“…For instance, polymorphism by C-2402T was determined for native Vietnamese chicken breeds, while the frequency of allele T was prevalent in the experimental populations (Vu et al, 2016). This fact was also observed in our studies (fi rst of all for dual-purpose Ukrainian chicken breeds) (Kulibaba et al, 2018). Promising mutations were found in the prolactin locus in different functional units of the gene in different breeds, the studies of associations with traits in which have been going on for rather a long time (Li et al, 2013;Osman et al, 2017).…”

Aim. To study the egg quality traits of Poltava Clay chicken line 14 and Rhode-Island Red chicken line 38 with different genotypes of the prolactin gene (PRL), growth hormone gene (GH), growth hormone receptor gene (GHR), insulin-like growth factor I gene (IGF-I) and Mx gene (Mx). Methods. The study was conducted using the method of polymerase chain reaction and restriction fragment length polymorphism analysis (PCR-RFLP). Results. We found signifi cant differences in line 14 for egg quality between prolactin, growth hormone, growth hormone receptor and Mx loci. Homozygous individuals CC and TT by prolactin locus prevailed over heterozygotes CT for egg weight on the 30th week of life. As for the growth hormone gene, the maximum differences for egg weight were revealed when comparing BC heterozygotes with CC homozygotes. As for the growth hormone receptor gene, signifi cant prevalence (p < 0.05) of individuals with the B0 genotype over A0 by parameters of egg yolk weight was noted at the age of 52 weeks. Signifi cant differences (p < 0.05) in eggshell thickness were determined for genotypes AG and GG by Mx gene in week 52. There were signifi cant differences (p < 0.05) in egg quality traits for prolactin and Mx gene for chickens of line 38. TT homozygotes by prolactin locus are characterized by the prevalence of values (p < 0.05) for the egg, yolk and shell weight. In case of Mx gene polymorphism, the heterozygous individuals were characterized by signifi cantly higher values (p < 0.05) of egg and albumen weight on the 30th week of life. There were no signifi cant differences in both experimental chicken lines for other egg quality traits between individuals with different genotypes. Conclusions. The data obtained are recommended for the use in breeding programs for Poltava Clay chicken line 14 and Rhode-Island Red chicken line 38 with the aim of obtaining microlines with the different genotypes for PRL, GH, GHR and Mx loci.

“…The studies on populations and lines of chickens of Ukrainian selection are rather scarce (Kulibaba et al, 2018). Unfortunately, these results are almost not used in national selective genetic programs that leads to gradual withering of the potential of domestic poultry breeding.…”

“…They can be classified as either MEB (if meat productivity qualities are the primary goals of selection; Bratishko et al, 2012;Bondarenko and Khvostyk, 2020) or EMB (if egg performance features are the primary targets of selection), despite the fact that their body weight and appearance hardly differ in any significant way (e.g. Khvostyk et al, 2017;Kulibaba et al, 2018Mueller et al, 2018Gal'pern et al, 2020;Larkina et al, 2021b).…”

In meat-type poultry breeding, pectoral angle (PA) is a conventional anatomical indicator for changes in body conformation and meat traits; its correlation to egg performance is however deemed controversial. In this context, we revisited, assessed and put forward evidence for the usefulness of this classic phenotypic variable and its specific integrative index of pectoral angle-to-body weight ratio (PA/BW). Specifically, we identified respective correlations and used them for distinguishing the major categories (production types) of diverse chicken breeds under the traditional classification model (TCM) and genotypic clustering models of the global chicken gene pool subdivision. Also, the usefulness of the supplementary integrative egg mass yield index (EMY) for this objective was demonstrated. Because of estimating the total mass of eggs laid (i.e. egg number times egg weight), EMY can serve as an indicator of egg production. Direct approximation of EMY values by PA and BW values did not lead to significant correlation dependences between these indicators in each of the four breed utility types according to TCM. However, using the ratio of PA to BW, instead of PA and BW alone, resulted in significant correlation of EMY with PA/BW, allowing for distinction between egg-type and non-productive breeds. The validity of the proposed correlation-based models was supported by PCA and Neighbor Joining clustering analyses. Collectively, we suggested that PA can be a potentially correlated trait for selecting hens and roosters in breeding flocks to boost egg yield. These results can also be applied to chicken breeding as well as conservation- and phenome-related research.

To improve the breed characters of farm animals, there is the need for breeding based on reliable information about the particular breed of animals, which is the key to high-quality breeding work. In this regard, there is a need to search for new methods of reliable identification of the breed of animals. The article presents an analysis of methods based on the achievements of modern genetics, which are used to obtain more accurate information when determining the breed of ani-mals. A brief description of methods for determining the species and breed identification of animals based on molecular DNA markers is given. Methods based on the study of polymorphism of mitochondrial DNA and microsatellites are analyzed. Spe-cial attention in this review is paid to the latest and most promising achievements in the field of high-performance genotyping technologies based on single nucleotide polymorphism (SNP). The analysis of the literature sources has shown that each breed of farm animals is characterized by its unique genetic structure, which should provide an objective result when deter-mining the breed of the animal.
