Evaluation of selenium content in eggs of domestic hen (Gallus gallus f. Domesticus) from domestic manufacturers from different regions of Russia

AbstractThe predominant frequency, rate of clucking and intensity of the maternal cluck vocalization of the broody hen (Gallus gallus) are described. The frequency, rate of clucking, and level of intensity of the cluck vocalizations were altered independently of each other. Three-day-old chicks were given a simultaneous choice test between the normal and an altered cluck or between the two altered clucks in a 'T' shaped simultaneous choice test apparatus. No significant preferences were found when the frequency was increased or decreased by 25% (Experiment 1A) but the chicks significantly prefer the normal cluck over a cluck with a 33% increase in frequency. The preference for the normal cluck over the 33% decrease in frequency was nearly significant (Experiment 1B). Thus, there exists an optimal frequency range for the maternal cluck vocalization of the domestic hen. When the rate of clucking was increased or decreased by 25% the chicks preferred the higher rate of clucking in all conditions (Experiment 2). However, the highest rate of clucking used in this experiment was close to that of the normal cluck. When the intensity was increased or decreased by 100% no significant preferences were found in any choice test (Experiment 3). This contrasts with earlier findings possibly due to a methodological difference.

Domestic Hen

Hierarchical (> 8 mm) and post-ovulatory follicles from the ovaries of laying hens at 45 and 86 weeks of age were assigned to clusters defined by the coalescence of their follicular stalks. They were also classified by size to give the succession in which ovulation had occurred, or would occur for the hierarchical follicles. The association between the order of ovulation and the observed clusters was compared with randomness and with dependence on the cluster in which the immediately preceding ovulation occurred. The order of ovulation was associated randomly with clusters, and was independent of the cluster containing the preceding ovulation. Many perceived clusters of successive follicles and post-ovulatory follicles may be compatible with a random order of ovulation. These findings do not support theories of stimulation or inhibition of adjacent follicles, leading to eventual ovulation, by a dominant follicle.

The paper identifies and assesses the closeness of the connection between incremental indicators of the financial development in the regions of Russia with the incremental regional GDP and the investment in fixed capital. It is shown that the positioning of the region as an independent participant of public debt market matters: the regional GDP and investment in fixed capital grow more rapidly in the regions which are regularly borrowing on the sub-federal bonds market. The paper also demonstrates that the poorly developed financial system in some regions have caused the imperfection of the growth mechanisms since the economy is not able to use the financial system’s functions.

Well-established results indicate that export diversification might be a better growth strategy for an emerging economy as long as its GDP per capita level is smaller than an empirically defined threshold. As average incomes in Russian regions are likely to be far below the threshold, it might be important to estimate their diversification potential. The paper discusses the Atlas of economic complexity for Russian regions created to visualize regional export baskets, to estimate their complexity and evaluate regional export potential. The paper’s results are consistent with previous findings: the complexity of export is substantially higher and diversification potential is larger in western and central regions of Russia. Their export potential might become larger if western and central regions, first, try to join global value added chains and second, cooperate and develop joint diversification strategies. Northern and eastern regions are by contrast much less complex and their diversification potential is small.

The paper analyzes the impact of the federal regulatory burden on poverty dynamics in Russia. The paper provides regional level indices of the federal regulatory burden on the economy in 2008—2018 which take into account sectoral structure of regions’ output and the level of regulatory rigidity of federal regulations governing certain types of economic activity. Estimates of empirical specifications of poverty theoretical model with the inclusion of macroeconomic and institutional factors shows that limiting the scope of the rulemaking activity of government bodies and weakening of new regulations rigidity contributes to a statistically significant reduction in the level of poverty in Russian regions. Cancellation of 10% of accumulated federal level requirements through the “regulatory guillotine” administrative reform may take out of poverty about 1.1—1.4 million people.
