Resumo: The resistence to nematode parasites in Corriedale sheep was studied to different types of hemoglobin (Hb). A group of 239 gimmers (24 with HbA, 103 with HbAB and 112 with HbB) were exposed to the same type of management and natural infection. Samples of feces were colleted on average every 28 days of Dec/90 to Nov/91 and were used for nematode egg counts per gram (EPG). The study revealed that the sheep with HbA presented smaller percentage of positive animals for EPG (P<0.05) in the months of Dec/90, Jun/91, Oct/91 and Nov/91 in relation to the sheep with HbB. The sheep with HbAB presented smaller percentage of positive animals for EPG (P<0.05) in the months of May/91 and Jun/91 in relation to the sheep with HbB. The hemoglobin type B sheep showed the highest mean values of EPG (P<0.05) in the months of Dec/90, May/91, Jun/91, Oct/91, and Nov/91. The results obtained in this study suggest that the sheep with HbB are the most susceptible to nematode parasites evaluated by fecal egg counts.

A resistência à verminose num rebanho ovino da raça Corriedale foi estudada em relação aos diferentes tipos de hemoglobina (Hb). Foram utilizados 239 borregas (24 com HbA, 103 com HbAB e 112 com HbB ), expostas às mesmas condições de manejo e infecção natural. Amostras de fezes foram coletadas a cada 28 dias, em média, de dez/90 a nov/91 e a contagem de ovos por grama de fezes (O.P.G.) revelou que os ovinos com HbA apresentaram menor percentagem de animais positivos para o O.P.G. (P<0,05) nos meses de dez/90, jun/91, out/91 e nov/91 em relação aos ovinos com HbB.Os ovinos com HbAB apresentaram menor percentagem de animais positivos para o O.P.G.(P<0,05) nos meses de maio/91 e jun/91 em relação aos ovinos com HbB. Com relação as médias de O.P.G. observou-se que os ovinos com HDB foram também os que apresentaram os maiores valores (P<0,05) nos meses de dez/90, maio/91, jun/91, out/91 e nov/91. Pelos resultados observados, os ovinos com HbB demonstraram a major percentagem de animais positivos para o O.P.G., assim como as maiores médias de O.P.G. ao longo do experimento. Os resultados sugerem que ovinos HbB são os mais suscetíveis à verminose Departamento de Diagnóstico e Pesquisa Agropecuária.
