Application of alternative growth promoters in broiler production

Abstract

Subsequent to banning of use of antibiotics as growth promoter sin poultry nutrition, numerous studies turned to finding of alternative solutions, i.e. other, natural substances, which would have positive effect on chicken growth and feed conversion. Today, several groups of these additives are in use, and most often probiotics, prebiotics, enzymes, acidifiers, antioxidants and phytogene additives. Considering that each of the stated groups has its own specificities, objective of this work was to present main mechanism of their action and to present their effect on production results in fattening of broiler chickens through review of research published in this field.

Nakon zabrane upotrebe antibiotika kao promotera porasta u ishrani živine, veliki broj istraživanja okrenut je upravo iznalaženju alternativnih rešenja, odnosno nekih drugih, prirodnih supstanci koje će imati pozitivan efekat na prirast pilića i konverziju hrane. Danas je u upotrebi više grupa ovih aditiva, a najčešće se koriste probiotici, prebiotici, enzimi, zakišeljivači, antioksidanti i fitogeni aditivi. S obzirom na to da svaka od navedenih grupa ima svoje specifičnosti, cilj ovoga rada je da prikaže osnovni mehanizam njihovog delovanja i da kroz pregled novijih istraživanja iz ove oblasti prikaže njihov efekat na proizvodne rezultate u tovu brojlerskih pilića.
