Effects of Prebiotics on the Production Performance of Broiler Chickens

Abstract

The paper presents results of investigating effects of using prebiotic preparation Bio-Mos, a manan-oligosacharide in a diet of fattening chickens. Chickens were divided into three groups and fed diets that were balanced and differed only in mentioned prebiotic’s level. Control group of chickens obtained diet of standard content without added prebiotic while in diets of the ned`t two groups of chickens prebiotic was added and its concentration in the first mid`ture was 0.05% and in the second 0.10%. During the 42 days of experiment data of weight gain and feed consumption were collected. Ending results of that experiment showed 7.11% and 7.92% increased weight gain of two experimental group of chickens, respectively, comparing them to the control group. Regarding feed conversion ratio improvement of 5.21% and 5.26% was registered. Summarizing the results of investigation it is possible to determine positive effect of prebiotic on the production results in broiler chickens as well as reasonableness of using it particularly insight demand of reduction and discontinuance of using antibiotics in livestock feed.

U radu se daje prikaz rezultata istraživanja efekata korišćenja prebiotskog preparata manan-oligosaharida u obroku tovnih pilića. Pilići su podeljena u tri grupe i hranjeni su obrocima koji su bili izbalansirani i razlikovali se samo u nivou prebiotika. Kontrolna grupa pilića dobijala je obrok standardnog sastava bez dodatog prebiotika, dok je u obrok sledeće dve ogledne grupe pilića dodat prebiotik, čija je koncentracija u prvoj smeši iznosila 0,05%, a u drugoj 0,10%. Tokom 42 dana trajanja ogleda praćeni su rezultati prirasta i utroška hrane. Završni rezultati ogleda u pogledu prirasta, pokazali su povećanje od 7.11%, odnosno 7.92%, dveju oglednih grupa pilića, u odnosu na kontrolnu grupu. U pogledu konverzije hrane, zabeleženo je poboljšanje od 5,21%, odnosno 5.26%. Posmatrajući rezultate ogleda, može se konstatovati pozitivan efekat prebiotika, manan-oligosaharida na proizvodne rezultate u tovu pilića, kao i opravdanost upotrebe, naročito imajući u vidu potrebu za eliminacijom antibiotika u stočnoj hrani.
