- Patented feed enzyme = Endo-1,4-β-mannanase
- Produced by Paenibacillus lentus
- Heat
tolerance to pelleting temperatures of 190⁰ F/88⁰ C
- Approved for use in poultry (broilers and turkeys)
and swine diets in most major markets
- Hemicell HT** (dry) β-Mannanase (EC 3.2.1.78) (from Paenibacillus
lentus), not less than 72.5 MU/lb.
- Hemicell HT** (liquid) β-Mannanase (EC 3.2.1.78) (from
Paenibacillus lentus), not less than 590 MU/L.
How much substrate does Hemicell HT need to be effective?
Use of Hemicell HT to reduce unnecessary immune activity from β-mannans is expected to be cost effective in diets with at least 0.2% soluble β-mannans. The value of Hemicell HT increases in diets with increasing β-mannan content.1,2
What differentiates Hemicell HT from cocktail enzymes with β-mannanase on the label?
Hemicell HT is a patented enzyme product with a guaranteed minimum β-mannanase activity. This ensures sufficient β-mannanase activity in the final feed to prevent a feed induced immune response (FIIR) from β-mannans, when used as recommended. When evaluating a cocktail enzyme product, you should only consider enzyme activities with a minimum guaranteed potency.
