Накратко на български

Математически модели за храненето на млечните крави помагат за по-ефективното усвояване на азота в организма им. Това намалява вредните емисии на амоняк и азотен оксид, които замърсяват околната среда и засилват парниковия ефект.

Upgrading and implementing mathematical models to increase nitrogen use efficiency of lactating dairy cows.

CowficieNcy is an applied research project that aims to increase nitrogen use efficiency of dairy cattle, because this is the best strategy to reduce nitrogen pollution from dairy farms. Nitrogen emissions from cows contribute to the powerful greenhouse gas nitrous oxide and to ammonia, and reducing the emissions of both of these pollutants is a overall policy objective of European countries. The overall aim of our project is to use modern and sophisticated modelling tools to accelerate the nutrition management of the dairy herd leading to improved farmer profitability and nitrogen use efficiency. We focus on both replacement heifers, which represent a significant portion of nitrogen pollution at the farm level, and lactating cows, which are the principal unit of nitrogen pollution. Research Plan Our main overall objectives are to upgrade nutrition tools that will lead to increased nitrogen use efficiency of dairy farming, and to help dairy practitioners to implement them. We have selected two basic models to work with: (i) the Cornell Net Carbohydrate and Protein System (CNCPS), and the Cattle Nitrogen use Efficiency model (CNE). We have dedicated a project work package (WP) to train participants on current model use (WP2: Training). The main focus of our work is to apply these models at a farm base. This is planned within WP3 (Field Research), which will transfer knowledge to several farms and feed-consulting companies across participating countries. At the same time, academic and non-academic partners will collaborate to further improve these models in WP4 (Model Research). Once the upgraded models are developed, the final implementation will take place on selected dairy farms. Dissemination Plan Dissemination and communication of our research findings to the public is an integral part of CowficieNcy, and a specific work package is dedicated to it. A number of traditional and non-traditional tools are used to approach not only the scientific community but also any citizen concerned with environmental issues related to dairy farming.

Цел на проекта

Nitrogen (N) is an essential nutrient of food production, but its extended use led to the N cascade phenomenon with considerable effects on atmospheric, freshwater and marine systems. The increased efficiency of N use in dairy production is proposed as key action to reduce N contamination, and mathematical models provide a powerful tool to help with this. We are planning to use two models: The Cornell Net Carbohydrate and Protein System (CNCPS; a cow based model) and the Lifetime Nitrogen Efficiency (LNE; a herd based model). The models will be updated on amino acid metabolism (CNCPS), heifer growth and cattle fertility and economics (LNE) increasing not only their accuracy but also their commercial potential. In parallel, an intensive outreach program will incorporate farms in each country to describe N balance situation. This step will provide the necessary time to familiarize and accommodate farms with current model use. The last phase of the project consists on the implementation of the upgraded models in our pilot farms. This will provide a real life example that can generate a shift in agricultural practice towards more efficient and less polluting dairy industry. The European Union has been taken several initiatives either at a research level (e.g. FP-7 project RedNex) or at a legislative level (e.g. the National Emission Ceilings directive 2001/81/EC; currently under revision) to reduce N pollution from dairy production. However, few strategies have been converted into agricultural practice because of the lack of an applied step linking research strategies with the dairy industry. This is the strength of the current project that includes four non-academic partners that consult on thousands of European dairy farms and six European and American academic institutions, two of which developed the models, but all highly prestigious in their countries and internationally.
