DL Methionine Liquid 88%

Ingredient: DL Methionine 88%

Core Role of DL-Methionine

DL-methionine is an essential amino acid

 with two key physiological functions that

determine its indications:

Nutritional supplementation:

As a “first-limiting amino acid” in many feeds (e.g., corn-soybean meal diets), it promotes protein synthesis, supporting animal growth, muscle development, and production performance (e.g., egg laying in hens, milk production in cows).

Liver detoxification & metabolism regulation:

It provides methyl groups (a key substance for biochemical reactions) to assist in the metabolism of toxic substances (e.g., ammonia, mycotoxins) in the liver, and participates in the synthesis of choline (preventing fatty liver). It also lowers urine pH in companion animals (helping prevent struvite stones).

Indications (By Animal Category)

DL-Methionine Liquid 88% is mainly used for nutritional deficiency correction and metabolic function support, with targeted indications for different animals:

Livestock (Pigs, Cattle, Sheep)

Focus on supplementing methionine deficiency in feed, improving production performance, and protecting liver function.

Pigs:

Correction of methionine deficiency in corn-soybean meal diets: Promotes growth in weaned piglets and fattening pigs, increasing average daily gain (ADG) and reducing feed conversion ratio (FCR).

Prevention of fatty liver:

Assists in liver fat metabolism (provides methyl groups for choline synthesis), reducing liver fat infiltration caused by high-energy feed or mycotoxin exposure.

Improvement of sow reproductive performance:

Enhances milk protein synthesis during lactation, improving milk quality and reducing piglet mortality; supports follicle development in breeding sows.

Cattle/Sheep (Ruminants):

Supplementary nutrition for high-yield dairy cows:

Increases milk protein content (reducing the risk of “low-protein milk”) and supports milk production (especially in mid-lactation when amino acid demand peaks).

Prevention of nutritional liver insufficiency:

Alleviates liver metabolic disorders caused by methionine deficiency in high-forage diets (common in sheep), improving wool quality and weight gain.

Poultry (Chickens, Ducks, Geese)

The most widely used category, mainly addressing methionine deficiency in low-protein feeds and improving production performance.

Broilers:

Promotion of muscle growth:

Corrects methionine deficiency in cost-effective feeds (e.g., low-fishmeal diets), increasing breast muscle yield and reducing “stunted growth” in flocks.

Enhancement of immune function:

Supports the synthesis of immune proteins (e.g., antibodies), improving resistance to common diseases (e.g., Newcastle disease, coccidiosis) during the fattening period.

Laying Hens:

Improvement of egg quality and production: Increases egg weight, eggshell hardness, and protein content in egg whites; extends the peak laying period (reducing the decline in laying rate after 40 weeks of age).

Prevention of fatty liver hemorrhagic syndrome (FLHS):

Assists in liver lipid metabolism, reducing liver hemorrhage and necrosis caused by high-energy feed and high laying pressure.

Ducks/Geese:

Supplementary nutrition for meat ducks:

Promotes feather development and muscle growth, reducing the time to market; for laying ducks, it improves egg production stability.

Aquaculture (Fish, Shrimp)

Targeted at methionine deficiency in plant-based aquafeeds (e.g., soybean meal-based feeds) and improvement of stress resistance.

Farmed Fish (Tilapia, Salmon, Trout):

Correction of amino acid imbalance in plant-based feeds:

Promotes growth and feed utilization (reducing feed waste), improving fish weight gain and survival rate.

Enhancement of stress resistance:

Supports the synthesis of stress-related proteins, improving tolerance to environmental stress (e.g., low dissolved oxygen, temperature fluctuations) and reducing mortality during transport.

Shrimp (Penaeus vannamei, Macrobrachium rosenbergii):

Promotion of molting and growth:

Assists in exoskeleton synthesis (provides sulfur groups), improving molting frequency and survival rate; enhances resistance to Vibrio infection.
