What are acidifiers?

• Acidifiers are feed additives composed

mainly of organic acids and their salts

• Increasing use in aquaculture during the

last 10 years

• Typical dosages range from 1 kg/t (0.1%)

to 20 kg/t (2%)

• New generation Acidifiers contain

additional encapsulated organic acids and

essential oils and are formed into

complexes to improve technological

properties



How does Ca®Plus ME work?

Ca®Plus ME consists of 3 active ingredient groups and is multifunctional:

Free organic acids and their salts

Microencapsulated acid

Microencapsulated essential oils

Ca®Plus ME active ingredients are selected to act in the feed, mouth,stomach as well as in the small and large intestine

Ca®Plus ME is one hundred percent active for the animals and supplieshighly available calcium for a successful diet formulation

Ca®Plus ME is an easy to handle, non corrosive feed additive which isdeveloped for safe handling

Ca®Plus ME helps to reduce buffering capacity in the feed

Where is Ca®Plus ME working?

Feed

• Antimicrobial effect

• Nutritional effects (Ca minerals/energy)

• Reduction of buffering capacity

Stomach

• Reduction of the pH (formic, lactic, citric acid)

• Activation of proteolytic enzymes (better protein digestion)

Small Intestine

• Antimicrobial effect (e.g. gram negative bacteria with lactic acid, and local pH reduction)

• Stimulation of pancreas secretion (pH effect feedback from the stomach); better Ca and P digestion

Large Intestine

• Antimicrobial effects due to microencapsulated essential oils and strong organic acids

• Stimulation of non specific immunity (lactic acid)

7 Feed preservation and further effects of new generation acidifiers on aquaculture productions


• Essential oils increase permeability of the cell wall of pathogenic bacteria

- essential oils have the ability to change the outer membrane of gram-

negative bacteria

- resulting in the inactivation of the cell protein

• Organic acids, now also in dissociated form (anion- and cation+), can pass

through the cell wall

- therefore also more efficiency at higher pH levels for instance in the

intestine

Future of acidifiers in aqua feed

• Most acidifiers in the market are multi-species products.

Only few acidifiers are adapted to specific aquaculture species

demands.

• With future growth of aquaculture this will lead to more

specialization, also in feed formulation and feed additive

development

• Design of aquaculture feed will become more and more specific,

regarding species, production system, system intensity, etc.

• More R&D efforts required to develop special acidifiers for future

aquafeed markets



Take home message

• New generation Acidifiers:

- with encapsulated organic acids and essential oils

• Effective in the feed and in the animal:

- Antimicrobial effect

- Stimulation of proteolytic enzymes

- Immune stimulation

• Efficient for the farmer:

- Increase growth performance

- Increased feed utilization

- Reduced mortality

- Less need of antibiotics
