Abstract:
The purpose of the research was to determine the digestibility of nutrients in the mixed fodders supplemented with the probiotic preparation "Vitacorm Bio Plus" based on Lactobacilus bacteria 1 x 107 at different levels. To achieve the goal, a digestibility test was carried on using twelve analogues gilts of two breeds (YxP), distributed into four experimental groups of three heads each (G1, G2, G3 and G4), which were kept in similar conditions. The gilts in G1 (the control group) were fed the basic mixed fodder (BMF), and the experimental animals in G2, G3 and G4 were fed mixed fodder supplemented with the probiotic preparation "Vitacorm Bio Plus" at different levels: 2.0 kg/t, 3.0 kg/t and 4.0 kg/t respectively. At the end of the trial it was determined, that during the control period the intake of mixed fodder was the lowest in the gilts in G2. It was by 4.8% lower compared to G1. It was also observed that the supplementation of the BMF with probiotic "Vitacorm Bio Plus" at the level of 2.0 kg/t increased the digestibility of nutrients in the animals in G2 compared to G1: the dry matter by 2.34% (p>0.05), the organic matter by 2,09% (p>0.10), crude ash by 5.69% (p> 0.10), crude fiber by 5.2% (p>0.001), and non-nitrogenous extractive matter by 1.96% (p>0.10). The results suggest that in order to improve the digestibility of nutrients in young pigs, the supplementation of mixed fodders with the probiotic "Vitacorm Bio Plus" should be done at the level of 2.0 kg/t.
