    The objective of this study was to collect and to quantify the ciliate genera present in the rumen, reticulum, omasum and abomasum in 30 slaughtered bovines. Rumen, reticulum, omasum and abomasum were sampled and their contents (45ml) were collected and evaluated for temperature, pH and ciliates population. The results showed that the rumen and reticulum environments are quite stable with average temperature between 36 and 37ÂșC and pH 6.5. The ciliate population in the rumen was Entodinium (65.0%), Isotricha (7.0%), Diplodinium (5.7%), Ostracodinium (5.1%), Eremoplastron (4.5%), Dasytricha (3.8%) and seven other genera which made 8.7%. In the reticulum, the population was Entodinium (35.2%), Isotricha (23.4%), Dasytricha (15.4%) Eodinium (7.2%), Eremoplastron (5.0%), Diplodinium (4.3%), Ostracodinium (3.8%) plus 5.6% of other five genera. The same genera were found in the omasum but in a smaller percentage than in the rumen and reticulum. No ciliates were found in the abomasum. The population profile analysis of the rumen samples has showed the predominance of type O (87%) followed by type B (13%).O presente trabalho teve como objetivo identificar e quantificar os gĂȘneros de ciliados do rĂșmen, retĂ­culo, omaso e abomaso de bovinos abatidos em matadouro municipal. Foram coletados 45ml de conteĂșdo de cada cavidade de 30 animais. No momento da coleta foram medidos temperatura e pH e as amostras posteriormente analisadas em laboratĂłrio. Os resultados mostraram que o ambiente do rĂșmen e do retĂ­culo Ă© bastante estĂĄvel com temperatura mĂ©dia entre 36 e 37ÂșC e pH 6,5. Os gĂȘneros mais encontrados no rĂșmen foram Entodinium (65,0%), Isotricha (7,0%), Diplodinium (5,7%), Ostracodinium (5,1%), Eremoplastron (4,5%), Dasytricha (3,8%) e outros sete gĂȘneros que totalizaram os 8,7% restantes. No retĂ­culo os resultados foram Entodinium (35,2%), Isotricha (23,4%), Dasytricha (15,4%) Eodinium (7,2%), Eremoplastron (5,0%), Diplodinium (4,3%), Ostracodinium (3,8%) e outros cinco gĂȘneros totalizando os 5,6% restantes. No omaso foram encontrados os mesmos gĂȘneros, porĂ©m em menor quantidade que no rĂșmen e retĂ­culo. No abomaso nĂŁo foram encontrados ciliados. A anĂĄlise do perfil populacional das amostras do rĂșmen mostrou predominĂąncia do tipo 0 (87%), seguido do tipo B (13%)
