A bibliometric review on nutrition of the exercising horse from 1970 to 2010

Abstract

The main aims of the present review are to provide a bibliometric analysis of the research published on the nutrition of the exercising horse from 1970 to 2010 and to determine whether this research has had any practical impact on feeding practices. In addition, we evaluated whether some of the key nutritional questions posed at the beginning of the 1980s have in fact been answered. Less than 300 publications were published in the period 1970-1980, but a large increase in the number of publications was observed between the period 1981-1990 and the period 1991-2000. Most papers were published in the Equine Veterinary Journal and American researchers, universities or institutes were particularly productive. The majority of the publications were in the areas of fluid balance, fat and glucose metabolism. Using information from field studies, there appears to have been a trend for a reduction in the amount of starch rich concentrates fed to performance horses from 1979 to 2007 and an increase in the use of oil supplementation. Whilst there have been several significant advances in our scientific knowledge of nutritional practices over the past few decades that have become routine practice in the field, others have not cascaded down. Unfortunately, we have not really fully answered any of the questions posed in the early 1980s and whilst it is possible that such questions can never be fully answered, there is also a concern that lack of sufficient funding, especially for the fundamental pieces of information needed to underpin our nutrition advice, will hamper progress in the future.
