Resumo: This experiment evaluated the parturition and lactating influence on the fecal nematode egg counts in female goats. The does were divided into four groups as follows: DND - dry nondewormed does; LND - lactating nondewormed does; DD - dry dewormed does; LD – lactating does, dewormed three to four weeks before parturition. The study was replicated in two parturition seasons. The egg per gram (EPG) counts and the fecal cultures were carried out weekly. In spite of the anthelmintic medication, the does who gave birth in October (middle of the dry season) presented higher EPG counts than the dry does. In the LND group, the EPG rises took place at the third and seventh weeks after parturition. During these peaks, the EPG counts in the LND group were higher (P<0.05) than the munts in the DND group. In the LD group, the EPG rises took place at the third week of the parturition period and from the third to sixth weeks after parturition. During these peaks, the EPG counts in the LD group were higher (P<0.05) than the counts in the DD group. The EPG rises in the does who gave birth in June (beginning of the dry season) were less defined. In the LD group, the EPG rises took place three and one weeks before the beginning of parturition. During these peaks, the EPG counts in the LD group were higher (P<0.05) than the counts in the DD group. The EPG rises observed in the lactating does were considered to be related to the development of inhibited larvae. Haemonchus was the most important nematode related to these rises.

Utilizaram-se quatro grupos de cabras, assim distribuídas: SNV secas não vermifugadas; LNV - lactantes não vermifugadas; SV - secas vermifugadas; LV - lactantes vermifugadas três a quatro semanas antes da parição. O estudo foi repetido em duas épocas de parição. As contagens de ovos por grama de fezes (OPG) e as coproculturas foram realizadas semanalmente. As cabras paridas em outubro (meados da estação seca) apresentaram maiores contagens de OPG que as cabras secas, independentemente da vermifugação. Os aumentos de OPG no grupo LNV ocorreram na terceira e na sétima semana pós-pano. Nesses aumentos, as contagens do grupo LNV foram superiores (P<0,05) às do grupo SNV. Os aumentos de OPG no grupo LV ocorreram na terceira semana do período de parição e da terceira à sexta semanas pós-parição. Nesses aumentos, as contagens do grupo LV foram superiores (P<0,05) às do grupo SV. Nas cabras paridas em junho (início da estação seca), os aumentos de OPG foram menos acentuados. Os aumentos de OPG no grupo LV ocorreram três e uma semanas antes do início da parição. Nesses aumentos, as contagens do grupo LV foram superiores (P<0,05) as do grupo SV. A maturação de larvas em hipobiose foi considerada a principal responsável pelos aumentos de OPG nas cabras lactantes. O Haemonchus foi o nematódeo que mais contribuiu para esses aumentos de OPG.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCosta, Carlos Alberto Fagonde2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15397Pesquisa Agropecuaria Brasileira; v.18, n.8, ago. 1983; 919-929Pesquisa Agropecuária Brasileira; v.18, n.8, ago. 1983; 919-9291678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15397/9287info:eu-repo/semantics/openAccess2014-04-16T19:06:19Zoai:ojs.seer.sct.embrapa.br:article/15397Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:06:19Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
