283630 SODIUM BICARBONATE FEED GRADE CAS:144-55-8

Feed-Grade Sodium Bicarbonate (Feed-Grade Baking Soda)

1. Basic Information •Chemical Name: Sodium Bicarbonate •Chemical Formula: NaHCO₃ •Molecular Weight: 84.01 g/mol •

Appearance: White, odorless, fine crystalline powder or granular solid; soluble in water (solubility increases with temperature) and insoluble in ethanol. •pH Value: Approximately 8.3 (for a 1% aqueous solution at 25°C), presenting weak alkalinity without strong corrosiveness, which is safe for animal digestive tracts.

2. Core Functions in Animal Husbandry Feed-grade sodium bicarbonate is a widely used feed additive and functional supplement in livestock and poultry breeding. Its main roles are closely linked to regulating animal physiology, improving feed utilization, and enhancing production performance:

(1) Regulate Ruminal/Intestinal pH and Maintain Digestive Health •For ruminant animals (cattle, sheep, goats): The rumen relies on a neutral-to-slightly-alkaline environment (optimal pH: 6.2–6.8) for the activity of fiber-decomposing bacteria (e.g., cellulolytic bacteria) and protozoa. When animals consume high-concentrate feeds (e.g., corn, wheat) or fermentable feeds, excessive lactic acid or volatile fatty acids (VFAs) may accumulate, leading to ruminal acidosis (pH < 5.5). Feed-grade sodium bicarbonate neutralizes excess acid, stabilizes rumen pH, and ensures the normal decomposition of cellulose, starch, and protein—thus preventing acidosis-related issues like reduced appetite, diarrhea, or laminitis. •For monogastric animals (pigs, chickens, ducks): It adjusts the pH of the gastrointestinal tract, alleviates gastric acid overproduction, and creates a suitable environment for digestive enzymes (e.g., pepsin, amylase) to function, reducing the risk of gastric ulcers or intestinal dysbiosis.

(2) Improve Feed Utilization and Nutrient Absorption •It promotes the activation of key enzymes in the digestive system (e.g., ruminal cellulase, pancreatic amylase) and enhances the breakdown of nutrients such as crude fiber, carbohydrates, and proteins. Studies have shown that adding an appropriate amount of feed-grade sodium bicarbonate to dairy cow diets can increase the digestibility of crude fiber by 5–10% and that of crude protein by 3–7%. •It chelates with trace elements (e.g., calcium, phosphorus, magnesium) in feeds to form water-soluble complexes, facilitating their absorption in the intestinal tract—addressing potential nutrient deficiencies caused by poor mineral solubility.

(3) Enhance Production Performance •Dairy animals: Stabilizes rumen function to increase dry matter intake (DMI) and milk yield (usually by 5–15%); reduces the content of somatic cells in milk, improving milk quality (e.g., maintaining normal milk protein and fat levels). •Meat animals (beef cattle, fattening pigs): Promotes nutrient conversion efficiency, accelerates weight gain (average daily gain can increase by 4–8%), and reduces feed conversion ratio (FCR)—lowering breeding costs. •Poultry (broilers, layers): Alleviates heat stress (see below) and maintains stable egg production rate; for broilers, it improves breast muscle development and reduces mortality caused by digestive disorders.

(4) Alleviate Heat Stress in Animals In high-temperature environments (e.g., summer), animals excrete large amounts of sodium and bicarbonate ions through respiration (panting) and sweat, leading to electrolyte imbalance and reduced performance. Feed-grade sodium bicarbonate: •Supplements sodium and bicarbonate ions, regulating the body’s acid-base balance and electrolyte equilibrium. •Reduces the respiratory rate of poultry and ruminants, alleviating the physiological burden caused by heat stress—helping animals maintain normal appetite and metabolism.

