Introduction
One aim of the study was to evaluate the impact when added to feed of the two potentially probiotic strains of lactic acid bacteria (LAB)
Material and Methods
A total of 500 one-day-old Ross 308 chicks were divided into four groups. The experimental factor was the admixture of bacterial preparation to the feed at different doses: the recommended maximum dose, a dose ten times higher, the recommended minimum dose, and a zero dose for the control group not receiving bacteria.
Results
Addition of bacteria to the diets did not have a significant effect on the final body weight, final body weight gain, nor total feed intake or feed conversion. However, lactic acid bacteria had a positive effect on chicken health. Mortality among chickens fed with LAB was reduced. Moreover, LAB feeding inhibited the growth of
Conclusion
Feeding chicken broilers with two potentially probiotic LAB strains is safe and impacts animal health positively.
