The difficulty of maintaining adequate sanitary herd health conditions compromises the efficiency of goat breeding, especially in relation to parasite control. The goal with this study was to evaluate the sensibility of female Anglo-Nubiangoats to gastrointestinal nematodes. The does were evaluated stratified by physiological stage (lactating and non-lactating) in three age classes. The following characteristics were used: eggs per gram of feces (EPG), degree of anemia (according to the Famacha© method), weight and body condition score and percentage of fecal samples with EPG value equal to Zero, variable used to demonstrate the response to anthelmintic, available in the breed database at UFPI. Data is available for the period from January 2009 to December 2011. Lactating female goats had higher EPG mean value, higher degree of anemia, lower body condition score and fewer feces sampled with zero EPG value, when compared to non-lactating goats, regardless of the age group considered. Therefore, lactation increases sensitivity to endoparasitism in female Anglo-Nubian goats. Elevation of EPG tends to appear associated with an increased degree of anemia determined by the Famacha© method, leading to a reduction of body condition.
