Abstract

The study, which included four groups of growing young pigs (each consisting of 30 animals), was arranged under conditions of the Bryansk meat-processing plant and laboratories of the Ernst Federal Research Center of Animal Husbandry. The duration of the experiment was 113 days. Animals of the group 1 (control) were fed with the SK-4, SK-5 and SK-6 mixed fodders without any probiotic additives. The Groups 2 and 3 were fed by a mixed fodder supplemented with the Enzymesporin probiotic (0.5 and 1.0 kg t-1, respectively). The Group 4 was fed by a mixed fodder supplemented with the Virginiamycin antibiotic (250 g t-1). The feeding of different concentrations of the Enzymesporin probiotic complex and Virginiamycin antibiotic to the growing young pigs of the experimental Groups 2, 3, and 4 provided the average daily liveweight gain equal to 771.4, 775.4, and 818.8 g (5.8, 6.5, and 12.2%), respectively, as compared to the control. Addition of different dosages of the probiotic complex or the antibiotic to the fodder fed to the growing young pigs (Groups 2, 3, and 4) did not result in a significant increase in the lysozyme and bactericidal activity of blood serum and the phagocytic activity, though a tendency to the phagocytic index increase was observed. Addition of the probiotic complex to forage did not provide any negative impact on the intestinal microbiocoenosis; moreover, it positively influenced on the growth of lactobacteria.

Highlights

There are four groups of biologically active substances able to increase the forage assimilation efficiency: feed antibiotics, feed enzymes, probiotics, prebiotics and synbiotics
In United States, every dollar spent for the production of feed antibiotics provides a profit equal to 2–5 dollars; feed antibiotics are used for production of ~80% of poultry, 75% of pigs and dairy cattle, and 60% of beef cattle
As an alternative to highly efficient foreign preparations, Russian scientists developed a new spore-based probiotic Enzymesporin characterized by an increased concentration of beneficial bacteria, such as Bacillus subtilis and Bacillus licheniformis

Summary

Introduction

There are four groups of biologically active substances able to increase the forage assimilation efficiency: feed antibiotics, feed enzymes, probiotics, prebiotics and synbiotics. Antibiotics from the virginiamycin group (E711) are especially important for the animal husbandry These antibiotics are used as feed additives to improve the growth of poultry, pigs and cattle (Stewart, 2010; Li et al, 2017). Virginiamycin is produced by Streptomyces virginiae and possesses a bacteriostatic activity towards Gram-positive and Gram-negative bacteria, which have the R-factor This antibiotic is included into a number of drug preparations, such as eye and ear drops, capsules and ointments. An alternative to the antibiotic use includes the use of feed supplements and preparations of the probiotic and prebiotic action (Fuller, 1998), enzyme preparations, and complex therapeutic and preventive additives intended to stimulate non-specific immunity, as well as to prevent and/or treat mixed gastrointestinal infections and digestive disorders (Roselli et al, 2017). The investigation of the efficiency of different dosages of Enzymesporin comparing to Virginiamycin in relation to feeding of growing young pigs is very interesting from the theoretical and practical point of view
