EFFECT OF ACIDIFIER «AKVASAN» ON INTESTINAL MICROBIOCENOSIS OF BROILER CHICKENS

Introduction. In recent years, there has been an increase in the use of organic acids in poultry fattening as antibiotic substitutes due to the increase of a microorganism’s resistance to antimicrobial preparations and the consequences for human health.

The goal of the work was to study the effect of the acidifier «Akvasan» on intestinal microbiocenosis of growing broiler chickens.

Materials and methods. The research was conducted on three groups of the broiler chickens of a line Ross 308 (two thousand birds in each). The chickens of a control group received only feed. The chickens of the second experimental group, in addition to the complete feed, were given the liquid acidifier «FEEDACID MAX L», and the third experimental group’s chickens – the new acidifier «Akvasan» in the volume 1 liter per tonne of water.

Results of research and discussion. It was established that the amount of useful autochthonous microflora increased by an order of magnitude via drinking the drug «Akvasan». The number of microorganisms of the genus Enterococcus, Staphylococcus and fungi after giving of the acidifier «Akvasan» decreased by two orders of magnitude in the large intestine, in 43.3, 45.8 and 18.4 times (p≤ 0.001), respectively. Including the new acidifier «Akvasan» in the water lead to decreasing of the opportunistic bacteria in the intestinal microbiocenosis of the chickens in third experimental group in 2 times (p≤ 0.001), and E. coli microorganisms – in 26.3 times (p≤ 0.001), which suggests that the 0.1% solution of the «Akvasan» had bactericidal properties. S. aureus pathogenic microorganisms were not isolated in the intestine after use of both acidic substances. It was found that the acidifier «Akvasan» showed a similar effect on the chicken’s intestinal microflora as its analogue “FEEDACID MAX L” and even slightly above it.

Conclusions and prospects for further research: 1. The amount of autochthonous microflora (bifidobacteria, lactobacillus) in the large intestine of broiler chickens increased in 7.8−39.6 times (p≤0.001), while the number of microorganisms of the genus Streptococcus decreased in 2.1 times (p≤0.001). 2. It was established that the use of the acidifier «Akvasan» in chickens reduce the number of opportunistic bacteria in the intestinal microbiocenosis in 2−26.3 times (р≤0,001) and the natural release from pathogenic bacteria S. aureus. The influence of the acidifier «Akvasan» on the meat quality of broiler chickens in fattening will be studied.

Keywords: broiler chickens, the acidifier “Akvasan”, application, intestinal microbiocenosis.
