In addition, a month before the introduction of rams into the flock, melatonin and progesterone hormones had been added to the barley and corn bulgur gruel in the form of a powder and were given to ewes, and the percentage of estrus and lambing was studied. At the same time, the specific features of the Balbas sheep breeds, the percentage of lambing among ewes fed with different feed ratios, and the live weight of the newborn twin lambs in groups were also analyzed.

K Abstract: In the presented article, experiments for determination of antibacterial properties of the strains Bacillus Cereus ATCC 14579 and Bacillus Subtilis ATCC 6633 and, therefore, their ability to secrete bacteriocins, was subscribed. There are many trials performed for choosing the most affordable, the least time-consumable and the most appropriate method for obtaining bacteriocins from those strains. Possibility of adaptation, the synthesis way to conditions of a factory production was analysed. During that, research productivities of processes such as filtration, pasteurisation, and scrolling in a centrifuge of the bacterial suspensions were comprised. Usage of supernatant, obtained after long-lasting centrifugation of the bacterial suspensions, prepared after 72 incubation of the bacteria was received as most suitable for obtaining of the biologically active metabolites. Additionally, during the experiments, incidentally, was discovered, that both Bacillus bacteria strains from fresh 24 hours culture and old 72 hours culture isolates differ in morphology signs. This may, generally, contributes to the emergence of a new approach to the study of the morphology of other “young” and “old” bacteria.

In morphometric study by principal component analysis 32 colonies were grouped in big cluster. ANOVA analyses showed significantly different among 4 groups of honeybees for most studied traits characters. Total of 488 bases in COI-COII region, 981 bases in COI region and 425 bases were obtained after trimming in partial CYT B region. This investigation showed that variation mtDNA regions can be used for the characterization of Azerbaijan honeybees.

Both excess as well as deficiency of thyroid hormones lead to disturbance of bone metabolism. Consequently, the disorder of bone formation and bone resorption phases can cause loss of bone mass and fractures. The aim of this study is to investigate better markers of bone metabolism pathologies during thyroid disfunction.
