The most important aspect of broiler production is feeding, whose costs represent about 70% of total costs. Thus, the growth of poultry production has been based on a strong consumer demand for products that are cheap, safe, and healthy. That kind of product is old bread, whose return from the store represent a problem for its remediation. For the use of the old bread as a feed, the European Union has promulgated a series of regulations and directives, which order a ban on its utilization without prior treatment. The most common treatments are pelleting and extrusion. In poultry, the upper limit for the use of the old bread in feedstuff is often prescribed and amounts to 15%. The aim of this paper was to determine a possibility to use 5 and 10% old brown pelleted bread in feed mixtures for broilers fattening. The study has shown that the addition of old bread significantly improves broiler production indicators. The best results and a more favorable ratio of omega 6 and omega 3 fatty acids in the chicken muscles were obtained in the group fed with a 10‐percent share of old brown bread (p<0.05). Such a processed old bread can be used as a new ingredient in animal feed production as a partial replacement for maize component. Najvažniji aspekt proizvodnje brojlera jest hranidba, čiji troškovi čine oko 70% ukupnih troškova proizvodnje. Tako se rast peradarske proizvodnje temelji na snažnoj potražnji potrošača za proizvodima koji su jeftini, sigurni i zdravi. Takav je proizvod stari kruh, čije vraćanje iz trgovine predstavlja problem sanacije. Za korištenje staroga kruha kao hrane za životinje Europska unija donijela je niz propisa i smjernica kojima se propisuje zabrana korištenja bez prethodne dorade. Najčešći tretmani su peletiranje i ekstruzija. Kod peradi je često propisana gornja granica za uporabu staroga kruha u hrani za životinje, a ona iznosi 15%. Cilj ovoga rada bio je utvrditi mogućnost korištenja 5 i 10% staroga crnog peletiranog kruha u krmnim smjesama za tov brojlera. Istraživanje je pokazalo da dodavanje staroga kruha značajno poboljšava proizvodne pokazatelje brojlera. Najbolji rezultati i povoljniji omjer omega 6 i omega 3 masnih kiselina u pilećem mišiću dobiveni su u skupini koja se hranila s 10% udjela staroga crnog kruha (p<0,05). Takav obrađeni stari kruh može se koristiti kao novi sastojak u proizvodnji hrane za životinje kao djelomična zamjena za kukuruznu komponentu.
