effekter på beteende och emission av kväve (NH3 och N2O)
… allowed. Therefore, a higher level of crude protein is needed in the diet to pigs, which lead to more nitrogen (N) excreted in the faeces and urine. N can be emitted to the air in the form of e.g. ammonia (NH3), which contributes to eutrophication and acidification and as …

… produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make …

… (ANS) that cause problems like growth depression for growing- and finishing pigs, and therefore limit their use as animal feed. The most common ANS in those crops are glucosinolates, tannins, proteasinhibitors, alkaloids, lectins, saponins, vicin and convicin. Other protein rich …
evaluation of methods, microbial activity and agronomic implications
… activity (PDA) was measured at fertilizer addition were performed. As controls pig slurry (PS) was used in both experiments along with a mixture of ammonium and glucose in the respiration experiment. In two follow up experiments soil PDA at addition of trace elements, extra …

… authority on a minimal amount of straw for conventional growing-finishing pigs, a study using 168 pigs provided 7 different amounts of straw (20, 40, 60, 80, 100, 200 or 300 grams/pig/day) was performed. The straw was provided either once or four times per day. Detailed …
associations with sow productivity and behaviour
… i.e. when an offspring nurses a female other than their own mother, occurs in pig production systems where sows are group housed during lactation. As production systems where several sows and their litters are housed together during lactation are getting more common, the need of …
Uganda är ett utvecklingsland i östra Afrika. Landet har närmare 36 miljoner invånare och populationen är den fjärde snabbaste växande i världen. Det är ett underutvecklat land som är hårt drabbat av fattigdom och HIV/AIDS. Jordbrukssektorn är en av landets viktigaste …
… to the Culex species. The main reservoirs are considered to be birds and pigs, with pigs constituting the most important reservoir in regard to human infection. During the last few decades the production of pork has increased significantly in Vietnam. With 90% of pigs being kept …
The guinea pig is an important meat-producing animal in Peru as well as in several other South American countries. They are held in different kinds of systems, from the small backyard breeders with few animals to the large commercial farms with thousands of guinea pigs. One of …
Piglet survival is a problem of great significance in pig production, affecting both animal welfare and economic aspects negatively. In Sweden it is illegal to use farrowing crates for sows on regular basis. To encounter this problem there is a proposal of an animal welfare …
… artiklar (20 stycken), men information hämtades även från Svenska Pig. I genomsnitt skilde sig kullstorleken inte mellan de olika produktionssystemen, men fler smågrisar gick förlorade hos suggor utomhus. Detta gav upphov till ett lägre antal avvanda smågrisar och en försämrad …
At the farm Fride, in Lojsta at the Southern part of Gotland, my family runs a pig production with 80 part-integrated sows in a ”Familybox-system”. The main parts of the facilities are from the early 90´s and have done their job. The production results have the last years …
