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.
