Abstract

Organizations involved with gene editing may engage with the public to share information and address concerns about the technology. It is unclear, however, if the information shared aligns with what people want to know. We aimed to understand what members of the public want to know about gene editing in animals by soliciting their questions through an open-ended survey question and comparing them with questions posed in Frequently Asked Question (FAQ) webpages developed by gene editing stakeholder organizations. Participants (338 USA residents) asked the most questions about gene editing in general and animal welfare. In contrast, FAQ webpages focused on regulations. The questions survey participants asked demonstrate a range of knowledge and interests. The discrepancy between survey participant questions and the information provided in the FAQ webpages suggests that gene editing stakeholders might engage in more meaningful public engagement by soliciting actual questions from the public and opening up opportunities for real dialogue.

Abstract

Hunger remains a significant animal welfare concern as restricted feeding practices are common on farms. Studies to date have focused on negative effects on health and productivity but little research has addressed the feeling of hunger, mostly due to methodological difficulties to assess animals' subjective experiences. Here, we explored the use of a cognitive approach to disentangle motivational hunger (a normal state that is of limited welfare concern) from distressful hunger (a state associated with intense negative emotions). Cognitive performance in a foraging task is expected to follow an inverted U relationship with hunger levels, providing an opportunity to make inferences about different hunger states. We assessed the effect of milk restriction on calf cognition in two experiments using a modified hole-board test. Experiment 1 showed that reducing milk allowance from 12 l to 6 l d−1 impaired all measures of cognitive performance. Experiment 2 showed that the same type of feed restriction also disrupted calves’ capacity to re-learn. We conclude that hunger associated with reduced milk allowance can disrupt cognitive performance of dairy calves, a result consistent with the experience of distressful hunger.
