Brazil is among the leading countries in meat production and exportation. The continuous growth of the national beef cattle industry relies on a sustainable and efficient production system. Thus, feed efficiency is a key player to address the costs of production and address the current challenges related to sustainability and use of natural resources. To understand the genetic architectur…
The increasing production of beef cattle and the exportation of meat in Brazil have positioned the country as one of the leaders in the global market. However, animal feeding remains a challenge due to the high costs for the national livestock industry. Thus, feed efficiency becomes strategic for the sustainability of the sector, as it can assist in mitigating methane emissions. To addres…
Brazil's beef cattle production sector is largely responsible for economic growth and makes the country the largest beef exporter globally. However, high productivity can have detrimental environmental impacts such as the emission of greenhouse gases (GHG). Fundamentally, the core goal for the country is to supply the world demand for animal protein without disregarding sustainability, fo…
The objective of this study was to evaluate phenotypic and genetic relationships between fertility traits and feed efficiency in male and female Nellore cattle. Data from 320 females born between 2004 and 2011 were used for phenotypic evaluation. These animals were evaluated for postweaning residual feed intake (RFI) and classified as negative (RFI < 0, mean = -0.294 ± 0.017 kg DM/d) or p…
In general, Brazilian beef herds need to improve their indexes of efficiency and the final product (meat) quality. Moreover, nowadays, there is a worldwide concern about the animal production sustainability, which could be improved selecting animals with decreased enteric methane emission to the atmosphere. With the evolution of the complete genome sequencing and the decreasing sequencing…
The Animal Science Institute (IZ), belonging to the São Paulo Agribusiness Technology Agency (APTA), from the São Paulo State Department of Agriculture and Supply (SAA), is responsible for developing and transferring technology and inputs for the sustainability of the systems of animal production. For the elaboration of the institutional Plan for Research Development of IZ (PDIP/IZ), the …

O trabalho da bolsista estará focado na etapa analítica e integrativa do projeto, envolvendo a exploração conjunta de dados fenotípicos,genômicos e metabolômicos para elucidar mecanismos associados à eficiência alimentar e à emissão de metano em bovinos Nelore. Asatividades incluem a realização de análises de regressão para identificar relações entre fenótipos e perfis metabólicos obtidos…
A Prova de Ganho de Peso (PGP) será conduzida no Instituto de Zootecnia, Centro Avançado de Pesquisa de Bovinos de Corte, em Sertãozinho/SP. O estudo terá como objetivo a avaliação do desempenho de machos inteiros da raça Nelore, considerando características fenotípicas associadas ao crescimento e eficiência alimentar. Os animais serão mantidos sob condições controladas, permitindo a anál…
The increasing demand for productive efficiency and sustainability in livestock production has intensified interest in understanding the factors affecting traits such as residual feed intake, enteric methane emissions, and nutrient digestibility in cattle. However, to date, the relationship between feed efficiency and methane emissions remains contradictory. This study aims to model causa…

The aim of this study will be to evaluate the genomic prediction ability of methane emission traits in the Nelore breed using different genomic prediction models, validation strategies and response variable. The database currently consists of 1,050 Nelore animals, from four different herds with phenotypic information for: methane emission (CH4; g/day), methane emission per kg of dry matte…
A estimativa da emissão de metano entérico (CH4 em g/dia) será obtida em machos inteiros da raça Nelore (n=400), no Instituto de Zootecnia, Centro Avançado de Pesquisa de Bovinos de Corte, Sertãozinho/SP, utilizando a metodologia do gás traçador SF6, como descrita por Deighton et al. (2014), em datas pré-definidas. Após a determinação da taxa de liberação de SF6 durante 21 dias em tubos d…
A emissão de metano entérico é um processo natural e intrínseco ao animal e representa perda energética. Nível de consumo do animal, comunidade microbiana, além do valor nutritivo e composição química dos alimentos, são fatores que contribuem para a variação individual da emissão de metano. Ações de mitigação provenientes da seleção de animais de melhor eficiência alimentar podem ser perm…

Recently, livestock sectors have been exploring methods to reduce methane (CH4) emissions. The genetic selection of animals that emit less CH4 is both cumulative and permanent, making it an effective strategy to lower emissions in the livestock sector. Genomic multi-trait models have demonstrated improved prediction accuracies of genetic values when correlated traits are used. Research ha…
Reproductive rate and calf survival are directly related with the profitability and long-term sustainability of the beef cattle industry. A better understanding of the genomic background of reproductive rate and calf survival is paramount for optimizing genetic selection for these traits. The primary objectives of this research project are to i) identify Transmission Ratio Distortion (TRD…
The feeding costs represent the largest investment in livestock production systems. Feed efficiency is directly linked to increased meat production per unit of feed. Additionally, efficient animals are associated with the sustainability of the livestock system since they reduce the demand for food, consequently decreasing the impact generated by enteric methane emissions. In this context,…
The high production and export of beef cattle in Brazil led to a growing number of animals confined in the national territory and allowed the country to rank in a prominent position in the world meat market. Nevertheless, the high cost of food represents the largest amount invested in the composition of diets in feedlots. Feed efficiency is directly related to increased meat production pe…
