Application of Lysine Feed Additive

Why Lysine?

How to Improve Poultry feed Performance

Lysine is an essential amino acid and must be supplied by the cow's diet as it cannot be produced naturally within the body. To improve poultry feed performance, lysine can be added to the feed. Lysine is an essential amino acid that poultry require for normal growth and physiological functions. By adding sufficient lysine to the feed, poultry can have better growth performance and immune function.

Overall, adding lysine to poultry feed and ensuring a balanced mix of other essential nutrients and high-quality ingredients can help to improve poultry feed performance. Producers may:

· Feed diets lower in crude protein

· Reduce the overall nitrogen excretion from cows into the environment

· Potentially see improved health benefits

Lysine Deficient Diets

Producers often wonder how to improve poultry feed efficiency. Many poultry are fed diets that do not provide sufficient amounts of lysine. The graphic below looks at amino acids as a percent of composition. It is not possible to provide enough lysine with corn and soybean meal alone without overfeeding other nutrients, feeding overly expensive diets or causing health problems. A nutritionist's goal is to match up protein sources with the poultry's lysine requirement and do so in the most efficient and cost-effective manner.

How Much is Really Needed?

The amount of lysine needed in poultry feed depends on various factors such as the age, 

weight, and type of poultry, as well as the ingredients used in the feed. Generally, the

recommended lysine levels for poultry feed are as follows:

Poultry Type         Age        Lysine Requirement

Broiler Chickens    Starter          1.0% - 1.2%

                               Grower          0.9% - 1.0%

                               Finisher         0.7% - 0.8%

Laying Hens    Over 20 weeks    0.7% - 0.8%

Turkeys                   Starter           1.2% - 1.3%

                                Grower          1.0% - 1.2%

Finisher              0.8% - 1.0%

It is important to consult with a poultry nutritionist or veterinarian to determine the

appropriate amount of lysine needed based on the specific needs of your poultry.

Increase Lysine, Increase Profits

Increasing the intake of lysine can improve the growth rate and meat quality of poultry, thereby increasing the profits of poultry farming. If you are a poultry farmer or entrepreneur, you may consider adding lysine-rich ingredients to poultry feed, such as soybean meal, fish meal, and methionine. At the same time, it is important to balance other feed ingredients to ensure that poultry obtain comprehensive nutrition.
