Resumo: | Breeds of goat (Canindé, Anglo-Nubian, Bhuj) and of woolless sheep Morada Nova and Santa Inés were used in the tropical Northeast Brazil to compare their rectal temperatures and respiratory rates before and after exercise and thereafter upto one hour to evaluate tolerance to environmental heat. Results showed that initial body temperature was not different among the five breeds and after exercise it rose by 1.25°C to 1.95°C in breeds. There was no species difference in rise to body temperature. After exercise, most rapid recovery was made by Bhuj and Canindé goats. Recovery was slower in Anglo-Nubian and the two sheep breeds. Initial respiratory rate appeared to be high in Anglo-Nubian in comparison to other breeds of sheep and goats. After exercise, sheep breeds showed smaller rise in respiratory rate than goats. This may explain the faster rate of recovery of body temperature by Bhuj and Canindé which had distinctly higher post-exercise respiratory rates. The respiratory rate of Anglo-Nubian had returned to pre-exercise level within 15 minutes of termination of exercise and it was only in case of Bhuj that the respiratory rate continued to be high at 15 minutes after exercise. Thirty-minutes after exercise all breeds had returned to their normal pre-exercise rates of respiration. |

Resultados mostraram que a temperatura retal inicial não foi diferente entre as cinco raças; após exercício, elevou de 1,25°C até 1,95°C nas diferentes raças; não houve diferença da elevação da temperatura corporal entre espécies. Após exercício, a recuperação foi rápida nos caprinos Bhuj e Canindé. A recuperação foi mais lenta na Anglo-Nubiana e nos ovinos. A variação inicial no ritmo respiratório apresentou-se elevada na Anglo-Nubiana em comparação com as outras raças de caprinos e ovinos. Depois do exercício, os ovinos apresentaram menor elevação no ritmo respiratório do que os caprinos. Isto pode explicar o grau de recuperação mais rápida da temperatura corporal dos caprinos Bhuj e Canindé, os quais tiveram distintamente os mais elevados ritmos respiratórios após o exercício. O ritmo respiratório da Anglo-Nubiana voltou ao normal dentro de 15 minutos após o exercício; somente o da Bhuj continuou elevado após os 15 minutos de descanso. Todas as espécies voltaram ao ritmo respiratório normal, após os trinta minutos de descanso.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraArruda, Francisco de Assis V.Pant, Kant Prasad2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15490Pesquisa Agropecuaria Brasileira; v.19, n.3, mar. 1984; 379-385Pesquisa Agropecuária Brasileira; v.19, n.3, mar. 1984; 379-3851678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15490/9434info:eu-repo/semantics/openAccess2014-04-16T19:18:59Zoai:ojs.seer.sct.embrapa.br:article/15490Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:18:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
