The Comparison of Performance of Three Hybrid Combinations of Broiler Chicks at Different Dose of Probiotic

If we want to find replacement to use of antibiotics, we must search more naturally alternative methods. Such method can be also used with probiotics in poultry nutrition. By the help of them we can achieve better health state and higher increase of live and slaughter weight. We tested the effect of probiotic Propoul in the experiment. We applied two different doses of probiotic at three hybrid combinations broiler chicks (Ross 308, Hubbard JV, Cobb 500). We watched difference among live weight, body symmetry and feed conversation. In all hybrids we found statistically significant difference (P<0,05) between experimental groups and control group, only experimental group 2 and control group at hybrid Ross 308 we found statistically significant difference (P
