Uporedna analiza proizvodnih i ekonomskih pokazatelja u intenzivnoj proizvodnji kalifornijske pastrmke (Oncorhynchus mykiss) hranjene obrocima različitog sastava

This paper evaluates the effects of two different feeds on production results and economic performance in the rainbow trout (Oncorhynchus mykiss) farming. The first group (O-1) was fed with a standard complete pelleted feed, and the second group (O-2) was fed with combined feed consisting of 75 % pellets and 25 % of sardines. Better results were obtained with the O-2 group, while the O-1 group achieved results characteristic for local farming conditions and feed quality. Experimental group O-2 had significantly higher (p lt 0,01) growth rate when compared to group O-1. Considering current feed and final product (fish) prices in the market, better results in terms of cost-effectiveness were obtained (E>0,00) in O-2 group of trout fed with the combined meal. U radu je ispitivan uticaj ishrane kalifornijske pastrmke (Oncorhynchus mykiss) sa dva obroka različitog sastava na proizvodno-ekonomske rezultate. Eksperiment je postavljen sa dve grupe kalifornijske pastrmke: O-1 hra- njena je standardnom kompletnom peletiranom hranom i O-2 koja je hranjena kombinovanim obrokom. Bolji rezultat je ostvaren kod O-2 grupe, dok je O-1 grupa postigla rezultate karakteristične za kvalitet domaće hrane i uslove držanja u našoj zemlji. Ogledna grupa O-2 imala je signifikantno veći (p lt 0,01) ukupni prirast u odnosu na O-1. Pri važećim tržišnim cenama hraniva i konzumne ribe kao finalnog proizvoda, bolji ekonomski rezultati (E=2,06) postignuti su korišćenjem kombinovanog obroka kod O-2 grupe. .
