What is the advantage of a larger volume dosage?

Benzimidazole products, like Valbazen, work through direct contact with the parasite. With a large rumen/abomasum, a larger volume dose is more likely to expose parasites to the active ingredient and can help improve product efficacy. It is also important to give the product more time to work by slowing the rate of passage by the rumen through reduced feeding or fasting prior to administration.1, 2

Is timing of administration a factor in controlling liver flukes?

Timing is critical for use of Valbazen to control liver flukes because the product is only effective against the adult form (minimal efficacy against the larval stages). Much of the damage to an animal's liver occurs during the immature larval migrations. By controlling the life cycle location that can produce eggs (adults), we can effectively reduce pasture contamination (depending on weather conditions) and positively impact subsequent cattle generations. The timing of when adults appear varies based on available moisture and environment. Work with your veterinarian to determine the best time to administer.

Why should producers be concerned about protecting their cattle from parasites?

Parasites are found in all forage situations.

Internal parasites cause numerous problems:

  • Suppress appetite and reduce feed intake
  • Reduced nutritional intake through decreased ability to digest and absorb nutrients
  • Inhibit immune system to cause cattle to respond poorly to vaccines and disease challenges

Reduced nutrition intake impacts many aspects of animal performance including:

  • Gain
  • Feed efficiency
  • Immune response
  • Reproduction

Why invest in a brand name parasite control product?

  • Zoetis adheres to high standards in its manufacturing facilities.
  • Valbazen has stood the test of time with producers and veterinarians by effectively controlling internal parasites including liver flukes, tapeworms and Cooperia sp.
