Technology rejection from antibiotics in pig breeding through the use of probiotics
Abstract
The article presents innovative technology development results of introduction of lactulose-containing probiotics for pig feeding. The purpose of the work is to study combined effect of biologically active additives «Lactumin» and «Lactusil» in comparison with drug for veterinary use (DP) in feeding young pigs on physiological state and productivity of animals. The scientific research was carried out on basis of farm-breeding plant named after Lenin of Surovikinsky District of Volgograd Region from January 2019 to June 2019. For this, 4 groups of large white piglets were formed. Each group consisted of 30 animals of two months old animals. Animals of the control group received a general economic diet (GED); analogues of experimental group I - GED + DP at a dosage of 6 mg per 1 kg of animal weight within 14 days; II experimental group - GED + a mixture of dietary supplements «Lactumin» and «Lactusil» at a dosage of 0.2 mg / kg of live weight each. In general, the use of biologically active additives «Lactumin» in common with «Lactusil» in diet of farm animals in comparison with DP did not have a negative effect on physiological state and level of humoral immunity. At the same time, the highest indicators of humoral immunity were found in animals of II experimental group, that received feed additive «Lactumin».
