Genome association analysis for pregnancy status following parturition in cross...
Silveira, Juliano Coelho da; Passos, Daniel Thompsen; Glanzner, Werner Giehl; Aguiar, Paulo Ricardo Loss; Moraes, José Carlos FerrugemFoi avaliada a diversidade genética de nove marcadores moleculares, dos quais seis do tipo short tandem repeats - STR (BM4325, BMS3004, ILSTS002, IDVGA51, HEL5, AFZ1) e três do tipo single nucleotide polymorphisms - SNPs (LepSau3A1 A-B, LepSau3A1 1-2 e FSHRAlu1), ligados a genes envolvidos na reprodução e seus efeitos na performance reprodutiva. Foram examinadas amostras de sangue de 81 vacas sem raça definida,...

Association between reproductive traits and four microsatellites in Bragus-Ibag...
Oliveira, João Francisco Coelho de; Neves, Jairo Pereira; Amazonas, Erik de Almeida; Steigleder, Clara Sabina; Moraes, José Carlos FerrugemThe aim of the present study was to verify associations between reproductive efficiency and four microsatellite markers located in synteny with genes involved in the regulation of reproductive mechanisms. A sample of 107 females from a Brangus Ibagé population (5/8 Aberdeen Angus x 3/8 Nelore) was characterized for ETH225 (D9S1) and MM12E6 (D9S20) microsatellites, mapped on chromosome 9, and HEL5 (D21S15) and A...
Genetic polymorphisms at the leptin receptor gene in three beef cattle breeds
Almeida, Sabrina Esteves Matos; Santos, Luciana B. S.; Passos, Daniel Thompsen; Corbellini, Ângela Oliveira; Lopes, Beatriz M. T.; Kirst, CláudiaThe genetic diversity of a single nucleotide polymorphism (SNP) at the exon 20 (T945M) of the leptin receptor gene (LEPR) and of three short tandem repeats (STRs BM7225, BMS694, and BMS2145) linked to LEPR was investigated in three beef cattle herds (Brangus Ibagé, Charolais, and Aberdeen Angus). A cheap and effective new method to analyze the T945M polymorphism in cattle populations was developed and the possi...
Indução da ovulação em vacas de corte com diferentes ofertas forrageiras durant...
Terra, Gustavo Herter; Gonçalves, Paulo Bayard Dias; Oliveira, João Francisco Coelho de; Weimer, Tania de Azevedo; Neves, Jairo PereiraEste experimento teve por objetivo comparar a eficiência de um protocolo hormonal associado ao desmame por 96 horas com o desmame definitivo, em vacas em pastejo com diferentes ofertas forrageiras. Utilizaram-se 310 vacas (190 Aberdeen-Angus e 120 Charolês), entre 50 e 70 dias pós-parto, distribuídas em seis grupos. Os grupos A2, A5, B2 e B5 foram mantidos em maior (A2 e A5) e menor (B2 e B5) disponibilidade fo...
Association between molecular markers linked to the Leptin gene and weight gain...
Almeida, Sabrina Esteves Matos; Amazonas, Erik de Almeida; Terra, Gustavo Herter; Neves, Jairo Pereira; Gonçalves, Paulo Bayard DiasABSTRACT; Foram investigadas três repetições curtas em tandem (STRs), BMS1074, BM1500 e IDVGA-51 e três polimorfismos de um único nucleotídeo (SNPs) LEPSau3AI (A/B), LEPSau3AI (+/-) e LEPKpn2I, ligados ao gene da leptina, verificando-se associações com o desempenho produtivo em vacas no pós-parto, em dois rebanhos de gado de corte, Aberdeen Angus (AA, n=98) e Charolês (C, n=83). Após a reação em cadeia da polim...
Molecular diagnosis of Leptospira spp. in culled sows
Oliveira, Sérgio José de; Bortolanza, Fabrício; Passos, Daniel Thompsen; Pires-Neto, José Antonio Simões; Fallavena, Luiz Cesar BelloLeptospirosis diagnosis was performed through molecular, histopathological and serological tests in 30 culled sows in Rio Grande do Sul, Brazil. The objectives were to compare the efficiency of the three methods, to verify the sensitivity of a PCR methodology using a single primer based on the sequence of a repetitive element of Leptospira interrogans genome, as well as to verify the possible detection of Lepto...
