| Summary: | (HR), respiration rate (RR), rectal temperature (RT) and (P>.05) amounts of feed. (P>.05) amounts of feed. On d 0, 7, 14, 21 and 28. Every 7 d a standardized exercise 14 and 28, and plasma linoleate concentrations increased on d 28 at rest and 30 min recovery when horses were fed F. 60:40 ratio. A digestion trial was conducted prior to d 7 the 'apparent digestibilities of energy, ether extract a given d were not different from values when the horses were and neutral detergent fiber in F were higher (P<.05) than and over recovery from the SET. Muscle biopsies were between treatments on any d. Pre-exercise data was normalized concentrations were higher (P<.05) when horses were fed F Consequently, d 28 pre-exercise muscle glycogen cutting horse training in a repeated switchback decreases (P<.Ol) in RR and RT over days, indicative of device to stimulate anaerobic metabolism. Heart rate difference in HR between treatments or days. There were easier heat dissipation due to decreased ambient Eight mature Quarter Horses were exercised by simulated experiment. Horses were fed a control (C) and a 10% fat- F, but values for glycogen utilization were not different fed C. There was no increase in muscle glycogen over time glycogen concentrations when horses were fed C than F. horses were fed F than C at all sampling times examined on d muscle glycogen storage from d 0 to d 28, however, values on obtained from the biceps femoris before and after each Plasma glucose concentrations on d 28 when horses were fed F Plasma oleate concentrations appeared to be higher when protein was higher (P<.05) for F than C. There was no seasonal changes. SET. Body weight and condition were maintained on similar supplemented (F) concentrate with bermudagrass hay in a temperature (P<.06) and humidity (P<.Ol) because of test (SET) was conducted utilizing a mechanical 'cow' than C. Plasma lactate concentrations did not differ between those in C. By d 14 apparent digestibility of crude to set d 0 values equal to zero, due to higher (P<.05) treatments, however, there was a decline (P<.05) by days. utilization increased (P<.05) from d 0 when horses were fed venous blood samples were taken prior to, during the SET were lower than when fed C at numerous sampling times. when horses were fed C. On d 7, 14 and 28, muscle glycogen When horses were fed F, there was an increase (P<.05) in |
