Resumo: Erythrocyte, total leukocyte and eosinophil counts, just before and 14 or 17 days after anthelmintic treatments given in two seasons, were determined in kid goats of five breeds. The erythrocyte counts were affected (P<0.005) by the goat breeds and by the anthelmintic treatments. Considering that the animals were kept in pasture contaminated by Haemonchus sp., it is presumed that goats with the lowest erythrocyte counts (Bhuj in rainy and Marota in dry season) were the most infected. Similarly, it is presumed that goats with the highest counts before treatments (Anglo-Nubian and Moxoto in rainy and dry, and Caninde in dry season) were the least infected. The Caninde were the only goats whose erythrocyte counts were not further increased by anthelmintic treatment in any season. Maximum eosinophil percentages were observed in Caninde and Anglo-Nubian goats before anthelmintic treatment in dry season. At this time, the eosinophil percentages were reduced by the treatment. Considering that eosinophilia follows inflammatory and immune reactions against helminth parasites, it is possible that high eosinophil percentages in Caninde and Anglo-Nubian breeds indicate a efficient defence system. Accumulation of more data is necessary to reach final conclusions.

As contagens de eritrócitos foram influenciadas (P<0,005) pela raça dos animais e pela vermifugação. Como os animais foram mantidos em pastagem contaminada por Haemonchus sp., acredita-se que aqueles com menor contagem de eritrócitos antes das medicações (Bhuj na época chuvosa e Marota na seca) foram os mais parasitados. Acredita-se também que as raças com maior contagem nessas oportunidades (Anglo-Nubiana e Moxotó nas épocas chuvosa e seca, e Canindé na seca) foram as menos parasitadas. Os Canindé foram os únicos cujos valores eritrocitários nunca aumentaram após as vermifugações. As percentagens de eosinófilos mais altas ocorreram nos Canindé e Anglo-Nubianos antes da vermifugação da seca. Nessa época, as percentagens de eosinófilos foram reduzidas pela medicação. Como a eosinofilia acompanha as reações inflamatórias e imunitárias aos helmintos, é possível que as altas percentagens de eosinófilos nos Canindé e Anglo-Nubianos representem um mecanismo de defesa mais eficiente nessas raças. Essas hipóteses serão testadas em trabalhos futuros.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCosta, Carlos Alberto FagondePant, Kant Prasad2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15440Pesquisa Agropecuaria Brasileira; v.18, n.10, out. 1983; 1127-1132Pesquisa Agropecuária Brasileira; v.18, n.10, out. 1983; 1127-11321678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15440/9358info:eu-repo/semantics/openAccess2014-04-16T18:43:04Zoai:ojs.seer.sct.embrapa.br:article/15440Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:43:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
