Voluntary intake and digestibility in horses: individual variability in the effect of forage quality
In herbivores, the abundance, structure and quality of plant resources, which vary in time and space,are known to influence intake strongly.In ruminants,as quality of forages declines,digestibility and total intake decline.Equids are hind‐gut fermenters grazing herbivores, adapted to consume low quality forages.For many years it has been believed that the response of equids to a reduction in food quality is to increase intake to maintain rates of nutrient absorption (Janis,1976 ).All reviews of horse nutrition show that digestibility declines with forage quality ; for intake, however, most studies have found no significant relationship with forage quality, and more recently it has been suggested that horses may eat less in response to declining forage quality ( Dulphy et al., 1997 ).The aim of this meta‐analysis is to clarify the relationship between forage quality, digestibility and intake, allowing for the first time the differences between individual animals and diets to be controlled for.
