Leptospirosis in cattle
In a study carried out Eoin Lynch MVM it was found that 95% of all beef herds and 76% of all dairy herds have been exposed to leptospirosis infections and if an infection reaches an unvaccinated herd the effects can be severe. He advises that all herd owners should take action in the fight against this infection. Biotinmax 350g

How do herds become infected with Leptospirosis?
Leptospirosis is mainly spread through urine, this means all grazing cattle are in danger of becoming infected. The infection can spread where cattle drink from a natural water source such as a river running through land. Buying in unvaccinated cattle can bring the infection to your herd. The use of a stock bull can spread the infection. Sheep if co-grazing with cattle can spread the infection without showing any signs of infection themselves.
Vaccinating cattle can have increased conception rates.
Another study has shown that vaccinated cattle have a higher conception rate at first service. Herds were divided into two groups, one group was vaccinated and the other was not. The conception rate in vaccinated groups was 51% where the conception rate in the un-vaccinated group was 31%
