Abstract	Visoka produktivnost te učinkovita konverzija hrane kao imperativi u suvremenoj stočarskoj proizvodnji mogu se ostvariti upotrebom određenih dodataka u hranidbi životinja. Cilj ovog istraživanja bio je utvrditi utjecaj dodatka proizvoda na bazi ortofosforne kiseline u tovu hibridnih pilića, odnosno utvrditi kretanje tjelesne mase, konverziju krmne smjese i mortalitet pilića koji su u vodu za piće dobivali 0,1 i 0,2 % dodatka na bazi ortofosforne kiseline te ih usporediti sa proizvodnim rezultatima kontrolne skupine pilića. U pokusu je korišteno 120 muških jednodnevnih pilića (Ross 308) podijeljenih na tri skupine (kontrolnu skupinu pilića i dvije pokusne skupine). Nakon tova u trajanju od 42 dana i obrade prikupljenih podataka može se zaključiti da se dodatak ortofosforne kiseline u koncentraciji od 0,1 %, za razliku od dodatka u koncentraciji 0,2 %, može preporučiti u tovu hibridnih pilića pošto su se proizvodni rezultati (konverzija hrane i mortalitet) pokazali kao statistički značajno bolji u odnosu na ostale skupine u istraživanju.
Abstract (english)	High productivity and efficient feed conversion as imperatives in modern animal production can be achieved by using certain additives to animal nutrition. The aim of this study was to determine the influence of ortophosphoric acid in chicken fattening, thus to determine the change of body weight, feed conversion rate and the mortality rate of broilers that received 0.1 and 0.2 % of the ortophosphoric acid based additive in drinking water and compare them with the results of the control group. The research was conducted on 120 day-old male broilers (Ross 308) which were divided into three groups (one control group and two experimental groups). At the end of the 42 days fattening period and processing the collected data, it was shown that the addition of ortophosphoric acid based additive in concentration of 0.1 %, as opposed to concentration of 0.2 %, can be recommended in broiler fattening as the results (feed conversion rate and mortality rate) have been statistically significantly better compared to other groups in the research.
