Energy sources and requirements of the exercising horse.
This review outlines the energy sources available to the horse, from its diet and from its body stores, at rest and while exercising. It looks at the current ways of describing the energy potential of diets fed to horses and discusses the relative advantages and disadvantages of the digestible energy and net energy systems. The more empirical net energy system for calculating the energy availab...
متن کاملDigestibility and Metabolism in Icelandic Horses Fed Forage-only Diets
The objective of this thesis was to investigate digestibility and metabolism in Icelandic horses fed forage differing in stage of maturity/harvesting date and at two feeding levels. Additional aims were to compare digestibility and metabolic plasma profile in Icelandic and Standardbred horses. Finally, one aim was to estimate the digestible energy (DE) and digestible crude protein (DCP) require...
متن کاملGlycemic index of a meal fed before exercise alters substrate use and glucose flux in exercising horses.
In a randomized, balanced, crossover study each of six fit, adult horses ran on a treadmill at 50% of maximal rate of oxygen consumption for 60 min after being denied access to food for 18 h and then 1) fed corn (51.4 kJ/kg digestible energy), or 2) fed an isocaloric amount of alfalfa 2-3 h before exercise, or 3) not fed before exercise. Feeding corn, compared with fasting, resulted in higher p...
متن کاملEquine energetics. I. Relationship between body weight and energy requirements in horses.
Energy balance studies using indirect calorimetry were conducted with four mature equids ranging in weight from 125 to 856 kg. Each animal was fed three different levels of intake of the same diet. The amounts of digestible and metabolizable energy required for zero energy balance were determined by calculating regression equations for energy balance against energy intake. It was concluded that...
متن کاملEnergy uptake and utilization by limit- and ad libitum-fed growing horses.
Eighteen weanling horses were assigned to two treatments: limited or ad libitum feed intake. Growth and feed utilization were evaluated over a 78-wk period. Ad libitum-fed horses gained 24% more (P less than .05) weight than limit-fed horses. Total BW was distributed into 57% fore and 43% hind weight and did not differ between groups regardless of dietary treatment or age. Net gain and ADG in w...
