Precision nutrition is way and tools to best targets the goal of production. In poultry, especially broiler production, nowadays the goal is not only the maximal production or profit, but optimal production regarding economic and environmental aspects, resource and nature conservation - sustainable production. Simply, the precise nutrition for broilers has a new goal: to ensure that nutrients from feed, as much as possible, end in the meat and less in the manure. In order to consider the actual situation in Serbia, biological trial was performed. Quality of 8 different feeding programs was tested from the beginning of broiler fattening to the end (6 market/commercial nutrition programs and 2 control programs). In total, 18 different mixtures of 4 different commercial manufacturers and 6 control mixtures produced by the Institute for Animal Husbandry were tested. Total of 3520 one-day old broiler chickens of Cobb 500 hybrid were used, housed in 32 boxes according to the trial plan. Complete analysis of the chemical and microbiological composition of every diet used in the test was performed and broiler production performance observed during 42 days of fattening. The results show that the nutritional quality of complete feed mixtures for broilers available on Serbian market, varies significantly among different programs and different manufacturers, and consequently also the economic and ecological aspects of using such feed. There are many things that can be improved to achieve the new goal, from relatively simple things to “fine-tuning“.
