“…Comparisons of H E and PIC of Curraleiro Pé-Duro breed in relation to other breeds that were studied using some microsatellite loci in common with this study showed similar findings in Creole (Steigleder et al, 2004) and Grey (Teneva et al, 2005) breeds. An exception was found for the TGLA122 locus, which showed a higher PIC in Curraleiro Pé-Duro.…”

Genetic characterization of Curraleiro Pé-Duro bovine breed from a conservation herd of Brazilian semiarid

et al. 2014

ABSTRACT. Curraleiro Pé-Duro is a rustic bovine taurine breed found in Northeast of Brazil; this breed has decreased its production potentially in order to adapt to the region environment conditions. Consequently, it is under risk of extinction and is maintained at a preservation center in Piauí State, Brazil, as a source of genetic material adapted to local conditions. We analyzed genetic variability of this breed using microsatellite markers. Sixty animals were genotyped using 11 microsatellite loci normally used for paternity tests in bovines. The observed number of alleles ranged from 5 to 9, and the effective number of alleles ranged from 2.01 to 4.64. The Shannon index ranged from 0.949 to 1.669. The expected heterozygosity ranged from 0.510 to 0.798. Polymorphism information content values ranged from 0.453 to 0.751. Divergence from Hardy-Weinberg equilibrium was significant and the mean F IS value was 0.010. We conclude that this breed still has some genetic diversity, but with evident risk due to genetic drift caused by current breeding management. It will be necessary to insert animals from other herds to obtain the desired level of genetic variability in this breed remnant.

“…For example, in a study of 35 Bulgarian Grey cattle the same loci were involved and 83 alleles were determined in total with an average 7.6 alleles per locus. The large number of alleles were determined at loci TGLA227 and TGLA53 (12 alleles), and lowest number at locus BM1824 (4 alleles) with equally high polymorphism detected at loci ETH3, BM2113 and ETH225, [18]. A similar study in Romania determined 125 different alleles in 5 different cattle breeds.…”

Molecular Characterization Of Autochtonus Slavonian Syrmian Podolian Cattle

et al. 2015

The aim of the study is to increase the knowledge on the genetic structure status of the autochthonous Slavonian Syrmian Podolian cattle breed currently listed by the FAO as "critically endangered". Blood samples obtained from a total of 20 randomly selected individua were included in genotyping upon microsatellite panel recommended by ISAG and FAO. The procedure enabled the identifi cation of as many as 214 (96.34%) genotypes and, at the same time, 129 allelic variations were found with X = 11.73 alleles per locus. The genotypes showed differences between the microsatellite loci and also signifi cant differences (p<0.05) in the frequency of both homozygosity and heterozygosity. The analyses of the allelic distribution within microsatellite loci showed marked variability. The distribution of genetic relationship was expressed by Wright's F coeffi cients. A moderate level of genetic diversity was observed at the tested loci. The fi ndings demonstrate the degree of breed relationship and breed purity but also indicate that gene pool of the tested population has been threatened. Therefore, urgent measures must be taken to support both the genetic consolidation and preservation of the remaining population of Slavonian Syrmian Podolian cattle in Croatia.

“…The Genomic DNA extraction from whole blood, PCR amplifications and Genotyping were performed in multiplex reactions by methods, described in previous study (Teneva et al, 2005). Eleven microsatellite loci recommended by ISAG /International Society of Animal Genetic/ for diversity studies in cattle -ETH225, INRA023, ETH10, ETH3, BM2113, BM1824, TGLA227, TGLA126, TGLA122, TGLA53, SPS115 were subjected to analysis.…”

Molecular characterization of bulgarian livestock genetic resources, II: Microsatelite variation within and among Bulgarian cattle breeds

et al. 2007

View full text Add to dashboard Cite

This study was undertaken to determine the genetic structure and the diversity among 2 local cattle breeds from Bulgaria, the Rhodope Shorthorn and Grey cattle. A panel of 11 microsatellites was used for the evaluation. For these loci, allele frequencies, heterozygosity, HWE, genetic disequilibrium, genic differentiation were determined. Both populations displayed a relatively high level of genetic variation as estimated by allelic diversity and heterozygosity. Heterozygosities ranged from 0.5424 /SPS 115/ to 0.8983 /TGLA 227/ for the Rhodope population and 0.6333 /TGLA 53/ to 0.9333 /TGLA227/ for Grey cattle, with similar average values for the two groups -0.7858 and 0.7757. These results clearly suggest that these breeds are suitable to preserve as a genetic resources.
