Abstract


This study aimed to evaluate crude corn oil with high acidity (CCOHA) as a surrogate for degummed soybean oil (DSO) in broiler diets. The design was completely randomized, with four treatments and ten replicates. Each box contained 40 birds (male), totaling 1600 Cobb Slow birds. Treatments consisted of two sorghum-based diets, one with DSO (SSO) another with CCOHA (SCO), and two corn-based diets, one with DSO (CSO) another with CCOHA (CCO). At 30 days of age, a digestibility test was performed using total excreta collection to determine apparent metabolizable energy (AME) and nitrogen-corrected AME (AMEn) from test rations. At 42 days of age, we evaluated live weight (LW), feed intake (FI), feed conversion (FC), carcass yield (CY), and the yields of breast with bone and skin (BWBS), skinless boneless breast (SBB), thigh (T), drumstick (D), and wing (W), as well as breast centesimal composition. Neither corn nor sorghum-based diets with CCOHA showed differences between AME and AMEn. Both DSO and CCOHA diets showed no differences in LW, FI, FC, carcass and cuts yields when using CCOHA. Regarding breast composition, no differences in dry matter and in the levels of crude protein, fat, and mineral matter were observed. We may conclude that CCOHA had no effect on the performance variables, carcass and cuts yields, and broiler meat quality.
