Relationship between Neospora caninum Seropositivity and Udder Health in Lactating Dairy Cows
Keywords:Neospora caninum, economic losses, udder health parameter, somatic cell count
Neospora caninum is the most common infectious cause of abortion in Ontario dairy cattle. Most studies to assess the economic impact of N. caninum have identified losses associated with reproduction, milk production or culling. Few studies have investigated any potential influence of N. caninum serological status on udder health parameters. One European study reported an association between cows having moderate (200,000 to 400,000 cells/ml) somatic cell counts and N. caninum infection. The objective of this study was to determine if N. caninum serological status was associated with linear score or risk of elevated linear score in Ontario Holstein dairy cows.
