Parasitic gastro-enteric diseases represent one of the most critical management challenge in ovine flock, especially in organic breeding. The aim of this work is to point out the possible relationships between biochemical haematic parameters and parasitic nematode infection, as markers of a physiological disorder. A flock of 84 Massese sheeps was surveyed for 12 months, in order to achieve faecal (faecal egg count-FEC) and blood samples (non esterified fatty acids-NEFA, white blood cells-WBC, total protein-TP and triglycerides-TR). FEC was directly related with NEFA and WBC, while it was inversely correlated with TP and TR. Besides, hypoproteinaemia condition was associated with a level of 1720 egg per gram (EPG), whereas 1350 EPG seems to determine a pathologic high NEFA concentration. Taken together, these results prove that gastrointestinal nematode infection reflect in a significant variation in haematic parameters involved in energetic metabolism, important welfare-state indicators. This altered parameters in sheeps can be used as useful markers of sub-clinical nematode infection diseases, a frequent but often ignored ovine pathology.

Abstract
Parasitic gastro-enteric diseases represent one of the most critical management challenge in ovine flock, especially in organic breeding. The aim of this work is to point out the possible relationships between biochemical haematic parameters and parasitic nematode infection, as markers of a physiological disorder. A flock of 84 Massese sheeps was surveyed for 12 months, in order to achieve faecal (faecal egg count-FEC) and blood samples (non esterified fatty acids-NEFA, white blood cells-WBC, total protein-TP and triglycerides-TR). FEC was directly related with NEFA and WBC, while it was inversely correlated with TP and TR. Besides, hypoproteinaemia condition was associated with a level of 1720 egg per gram (EPG), whereas 1350 EPG seems to determine a pathologic high NEFA concentration. Taken together, these results prove that gastrointestinal nematode infection reflect in a significant variation in haematic parameters involved in energetic metabolism, important welfare-state indicators. This altered parameters in sheeps can be used as useful markers of sub-clinical nematode infection diseases, a frequent but often ignored ovine pathology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
