Effects of dietary fatty acids on physiology and behaviour in guinea pigs

We are studying the effects of dietary saturated and unsaturated fatty acids in social-living guinea pigs, focusing on physiological and behavioural influences during different ontogenetic periods. The fatty acid composition of neuronal cell membranes is strongly dependent on the dietary fat intake and affects developmental processes and brain-related physiological and behavioural functions. As the social environment, including behavioural interactions and social stress, also represents a critical factor for developmental processes, we are primarily interested in how far these nutrients affect individuals in their social groups. Influences of different dietary fatty acids on social behaviour, spatial learning and memory abilities, reproduction, juvenile development, and physiological stress responses are currently investigated in relation to the animal’s social system and hierarchical structures. Further aspects address possible sex-specific, age-related, and cross-generational effects of these nutrients.
