“…Clustering patterns of breeds within three other models (PCM, GCM1 and GCM2) showed both similarities and dissimilarities as compared to TCM (Larkina et al, 2021a). Of the four above models, Vakhrameev et al (2022) chose the PCM variant, which, in our opinion, was optimal for such a subdivision of utility types among various chicken breeds. This was because PCM took into account a wide range of phenotypic (productive) traits: EN, egg weight (EW), BW and 13 morphometric parameters (including PA).…”

“…However, given the fact that it was not possible to answer unequivocally whether the assignment of breeds to a specific breed type within each model was carried out correctly (Larkina et al, 2021a), one can guess that previous results on the prospective use of PA and PA/BW (Vakhrameev et al, 2022) were only adequate for PCM. In this regard, we aimed here to evaluating the potential for using the PA trait and/or its specific integrative PA/BW index for the other subdivision models of the world chicken gene pool as reported by Larkina et al (2021a).…”

“…Due to investigations by Vakhrameev and Makarova (2021) and Vakhrameev et al (2022), PA has just recently come back under serious observation and examination as a single phenotypic variable. As described in more detail by Vakhrameev et al (2022), PA is considered a very important anatomical phenotypic indicator in the poultry industry. Its extreme values, from an obtuse angle, almost 180°, in final broiler crosses to an ultra-sharp one, i.e., 15-20°, are inherent in sick birds with an eloquent characteristic of 'rusks' or 'dried up' birds.…”

“…In our previous work (Vakhrameev et al, 2022), we suggested that PA, and especially its specific integrative index, i.e. the angle-to-body weight ratio (PA/BW), has a positive relationship with egg productivity, specifically, EN produced during the period of egg laying in egg-type breeds (ETB).…”

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.

A study for genomic variation that may reflect putative selective signaling and be associated with economically important traits is instrumental for obtaining information about demographic and selection history in domestic animal species and populations. A rich variety of the Russian chicken gene pool breeds warrants a further detailed study. Specifically, their genomic features can derive implications from their genome architecture and selective footprints for their subsequent breeding and practical efficient exploitation. In the present work, whole genome genotyping of 19 chicken breeds (20 populations with up to 71 samples each) was performed using the Chicken 50 K BeadChip DNA chip. The studied breed sample included six native Russian breeds of chickens developed in the 17th–19th centuries, as well as eight Russian chicken breeds, including the Russian White (RW), created in the 20th century on the basis of improving local chickens using breeds of foreign selection. Five specialized foreign breeds of chickens, including the White Leghorn (WL), were used along with other breeds representing the Russian gene pool. The characteristics of the genetic diversity and phylogenetic relationships of the native breeds of chickens were represented in comparison with foreign breeds. It was established that the studied native breeds demonstrate their own genetic structure that distinguishes them from foreign breeds, and from each other. For example, we previously made an assumption on what could cause the differences between two RW populations, RW1 and RW2. From the data obtained here, it was verified that WL was additionally crossed to RW2, unlike RW1. Thus, inherently, RW1 is a purer population of this improved Russian breed. A significant contribution of the gene pool of native breeds to the global genetic diversity of chickens was shown. In general, based on the results of a multilateral survey of this sample of breeds, it can be concluded that phylogenetic relationships based on their genetic structure and variability robustly reflect the known, previously postulated and newly discovered patterns of evolution of native chickens. The results herein presented will aid selection and breeding work using this gene pool.
