Dried Egg Product is considered the gold standard of protein quality in pet food. It can be supplied as whole egg, egg white, or yolk fractions, provides all essential amino acids in a balanced profile, and reaches very high digestibility. In practical formulation work, it is one of the clearest markers of a premium animal-derived protein source.

VetKriter Assessment
5/5 quality score
Egg ingredients combine top amino acid quality with strong digestibility and useful micronutrients such as choline, selenium, riboflavin, and fat-soluble vitamins. In ingredient evaluation, they sit near the top of the protein hierarchy.
Protein Quality Comparison

Nutritional Profile
- Complete amino acid profile: all essential amino acids in highly usable proportions
- Choline: supports liver function and neurotransmitter synthesis
- Lutein and zeaxanthin: present especially in yolk fractions
- Natural vitamin D: valuable animal-source micronutrient contribution
- Selenium: contributes to antioxidant defense systems
Frequently Asked Questions
- Is egg allergenic for dogs and cats? Egg allergy exists but is far less common than many owners assume. In strict elimination trials, egg must still be excluded like any other suspect protein.
- Why is egg used as a protein reference? Because its amino acid pattern and biological value make it a practical benchmark for comparing other protein sources.
