Methionine in Broiler Feed: Why DL-Methionine Matters for Growth and Feathering
Quick answer: Methionine is usually the first limiting amino acid in corn–soybean broiler diets, so supplementing DL-methionine improves growth, breast meat yield, feathering and feed conversion. Feed-grade DL-methionine is 99% pure and added in small amounts set by the nutritionist. Too little methionine slows growth and causes poor feathering; balancing it lets you lower total dietary protein.

Why broilers need extra methionine
Corn and soybean meal, the base of most broiler feed, are naturally low in methionine relative to what fast-growing birds need. Methionine is used for muscle protein, feather keratin (with cystine) and many metabolic functions, so a shortfall limits performance even when total protein looks adequate.
Benefits of DL-methionine supplementation
- Faster growth and better feed conversion ratio (FCR)
- Higher breast meat yield
- Better feather cover, which also improves heat tolerance
- Lower crude protein in the diet, which reduces cost and ammonia
Methionine needs change with age
| Phase | Requirement |
|---|---|
| Starter | Highest per kg of feed |
| Grower | Moderate |
| Finisher | Lower per kg, but still essential for yield |
Exact levels come from breed guidelines and your nutritionist.
Buying DL-methionine
Look for 99% purity, a free-flowing powder and a certificate of analysis. See our feed-grade DL-methionine and our DL-methionine vs L-lysine guide.
Frequently asked questions
Why is methionine important in broiler feed?
It is usually the first limiting amino acid, so it controls growth, breast meat yield and feathering in corn–soybean diets.
What are signs of methionine deficiency in chickens?
Slower growth, poor feathering, lower breast meat yield and worse feed conversion.
Can DL-methionine reduce feed costs?
Yes. Balancing methionine lets nutritionists lower total protein while keeping performance.
