Supplementation of Purple Sweet Potato Extract on Protein Digestibility and Meat Protein Mass in Broiler Reared Under Different Cage Density

Abstract


The research was conducted to evaluate supplemental effect of purple sweet potato extract (PSPE) on protein intake, ileum protein digestibility and meat protein mass. The experiment was assigned in a randomized complete design with 2×3 factorial scheme, 6 treatments and 4 replications. The first factor was cage density (normal density/D1 = 8 birds/m2 and high density/D2 = 16 birds/m2), and the second factor was the extract levels of purple sweet potato (A0 = control diet, A1 = diet containing 25 ml PSPE/kg feed and A2 = diet containing 50 ml PSPE/kg feed). Birds were kept in a brooder cage for 14 days and then transferred to colony cages (1×1 m) until the age of 35 days. When measurement of protein digestibility the birds were moved to individual battery cage on day 35. The experimental feed contained 21% crude protein and metabolizable energy of 3000 kcal/kg. The results showed that the extract of purple sweet potato and cage density did not show significant (P>0.05) interaction. The supplementation of purple sweet potato extract significantly (P<0.05) affected protein intake, protein digestibility and meat protein mass, while the cage density affected only the protein digestibility.
