CRC Rumensin

Administer one CRC rumensin bolus 3 weeks prior to calving.

How does Rumensin CRC work?

The monensin includes in these boluses changes the bacteria in the rumen. These bacterias produce propionic acid and cows will use this acid and convert it into glucose (sugar). We will get less ketosis (low sugar) in the fresh cows and less problems related to ketosis. Find out more…

Vaccine against mastitis (J-vac or Enviracor)

You have to give 3 doses of this vaccine. The first one at dry off, another one 4-6 weeks after, and the last dose after calving. This vaccine will help you to prevent acute mastitis for 4 months after the last shot.

How does this vaccine work?

These vaccines contain E.coli parts. This bacteria is responsible for acute mastitis (watery milk, swelling, fever). These bacterial parts aren’t stimulating the immune system properly. With 3 shots, we stimulate the immune system enough to help the cow when the real bacteria will show up. Find out more…
