“…In fact, in terms of genetic variability, the endangered populations are less diverse, probably because of the reduced number of animals. The estimate of the molecular f coefficient was slightly greater than those reported by other authors for local cattle breeds and populations characterized by a reduction in their population sizes (Ginja et al, 2010;Maretto et al, 2012). Bozzi et al (2012), in a study for conservation of Tuscan cattle breeds using microsatellite markers, obtained a maximum value for the f coefficient of 0.48.…”

ABSTRACT:Genomic technologies, such as highthroughput genotyping based on SNP arrays, provided background information concerning genome structure in domestic animals. The aim of this work was to investigate the genetic structure, the genome-wide estimates of inbreeding, coancestry, effective population size (N e ), and the patterns of linkage disequilibrium (LD) in 2 economically important Sicilian local cattle breeds, Cinisara (CIN) and Modicana (MOD), using the Illumina Bovine SNP50K v2 BeadChip. To understand the genetic relationship and to place both Sicilian breeds in a global context, genotypes from 134 other domesticated bovid breeds were used. Principal component analysis showed that the Sicilian cattle breeds were closer to individuals of Bos taurus taurus from Eurasia and formed nonoverlapping clusters with other breeds. Between the Sicilian cattle breeds, MOD was the most differentiated, whereas the animals belonging to the CIN breed showed a lower value of assignment, the presence of substructure, and genetic links with the MOD breed. The average molecular inbreeding and coancestry coefficients were moderately high, and the current estimates of N e were low in both breeds. These values indicated a low genetic variability. Considering levels of LD between adjacent markers, the average r 2 in the MOD breed was comparable to those reported for others cattle breeds, whereas CIN showed a lower value. Therefore, these results support the need of more dense SNP arrays for a high-power association mapping and genomic selection efficiency, particularly for the CIN cattle breed. Controlling molecular inbreeding and coancestry would restrict inbreeding depression, the probability of losing beneficial rare alleles, and therefore the risk of extinction. The results generated from this study have important implications for the development of conservation and/or selection breeding programs in these 2 local cattle breeds.

“…Therefore, there are very few traces of the use of non-native bulls (Podolian or brachyceros type) in Istria, and occasional introductions were limited and conducted with a great care. This is supported by Maretto et al (2012), who observed a closer positioning of IC with respect to the geographically more distant southern Italian breeds (Maremmana and Podolica), than to the geographically closer beef type breeds (Chianina, Marchigiana, and Romagnola), suggesting a wellmanaged and tended ancient trade in animals across the Adriatic Sea. In the three autochthonous cattle populations, although the dominant haplogroup was T3 (84.25%), some of the observed haplotypes belonged to rarer haplogroups, T5 (11.64%) and T2 (2.05%).…”

“…In the population of IC, a considerable level of the maternal component variability has been preserved, as confirmed by the 13 observed mtDNA haplotypes. A high amount of conserved genetic variation in the population of IC was detected by Ramljak et al (2011) andMaretto et al (2012) using microsatellites, compared to a lower level in the BU population. The above claim is explained by IC having a more restricted breeding area, as well as by the centuries-old informal principles of breeding in Istria which favoured the local breed, very well adapted to the climate.…”

Genetic diversity and phylogenetic relationship of three Croatian autochthonous cattle breeds was analyzed using a sequence of the mtDNA D-loop region. Among Busha, Istrian, and Slavonian Syrmian Podolian cattle 146 unrelated animals were tested. The sequencing of 780 base pairs of the mtDNA D-loop region revealed 39 polymorphic sites representing 28 different haplotypes. The highest numbers of haplotypes were observed in the Busha population and the lowest in the population of Slavonian Syrmian Podolian cattle, while the highest level of sequence diversity within a population was observed in the Istrian cattle. Our results indicate a high level of mtDNA diversity in the populations of Busha and Istrian cattle and a low level of preserved diversity in the population of Slavonian Syrmian Podolian cattle. The sequence analysis showed substantial subdivision between the breeds (F ST = 0.1434), and a large fraction of variation within the breeds. Although the dominant haplotypes are classified as the T3 haplogroup, some of the haplotypes are classified as the rarer T2 and T5 haplogroups. Genetic information based on mtDNA typing has a great importance for the future conservation management and preservation of genetic diversity in autochthonous cattle breeds.
