Miljøberikelse i form av ulike rotematerialer til avvente smågris : effekter på aktivitetsbudsjett
Pedersen, Signe Helen (Master thesis, 2019)Tidligere forsøk viser at rotematerialer fungerer godt som miljøberikelser på gris for å øke utforskende atferd, redusere frykt, aggresjon og stereotypiske atferder. Miljøberikelser kan defineres som en modifikasjon av ... -
Mjølfôr med høy norskandel for broilere sammenlignet med pelletert fôr og dens effekt på tilvekst

(Journal article; Peer reviewed, 2017)Behavioural assessments of shelter dogs (Canis lupus familiaris) typically comprise standardized test batteries conducted at one time point, but test batteries have shown inconsistent predictive validity. Longitudinal ... -
