Livestock and animal manure


JTI develops and evaluates techniques and methods for functional, economical and environmental friendly animal husbandry. We work with systems solutions to achieve efficient management of animal manure and improved quality of milk and meat.

We strive for solutions that create a good environment for animals and humans alike. They also need to be sustained from an environmental point of view and cause minimal impact on land, air and water.

We work with agriculture's traditional livestock, but also with horses, which are widely used for recreational purposes nowadays.

Development to promote extensive agriculture

One trend in Swedish farming is currently towards more extensive animal husbandry. JTI is working out new techniques for keeping animals outside, techniques that allow production still to be kept firmly under control. Among other things, we have developed mobile pig huts with automatic feeding. In another project a new system is being studied for overwintering beef cattle on arable land. We are also developing techniques for improved animal keeping in stalls, like automatic securing and automatic straw handling.

Our researchers also develop and evaluate systems that provide more reliable monitoring and control of production. This may involve optical pig-weighing scales, a sensor that registers motion patterns or producing new in-trade guidelines for slaughtering. JTI deploys traditional measuring techniques, sometimes combined with sensors, for example to inspect the quality of milk in milk production or hygienic quality during the production of ensilage for fodder.

Animal manure - a resource to be utilized

Our developmental work takes place in close collaboration with the industry and farmers, and the systems and techniques we have evolved are tested in practice at actual farms. In the majority of projects we cooperate with other researcher groups and skills in order to achieve holistic solutions.

Environmentally friendly management of animal manure and other organic fertilizers involves utilization of the plant nutrients in crop production and minimize losses. JTI has developed methodologies for measuring both ammonia and the greenhouse gases methane and nitrous oxide.

JTI is working on a pilot scale to evaluate various covering materials for use in manure stores. In the field we are studying greenhouse gas emissions when manure is spread on the surface as compared with shallow injection it down into the soil. Here the spreading technique for shallow injection of slurry takes place in covered trenches in banks. The spreading technique has been developed at JTI and is being further developed in cooperation with a foundation stakeholder.
