The Claim
Soybean meal is the primary protein source in poultry diets, although alternative plant- and animal-based protein sources can be used depending on their availability, cost, and nutritional profile.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Chicken feed usually uses soybean meal for protein, but other plant or animal proteins can be swapped in depending on price, availability, and how nutritious they are.

What the research says
