CRINA® – delivering essential digestive performance

Our specific digestive solutions have been developed using specially-created blends of essential oil components.

Digestive efficiency has an immense impact on the performance and profitably of farmed animals. Animals that use feed more efficiently:

  • Grow faster
  • Produce more
  • Have lower feed costs
  • Are more profitable

Rising feed costs mean that the challenge of achieving more efficient digestion is even more important than before.

CRINA® contains essential oil components proven in trials to improve feed digestion and provide great benefits.

Essential oil components have shown to work on two fronts. Firstly, they improve the balance of gut microflora, increasing the proportion of beneficial bacteria and reducing the amounts of pathogenic and undesirable bacteria in the animal’s system.

Secondly, they have shown to stimulate the animal to produce more digestive enzymes. This improves the effectiveness of feed breakdown in the gut.

Of courses, different species require different essential oil components.

All flavoring components in CRINA® products are approved for feed and food, and appear on the Register of Feed Additives (Reg 1831/2003) of the European Union and the FEMA (Flavor and Extracts Manufacturers Association) and/or GRAS (Generally Recognised As Safe) listings.

CRINA® Poultry Plus

Ensuring a good gut feeling

Sometimes you can take two successful products and create something even better. That is exactly what we have done with CRINA® Poultry Plus, and now poultry producers stand to benefit even more. CRINA® Poultry Plus is registered as zootechnical additive in Europe.

Increasing gut performance in poultry is something we are passionate about. We know that it makes a real difference to profits for our customers.

We are constantly searching for new and better ways to produce more efficient birds. With CRINA® Poultry Plus this is exactly what we were aiming for.

By combining two already-proven we created a product that has shown to provide significant improvements. Its two main ingredients complement each other to deliver consistent performance.

CRINA® Poultry is a flavoring additive comprising a specific blend of essential oil components including thymol, eugenol and piperine. These ingredients stimulate the production of digestive enzymes and improve the balance of gut microflor

Benzoic acid is the most effective organic acid for inclusion in poultry diets. It has shown a strong anti-microbial effect, particularly againstE.coli and campylobacter.

The result is greater and more consistent digestive efficiency.


Faster-growing, more efficient birds

CRINA® Poultry Plus can be added to diets from starter to withdrawal rations.

Trial results have shown:

  • Greater daily liveweight gain
  • Increased feed conversion
  • Superior control of pathogenic bacteria
  • Higher profits, with an average return on investment of 5:1.

CRINA® Poultry Plus helps producers maintain performance in the post-antibiotic era.

CRINA® Digest

The new cost-effective essential oils solution to step-up poultry digestion

  • A unique and complementary combination of three essential oil compounds: thymol, eugenol and piperine
  • Microencapsulation technology ensuring controlled release of bioactives along the gastrointestinal tract
  • A solution to step-up digestion in all poultry species

Intestinal Controlled Release

The microencapsulation technology of Crina® Digest ensures gradual diffusion of the essential oil actives along the gastrointestinal tract for a better digestion.

Optimum Nutrient Digestibility

Crina® Digest improves digestive functions with piperine, which interacts with cell wall receptors in the pancreas and stimulates increased secretions of key digestive enzymes including lipase, amylase and trypsin. Thus, the intestinal absorption of nutrients is enhanced.

Modulation of the gut microbiota

Thymol and Eugenol contribute to a balanced intestinal microbiota through their recognized properties of moderating the development of specific classes of bacteria (eg: Clostridium perfringens).

Meta-analysis of 6 broiler trials run in Europe in 2018 (p<0.05)

  • Better feed conversion ratio: -1.4%
  • Return on investment: 4€ increased profit for 1€ invested

CRINA® Swine

Improved feed use makes a big impact on profits. To see how you can benefit from this, have a look at our CRINA® offering for swine.

Essential oils and their components are renowned for their impact on gut health.

Main Benefits

Swine have specific needs at different stages of development. Recognizing this, we offer finely-tuned blends for piglets, for finishing pigs and for sows. This ensures the maximum benefit for all animals specific to their requirements.

Piglets are at greater risk of microbial health challenges around the time of weaning. CRINA® Piglets has been shown to help reduce this risk.

In finishing pigs, the goal is high feed conversion. CRINA® Finishing Pigs has been shown to specifically improve digestive efficiency.

In sow units, the addition of CRINA® Finishing Pigs and Sows helped sows achieve their lactation potential more easily by stimulating feed intakes and reducing loss of body weight during lactation.

Put all these factors together, and CRINA® Swine ensures a good return on your investment.

CRINA® Ruminants

Dairy farmers and feed compounders alike want to maintain effective margins. CRINA® Ruminants helps them achieve this.

Dairy farmers want to achieve higher production and better feed efficiency in order to increase their returns. Feed manufacturers want the flexibility to vary the ingredients they use. This allows them to deliver quality feed and reduce costs.

Increasing dairy cow efficiency

CRINA® Ruminants is a precise blend of essential oil components.

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.

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.
