Quick answer: Lysine is the first limiting amino acid in most pig diets because cereals such as corn, wheat and cassava are low in it. Adding feed-grade L-lysine HCl (98.5% pure, 78.8% lysine) lets farmers lower soybean meal and crude protein while keeping growth and lean meat high, cutting feed cost and nitrogen in manure.

Key facts

Status in pigs	First limiting amino acid
Product	L-lysine HCl 98.5% (78.8% lysine)
Main benefits	Growth, lean meat, feed efficiency
Cost effect	Less soybean meal per tonne
Environmental benefit	Less nitrogen in manure
Packing	25 kg bags

Why pigs need lysine

Lysine is essential for muscle growth, and pigs cannot make it. Pig diets are formulated around lysine first, then other amino acids are set as ratios to lysine (the “ideal protein” concept).

How L-lysine lowers feed cost

Approach	Effect
Meet lysine with soybean meal only	High crude protein, higher cost, more nitrogen waste
Use L-lysine HCl plus less soybean meal	Same lysine, lower crude protein, lower cost

Lysine needs by stage

Piglets need the most lysine per kilogram of feed, followed by growers and then finishers. Lactating sows also have high needs. Your nutritionist sets the exact levels using standardised ileal digestible (SID) lysine values.

L-lysine HCl vs lysine sulphate

L-lysine HCl: 98.5% purity, about 78.8% lysine, the most concentrated form.
L-lysine sulphate: lower lysine (about 50–55%) plus other fermentation nutrients; adjust inclusion rates accordingly.

Frequently asked questions

Why is lysine important for pigs?

Lysine is the first limiting amino acid in most pig diets and is essential for muscle growth and lean meat.

How does L-lysine reduce feed costs?

It lets you meet lysine needs with less soybean meal, lowering crude protein and ingredient cost.

What is SID lysine?

Standardised ileal digestible lysine, the amount of lysine actually absorbed, used by nutritionists to formulate pig diets.
