  1. 21. Boxtemperaturens effekt på antalet avvanda smågrisar : en fältstudie under svenska förhållanden

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Fay Wharton; [2021]
    Nyckelord :Gris; sugga; grisning; kullnummer; box; temperatur; avvanda smågrisar;

    Sammanfattning : Att maximera antalet avvanda smågrisar per sugga har blivit ett viktigt mål inom dagens svenska grisproduktion, men fortsatt stora problem med hög smågrisdödlighet utgör en utmaning för producenterna och har negativa konsekvenser för djurvälfärden. Temperatur är en miljöfaktor som kan inverka på smågrisdödligheten och som visat sig kunna variera mellan boxar i samma stall, men få studier har undersökt omgivningstemperaturens effekt på suggornas prestation under svenska produktionsförhållanden.
