| Summary: | 50 foot diameter roundpen, was as follows: each stallion was 8 after the initial day of exercise and by d 10 after the abnormal midpieces was observed for stallions 1, 2 and 3 by d an 8 wk forced exercise period (EP). Blood was collected confinement (stalls) with no exercise for an initial period cortisol, LH and testosterone concentrations. A significant decrease in the percentage of morphologically normal fitted with a heart rate (HR) monitor; walked for I min, Five breeding stallions, age 7 to I 1 years, were kept in for 30 min (electric horse walker) twice weekly (Sat., Sun.). for the percentage of progressively motile spermatozoa, total Fri.). Additional exercise was received when they were walked horse walker) three times per wk for 8 weeks (Mon., Wed., hourly for a 6 h period the day prior to and the day after initial day of exercise for stallions 4 and 5. min was observed and then for an additional 5 min at that HR, morphology, gel and get-free semen volume and total motility analyzer, semen concentration, spermatozoal of 60 days. A ten-day daily sperm output (DSO) determination Semen was collected for evaluation twice weekly during the 8 significant. Significant post-EP differences were observed spermatozoa and a significant increase in the percentage of spermatozoa number, Pre- and post-EP values for individual spermatozoa, gel-free semen volume and mean blood plasma spermatozoal motility with a computer assisted spermatozoal spermatozoal motility, percentage of morphologically normal stallions were compared and P < .05 was considered the end of the 8 wk EP. The exercise trial, performed in a the final 3 d of the two DSO determinations was analyzed for trotted for 2 min, exercised until a HR of 165-180 beats per trotted for a final 2 min; then walked for 30 min (electric was performed immediately before (pre-EP) and after (post-EP) wk EP on the 2 d with no exercise (Tue, Thur.).
