Featured Technology
Mannanase Treatment of Copra Meal
Mannanase is an enzyme used to convert copra meal into a more effective feed ingredient through solid state fermentation. It is produced using a bacterial soil isolate, Streptomyces sp. no. 17. The enzyme was found to hydrolize the copra meal fiber composed mostly of galactomannans which have low digestibility and often have a laxative effect in poultry and swine.
Mannanase treatment results in a copra meal with low fiber content, high energy value, increased digestibility, and improved nutritional quality by making proteins, carbohydrates, and lipids more available or metabolizable for the animals, thus, improving its feeding value.
