In Calabria region (southern Italy) goat farming is very widespread. Inside the several firms, autochthonous races, such the Nicastrese goats, are bred in a wild state. They represent an important economic resource for the agro-food sector. The aim of this research is to evaluate the possible correlation between haematological profile and parasitic state in Nicastrese goats. For this purpose individual samples of faeces and blood were collected. We examined 192 pluripara Nicastrese goats in good general health status, homogeneous for age (3.5 years +/- 0,6), body weigh (45 Kg +/- 1.7), physiological condition (between the 5th and the 6th week of lactation), and grazing season. We used FLOTAC double technique for parasitological diagnosis and ADVIA 2120 hematology analyzer for examinations of blood. All goats (100%) were naturally parasite by gastrointestinal strongyles. We grouped retrospectively the goats in quartiles according to gastrointestinal strongyles expressed in eggs per gram of faeces. In addition, we performed haematological profile of individual blood sample. Haematological parameters were analysed by GLM procedure (general linear model) including gastrointestinal strongyles richness group as fixed effect (Q(1), Q(2), Q(3), Q(4)) and goats as random variables within group (n=50 for Q(1), n=47 for Q(2), n= 47 for Q(3), n= 48 for Q(4)). Comparing the data carefully we didn't observe a significant modification of haematological parameters depending on the increase of mean parasitic intensity in quartiles. The results of this study allow us to assert that parasitological state of Nicastrese goat bred in a wild state, also if grave, has not influenced the state of haematological parameters in a significant way.
