Summary: | The objective of this study was to assess the applicability of temperament tests commonly used in bovines for water buffaloes (Bubalus bubalis). The tests for docility, reaction to a novel object, squeeze cage and social isolation were applied individually with 12 calves and their 12 mothers. Both calves and their mothers responded to all tests with a variety of behaviors. The tests that elicited the larger number of behaviors were the squeeze cage and the novel object. There were large individual differences (coefficients of variation of 32-51%) in the scores for all tests for calves and adults. The individual scores for the tests of isolation and novel object were significantly correlated for calves ([r.sub.s] = 0.66, P< 0.01) and adults ([r.sub.s] = 0.76, P< 0.01). Using the criteria of sensitivity (range of individual differences), responsiveness and applicability, the squeeze cage test and the isolation test seem well suited for water buffaloes. Key words: buffaloes, handling, animal production, Bubalus bubalis. O objetivo neste trabalho foi avaliar a aplicabilidade, para bufalos (Bubalus bubalis), de testes de avaliacao de temperamento, utilizados para bovinos. Foram avaliados os testes de docilidade, teste de reacao a objetos novos, de tronco e de isolamento social em 12 bezerros e suas 12 maes, separadamente. Tanto os bezerros como suas maes responderam a todos os testes com varios comportamentos. Para os bezerros e as maes, os testes que promoveram maior numero de comportamentos foram o de tronco e de reacao a objetos novos. Houve diferencas individuais (coeficiente de variacao de 32-51%) nos resultados de todos os testes tanto nos bezerros como nas maes. Os resultados individuais, em testes de isolamento social e de reacao a objetos novos apresentaram correlacao positiva tanto com as maes ([r.sub.s] = 0,76, P< 0,01) quanto com os bezerros ([r.sub.s] = 0,66, P< 0,01). Baseados em sensibilidade, relevancia e aplicabilidade, o teste de isolamento social e o teste de tronco podem ser sugeridos para avaliarem o temperamento de bubalinos.
