摘要: The objective of this research was to compare the effect different nutritional recommendations on performance and economics production broiler chickens. A total 1,200 Cobb-500 line male broilers were placed in a completely randomized design with four treatments 10 replicates, 30 animals each. diets each treatment as follows: 1. COBB-VANTRESS (2009); 2. Commercial feed; 3. Rostagno et al. (2005); 4. (2011). following traits evaluated: feed intake (FI), weight gain (WG), body (BW), conversion (FC) productive efficiency index (PEI). experiment ran while chickens 1 21 42 days old. For economic analysis, diet cost live price considered when calculating average (ADC) gross trading margin (TM). Analysis variance used evaluate ADC TM traits; means compared Tukey’s test. In day period, there higher FI less efficient FC more PEI During 1, 3 4 had highest BW, WG PEI. show similar results, i.e., commercial being attractive producers. entire experimental (2009), (2005) (2011) for production.
