Reviewing the possibility of the substitution of antibiotics with probiotics in diet for weaned piglets

Abstract

The effects of the use of antibiotics and probiotics in the nutrition of weaned piglets were examined. The trial was conducted on 36 piglets divided into two groups during the entire investigation period. In the first study period, a feed mixture with 20% protein was used, while in the second period, a mixture with 18% protein. The first group, control, was fed with mixtures containing antibiotics in the amount of 0.2%, while the experimental group was fed with mixtures containing probiotic in the concentration of 0.03%. The obtained results showed that the use of probiotics, instead of antibiotics, resulted in the increase of gain by 4.09%, as well as food conversion ratio by 5.37% during the entire research period, while the cost was reduced by 6.48% per kilogram of gain.

Ispitivani su uticaji korišćenja antibiotika i probiotika u ishrani zalučene prasadi. Ogled je sproveden na 36 prasadi podeljenih na dve grupe tokom celog perioda istraživanja. U prvom periodu istraživanja korišćena je smeša hraniva sa 20% proteina, dok je u drugom korišćena smeša sa 18% proteina. Prva kontrolna grupa je hranjena smešama sa antibiotikom u količini od 0,2%, dok je ogledna grupa hranjena smešama sa probiotikom u koncetraciji od 0,03%. Dobijeni rezultati su pokazali da korišćenjem probiotika, umesto antibiotika, dolazi do poboljšanja prirasta za 4,09%, kao i konverzije hrane za 5,37% u toku celog perioda istraživanja, dok je cena koštanja smanjena za 6,48% po kilogramu prirasta.
