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

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).

Organic pig farming as part of green economy

“…With the introduction of organic acids, an acidic environment is created (pH = 5-5.5), in which pathogenic microorganisms die, and beneficial microflora and lactic acid bacteria develop normally, suppressing pathogens. At the same time, the acidic environment increases the activity of digestive enzymes by 2-2.5 times, which improves the digestibility of feed [21,22]. The introduction of acids accelerates the process of protein breakdown, increasing the digestive activity and growth rate of young pigs.…”

Improving the quality of broiler chicken meat without the use of antibiotics

“…Ultimately, due to biomagnification, such drugs accumulate in human body, that increases risk of spread of pathogenic microorganisms, bacteria and viruses resistant to many types of antibiotics. That is why today the question of the use of antibiotic therapy in the practice of poultry farming to prevent various infections remains controversial, and the search of alternatives to these substances is becoming actual topic for research [2,3,4,5].…”

Influence of the innovative prebiotic complex on physiological state of pigs and quality indicators of pork

“…A small amount of lactulose -0.25-2.00% of feed weight, can be absorbed in the gastrointestinal tract, causing an immunological effect. Recent studies carried out on rats have shown a positive effect of lactulose on the absorption of calcium and magnesium [13,[23][24][25][26][27][28][29][30][31].…”

“…Thus, the foregoing indicates that lactulose-based feed additives are promising and effective dietary correctors for farm animals. Such feed additives are being actively studied from the viewpoint of improving productivity of pigs and in-vivo formation of consumer properties of meat [30][31][32][33][34]. This is especially important in light of achieving the country's food security, which, of course, is a strategic task facing agro-industrial complex of the Russian Federation [35][36][37][38][39][40][41][42][43][44].…”
