Key questions for a local broiler farm are: which broiler hybrid to rear and which industrial feed to use? To show how farmers can manage them, a combination of biological tests and feed characterizations of the most commonly used hybrids and broiler feeds in the local (Serbian) market was designed and performed. The hybrids Cobb 500 and Ross 308 were used, as well as feed of the same quality category from three established domestic producers (A, B, and C) available in the market. A factorial trial (2 3) was performed on a total of 1800 unsexed day-old chicks divided into six experimental treatments, with six repetitions per treatment and 50 chickens in each repetition. Prior to and after the biological trial, the feed was characterized. The results confirm the equally high production potential of the two tested fast-growing hybrids, the different quality of the three industrial feeds, and that for the expression of genetic potential, each feeding and fattening period was equally valuable. A complete picture of the tested feeds was obtained within a suitable posttest feed characterization with a farm economy included in the analysis, and the results differed in different production and market scenarios, which allows for finding the optimal feed for the local farm.
