  1. 1. Äggstockscystor hos mjölkkor : en jämförelse av den kliniska bilden, förekomst, och diagnostiken idag mot för 10–20 år sedan

    University essay from SLU/Dept. of Clinical Sciences

    Author : Julia Nygårds; [2024]
    Keywords : follikelcysta; fruktsamhetstörning; fertilitet; riskfaktorer;

    Abstract : Äggstockscystor är en vanlig anledning till nedsatt fruktsamhet hos mjölkkor. Tillståndet uppstår till följd av en utebliven ägglossning där follikeln fortsätter att växa och blir kvarstående i äggstocken. Cystorna gör korna infertila under tiden som de finns kvar i äggstocken och kan därmed förlänga kalvningsintervallet. READ MORE
