The aim of this study was to analyze whole-genome re-sequencing data focusing on SNVs and InDels identified in Gir, Girolando and Holstein cattle breeds related to RFI. Thus, genes showing SNVs/InDels in TF binding sites (5' UTR variants) were used to search for TF related to feed intake and to generate a gene-TF network for RFI across two purebred and one admixed dairy cattle breeds. Moreover, we were able to perform a comparative analysis accessing similarities and dissimilarities at the genomic level across these breeds. |

Abstract BACKGROUND: Runs of homozygosity (ROH) are continuous homozygous segments of the DNA sequence. They have been applied to quantify individual autozygosity and used as a potential inbreeding measure in livestock species. The aim of the present study was (i) to investigate genome-wide autozygosity to identify and characterize ROH patterns in Gyr dairy cattle genome; (ii) identify ROH islands for gene content and enrichment in segments shared by more than 50% of the samples, and (iii) compare estimates of molecular inbreeding calculated from ROH (FROH), genomic relationship matrix approach (FGRM) and based on the observed versus expected number of homozygous genotypes (FHOM), and from pedigree-based coefficient (FPED). RESULTS: ROH were identified in... |

Resumo: Em ambientes tropicais e subtropicais, a expressão de características produtivas em bovinos é dificultada pelos efeitos ambientais como o estresse térmico, agravado pelo aquecimento global. Regiões genômicas associadas à tolerância ao calor foram recentemente descritas e polimorfismos de nucleotídeos únicos (SNPs) relacionados a essa variação foram identificados. Uma mutação no gene do receptor de prolactina, no SNP 39136666 foi relacionada à presença de um tipo diferente de pelagem denominada ?slick hair? em animais da raça Carora e Caracu, que está associado com a maior tolerância ao calor. Foram genotipados neste trabalho, 61 animais da raça Cararu Caldeano, utilizando a técnica tetra-primers ARMSPCR. A frequência alélica e genotípica foi... |

The objective of this work was to determine whether the random regression model using linear splines (RRMLS) is suitable to estimate the genetic parameters for productive and reproductive traits of a multiple-breed dairy cattle population, as well as to investigate the effect of the genetic group of the progeny on the genetic merit of the sire. The multiple-trait model (MTM) and the RRMLS with one knot fitted for every genetic group were used to obtain the genetic parameters. Records of 1/2 Holstein + 1/2 Gyr (1/2HG), 5/8 Holstein + 3/8 Gyr (5/8HG), and 3/4 Holstein + 1/4 Gyr (3/4HG) crossbreed dams were considered. The RRMLS showed better fitting. The additive and residual variances estimated by the MTM and the RRMLS were similar. Heritability varied from... |

Abstract The Indubrasil breed was developed in the Brazilian region called Triângulo Mineiro as a result of a cross between zebu cattle. Initially, it was used as a terminal cross and currently it represents approximately 4.45% of all the Brazilian zebu cattle. Studies were conducted to estimate genetic parameters in the Indubrasil using pedigree information, however, until now, no study has been developed using large-scale genomic markers in this breed. Pedigree information are widely used to investigate population parameters; however, they can neglect some estimates when compared to the use of genomic markers. Therefore, the objective of this study was to investigate the population structure and the genetic diversity of Indubrasil cattle using a... |

The Girolando breed progeny test was established in 1997, as a result of the partnership between Girolando and Embrapa Dairy Cattle. In 2007, the Programa de Melhoramento Genético da Raça Girolando? PMGG (Genetic Improvement Program of the Girolando Breed) was implemented. Besides interacting with previously existing initiatives of the Girolando Breeders Association, such as the genealogical register service, the progeny test and the dairy control service, the PMGG launched the Linear Evaluation System (SLAG). The main objectives of the PMGG comprises identification of genetically superior individuals, the technically-oriented multiplication of genetics, the evaluation of economic traits and the promotion of sustainable dairy activities. The program have... |
