    Sammanfattning : Egg stocking is a common method of re-establishing brown trout (Salmo trutta) populations, while the outcomes have been shown to give different results depending on variations in methods and locations. More recently, the dispersal of yearlings has been studied, but research on intraspecific interactions after egg stocking and the optimal number of eggs stocked are less studied. LÄS MER

  3. 2. Den yngre respektive äldre hästens näringsbehov och omvårdnad för en god hälsa

    Sammanfattning : The horses nowadays are getting older and it is common that horses be fully active in competition in older ages. Loss of nutrients and weight loss in older horses is a common consequence when the horses have difficulties assimilating the feed. The dental health can affect the uptakes of nutrients. LÄS MER

  4. 3. The effect of temperature on productivity of birds in Sweden and Finland

    Kandidat-uppsats, Linköpings universitet/Biologi

    Sammanfattning : In the latest edition of NRC (2007) the feeding recommendations for Ca and P to growing horses were increased with 35 and 25 %, respectively, based on results from a Canadian study showing that daily endogenous fecal losses of Ca and P were greater than previously suggested. A Ca absorption efficiency of 50 % is used for all horses. LÄS MER

  7. 5. Determinants of winter kill rates of wolves in Scandinavia

    Sammanfattning : Winter wolf (Canis lupus) kill rates on moose (Alces alces) on the Scandinavian Peninsula are high and subject to strong variation, compared to other boreal wolf-moose systems. A more detailed understanding of factors influencing this variation is crucial for management and conservation of the Scandinavian wolf population. LÄS MER
