MICROBIOLOGICAL SAFETY OF EGG PRODUCTS WHEN USING PROBIOTIC NORD-BACT
Probiotic Nord-Bact, developed on the basis of bacteria Bacillussubtilis strains to improve the quality of egg products. Production tests werecarried out in the Yakut poultry farm in the workshop number 19 on 30 thousandlaying hens from the age of 45–46 weeks of the Rhodonite-3 cross. For theproduction tests, 3 groups of analogues of laying hens with 10 thousand animalseach were formulated: 2 experienced, 1 control. According to the results of theresearch probiotic it was revealed that after the use of the probiotic drugNord-Bact in both experimental groups, neither in the contents nor in theeggshell, the presense of conditionally pathogenic, pathogenic microorganisms,in contrast to the control group, which has a higher the content of mesophilicaerobic facultative anaerobic microorganism, the presease of conditionally pathogenicmicroorganisms Protea, toxigenic fungi Aspergillus spp., as well as potential lactoseenterepathogenic atelnyh Echerichia. Therefore after the use probioticNord-Bact, microbiological safety of egg products in ensured. The results ofbiochemical studies after the use of probiotic Nord-Bact show an increase in contentof calcium, magnesium in eggshells by 31 %, phosphorus by 23 %,compared with the control. A significant increase in iron and vitamin A eggs inthe yolk by 12 %, sodium and, magnesium by 10 %, potassium by 6 %,and calcium by 1,5 % was noted. Thus, after the application of probioticNord-Bact in the yolk, protein, shell, the content of vital minerals andvitamins significantly increases. The use probiotic Nord-Bact not only had apositive effect on microbiological, biochemical indicators of eggs, but alsoreduced egg production (by 1,4 %), contamination (4,7 %)), increasedproductivity (4 %), compared to similar workshop, where did not use thedrug.
