The Professional Animal Scientist (PAS) Update

Wayne Kellogg, Editor-in-Chief

The Professional Animal Scientist continues to improve visibility among scientists. We are receiving statistical information regarding readers and citations that was not available previously. Some of this information is provided from our publisher Elsevier. The journal is available to members of ARPAS (just enter the ARPAS site, log in, and click on the Professional Animal Scientist) on the HealthAdvance website (, and usage increased in the first half of 2017, compared to 2016. In 2016 the average number of monthly downloads was 989. For 2017, the average monthly downloads increased to 1,392. Via a separate website, we also observed an increase in usage by institutional users in 2017 compared with previous months. Earlier this year the papers with the most full-article downloads by institutional subscribers were the symposium paper “Transportation issues affecting cattle well-being and considerations for the future” and the research article “Management characteristics of beef cattle production in the Northern Plains and Midwest regions of the United States” (both from the December 2016 issue).
