A survey on the feeding of eventing horses during competition


Brunner, Janine. A survey on the feeding of eventing horses during competition. 2012, University of Zurich, Vetsuisse Faculty.

Abstract

This study aims at the comparison of the actual feeding of horses with the recommendations from the literature, and it studies the effects of feeding and exercise on several blood metabolic parameters. Blood samples were collected from 25 horses during eventing competitions and evaluated for blood glucose, insulin, lactate, free fatty acids and triglyceride levels. Questionnaires on the feeding practices of the horses were evaluated. The questionnaires revealed that horses received on average 4.3 kg of concentrate per day (min. 1.54 kg, max. 8 kg). The statistical analysis showed no significant effect of the amount of concentrate fed before exercise on the measured blood values. Oil was supplied to 30% of the horses. Five horses (20%) had no access to salt supplements at all, and eleven horses (45%) had no access to salt on tournament days. During competition, 55% of the horses received roughage ad libitum, compared with 37% during training. The majority of the horses received less roughage on days before the cross-country competition. It could not be ascertained whether feeding a large amounts of roughage had a beneficial effect on performance, because only a few horses in this study were fed with very restrictive roughage. Feeding of most of the horses was in agreement with the recommendations from the literature, except the need for sodium and chloride. The salt need for sport horses may be overestimated in literature and needs to be re-evaluated.
