  1. 1. Hur påverkas kotrafiken av blandfodrets sammansättning vid utfodring i automatiska mjölkningssystem?

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Maja Blom; [2018]
    Nyckelord :lata kor; kotrafik; blandfoder; mjölkningsrobot; fullfodermix;

    Sammanfattning : Studiens syfte var att undersöka hur sammansättningen av blandfoder påverkar den frivilliga kotrafiken (hur ofta korna frivilligt går till mjölkning) på gårdar med automatisk mjölkning (AM). Studien genomfördes på elva gårdar i Västra Götalands, Gävleborgs och Västernorrlands län där korna utfodrades med blandfoder på foderbordet totalt 939 kor. LÄS MER

  3. 2. Blandfoder eller separat utfodring till mjölkkor i AMS med fri kotrafik

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Hanna Driscoll; [2017]
    Nyckelord :foderintag; mjölkavkastning; mjölkningsfrekvens; automatisk mjölkning; grovfoderkonsumtion;

    Sammanfattning : The aim of the study was to compare two feeding strategies, partial mixed ration (PMR) and separate feeding (SR) of grass/clover silage and concentrate, and find out how feed intake, milking frequency and milk production was affected when the cows were milked in an automatic milking system (AMS) with free cow traffic. The study included 38 cows in early to mid lactation divided into two groups fed PMR or SR and lasted for ten weeks. LÄS MER

  4. 3. Nutrient efficiency in Swedish dairy cows fed total mixed rations or partial mixed rations

    Master-uppsats, SLU/Dept. of Agricultural Research for Northern Sweden

    Författare :Emelie Ferm; [2014]
    Nyckelord :feed efficiency; nitrogen efficiency; milk income over feed cost; total mixed ration; partial mixed ration; dairy cow;

    Sammanfattning : The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden.

  5. 4. Dried distiller’s grains with solubles and Swedish grown soya beans as protein feeds for dairy bull calves

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Animal Environment and Health

    Författare :Therese Fernqvist; [2011]
    Nyckelord :dried distiller s grains with solubles; soya bean; bull calves; protein feed;

    Sammanfattning : The cattle production in the world has been questioned in Sweden due to its negative impacts on the environment. The use of imported soya bean meal as a protein feed for Swedish cattle results in the cutting of rainforest and an extensive use of pesticides in the countries were the soya beans are produced.
