Introduction

Increasing the efficiency of pork production involves a number of interrelated components, above all, to create comfortable living conditions and the organization of full feeding of animals that have a significant influence on the formation of their high efficiency [1, 2].

Probiotics favorably to antibiotics that have no side effects, do not accumulate in the organs and tissues of animals that are not addictive by pathogenic and do not pollute the environment [3, 4, 5].

Material and methods

Preliminary safety and dose probiotic "Vitafort" based on the antagonistic bacteria B. subtilis strain 11B is set on the basis of experimental data obtained in the experimental laboratory animals (albino mice) in which non-pathogenic and non-toxic to the body dose was 10⁹ colony forming units (CFU) per animal. The initial dosage of probiotics for animals 10⁸ CFU, which was contained in a 0.1 ml of a liquid suspension, set designers drug NPP "Biofort" [3].

Selection of pigs in the group carried out on the basis of pairs of analog grown in the same conditions, feeding and [2]. It was formed five groups: group 1 (control), group 2 (probiotic "Vetom" - 1.5 g), group 3 (probiotic "Vitafort" - 0.05 ml), group 4 ("Vitafort" - 0.5 mL) and group 5 ("Vitafort" - 1 mL). Daily doses of probiotics are feeding per 10 kg of body weight of weaned piglets. Duration of the experiment was 60 days.

Results

Based on these data it became apparent, average daily gain in weaned piglets fourth experimental group was on average 21.5% higher than in the normal control group (P <0.01) and 12.4 % higher than in the second control group with the probiotic Vetom (P <0.05).

Blood tests showed that the morphological and biochemical parameters of animals of all groups were within the physiological range.

Within normal physiological changes observed for variables such as the amount of total protein (group 4 84.3 g/l to 70 g/l in normal controls), calcium (group 4 3.2 mmol/l vs. 2.6 mmol/l in normal controls), inorganic phosphorus (group 4 1.8 mmol/l vs. 1.3 mmol/l in the normal control) and urea (4 group, 3.5 mmol/l vs. 3.9 mmol/l normal controls). The differences were significant at a threshold of reliability P <0.05.

Studies have shown that the use of probiotic Vetom a dose of 1.5 mg per 10 kg of body weight in the diets of weaned piglets contributed significantly improved the digestibility of crude protein (75.6 instead of 73.0% in controls), and the use of probiotics Vitafort at 0.5 ml per 10 kg of body weight - improve the digestibility of crude protein (78.2 instead of 73.0% in controls) and NFE digestibility (92.4 instead of 87.3% in controls). In terms of digestibility of nutrients between the groups of weaned piglets using probiotics Vetom and Vitafort significant difference has been established.

Analyzing data on nitrogen balance should be noted that it weaned piglets in all groups was positive. In absolute numbers in the body of animals in the control group with probiotic delayed Vetom 20.44 g, fourth test group with probiotic Vitafort - 22.05 g and a control group of animals - 18.96 g, the difference is significant (P <0.05).

The utilization of nitrogen in all groups were consistent with the coefficients of digestibility of protein and increase in average daily gain of weaned piglets (fourth experimental group) by 21.5% compared to the control group and by 12.4% compared with the probiotic Vetom.

The balance of calcium and phosphorus in the body of weaned piglets the control and experimental groups was positive and amounted to a control group, respectively, 6.06 and 5.22 g in control with Vetom - 6.58 and 5.40 g in the fourth test - 7.05 and 5.50 g, the difference is also significant (P <0.05).

Conclusions

Inclusion in the diet for 60 days Vitafort probiotic dose of 0.5 ml per 10 kg body weight is effective and appropriate measure for growing weaned piglets.
