Abstract Background Brazil holds the largest commercial cattle populations worldwide. Local breeds can be classified according to their origin, as exotic or Creole. Exotic imported in last 100 years, both zebuine and taurine, currently make up bulk of intensively managed populations. Locally adapted Creole breeds, originated from introduced by European conquerors derive natural selection events breed admixture. While historical knowledge exists on Brazilian very little is known genetic...
Santa Inês is the most common hair sheep breed in Brazil and probably has highest genetic diversity among breeds this country. Successful breeding programs for Brazilian are not various reasons, including a lack of control parentage flocks. We developed an allele frequency database 23 STR loci based on 285 animals sampled from five populations distributed across central-western north-eastern regions Brazil. The marker set included seven microsatellites used 2011 International Society Animal...
Abstract Western hemisphere goats have European, African and Central Asian origins, some local or rare breeds are reported to be adapted their environments economically important. By-in-large these genetic resources not been quantified. Using 50 K SNP genotypes of 244 animals from 12 goat populations in United States, Costa Rica, Brazil Argentina, we evaluated the diversity, population structure selective sweeps documenting migration “New World”. Our findings suggest concept breed,...
Genetic variability at 11 microsatellite markers was analyzed in five naturalized/local Brazilian horse breeds or genetic groups.Blood samples were collected from 328 animals of the Campeira (Santa Catarina State), Lavradeira (Roraima Pantaneira (Pantanal Mato-Grossense), Mangalarga Marchador (Minas Gerais as well group Baixadeiro (Maranhão and exotic English Thoroughbred Arab.We found significant within evaluated loci, with observed heterozygosis varying between 0.426 0.768 polymorphism...
The aim of this work was to investigate the possible origin local Brazilian pig breeds through Cytochrome b (MT-CYB) mitochondrial analyses. results indicated that main descended from two different European maternal lineages, both Iberian varieties. haplotype relationship analysis showed Monteiro, Nilo, Piau and Tatu share haplotypes only with varieties, while Moura breed presented a lineage. appears high frequency Black Hairy variety Hungarian Mangalica breed.
Uniquely selected breeds bred over thousands of years domestication in a wide range environments have been declared extinct the last century. Still more are at risk becoming and rate continues to accelerate. Assessing current status possible future dynamics livestock is therefore critical step management Animal Genetic Resources (AnGR). This study applies qualitative approach comprehensively analyze cattle genetic resources countries order better understand those that need be considered...
The objective of this study was to assess genetic diversity among 5 Brazilian (155 animals) and U.S. goat (120 breeds using 23 microsatellite markers. Samples from the United States represented a broad geographic distribution whereas samples were northeast region. Boer common each country's breed count. Expected observed heterozygosity ranged 0.55 0.72, suggesting ample in evaluated. Angora, Spanish, Nambi ranked highest for allelic richness, averaging 6.1, 7.1, 6.5 alleles per locus,...
Background: The lack of information on population structure is one the main obstacles to develop breeding and conservation programs for animal genetic resources. Objective: To characterize Crioula Lageana cattle breed (Bos taurus) in order assess its diversity. Methods: Database with 1,638 animals, collected during 38 years, was analysed using ENDOG v.4.4 program. Results: Effective size ranged from 72.53 complete generations 143.90 maximum generations. Inbreeding Average Relatedness...
O objetivo do presente estudo foi avaliar medidas morfométricas de bovinos da raça Crioula Lageana em diferentes idades, para estabelecer padrões variação dessas medidas, contribuindo a caracterização fenotípica raça. Foram coletadas corporais (comprimento corporal, altura cernelha, perímetro torácico, garupa, largura garupa e comprimento garupa) 346 animais oriundos três regiões Planalto Catarinense (Campos Curitibanos, Coxilha Rica Campos Caçador). As foram avaliadas relação à idade, sexo...
