CRINA® Ruminants

CRINA® Ruminants

CRINA® Ruminants is a unique, precisely formulated blend of essential oil compounds proven to have a positive effect on the rumen environment. By altering the balance of rumen microflora, CRINA® Ruminants helps improve rumen efficiency. CRINA® Ruminants has been shown to enhance milk production in dairy cows as well as live weight gain and feed efficiency in beef cattle.

Product Benefits

The proof

The benefits of feeding CRINA® Ruminants have been proven in trials at well-respected independent research centres around the world.

The payback

Improved weight gain together with better feed conversion rate means cattle finish sooner and feed costs are reduced. This will give better profitability and in addition, improved cash flow.

Feed Cost Saving

Adding CRINA® Ruminants to compound feeds delivers real benefits:

  • Allows potential reduction in the specification of feeds without affecting animal performance
  • Allows greater use of lower-priced ingredients, thereby reducing diet costs
  • Helps to reduce the impact of variations in raw material quality
  • Helps limit the effect of raw material price volatility on compound feed costs

CRINA® Ruminants provides a proven way of achieving greater control of formulation costs.

Applications & Uses

How Does Its Works
  • It reduces protein degradability from a broad range of dietary sources
  • It inhibits rumen bacteria that degrade amino acids to ammonia
  • It synchronises protein and energy metabolism in the rumen

Together they add up to better feed utilisation, increased production and higher profits.

Trial Results

During trials, CRINA® Ruminants has been shown to create a better balance of microbes in the digestive system, improving efficiency of digestion by:

  • Slowing the rate of starch fermentation
  • Reducing the extent to which protein is degraded
  • Preventing the growth of bacteria that turn valuable amino acids into waste ammonia

This has shown to improve the supply of nutrients available to animals, and translates into more milk from the same feed. It also has shown to generate greater feed efficiency, which improves cost savings on feed.

Providing Flexibility in Ration Design

The precise formulation of essential oil components in CRINA®Ruminants has been shown to improve rumen performance. As more of the protein provided can be used by the animal, it becomes possible to replace expensive protein sources with cheaper alternatives.

This is an effective way to achieve greater control over formulation costs and margins.
