Cooperia spp. are another group of roundworm species found in cattle. They are a reddish colour and can reach
lengths of up to 10mm. Cooperia spp. have a direct lifecycle with no intermediate host. Female Cooperia worms lay very
high numbers of eggs and consequently can contribute heavily to pasture contamination, increasing the risk of disease in young cattle.
As a general rule Cooperia spp. are considered to be less pathogenic than Ostertagia but there is evidence to show
that heavily infected calves suffer poor weight gains and reduced appetite. Cattle that are co-infected with Cooperia
spp. and other worm species such as Ostertagia are morelikely to be affected by Parasitic Gastroenteritis (PGE).
As with other worms in young, non-immune cattle, Faecal Egg Counts (FECs) can give an indication of the number of worms in the gut, and provide a useful indicator of the need for treatment and the levels of pasture contamination.
Young cattle rapidly develop immunity to Cooperia spp. Parasite management plans put in place to control Ostertagia ostertagi in young cattle will be effective in managing the risk of PGE caused by Cooperia spp.
