Efficiency of the use of probiotics in comparison with antibiotics in pig breeding

Abstract

The article presents materials on the study of effect of complex of biologically active substances "Lactumin" and "Lactusil" based on lactulose as an alternative to antibiotics in diets of young pigs on state of microflora of gastrointestinal tract and the formation of productive qualities of animals. The scientific research was carried out on basis of farm-breeding plant named after Lenin of Surovikinsky District of Volgograd Region. The level of humoral immunity was assessed according to results of bactericidal activity of blood serum obtained from results of zootechnical studies. The assessment of dynamics of live weight was carried out on the basis of control weighings and the calculation of absolute and average daily gains. Control slaughter of 5 animals from each studied group was carried out according to methodology generally of All-Russian Institute of Animal Husbandry accepted in Russia. It was found that the use of studied probiotic supplements in diets of pigs promoted a higher level of metabolic processes in their bodies, improved biochemical, morphological indicators and the level of natural resistance, and also influenced in live weight and slaughter indicators.
