Tasty pork without odour or pain
Throughout the world most boars are castrated at an early age, often without anaesthetic or painkillers. Castration eliminates the unpleasant smell, known as 'boar taint' otherwise given off by pork from boars when cooked. But there are alternatives.
Breeding arctic char for aquaculture
A breeding programme for arctic char has resulted in a fish that grows three times faster than the 'original'. This is of great importance for the profitability of the burgeoning arctic char farming industry. Fish breeding research at SLU aims to improve fish characteristics that are central to economically and ethically sound fish farming. It is important that fish grow quickly, have good body shape,...
Fungi and mussels acceptable in fish feed
Farmed predatory fish (salmon, cod, etc.) need large quantities of food, which at present consists of wild-caught marine fish species that are endangered to varying degrees.
Spider’s silk for surgical sutures
Spider’s silk is an extremely strong and elastic biomaterial that can be used for many purposes: from surgical sutures to bullet-proof vests. Researchers at SLU have now learned how spiders produce their silk thread. Soluble proteins are produced from a gland in the spider’s body. When this solution passes through the thread canal, pH is lowered from 7 to 6, and the thread is formed. It is possible...
Traces of Chernobyl remain in reindeer
Several of the 51 reindeer herding districts in Sweden still have to adapt management to reduce the caesium content in reindeer. In total, this costs the Swedish society seven million Swedish crowns per year.
Mink warn of chemicals in the environment
SLU researchers have developed a new environmental monitoring system in which methods have been developed to reveal reproductive impairment in wild mink.
The Neighbourhood through the Eyes of your Child
What do children think about the outdoor environment in their neighbourhood? Researchers at the Swedish University of Agricultural Sciences (SLU) have developed a method using a Geographic Information System (GIS).
High Risk of Vole Fever in Northern Sweden
We are facing an outbreak of vole fever during winter, according to the annual forecast made by scientists at the Swedish University of Agricultural Sciences (SLU). This year’s high number of bank voles will spread the illness to a large number of humans.
Domestic Cat Reveals Hazardous Substances at Home
The domestic cat and its human owner share the same environment to a large extent. The cat can therefore serve as a model for the exposure and uptake of hazardous substances at home, especially applicable to small children.
Mixtures of substances disrupt hormone production
Hormone disrupting substances are present in the food we eat, in medicines, in pesticides and in pollutants. They may impair our reproductive capacity, our health, and our early development in the womb. Since we are exposed to a mixture of substances, it is difficult to determine their combined effect.
Land quest bad for African women
Increasing demand for food and fuel places considerable stress on land and water, especially for poor women in Africa.
Leptospira thrives in a humid climate
The disease leptospirosis is caused by the Leptospira bacterium, which is capable of infecting numerous kinds of animal, including dogs, horses, cattle, pigs and rodents.
Sesamine improves farmed fish
Farmed rainbow trout ( Oncorhynchus mykiss ) and salmon ( Salmo salar ) grow just as well when fed with food whose fat content comprises 75 per cent rape oil and only 25 per cent fish oil. Levels of the healthy marine omega-3 fatty acids DHA and EPA decrease in these fish, however. SLU researchers have now tested various bioactive substances from the plant kingdom and their ability to influence fish...
Plant defences resemble those of animals
New knowledge about immune systems may ultimately increase our chances of curing plant and animal diseases. SLU geneticists have collated knowledge on development of the defence in plants and animals.
Healthy fat from grazing heifers
We consume too much omega-6 fatty acids in relation to omega-3. In the modern diet the ratio between omega-6 och omega-3 is 10 – 20:1, although it would be better if the balance was 1 – 4:1 instead.
