Realized test, with piglets, to evaluate Gustor B Coated and encapsulated calcium butyrate demonstrate Gustor B Coated efficacy

An experiment was set up to evaluate the effect of two sources of protected butyric acid: GUSTOR B (Sodium Butyrate encapsulated with vegetable fat) and Calcium Butyrate encapsulated with vegetable fat (CBE) on performance, histology and Butyric acid content in Gastro Intestinal Tract of piglets. A total of 352 animals divided in two groups with 8 replicates per group, were given either a standard diet with GUSTOR B Coated or the same feed containing Calcium Butyrate encapsulated with vegetable fat (dosage at same cost per ton of feed). The trial period was 26 days after weaning. The GUSTOR B Coated fed animals showed a higher body weight (+1.5%), average feed intake (+2.9%) and average daily gain (3.5%) than those fed Calcium Butyrate encapsulated. Gustor B Coated improved feed conversion ratio by 0.8%. Also, the  Gustor B Coated fed animals had a higher concentration of butyric acid in the duodenum (+31%) and Colon (+24%) and showed a higher villi height (+24%), crypt depths (+20%) and mucosa thickness (+22%) than those fed CBE. It can be concluded from this trial that the addition of sodium butyrate encapsulated with vegetable fat (Gustor B Coated), allows more butyric acid to get to the distal sections on the GIT than calcium Butyrate encapsulated. It also shows a greater trophic effect on duodenum epithelial cells than CBE. Thus, the Gustor Coated feeds produce better absorption and this explains the improved results in growth and production parameters
