“…Furthermore, their identification of two groups in the data is based on the use of Structure Harvester, which cannot assess whether one group (cluster) in the data is the optimal partition solution. As shown in the Kaweçka et al [51] delta likelihood plot, a clustering solution with only one cluster is more likely than any of the other partitions suggested by the authors.…”

“…Our observed lack of population structure within Carpatina also reflected the results of the SNP array data by Colli et al [9], which shows that for the limited dataset they had (14 Carpatina individuals), the Admixture analyses did not render population structure within the breed. The only instance of some population structure reported for Carpatina is for Polish samples by Kaweçka et al [51], who analyzed 249 animals from 14 farms using microsatellites. In their study, they argued for the identification of two groups of animals with one group largely represented by animals from one farm.…”

Animal husbandry is one of man’s oldest occupations. It began with the domestication of animals and developed continuously, in parallel with the evolution of human society. The selection and improvement of goats in Romania was not a clearly defined objective until around 1980. In recent years, with the increasing economic value given to goats, breeding programs are becoming established. In Romania, a few goat genetic studies using microsatellites and mtDNA have been carried out; however, a systematic characterization of the country’s goat genomic resources remains missing. In this study, we analyzed the genetic variability of Carpatina goats from four distinct geographical areas (northern, north-eastern, eastern and southern Romania), using the Illumina OvineSNP60 (RefSeq ARS1) high-density chip for 67 goats. Heterozygosity values, inbreeding coefficients and effective population size across all autosomes were calculated for those populations that inhabit high- and low-altitude and high- and low-temperature environments. Diversity, as measured by expected heterozygosity (HE), ranged from 0.413 in the group from a low-temperature environment to 0.420 in the group from a high-temperature environment. Within studied groups, the HT (high temperature) goats were the only group with a positive but low average inbreeding coefficient value, which was 0.009. After quality control (QC) analysis, 46,965 SNPs remained for analysis (MAF < 0.01). LD was calculated for each chromosome separately. The Ne has been declining since the time of domestication, having recently reached 123, 125, 185 and 92 for the HA (high altitude), LA (low altitude), HT (high temperature) and LT (low temperature) group, respectively. Our study revealed a low impact of inbreeding in the Carpatina population, and the Ne trend also indicated a steep decline in the last hundred years. These results will contribute to the genetic improvement of the Carpatina breed.

The aim of this study was to analyse the milk parameters and the chemical, nutritional, and sensory characteristics of cheeses made from the milk of three groups of goats: native Carpathian goat, Anglonubian and crossbred goats (Saanen x Alpine). For this study, milk was collected three times during the grazing season and was processed into rennet semi-hard cheeses according to a traditional recipe in a pre-farm cheese dairy. Samples of the milk were subjected to physicochemical analyses. The chemical composition, vitamin, macronutrient content, and fatty acid profile of the cheeses were determined. The cheeses were also subjected to organoleptic evaluation. The results showed that the factors studied, such as breed and month of milking, had a significant effect on the physicochemical properties and chemical composition of goat milk. The month of milking affected all the milk characteristics studied, with September having the highest values of acidity, dry matter, fat and protein content. The month did not affect the level of basic components in the cheeses, but it influenced the content of vitamins and macronutrients; the cheeses produced in September had significantly higher levels of Mg, K, and vitamin E. The month of milking had, as did the breed of goat, a significant effect on the profile of most fatty acids in the cheeses. As for the breed factor, it affected both the chemical composition and sensory value of the cheeses. Cheeses made from the milk of the native Carpathian goat had the best health-promoting properties: a more favourable fatty acid profile, the lowest PUFA-6/3 ratio, and the lowest atherogenic index. According to the panellists, cheese from the milk of Carpathian goats also had the most distinctive aroma, typical for goat cheese. The research shows that the cheeses made from the milk of the native Carpathian goat had the best health-promoting properties, which confirms the need for further popularisation of the breed and can be the basis for marketing more products.

The aim of the study was to evaluate the differentiation among three goat breeds ? the autochthonous Carpathian goat and the cosmopolitan Alpine and Anglo-Nubian breeds – based on information from microsatellite markers. Blood samples of 64 goats were collected from three farms located in southern Poland. The population structure of the collected goats was investigated using the Bayesian approach, implemented in STRUCTURE 2.3.4. The Pairwise Population Fst analysis revealed that the largest genetic distinction was between the Anglo-Nubian and the Alpine breeds. In each of the analyses carried out, it was observed that the Carpathian breed is genetically more similar to the Alpine breed, while the Anglo-Nubian breed is a separate, much more distinct cluster. It therefore seems reasonable to carry out further research in the context of the genetic relationship between the two goat breeds (Carpathian and Alpine) adapted to the harsh conditions of mountainous areas.
