The goal of this experiment was to detect if maternal care by ewes could be effective in mitigating psychological or physiological stress or pain in their offspring. We hypothesised that ewes are able to recognise when their offspring undergo an adverse experience and will adapt their maternal behaviour to buffer the effect of such events. […]
Sickness behaviours in ducks include anorexia but not lethargy
The characteristics of mammalian sickness behaviour are often conferred on the avian phyla despite there being little scientific evidence that birds change their behaviour when the innate immune system is activated during disease or infection. We used bio-logging techniques to measure activity and feed intake in birds exposed to different pathogen associated molecular patterns (PAMPs). […]
