Studying the Shape Variations of the Back, the Neck, and the Mandibular Angle of Horses Depending on Specific Feeding Postures Using Geometric Morphometrics (nih.gov)

“Our study showed evidence that different feeding positions are able to modify the shape of back and neck postures, as well as the magnitude of the mandibular angle […] Since hay nets are useful to increase the feeding time consumption, it is necessary to investigate all the postures that a horse may achieve when feeding out of a hay net and identify the height which allows a more natural overall posture.”

“In the present study, consistent improvements in welfare indicators were observed when horses ate roughage through the hay bag.”

Enclosed versus ring feeders: Effects of round-bale feeder type on horse behavior and welfare – ScienceDirect

“In this study, there was no indication that horses fed through the ring feeder had poor welfare as there was no difference in cortisol concentrations, aggressive behaviors, or feeding behaviors between treatments. However, horses fed using an enclosed bale feeder (Hayhut) displayed fewer agonistic threats, less avoidance behavior, and increased time at this feeder type during a preference test. This could have positive implications on horse management and welfare, by reducing distress experienced by horses while eating and providing horses with a resource they prefer.”

“Hay-bags” and “Slow feeders”: Testing their impact on horse behaviour and welfare – ScienceDirect

«We found that horses increased their time feeding on hay in both the hay-bag and the slow-feeder treatments compared to the hay on the stall ground treatment. While the hay-bag distribution was associated with an increase of frustration behaviours, the slow-feeder reduced “undesirable” behaviours, such as stereotypic behaviours, and increased “friendliness” towards humans. These results emphasize the importance of identifying feeding strategies and/or devices that improve feeding distribution and improve horse welfare.”

“In summary, despite a lack of difference in the time spent eating, horses consumed 20% less hay from the hay grid feeder compared with that eaten from the ground. The hay grid feeder used in this study may represent an alternative for the weight loss management of stabled horses.”
