Feed concentrate palatability in welsh ponies: Acceptance and preference of flavors

Résumé

In horses, it is well established that nutrients and the palatability of feed material (odor and taste) play an important role in diet selection. For example, high-fiber feed taste is not well accepted by horses. Consequently, manufacturers have begun to supplement horse feed with flavors to mask feed bitterness, to overcome feed neophobia and to encourage water drinking. However, only few studies have been per -formed to evaluate the acceptance and preference of flavors in horses. The aim of this study was to evaluate the acceptance and preference of flavors supplemented on top of concentrate offered to ponies. Thirty-three female Welsh ponies aged between four to 13 years were enrolled in the experiment. Ponies were offered 4 flavored concentrates and one control with no flavor. The flavored concentrates were anise, caramel, raspberry and apple. The inclusion rate of the flavors was 300 g/t on an as-is basis. During the adaptation period (one week), the ponies were gently guided to each bucket containing the flavored con-centrate (200 g) during 10 sec/bucket for olfaction only. During the test period, ponies were allowed to freely choose flavored concentrates for 2 minutes. The flavors and the position of the buckets in front of the ponies were randomized. Each period was video-recorded and number of chews were counted during test period. The concentrate intake, eating time, and animal behavior were recorded during the test pe-riod. The apple concentrate was consumed the most at 116 g/2-min offering, whereas the raspberry and control concentrates were consumed the least, at 85.31 and 90.80 g/2-min offering, respectively. Apple flavor was preferred over caramel, raspberry and anise as indicated by higher consumption rate (g/sec) (chi-squared= 16.68, df = 4, P < 0.05). There was no effects on chews, smell or headshaking time per sec be-tween treatments. In conclusion, the ponies accepted a wide range of flavors with a preference for apple over raspberry flavored concentrate.
