articles about manure in Articles

The overall risk of a PRRS outbreak is 12 times higher during the first 15 days after pumping manure than the rest of the year.

How do ambient temperatures below thermoneutrality affect pig performance and environmental efficiency?

Climate changes have forced governments around the world to enforce legislation to reduce the carbon footprint from all parts of society including pig production.

Controlled crude protein reduction and use of essential amino acids can improve feed efficiency, decrease water consumption, and reduce nitrogen excretion.

Including dried brewers' spent grains in the feed not only provides protein but can lessen the environmental impact of pig slurry.

The working collective units and processing methods at the European level have been inventoried by country and by process.

What can we do to face the challenges in the industry? Innovate, research, and bring science closer to the field.

The application of BATs to optimize the management of slurry inside the barns means increasing the frequency of emptying the pits to the outside storage.

Eight years ago, Granja Capdevila Torrent Ramaders started up its biogas production plant using co-digestion and is now an example of economic viability and sustainability.

This article describes different techniques that can be applied, in order of priority, to prevent NH₃ and CH₄ emissions.

In this first article on emissions, Xavier Flotats explains how the main greenhouse gases and ammonia are generated on our farms.

This article provides an example of the cost per ton of CO₂ saved by reducing direct greenhouse gas emissions through daily slurry removal and anaerobic digestion.

We went to visit Piggly, a sustainable farm from an environmental, production, animal welfare, and economic perspective.

Using solar energy to evaporate part of the water from the slurry can be of interest, avoiding volatization of ammonia. Solar drying can be combined with other strategies.

Removing nitrogen from slurry by transforming it into N₂ can be done biologically or by physical-chemical methods, the latter of which are in the experimental phase for slurry.

Although these strategies do not include anaerobic digestion in the combination of processes and therefore do not take advantage of its benefits, they do provide a higher organic matter content in the recovered effluents.
