The use of biologically active supplements as an alternative for application of antibiotics in production of pork

Abstract

Abstract The article presents materials of scientific research of possibility of using biologically active substances as an alternative for antibiotics in production of pork. The aim of this work is to study the effect of drug for veterinary use, that contain the main functional component – NONON, in comparison with biologically active additives «Lactusil» and «Sporothermin» in feeding young pigs on their growth and development. The studies were carried out on the basis of Lenin PZK of Surovikinsky district of Volgograd Oblast from January to June 2019. For this, 4 groups of large white piglets were formed, 30 heads each at the age of 2 months. In this case, the control group received a general economic diet (GED), animals of the I group received GED in common with VD in an amount of 0.5 g (5 mg of active ingredient) per day per 1.0 kg of feed for 14 days; II groups - GED + dietary supplement «Sporothermin» in amount of 1.0 kg per ton of compound feed; Group III - GED + dietary supplement «Lactusil» - at a dose of 0.2 ml / kg of live weight. The use of probiotics in the diets in comparison with VD has shown their high efficiency on growth, development and meat productivity of gilts. It was found that animals of groups II and III in biochemical, immuno-biological indicators and meat productivity were superior to analogs from control group and I group (treated with VD).
