Influence of bee products on intestinal microbiota formation in healthy birds and birds with candidiasis

Candidamycosis causes significant damage to the poultry industry. Mortality rate in young birds reaches 95100 %. The aim of the study was to optimize formation and intestinal colonization resistance under the influence of biologically active bee products (BABP) and the features of recovery in birds infected with candidamycosis of digestive tract (CDT). Studies were carried out on Japanese meat 10-day-old to 90-day-old quails. All the studied beekeeping products extracts of wax moth, drone homogenate and propolis contribute to the stabilization of the hidden genetically laid down mechanisms of natural intestinal microbiocenosis in healthy quails bred in captivity, without causing damage to the body, restoring the balance of normoflora and opportunistic pathogenic microorganisms to physiological values. However, a constant complex of stressors encountered during bird breeding, associated with the conditions of keeping, feeding, veterinary and zootechnical measures, lead to a significant activation of Candida albicans in large intestine, with the subsequent development of candidiasis of digestive tract, deep dysbacterioses, characterized by increased reproduction and increase in the content of opportunistic pathogenic microorganisms: Candida albicans by 8.34 times, Staphylococcus aureus by 4.37 times, Pseudomonas spp. by 3.29 times; inhibition of reproduction and decrease in the level of normoflora: Lactobacillus spp. by 6.0 times, Bifidobacterium spp. by 7.25 times. The use of extracts of wax moth, drone homogenate and propolis in candidamycosis-i nfected birds contributed to restoration of quail intestinal microbiocenosis, which was manifested by: a) decrease in the level of opportunistic pathogenic Candida albicans by 3.3; 4.61 and 3.97 times; Staphylococcus aureus by 4.0; 7.78 and 4.5 times; Pseudomonas spp. by 3.05; 5.32 and 3.96 times; b) activation and increase of normoflora: Lactobacillus spp. by 6.38; 10.0 and 8.84 times; Bifidobacterium spp. by 5.36; 8.42 and 7.5 times.
