Comparative developmental dynamic of hens and quails caecums microbocenosis
Journal Title: Біологія тварин - Year 2014, Vol 16, Issue 4
Abstract
The implementation of high poultry performance has directly related to animal health, such as the formation of stable intestine microbocenosis. The preparation for correction the intestinal microfloras composition is appropriate to use only before the disbacteriosis occurrence at the critical periods of growth and development of poultry. The adaptation, the plumage, the molt and other stresses factors occur for the each birds type at different ages. The works objective was to investigate and compare the dynamics of the intestinal microbocenosis formation of hens and quails. The qualitative and quantitative microfloras composition of caecums contents of laying hens cross «Hayseks Brown» (1-, 6-, 30-, 60-, 90-, 120-day) and Japanese quails (1-, 7-, 28-, 42-, 70-day) were studied. The Colonies Formation Units Number (CFU) of certain microorganisms groups in gram caecum content were determined by dilutions method with sowing in elective mediums. The identification was carried out by their morphological, cultural, physiological and biochemical properties. The digital data were evaluated statistically using t-Student's test. Two critical periods of quails caecum microbocenosis formation were revealed. The first period (adaptation and plumages beginning from the 1-st to 7-th day) was characterized by a low number of lactobacteria and bifidobacteria (5–6 Log10CFU/g). These data were determined on the total absence background of pathogenic microorganisms (1-day quails), the appearance of Proteus cells (7-day quails) and it did not require the correction. The second critical period (juvenile moult in 42 days of birth) was characterized by the decrease in the number of lactobacteria, bifidobacteria and lac+ Escherichia coli strains and the increasing of the number of conditionally pathogenic bacteria. This period requires the use of probiotic preparations for the disbiosis prevention. The number of lactobacteria, bifidobacteria, Escherichia coli, Proteus and fungi in the chickens’ caecum contents was higher compared with those of the Japanese quail in all age periods. The period from first to 6 days can be considered as critical for laying hens. For this period the low numbers of lactobacteria and bifidobacteria were determined and it was found the increasing the number of Proteus and genus Candida fungi.
