Realization of the genetic potential of laying hens makes it feasible to achieve the maximum possible yield of egg products against, while using effective feed compositions and various feed additives. Implementation of molecular genetic technologies for the analysis of intestinal microbiota and the expression of key genes for productivity and resistance is an important tool in studying mechanisms of the effects of feed preparations on microorganism of birds. Within the framework of the project for the development of modern biotechnologies to assess gene expression, we carried out an experiment to assess influence of human recombinant interferon alpha-2b on the expression of genes for productivity and immunity in laying hens. A positive effect of the additive on the immune system of birds and the effectiveness of molecular genetic technologies for assessing the expression of key genes and the use of the studied additives in feeding of egg-type poultry have been shown.

The white-throated sparrow (Zonotrichia albicollis) known for its morphological, behavioral and chromosomal polymorphisms represents a quite new model system to study genomic mechanisms underlying variable behavioral repertoire interwoven with population biology, reproduction and adaptation in this species. It was previously shown that these polymorphisms could be due to chromosomal rearrangements (inversions) on sparrow chromosome 2 (ZAL2) that is characterized by a heterogeneity in two distinct morphs, tan (ZAL2/ZAL2) and white (ZAL2/ZAL2m). To construct a comparative genomic map of ZAL2 and other chromosomes, we used a sparrow genomic BAC library, CHORI-264. Following a cross-species overgo hybridization approach, we screened the library and developed a first-generation BAC-based comparative physical map using the chicken and zebra finch reference genomes. The map includes 640 BAC-gene assignments for 77 loci and serves for further refining the genomic regions and identifying candidate genes that are affected by rearrangements and contribute to the observed behavioral polymorphisms. Mathematical assessment of the BAC-based hybridization data was undertaken to show evolutionary relationships of avian genomes.

Currently, special attention is paid to the optimization of the microbiota in the gastrointestinal tract (GIT) of highly productive commercial poultry. Many studies in the field of feeding, physiology, genetics, and resistance of poultry are devoted to this important area [1β4]. Various feed additives are studied and tested to help create and maintain optimal GIT microflora. Within the framework of a research project supported by the Government of the Russian Federation, biotechnologies are developed at the Skryabin MVA, including scientific approaches and practical techniques for managing the microbiota of the gastrointestinal tract, using modern methods such as assessing the expression of key genes using real-time PCR [5] and the composition of the gut microbiome based on T-RFLP analysis [6,7] and next generation sequencing. The developed technologies are successfully tested in the conditions of commercial egg production and adapted to the conditions of modern egg poultry farms in Russia. At the same time, the effects of feed additives are evaluated not only on the general state of the birdsβ organism, including the GIT microbiota [8β12], but also on the productivity and resistance of poultry to infectious diseases [13, 14]. In the future, it is planned to organically integrate the developed microbiota management technology into the existing technological programs for egg production, including that during prolonged exploitation of layers (after the peak of egglaying). At the same time, the synergistic interaction of microflora and various feed additives will be of great importance in order to achieve a favorable effect of additives on the intestinal microbiota and in order to maximize the genetic potential of modern egg laying crosses.

Skewness and kurtosis of mean transverse momentum fluctuations at the LHC energies
The first measurements of skewness and kurtosis of mean transverse momentum (β©pTβͺ) fluctuations are reported in PbβPb collisions at sNN = 5.02 TeV, XeβXe collisions at sNN = 5.44 TeV and pp collisions at s=5.02 TeV using the ALICE detector. The measurements are carried out as a function of system size β©dNch/dΞ·βͺ|Ξ·|<0.51/3, using charged particles with transverse momentum (pT) and pseudorapidity (Ξ·), in the range 0.2<pT<3.0 GeV/c and |Ξ·|<0.8, respectively. In PbβPb and XeβXe collisions, positive skewness is observed in the fluctuations of β©pTβͺ for all centralities, which is significantly larger than what would be expected in the scenario of independent particle emission. This positive skewness is considered a crucial consequence of the hydrodynamic evolution of the hot and dense nuclear matter created in heavy-ion collisions. Furthermore, similar observations of positive skewness for minimum bias pp collisions are also reported here. Kurtosis of β©pTβͺ fluctuations is found to be in good agreement with the kurtosis of Gaussian distribution, for most central PbβPb collisions. Hydrodynamic model calculations with MUSIC using Monte Carlo Glauber initial conditions are able to explain the measurements of both skewness and kurtosis qualitatively from semicentral to central collisions in PbβPb system. Color reconnection mechanism in PYTHIA8 model seems to play a pivotal role in capturing the qualitative behavior of the same measurements in pp collisions
