Abstract
The aim of the research was to study the effect of different levels of supplementation with "Vitakorm-Bio" complex probiotic of mixed fodder in the growth, nutrient digestibility and microbial content in the feces of growing pigs. In order to conduct the trial, twelve piglets of Landrace breed were selected at the Enterprise "Moldsuinhibrid" on the basis of analogies, taking into account the origin, age, body weight and growth energy. Four experimental groups of three head each were created. The dietary treatment included: 1) CG (main diet); 2) EG1 (main diet + complex probiotic 1.5 kg/t); 3) EG2 (main diet + complex probiotic 3.0 kg/t); 4) EG3 (main diet + complex probiotic 4.5 kg/t). It was established that the supplementation of the mixed fodder for the piglets in the experimental groups with the complex probiotic "Vitakorm-Bio" had a positive impact on the growth of their body weight, which was the highest in EG2 and EG3, in which the pigs received the preparation at the level 3.0 and 4.5 kg/t, whereas the average daily gain during the whole trial was the highest in group EG2, where the level of the supplementation was of 3.0 kg/t (0.248 kg, by 2.48% higher than in the CG). The supplementation with the complex probiotic at the level of 4.5 kg/t of the diet for the gilts in EG3 helped to improve the digestibility of the organic and dry substances, crude protein, fiber and ash which were higher in comparison with CG by 0.69, 0.05, 1.92, 0.71 and 7.42% respectively. The comparative analysis of fecal matter on content of pathogenic organisms at the beginning and the end of trial revealed no significant effect under the influence of additives synbiotics.
