“…A new locus never described before in chicken and related to pigmentation is the one mapped on GGA 1 around 100 Mb. Here, 3 genes are located, namely Chondrolectin ( CHODL ) , Transmembrane Serine Protease 15 ( TMPRSS15 ), and Neural Cell Adhesion Molecule 2 ( NCAM2 ) , which are involved in horn pigmentation in cattle ( Zsolnai et al, 2021 ). In detail, NCAM2 is implicated in the chondrogenesis in chicken embryo ( Fang and Hall, 1995 ), hence it could have a low P -value due to its involvement in general shank phenotype (like in cattle horn phenotype, according to Zsolnai et al, 2021 ), but not specifically in pigmentation of the shank.…”

“…One of the SNP associated with milk yield from chromosome 9 is ARS-BFGL-NGS-26381, nearest gene being ASF1A (anti-silencing function 1A histone chaperone). Whereas considered candidate gene for meat quality and body composition on chicken, Zsolnai et al (2021) reported association with birth and 205 days weight, with daily gain and maternal traits at Hungarian Grey cattle breed. This SNP seem to be highly connected with maternal abilities of the cows.…”

In Romania, the livestock is very scattered on the diverse environmental conditions. Due to difficulties regarding data collection, with the help of genomic selection, the paradigm of genetic improvement of economical traits in Romanian cattle breeds can be changed. Population studied in this paper consist in animals genotyped using 60k SNP panel. Association studies were performed for estimate the effect of SNP polymorphism on milk yield at 305 days. Genetic evaluation was compared under four statistical methodologies were compared under six scenarios 5k, 10k, 15k, 20k, 25k and 37k SNP panels. High association with phenotypes were displayed by 38 SNP’s. Generally, accuracy of the studied models, tend to increase with complexity (informational input). The model with the lowest accuracy was Sire-Model (36.6% accuracy). Adding information in Animal Model increase accuracy of estimation and finally, adding genomic information the accuracy was maximized to 69.9%. For each lactation all the statistical models return highly correlated breeding values. The highest (97.2%) and the lowest (79.2%) rank correlation are registered between Test-Day and Animal Model for the first and second lactation. Genomic evaluation is a more feasible methodology than classical breeding value estimation, in term of accuracy of selection and the quality of the parentage information.

“…Microsatellite markers are widely used in population genetics, conservation genetics, and parentage identification [ 16 – 19 ]. In recent years, several genetic analyses have been performed in cattle populations based on microsatellite markers [ 11 , 17 , 20 , 21 ]. Since no previous studies have been made concerning the genetic structure of Angus cattle in Hungary, we aimed to provide breeders with sufficient information to preserve and protect the genetic diversity of the breed and to indicate those herds, which demand special consideration by the HHAGA.…”

Objective: This study aims to investigate the genetic structure and characteristics of the Angus cattle population in Hungary. The survey was performed with the assistance of the Hungarian Hereford, Angus, Galloway Association (HHAGA).Methods: Genetic parameters of 1,369 animals from 16 Angus herds were analyzed using the genotyping results of 12 microsatellite markers with the aid of PowerMarker, Genalex, GDA-NT2021, and STRUCTURE software. Genotyping of DNA was performed using an automated genetic analyzer. Based on pairwise identity by state values of animals, the Python networkx 2.3 library was used for network analysis of the breed and to identify the central animals.Results: The observed numbers of alleles on the 12 loci under investigation ranged from 11 to 18. The average effective number of alleles was 3.201. The overall expected heterozygosity was 0.659 and the observed heterozygosity was 0.710. Four groups were detected among the 16 Angus herds. The breeders’ information validated the grouping results and facilitated the comparison of birth weight, age at first calving, number of calves born and productive lifespan data between the four groups, revealing significant differences. We identified the central animals/herd of the Angus population in Hungary. The match of our group descriptions with the phenotypic data provided by the breeders further underscores the value of cooperation between breeders and researchers.Conclusion: The observation that significant differences in the measured traits occurred among the identified groups paves the way to further enhancement of breeding efficiency. Our findings have the potential to aid the development of new breeding strategies and help breeders keep the Angus populations in Hungary under genetic supervision. Based on our results the efficient use of an upcoming genomic selection can, in some cases, significantly improve birth weight, age at first calving, number of calves born and the productive lifespan of animals.
