Control of cryptosporidiosis in neonatal goat kids: efficacy of a product containing activated charcoal and wood vinegar liquid (Obionekk®) in field conditions.

Abstract

Many compounds have been screened for their potential anti-cryptosporidial activity in ruminants but none of them has been totally efficient in controlling the disease. A product containing activated charcoal and wood vinegar liquid demonstrated a good efficacy in controlling clinical signs and oocyst excretion in calves experimentally infected. This product (Obionekk(®), Obione, Charentay, France) was given to goat kids in field conditions. The product was administered in a preventive way at the dose rate of 3.75 g/day/kid of Obionekk(®) from the age of 3 days to the age of 17 days in suspension in milk replacer twice or three times a day. A significant reduction of oocyst excretion was observed when the product was given 3 times a day when compared to control group. The clinical signs (diarrhoea) were significantly reduced whatever the rhythm of distribution when compared to control group. These results demonstrated the efficacy of Obionekk(®) in preventing cryptosporidiosis in goat kids in field conditions.
