Can Scientists Influence Donkey Welfare? Historical Perspective and a Contemporary View

Humans have greatly benefited from their relationship with donkeys. Different roles that donkeys play in high- and low-income countries are two sides of the same coin. Their draft power is indispensable in low-income countries, and by contrast, their milk in Europe is fetching a premium. New productive niches are controversially being explored, for example, donkey meat and skin (ejiao); both are considered premium products and have increased value of donkeys in many developing regions of the world. New advances in human medicine are starting to consider possibilities of donkey serum and heart valves. Scientists and channels that they use to spread their knowledge directly influence public interest and implementation of welfare practices in domestic species, indirectly affecting their survival. The study's aim was to trace historical registry of www.sciendirect.com directory from 1896 to 2018 to assess trends followed by articles dealing with donkeys. Publications with 22 themes and 114 publications (91 JCR indexed journals) from 56 countries were included. JCR impact index was scored to study influence of publications dealing with donkeys. Chi-square test tested six variables, randomly influenced by the rest. Cramer's V measured strength of association between variables. Statistically significant differences were observed between almost every combination of variables except for year and JCR impact, year and area/topic and country of the corresponding author, and area/topic of submission. JCR impact and journal influences the area of the articles that are published. As some countries are more specialized in certain themes concerning donkey-related sciences, they are more likely to publish.
