The Effect Of Supplemental With BCAA、Creatine On Athletic Performance And Blood Biochemical Index Of Racing Horse

This study aimed to determine the effects of supplemented with Branched-chain Amino Acid(BCAA), Creatine (Cr) on the sport horse’s athletic performance, and the change of the plasmaantioxidant index, hormone level, the concentration of creatine, glucose, lactic acid, uric acid andcreatinine after feeding4hours and before and after of1000m step speed competition withexperimental horses, for the BCAA and Cr provided in sports training, competition of horses andso on the application of sports to provide the reference data. The animals were chosen aged3-5years old (average4years old), weight390-514kg (average457±50kg), the similar performanceand will-trianed12YiLi horse stallion in1000m step speed competition. The sport horses wrerdivided into3groups,each group of4horses,one group fed with basal diet was used as the controlgroup to being compared, the experimentalⅠgroup was fed with diet supplementing with BCAAandⅡgroup was fed with diet supplementing with Cr, respectively. In the0d,1d,14d,21d,31djugular vein blood collected,and recorded the1000m step speed data. The results showedthat:Supplementing with Cr could obviously increase the competition results in the trotting race, itwas spent more less time compared with the control group in the second simulation game,it wasreduced by12.28%, but no significant difference(P﹥0.05). It was not obvious change in plasmaindicators after feeded Cr for4h. Supplementing with Cr increased plasma total antioxidantcapacity after the competition, extremely significant difference compared with the control group(P﹤0.01), two simulation game increased by35.91%and14.49%, respectively.It was nosignificant effect that the horse supplemented with BCAA, Cr in the other indexes.This studyresults showed that supplemented with BCAA, Cr all could increase the performance on the1000m step speed of horses,and supplemented with Cr have the most significant on the31d.Supplementation with BCAA, Cr increased plasma total antioxidant capacity after feede4h andafter30min of1000m step speed.
