GUSTOR N’RGY & Nutrients Concentration on Broilers Gut Health

The study, presented in IPSF 2016, compared the effect of sodium butyrate protected with PFAD sodium salt (GUSTOR N’RGY) with different diets on gut health. A 2 x 2 factorial design was used with two basal diets based on wheat, barley and soy: S (standard nutrient diet) and L (low nutrient diet: – 60 Kcal/Kg of ME and -2.3% AA) with or without GUSTOR N’RGY at 1 kg/t. A total of 200 Cobb one day old chickens were randomly allocated on floor (4 treatments X 5 pens X 10 birds): SN (standard nutrient diet), SY (standard diet with butyrate), LN (low nutrient diet) and LY (low nutrient diet with butyrate). Lactic acid was statistically higher in duodenum, jejunum and numerically and higher in ileum in SY treatment compared to LN, LY and SN (33.84 vs 19.36, 11.53 and 9.83 for duodenum; 32.95 vs 13.89, 9.27 and 2.72 for jejunum, respectively). Total SCFA followed the same distribution as lactic acid in duodenum and ileum being the interaction statistically significant with the highest values for SY, followed by LN, LY and SN. There were significant interactions in villus, mucosa and V:C ratio in jejunum, showing the highest values for LY treatment. It can be concluded that the interaction between the diet composition and addition of GUSTOR N’RGY modify bacterial fermentations, however more studies are necessary to evaluate what kind of bacteria have been affected
