Development of Microencapsulation technology for targeted delivery of enzymes in the gastrointestinal tract of ruminants

Forages consist of 40 to 100% of ruminant diet. Forages are often high fibre and low quality, and digestive pathways can further limit digestibility and nutrient utilisation. The use of targeted enzymes can potentially improve fibre digestibility and feed utilization rate. The challenge is the delivery of such enzymes in active form to the hind gut for digesting the residual fibre fraction, since passage through the upper gastrointestinal tract of ruminants and specially the low pH environment of the abomasum can cause inactivation of target enzymes.
