Brasília, DF: Embrapa Recursos Genéticos e Biotecnologia, 1999. 1 CD-ROM.c1999  aThe Morada Nova and Santa Inês are the two most important breeds of hair sheep raised in Brazil, found mainly in the Northeast and Central States and both are regarded as being highly resistant to the environmental conditions found in these regions. The Santa Inês is thought to have originated as a cross between the Morada Nova and other breeds and is still in formation as a breed. This study aims to compare these two breeds in terms of heat stress in conditions found in Central Brazil. There was no significant difference between the breeds for body weight. These results show that there is a need to further study the heat tolerance of these breeds in the Centre region of Brazil.  aBrazil  aEnvironment  aGoats  aHeart rate  aRaça Morada Nova  aRaça Santa Inês  aRectal temperature  aRespiration rate1 aMcMANUS, C.1 aCOUTO, F.
