UPOTREBA PROPOLISA U HRANIDBI PILIĆA: POSTOJI LI POTENCIJAL ZA STVA-RANJE FUNKCIONALNE HRANE?

Zbog svojih svojstava propolis se smatra funkcionalnom hranom. Budući je upotreba propolisa u preh-rani ljudi ograničena, treba ju povećati kroz konzumaciju namirnica obogaćenih propolisom koje se uče-stalo koriste u prehrani, poput pilećeg mesa. Cilj ovog istraživanja bio je utvrditi utjecaj dodatka propo-lisa hranidbi pilića na tjelesnu masu pilića, masu trupova pilića i randman, kao i na masu pojedinih dije-lova trupa (prsa, batkovi sa zabatcima, leđa sa zdjelicom, krila i vratovi) kao pokazatelja mogućnosti uporabe propolisa u hranidbi tovnih pilića i moguće proizvodnje obogaćenog pilećeg mesa. Istraživanje je provedeno na 180 pilića Ross 308 provenijencije podjednako raspoređenih prema spolu i podijeljenih u tri skupine: kontrolnu skupinu pilića (K) koja je hranjena standardnom krmnom smjesom i dvije eks-perimentalne skupine pilića (E) hranjene uz dodatak propolisa u dvije različite koncentracije ( E1 2 g / kg i E2 4 g / kg). Istraživanje je pokazalo kako nisu postojale statistički značajne razlike između skupina K i E s obzirom na tjelesnu masu i potrošnju hrane u bilo kojem tjednu pokusa. Istraživanje je nadalje otkrilo kako nije bilo statistički značajnih razlika u masi trupova pilića, randmanima i masi pojedinih dijelova trupa između skupina K i E. Može se zaključiti kako dodavanje propolisa nije rezultiralo statis-tički značajnim razlikama u istraživanim proizvodnim pokazateljima pilića. Kako bi se bolje procijenila mogućnost stvaranja propolisom obogaćenog pilećeg mesa potrebna je dodatna analiza drugih pokaza-telja.
Due to its properties, propolis is considered a functional food. Since the use of propolis in the human diet is restricted, it needs to be increased by consumption of propolis enriched foodstuffs that are common in the diet such as chicken meat. The aim of this study was to determine the influence of die-tary supplementation with propolis on the chickens’ body weight, the carcass body weight of slaugh-tered chickens and carcass yield as well as carcass body parts weight (breasts, drumsticks with thighs, backs with pelvis, wings and necks) as indicators of the use of propolis in the feeding of chickens and the possible production of enriched chicken meat. The study was conducted on 180 Ross 308 chickens equally distributed by sex and divided into three groups: the control group of chickens (C) fed with a basal diet and two experimental groups of chickens (E) fed with the same diet supplemented with propolis (E1 2 g/kg and E2 4 g/kg). The study showed that there were no statistically significant dif-ferences between C and E considering body weights and feed consumption in any week of the feeding trial. Study further revealed that there were no statistically significant differences in carcass body weights of slaughtered chickens, carcass yields and carcass body parts weight between C and E. It can be con-cluded that propolis addition did not result in statistically significant differences in evaluated perfor-mance indicators of chickens. In order to better evaluate the possibility of creation of the propolis en-riched chicken meat analysis of different parameters are needed.
