Proteins in the Feed Industry: Quality Matters – and How Celitron’s ISS AGRI Delivers with Feather Meal Processing

12-06-2025

In the fast-evolving animal feed industry, proteins are more than just a macronutrient—they are the cornerstone of efficient growth, health, and productivity in livestock. But not all proteins are created equal. As demand grows for sustainable protein sources that deliver high digestibility and nutritional value, innovations in animal byproduct processing are leading the way.
Why Protein Quality Is Essential in Animal Feed
Feed-grade protein must meet three key criteria:
1. High digestibility, especially for monogastric animals like poultry and swine.
2. Balanced amino acid composition, focusing on essential amino acids like lysine, methionine, and histidine.
3. Low contamination with heat-induced byproducts, such as oxidation compounds or unnatural amino acids.
These factors not only impact animal health but also influence feed efficiency, cost, and market competitiveness. In this context, feather meal—a byproduct of the poultry industry—presents a massive untapped opportunity when processed correctly.
The Challenge with Raw Feather Meal
Chicken feathers contain up to 90% keratin protein, but in their natural state, they are virtually indigestible. Without adequate processing, raw feathers cannot be absorbed by animals and may even negatively affect performance. Traditional hydrolysis methods often fall short due to overprocessing, which can damage amino acid quality, or underprocessing, which leads to poor digestibility.
The Celitron Advantage: Thermally Hydrolyzed Feather Meal with ISS AGRI
Celitron’s ISS AGRI system offers a cutting-edge solution for turning waste feathers into high-quality protein meals through thermal hydrolysis under controlled pressure and temperature. This process transforms keratin into a digestible, functional feed ingredient suitable for poultry, pigs, and aquaculture.
Key Benefits of Celitron’s Feather Processing:
• Consistently High Pepsin Digestibility: Celitron’s technology achieves up to 85% pepsin digestibility when operated at optimized, outperforming traditional systems.
• Preservation of Amino Acid Quality: Proper hydrolysis avoids degradation of sensitive amino acids and minimizes the formation of undesirable byproducts like lanthionine, which can indicate protein damage.
• No Need for Chemical Additives: Unlike chemical pre-treatments that may cause toxic residues or amino acid losses, Celitron’s process relies purely on steam sterilization and mechanical breakdown.
A Short Study: ISS AGRI vs. Traditional Hydrolysis
Traditional autoclave methods sometimes fail to reach the necessary protein bioavailability. Studies show that overprocessed feather meals lose vital amino acids like cystine and methionine, and generate lower growth rates in animals. In contrast, ISS AGRI's automated thermal cycle maintains optimal conditions to avoid excessive cross-linking and ensures superior digestibility.
A side-by-side comparison of enzymatic digestibility and protein integrity confirms Celitron’s process meets or exceeds industry standards for feather meal used in pet food and animal feed.
Meeting the Needs of a Growing Global Market
According to recent industry data, global demand for high-quality protein meals continues to rise, especially in the pet food, poultry, and aquafeed sectors. Celitron’s rendering equipment not only helps clients reduce waste but also create high-value products from what was previously a disposal cost.
