Abstract:Theobjectiveofthisstudywastoexaminetheeffectsofdifferentintensityof
bloodbiochemicalparametersofbroilers.
broilerswererandomlydividedinto4groups,20broilersforeach
group.Broilerswereheatstressedfor0h(asacontro1)andfor4h，byrapidlyincreasingtheambienttemperaturefrom(25±1)℃to（33±1）℃,（37±1）℃and（41±1）℃.ThepH,driploss,colorandshearforceofbroilerbreastmusclesineverygroupwereinvestigated.Clinicalbloodparameterwasusedtostudythebloodbiochemicalparametersofheatstressedbroilers.Theresultsshowedthat,incomparisonwiththecontrolgroup,thepH30min,pH24handa*valueofbroilerbreastmusclessignificantlydecreasedandthedriploss,L*andshearforcevalueclearlyimproved.TheactivityofCreatinekinase(CK),Lactatedehydrogenase(LDH)andMalondialdehyde(MDA)
