The experiments included 50 does and 36 weaned rabbits of the White New Zealand breed. The animals were divided into two groups – experimental and control. The exeprimental group was supplemented with probiotic “ZOOVIT”. The addition of “ZOOVIT” probiotic increases the fertility rate , which is 85,71 % in the experimental and 66,66% in the control group. The number of the live born rabbits is also higher in the experimental animals. In the experimental group is recorded a 10.8% lower mortality rate before weaning and a 10.9% higher average daily growth rate than in the control one. In rabbits for fattening, the experimental group has a 11.11% lower mortality rate. The additive used reliably increases live weight in the test group. Further studies are needed to establish the optimal doses of “ZOOVIT” in rabbit does, growing rabbits and rabbits for fattening.
