The Project
Research objectives, methodology, and scientific approach for understanding the genetic diversity and local adaptation of the Catrina breed.
Research Objectives
The three main research objectives of this exploratory project are
Genetic Characterisation
Genetically characterise the Catrina cattle with a high-resolution platform for the identification of signatures of selection.
Microbiome Analysis
Characterise the Catrina cattle and Holstein Frisian cows' gastrointestinal microbiome under two types of diets: semi-natural pastures and typical regional diet (grass, silages, additives).
Methane Measurement
Measure methane emissions in vivo using non-invasive laser methane detector technology.
Research Workpackages
Six major workpackages structured across the 18-month project time
WP 2
Chemical characterisation of the different diets
WP 3
DNA extraction and molecular characterisation
WP 4
Measurement of methane emissions in vivo
WP 5
Data Analysis
Scientific Relevance
Pioneer research with national and international significance
Innovation in Portugal
A pioneering project in in vivo methane measurement, using native breeds as a model for gastrointestinal microbiome studies in comparison with high-production dairy breeds.
Conservation Impact
Plays a critical role in the conservation of the Catrina cattle by providing data for breeding programmes and identifying genetic variants of value to other breeds.
Sustainability
Helps explain how feed efficiency affects environmental impact, supporting more sustainable livestock production.
Industry Application
Provides insights enabling the development of innovative animal feeds that enhance the agri-food sector's competitiveness and reduce environmental impact.
Sustainable Development Goals
Contributing to the UN 2030 Agenda through responsible research
Zero Hunger
Contributing to sustainable food security by improving livestock productivity and efficiency. Research on native breeds helps develop resilient agricultural systems that can better support local food production.
Responsible Production and Consumption
Promoting sustainable food production by studying feed efficiency in native breeds. Identifying genetic variants that optimise resource use while maintaining productivity, contributing to more responsible agricultural practices.
Climate Action
Measuring and understanding methane emissions from cattle to develop strategies for reducing the carbon footprint of livestock production. Supporting the development of feeds that promote lower greenhouse gas emissions.
Life on Land
Preserving the genetic diversity of the Catrina cattle, an autochthonous breed adapted to local conditions. Supporting biodiversity conservation and sustainable management of agricultural ecosystems in the Azores.
The MAXBOV project contributes to the One Health approach by improving animal welfare, productive efficiency, and environmental sustainability. By studying native breeds adapted to local conditions, we help maintain ecosystems while improving farm profitability through sustainable practices.
