Cilj istraživanja bio je ispitati utjecaj dodatka organskih kiselina (BOLIFOR FA 2000S) u hrani na proizvodne parametre kod pilića u tovu. Pokus je proveden na 60 jednodnevnih pilića provenijence Cobb 500 podijeljenih u dvije skupine. Tijekom pokusnog razdoblja pilići su hranjeni potpunim krmnim smjesama za tov pilića (starter, grover i finišer). U smjese pokusne skupine preparat BOLIFOR FA 2000S (KK Animal Nutrition A KEMIRA GrowHow COMPANY) dodan je u količini od 6g/kg smjese u skladu s preporukama proizvođača. Pilići kontrolne skupine, hranjeni smjesama sa dodatkom preparata BOLIFOR FA 2000S, ostvarili su veću prosječnu tjelesnu masu i prirast, bolju konverziju hrane i veći proizvodni indeks na kraju tova od 42 dana. Veću prosječnu masu obrađenog trupa i veći randman mesa također su ostvarili pilići pokusne skupine. Međutim, razlike za praćene proizvodne parametre između pokusne i kontrolne skupine pilića nisu bile statistički značajne (p>0,05). Dobiveni rezultati ukazuju na to da dodatak organskih kiselina (0,6 % BOLIFOR FA 2000S) u hranu može imati pozitivne učinke na proizvodne rezultate pilića u tovu., The aim of the study was to evaluate the effects of organic acids (BOLIFOR FA 2000S) added to feed on broiler performances. The experiment was conducted on 60 chickens of Cobb 500 hybrid divided into two groups (experimental and control group). The chickens were fed three feed mixtures (starter, grower and finisher). The experimental group was fed the mixtures containing 6g/kg of BOLIFOR FA 2000S (KK Animal Nutrition A KEMIRA GrowHow COMPANY) in accordance with recommendations of the product producer. At the end of the 42 days fattening period higher average body weight and body weight gain, better feed conversion ratio and higher European Production Index- EPI were observed in broiler chickens fed diets containing 6g/kg of BOLIFOR FA 2000S. The chickens of experimental group had higher weight of carcass and carcass yield, too. However, the results showed no significant effects of diets with addition of BOLIFOR FA 2000S (P>0.05) on performance parameters. The results indicate that the supply of organic acids (0.6 % BOLIFOR FA 2000S) to broiler chickens may have a positive effect on chickens performances.

The aim of the study was to determine the effect of two different acidificants on the growth pattern of piglets during the period from weaning until the attainment of 30 kg body weight. A total of 336 pigs were included in the study, divided in two equal groups (Fra Acid, n=168; Acidad Dry®, n=168). On the basis of weaning weight, piglets were divided into “light” (L = 6 kg) and “heavy” (H = 8 kg) groups. Two acidificants, which varied in organic acid content, were used in the piglet diets. Feed was supplemented with Fra Acid at a concentration of 0.65, 0.60 and 0.40 %. The second supplement, Acidad Dry®, was added at concentrations of 0.35, 0.30 and 0.20 %. Piglets were individually weighed at weaning, on the 23rd day of age and again each time the feed was changed (at days 35, 49 and 82 of age). The experimental groups did not differ significantly in body mass during the experimental period. Piglets with Acidad Dry® achieved higher daily gains than piglets fed with Fra Acid, but again, the relationship was not statistically significant. “Heavy” piglets in the Acidad Dry® supplemented treatment had significantly higher daily gains in the period from 49 to 82 days of age in comparison to those in the Fra Acid treatment (567 ± 80g; 507 ± 140 g, p=0.044)., Cilj rada bio je odrediti djelovanje dvaju različitih acidifikanata na rast praščića u razdoblju od odbica do postizanja tjelesne mase od 30 kg. U istraživanje je bilo uključeno 336 svinja podijeljenih u dvije jednake skupine (Fra Acid, n = 168, Acidad Dry K n = 163). Na temelju tjelesne mase pri odbiću praščići su podijeljeni u "laku" (L = 6 kg) i "tešku" (H = 8 kg) skupinu. U obrocima praščića upotrijebljena su dva acidifikanta različitog sadržaja organske kiseline. U hranu je dodavan Fra Acid u koncentraciji od 0,65, 0,60 i 0,40%. Drugi dodatak, Acidad Dry K, dodavan je u koncentracijama od 0,35, 0,30 i 0,20%. Praščići su pojedinačno vagani pri odbiću, zatim 23. dana starosti i opet svaki puta kad je promijenjena hrana (35., 49. i 82. dan starosti). Pokusne skupine nisu se značajno razlikovale u tjelesnoj masi za vrijeme pokusa. Praščići s Acidad Dry K postigli su veće dnevne priraste od praščića hranjenih s Fra Acidom, ali povezanost nije bila statistički značajna. "Teški" praščići u tretmanu s Acidad Dry K imali su značajno više dnevne priraste u razdoblju od 49. do 82. dana starosti u odnosu na one u Fra Acid tretmanu (567± 80 g, 507± 140 g, p = 0.04).
