| A presente investigação teve como objetivos: analisar animais presentes em diferentes criações de javalis no estado de São Paulo, com o intuito de auxiliar a identificação de javalis "puros" assim como javalis híbridos provenientes do cruzamento com o suíno doméstico, para tanto foram utilizadas avaliação do fenótipo dos animais, análises citogenéticas e da técnica molecular de RAPD (Random Amplified Polymorphic DNA).O estudo do número de cromossomos nas células diplóides em 104 animais destinados a análise citogenética e fenotípica, revelou polimorfismo de 2n=36, 37 e 38 cromossomos. Por meio da técnica de bandamento GTG foi possível identificação da translocação Robertsoniana entre os cromossomos 15 e 17 como responsável por esse polimorfismo. Todavia,... |

| O objetivo deste trabalho foi estimar os parâmetros genéticos e a tendência genética de características de crescimento e perímetro escrotal em animais da raça Brangus. Dados de 6.340 animais, criados em cinco propriedades nas regiões Sul, Sudeste e Centro‑Oeste do Brasil, foram utilizados para avaliação de: perímetro escrotal (PE) ao sobreano e pesos ao nascer (PN), à desmama (P205), ao ano (P365) e ao sobreano (P550). Os componentes de covariância foram estimados por inferência bayesiana, sob modelo animal, com efeitos fixos de grupos de contemporâneos e de classe de idade da vaca ao parto, e efeitos aleatórios genético aditivo direto e residual. Os efeitos aleatórios genético materno e de ambiente permanente materno foram incluídos somente para PN e... |

| The objective of this work was to evaluate the effects of single-nucleotide polymorphisms (SNPs) in the genes IGF1 (AF_017143.1:g.198C>T), MSTN (AF_320998.1:g.433C>A), MYOD1 (NC_007313:g.1274A>G) and MYF5 (NC_007303:g.1911A>G) on carcass and meat traits in Nelore (Bos indicus) and Nelore x B. taurus. A total of 300 animals were genotyped and phenotyped for rib eye area (REA), backfat thickness (BT), intramuscular fat (IF), shear force (SF) and myofibrillar fragmentation index (MFI). The effects of allele substitution for each SNP were estimated by regression of the evaluated phenotypes on the number of copies of a particular allele using the general linear model. The polymorphism at IGF1 was non-informative in Nelore animals. In crossbred... |

| Paternity misidentification is harmful due to the reduction in annual genetic earnings of the population and because it endangers an efficient genetic improvement program. The objectives of the present study was to evaluate nine microsatellites in Paternity Testing and to investigate misidentification paternity frequency in families of Gyr breed bovines population. In the present experiment blood samples from forty Gir breed families ( bull / cow / calf ), registered pure breed in the Zebu Breeders Brazilian Association (ABCZ) were used. The most part of the microsatellites used in this work were recommended by the International Society of Animal Genetics (ISAG). The genomic DNA extraction was performed from whole blood samples. The microsatellites... |

| Abstract: The objective of this work was to estimate allelic frequencies of the polymorphisms IGF2/MboII (G > T) of the insulin-like growth factor 2 (IGF2) gene, DQ499531.1:g.134A > T of the pro-melanin-concentrating hormone (PMCH) gene, and DQ667048.1:g.3290G > T of the RARrelated orphan receptor C (RORC) gene in beef cattle of different genetic groups, and to evaluate the associations between these polymorphisms and traits related to carcass composition and meat quality. Data on carcass and meat quality of 499 animals was used: of 313 Nellore (Bos indicus) and of 186 Nellore crossed with different taurine (Bos taurus) breeds. For the IGF2/MboII polymorphism, the frequencies found for the G allele were 0.231 and 0.631 for Nellore and crossed... |

| The objective of this work was to estimate the allelic and genotypic frequencies of CAST/XmnI, a calpastatin gene polymorphism, and CAPN530, a calpain 1 large subunit gene polymorphism, in different beef genetic groups (Nelore and Nelore x Bos taurus), and to investigate associations between these polymorphisms and carcass and meat traits. Three hundred animals - comprising 114 Nelore, 67 Angus x Nelore, 44 Rubia Gallega x Nelore, 41 Canchim, 19 Brangus three-way cross and 15 Braunvieh three-way cross- were genotyped by PCR-RFLP and phenotyped for rib-eye area (REA), back-fat thickness (BT), intramuscular fat (IF), shear force (SF) and myofibrillar fragmentation index (MFI). The occurrence of the two alleles of the CAST/XmnI and CAPN530 single nucleotide... |

| The objective of this work was to estimate the allele polymorphism frequencies of genes in Nellore cattle and associate them with meat quality and carcass traits. Six hundred males were genotyped for the following polymorphisms: DGAT1 (VNTR with 18 nucleotides at the promoter region); ANK1, a new polymorphism, identified and mapped here at the gene regulatory region NW_001494427.3; TCAP (AY428575.1:g.346G>A); and MYOG (NW_001501985:g.511G>C). In the association study, phenotype data of hot carcass weight, ribeye area, backfat thickness, percentage of intramuscular fat, shear force, myofibrillar fragmentation index, meat color (L*, a*, b*), and cooking losses were used. Allele B from the ANK1 gene was associated with greater redness (a*). Alleles 5R,... |
