Research by Ellis et al., (2015) looked at 4 haynets of varying sizes to establish the effect forage presentation had on intake behaviour. All smaller holed haynets (25-30 mm) were equally successful in slightly slowing feed intake down with an increased intake time of around 5 minutes/kg compared with the ‘large-holed’ haynet (75 mm). Night observations showed no difference in the time to finish eating between the haynets.

In- house testing of the Haygain Forager has shown a reduction in intake rate by 35% compared with the white regulator and 73% with the standard regulator when compared to a haynet. CCTV footage has shown horses eating into their ration into the early hours of the morning, with the added benefit of being able to eat in a natural feed position.
