Yeast icon pigicon cow

Natural and Efficient Immune Enhancer

Autolyzed Yeast is a natural component derived from yeast Saccharomyces cerevisiae. The main ingredients in Autolyzed Yeast are β-glucan and mannan, which can increase immunity and block pathogens.

Flo-Aidicon pig icon chickenicon cow

A Hydrated Sodium Calcium Aluminosilicate. An anti-caking agent which absorbs moisture, that can form chunks in the feed and contribute to mold growth, which will contaminate clean feed. In instances of large amounts of sticky ingredient in feeds, Flo-Aid will improve feed flow-ability through feeding systems.

GroPro icon pigicon cow

Functional Nucleic Acid and Protein for Young Animals

A feed ingredient derived from yeast which enhances all the nutritional and health benefits of the yeast. It provides young animals digestible proteins and functional nucleotides to help them get through critical early growth stages.

For the physical characteristics of less feed intake, imperfect digestive function, poor immunity and weak stress resistance in young animals, which requires us to choose better feedstuff in designing the ideal formulation for them. GroPro as a functional feedstuff from yeast is used extensively in young animals' diet formulation in China. GroPro not only provides an excellent protein source, but also provides young animals functional ingredients such as nucleic acid and small peptide for growth. GroPro has been accepted by many feed millers as a protein source.

Lube Aid icon cow

A die lubricant, which reduces friction in the die due to ingredients such as high mineral, high milk diets, or high distillers. Reducing the friction allows for greater throughput, less wear on the die and rolls, which reduces costs, and lowers electrical consumption. Lower friction on feed passing through the die reduces scorching on the pellets being made and improves the taste of feed.

Maxi-Bond icon pigicon chickenicon cow

A low inclusion pellet binder and die lubricant, its unique ingredients create hard durable pellets by binding the protein and starch ingredients together to form an outer protective coating. Maxi-Bond increases throughput, reduces die friction, improves hardness, increases durability and lowers production costs. It is a free flowing white powder which mixes well with other ingredients.

Mold-X icon pigicon chickenicon cow

A mold inhibitor comprised of several synergistic acids which stops mold growth, compatible with all ingredients and vitamin premixes.

  • Low level incorporation
  • Small particle size maximizes dispersion
  • Increased surface area for contact increases effectiveness

Lowers pH of feed, controls non-beneficial yeast, giving slow release for longer control. Buffered to reduce caustic effect on equipment, and reduce discomfort to all who handle it.

Pro 88 Cheese Powder icon pig

A blend of several cheeses and soy flour for flow-ability. High in protein and fat, which is readily available to the young pig. Very aromatic, and dried at low temperature which does not alter the milk nutrients, 4000 kcal/ kg, available in 25kg bags.

Selenium Yeast icon piggyicon cow

Organic Selenium from Biofermentation

Selenium Yeast is a kind of organic selenium which is produced by submerged fermenting Saccharomyces cerevisiae in selenium-rich media. The selenium is in organic form which is suitable for absorption and utilization, and reducing oxidative damage.
