Life cycle inventories for beef cattle in Brazil. This chapter presents information on the main resources and emissions considered in the life cycle inventory for beef cattle production in Brazil. The beef cattle industry in Brazil was responsible fo... ... Repositório: BDPA Ano de publicação: 2018
Changes in cattle herd composition and its implications on greenhouse gases emissions in Mato Grosso do Sul State between 2010 and 2014. Cattle ranching is a major agricultural activity in Central Brazil and it plays a major economic role in Mato Grosso do Sul State. In the last few years, local agricultural development has been influe... ... Repositório: BDPA Ano de publicação: 2016
Accuracy of genomic predictions in Bos indicus (Nellore) cattle. Background- Nellore cattle play an important role in beef production in tropical systems and there is great interest in determining if genomic selection can contribute to accelerate genetic improvemen... ...

Correlation between pathological findings and bacteriological culture on paratuberculous cattle. ABSTRACT - Paratuberculosis (PTB) is a chronic enteritis determined by Mycobacterium avium subsp. paratuberculosis (Map) that affects ruminants. Three crossbred dairy cattle with clinical PTB were nec... ... Repositório: BDPA Ano de publicação: 2008
Genotype imputation strategies for Portuguese Holstein cattle using different SNP panels. Although several studies have investigated the factors affecting imputation accuracy, most of these studies involved a large number of genotyped animals. Thus, results from these studies cannot be dir... ... Repositório: BDPA Ano de publicação: 2019
Genomic selection in multi-breed dairy cattle populations. Abstract Genomic selection has been a valuable tool for increasing the rate of genetic improvement in purebred dairy cattle populations. However, there also are many large populations of crossbred dai... ... Repositório: BDPA Ano de publicação: 2016
Characterization of a novel microdeletion polymorphism on BTA5 in cattle. We present a detailed breakpoint mapping and population frequency analysis of a 214-kb microdeletion that removes multiple olfactory receptor genes. Using progressive rounds of PCR assays, we mapped t... ... Repositório: BDPA Ano de publicação: 2008
The genetic ancestry of American Creole cattle inferred from uniparental and autosomal genetic markers. Cattle imported from the Iberian Peninsula spread throughout America in the early years of discovery and colonization to originate Creole breeds, which adapted to a wide diversity of environments and... ...
