GUSTOR N’RGY and Nutrients Concentration in Broilers

The study, presented in IPSF 2016, compared the effect of sodium butyrate protected with PFAD sodium salt (GUSTOR N’RGY) with different diets on growth performance. A 2×2 factorial design was used with two basal diets based on wheat, barley and soy: S (standard diet) and L (low nutrient diet: – 60 Kcal/Kg 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 diet with butyrate). The addition of protected butyrate showed animals achieved (P<0.05) higher final BW with higher ADG at 21 d than those without additive (0.807 vs 0.773 Kg and 35.83 vs 34.18 g/d). Also, tended to present better FCR (1.271 vs 1.305) (0-21 d) and numerically in the total period (0-42d) (1.547 vs 1.579). Treatment with low energy and butyrate (LY) had higher FBW (2.34 Kg) and ADG (54.34 g/d) than SN (2.29 Kg and 53.27 g/d). We can conclude that the addition of GUSTOR N’RGY at early stages improves performance results in broilers. On the other hand in this trial, broilers fed with low nutrient diet (- 60 Kcal/Kg and – 2.3% AA) and 1 Kg/t of GUSTOR N’RGY obtained the same FBW than standard diet with 2% improvement of FCR.
