SIX:Salmonella are usually killed by exposure to the volatile fatty acids of fully functional normal rumens

1. Normal Dry Matter Intake

2. Normal VFA level

3. No Growth of Salmonella in rumen

1. Lowered Dry Matter Intake

2. Lowered VFA level

3. Increase in number of Salmonella in rumen

1. Don’t have regular access to feed

2. During transport

3. Parturition

4. Subclinical ketosis

5. Hypocalcemia

6. Sudden ration changes

7. Ration maladaptation

8. Inadequate bunk space and pen space

9. Mixing submissive heifers with dominant cows at parturition

ACTION: Maximize rumen function by maximizing

a consistent dry matter intake in periparturient and

early fresh cows
