Protein is the crucial growth factor in animal nutrition. Protein supplied to animals comes in three main forms: Crude protein, Amino Acids, and Peptides.
- Crude protein: Although crude protein is the traditional and common protein supply source, it is now facing sustainability and efficiency problems. Animal-based protein is depleting and becoming more costly. On the other hand, plant-based protein contains anti-nutritional factors and lacks palatability features.
- Free Amino Acids: Introduced to the feed industry in the 1950s, Free Amino Acids are positioned to complement crude protein by supplementing the insufficient amino acids . However, high technology barriers mean that only a few big companies can commercially synthesize Amino acids, with their focus primarily on Essential Amino Acids (EAA).
- Peptides: Peptides are a short chain consisting of 2-71 Amino Acids . Peptides offer a rich multitude of benefits, including providing nutrition, boosting palatability, gut health functions, and enhancing immunity, etc. With an abundance of advantages, peptides are gaining increasing interest with high growth potential.
Figure 1. Crude protein, Peptide, and Amino Acids (AAs) markets overview
This article represents the first of VNF’s Shrimp-based Functional Peptides series, where we introduce the functions, mechanisms, and competitive advantages of peptides as the much-needed last piece of the global protein market. Let’s first be on the same page with an understanding of protein’s journey in the body!
PROTEIN CATABOLISM AND ANABOLISM
Figure 2: Protein catabolism and anabolism
Upon entering the stomach, Protein is broken down by digestive enzymes into Peptides and free AAs , in which only Di/Tri-Peptides and AAs can be directly absorbed through intestinal wall  to be used to build new proteins for the body. Longer chain peptides and undigested protein that are not digested  once reaching the colon will create a favorable environment for pathogenic bacteria to proliferate. Resulting consequences include detrimental harm to the animal’s health, environment, and subsequently, farmers’ profit (see figure 3 for more details).
Considering crude protein digestion requires many resources (enzymes, energy expended, time), it is not optimal nutrition. Thus, a more efficient and sustainable solution is urgently needed.
Figure 3. Excess protein discharge and its consequences
Free Amino Acids provide complementary values to Crude protein, such as improving digestibility, mitigating health risks from excess protein, etc. Animals need more than 20 AAs to synthesize protein , yet only 8 AAs are commercialized to this day. Free Amino Acids are therefore not a stand-alone solution.
VNF’S SHRIMP-BASED FUNCTIONAL PEPTIDES
We are confident that VNF’s shrimp-based functional peptides will achieve optimal protein usage by animals. VNF’s peptides help diversify the AA profile and improve palatability, digestibility, and overall health performance. Besides, we have successfully built a sustainable and cost-effective supply solution thanks to our proprietary biotechnologies and zero-waste production mindset.