(5) Reduce Ammonia Emissions in Livestock Houses When mixed into manure, the weak alkalinity of sodium bicarbonate can inhibit the activity of urease (an enzyme that decomposes urea into ammonia), thereby reducing ammonia release in livestock houses. This improves the breeding environment, reduces respiratory diseases in animals, and lowers environmental pollution.

3. Application Guidelines

(1) Recommended Dosage (based on Feed Dry Matter Content) Animal Type Dosage Range (%) Key Notes Dairy Cows 0.8–1.5 Increase dosage appropriately when feeding high-concentrate diets (>60%). Beef Cattle (Fattening) 0.5–1.0 Avoid excessive use to prevent rumen pH from being too high (≥7.2). Sheep/Goats 0.5–1.2 Suitable for both grazing and intensive feeding systems. Fattening Pigs 0.3–0.8 Reduce dosage for weaned piglets (0.2–0.4%) to avoid intestinal discomfort. Layers/Broilers 0.2–0.5 Mix evenly with feed; avoid mixing with acidic additives (e.g., organic acids) directly.

(2) Mixing Methods •Dry mixing: Mix feed-grade sodium bicarbonate with complete feed (e.g., pellets, powder) in a mixer until uniform. Ensure the particle size of sodium bicarbonate matches the feed to prevent segregation. •Solution mixing: Dissolve it in clean water (concentration ≤5 clean water (concentration ≤5%) and spray it onto feed or add it to drinking water (for poultry or small ruminants). Avoid using hot water (>60°C), as high temperatures may cause NaHCO₃ to decompose into Na₂CO₃, CO₂, and H₂O—reducing effectiveness.

(3) Compatibility Precautions •Incompatible substances: Do not mix directly with strong acids (e.g., hydrochloric acid, sulfuric acid), acidic feed additives (e.g., citric acid, fumaric acid), or ammonium salts (e.g., ammonium chloride). Chemical reactions may occur, generating toxic gases (e.g., ammonia) or reducing the efficacy of both additives. •Compatible substances: Can be used together with electrolytes (e.g., potassium chloride), vitamins (e.g., vitamin C), and probiotics—synergistically improving animal health and performance. 4. Quality Standards Feed-grade sodium bicarbonate must comply with international or national feed additive standards to ensure safety and effectiveness. Taking China’s GB/T 8978-2018 and the European Union’s EC No. 152/2009 as examples, key quality indicators include: Indicator Requirement (Typical) Sodium Bicarbonate Content (on dry basis) ≥99.0% Moisture Content ≤0.5% Ash Content (after ignition) ≤0.1% Heavy metals (Pb) ≤10 mg/kg Arsenic (As) ≤2 mg/kg Chloride (as Cl⁻) ≤0.05% pH (1% aqueous solution) 8.0–8.5 5. Storage and Handling •Storage conditions: Store in a cool, dry, well-ventilated warehouse; avoid direct sunlight, high temperature, and moisture. The product is hygroscopic and may cake when exposed to humidity—affecting mixing uniformity. •

Packaging: Use sealed packaging (e.g., polyethylene bags with inner liners, paper-plastic composite bags) with a net weight of 25 kg,  or 1000 kg (bulk bags for industrial use). •Shelf life: Typically 24 months from the production date when stored in original sealed packaging. If the package is opened, use the product within 30 days to prevent moisture absorption and decomposition. •Safety tips: It is non-toxic and non-irritating, but avoid inhaling large amounts of powder (which may cause respiratory discomfort). In case of contact with eyes, rinse with plenty of water immediately. 6. Market and Regulatory Notes •It is recognized as a GRAS (Generally Recognized as Safe) feed additive by the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), with no residue risks when used as directed. •When purchasing, ensure the product is labeled with "Feed-Grade" (not industrial-grade or food-grade, as their impurity limits and particle sizes may not meet animal feed requirements). •

Comply with local breeding regulations: Some regions have specific dosage limits for ruminants or poultry—always refer to local agricultural department guidelines.
