Encapsulation of plant extracts in poultry industry : controlling release for maximum efficacy Logo Feedia

In the poultry industry, the use of plant extracts to improve the health, growth and performance of poultry has become commonplace. However, for these plant extracts to be truly effective, it is essential to ensure their stability during heat treatment and storage, and to control their release into the animals digestive systems. One innovative approach to achieving this is encapsulation. Encapsulation of plant extracts consists of enclosing the active compounds in a protective matrix. The plant extracts used may be essential oils, flavonoids, polyphenols, tannins, alkaloids or other bioactive compounds, and each type of extract may require a specific release approach.

Innovative concepts for greater efficiency

For several years, TECHNA's R&D teams have focused their efforts on studying various encapsulation technologies and a wide range of coating media (cellulose, lipid, protein, etc.). The overriding objective was to select the optimum combinations for encapsulating plant extracts, responding specifically to the requirements of the target species, while devising innovative release concepts such as 'Quick Release', 'Slow Release' and 'Delayed Release'. These advances are the result of a rigorous, methodical approach that has enabled these release concepts to be validated through meticulously designed in vitro tests carried out in-house at Techna's laboratory.

CAPS-QR "Quick Release": maximising Initial Absorption

Quick Release concept aims to rapidly release plant extracts as soon as they enter the animal's digestive system. This approach promotes immediate absorption of the active compounds, which can be useful for fast-acting plant extracts.

CAPS-SR "Slow Release": prolonging the Effect

Slow Release concept  involves the gradual release of plant extracts into the gastrointestinal tract of animals. This approach may be advantageous for plant extracts whose effect needs to last over an extended period.

CAPS-DR "Delayed Release": targeting the right place

 Controlled or delayed release concept allows plant extracts to be released in a specific way in certain parts of the animal’s digestive system, particularly the lower digestive tract.

Managing the integrity of poultry's digestive tract with the AVIANCE concept

Techna has developed delivery strategies designed to optimize the efficiency of plant extracts according to their target in the digestive tract. The AVIANCE product has benefited from this know-how and these delivery concepts to effectively exploit the aperitive, antioxidant and antibacterial properties of its components.

AVIANCE's main objective is to improve the functioning of the digestive system, maintain the balance of the intestinal flora and increase the absorption zones in the intestine. Its composition is based on an original formulation of aromatic phenolic compounds, optimally protected by encapsulation and the innovative "CAPS-SR" concept.

This process ensures a gradual and continuous release of the active ingredients, guaranteeing that the plant extracts reach all parts of the digestive system. This approach helps to minimize peaks and troughs in the absorption of active compounds, contributing to a better nutritional balance. In addition to effectively managing the release of plant extracts, AVIANCE's encapsulation and integrated concepts ensure the stability of its components during storage and the granulation process.

In conclusion, this innovative approach opens up new perspectives for the poultry industry, promoting more sustainable production and healthier poultry thanks to more effective and targeted feeding.
