Management key to reducing neosporosis

Management practices are your best defense against neosporosis, which is most commonly spread from an infected cow to her calf through the placenta.

New research confirms that management strategies are more important than genetic selection when it comes to reducing neosporosis, an abortion-causing infection caused by Neospora caninum.

According to an analysis of parentage data and blood-serum samples from 125 Ontario dairy herds, susceptibility to Neospora has a heritability of only 8.4 percent to 12.4 percent. That means you should focus your control efforts on management practices, like culling infected animals, rather than genetic selection.

The research appeared in the November Journal of Dairy Science.
