SCarboxymethylLcysteine China Suppliers and Factory for Animal Health

Looking for high-quality S-Carboxymethyl-L-cysteine? As leading China suppliers and factory, we provide premium Carbocysteine for animal health to regulate mucus and boost GSH levels, ensuring respiratory protection for poultry and pets.

share:

S-(Carboxymethyl)-L-cysteine, widely recognized as Carbocysteine, is a high-performance cysteine derivative specifically engineered for the animal health and nutrition sector. Acting as a potent mucoregulator and antioxidant, it provides a sophisticated approach to managing respiratory health in livestock and pets, ensuring optimal airway clearance and mucosal protection through an indirect regulation mechanism.

Unlike traditional mucolytics, this advanced additive enhances intracellular glutathione (GSH) levels and suppresses pro-inflammatory cytokines, making it an ideal choice for chronic respiratory management and preventive antioxidant support. From poultry farms to aquaculture and pet care, it delivers a stable, safe, and efficient solution to improve animal welfare and overall productivity.

Key Advantages


Respiratory Protection

Reduces sputum viscosity and regulates mucus secretion to protect animals from chronic bronchitis and pneumonia.


Long-term Stability

Provides sustained action for chronic disease management, offering a more stable profile than rapid-acting agents.


Oxidative Stress Relief

Boosts GSH levels to mitigate oxidative damage caused by ammonia, dust, or high-density farming stress.


Immune Modulation

Strengthens mucosal immunity and potentially enhances the efficacy of respiratory vaccines in porcine species.


Superior Safety Profile

Significantly fewer gastrointestinal side effects compared to NAC, ensuring better tolerance in monogastric animals.


Broad Species Utility

Versatile application across poultry, swine, aquaculture, and companion animals for diverse health challenges.

Frequently Asked Questions

Q: How does S-(Carboxymethyl)-L-cysteine differ from NAC in feed additives?

S-(Carboxymethyl)-L-cysteine regulates mucus production indirectly and is better suited for long-term chronic management with fewer gastrointestinal side effects, whereas NAC acts rapidly by directly breaking down mucus.

Q: What is the recommended dosage for poultry to reduce ammonia-induced lesions?

The typical recommended dosage is 50–100 mg/kg added to broiler feed, administered for 5–7 days via drinking water or feed.

Q: Can this product be used in aquaculture environments?

Yes, feed supplementation at 200–300 mg/kg is effective in aquaculture to protect against oxidative stress during transport or poor water conditions, improving overall survival rates.

Q: Are there any drug interactions I should be aware of?

It is advised to avoid concurrent use with highly acidic agents (such as Vitamin C) or specific antibiotics like tetracyclines to ensure optimal absorption and efficacy.

Q: Does it have any impact on the weight gain of livestock?

Trial data indicates that by reducing respiratory lesions and oxidative stress, S-(Carboxymethyl)-L-cysteine can improve weight gain in broilers by approximately 5–8%.

Q: Is it safe for long-term use in companion animals?

Yes, due to its mild action and high safety profile, it is highly suitable for long-term management of chronic bronchitis in dogs and cats when administered at proper dosages.
