Creatine is widely recognized for its role in human sports nutrition, but its potential in animal nutrition is gaining increasing attention. As an essential compound for energy metabolism, creatine supplementation in livestock and aquaculture feeds can enhance growth performance, feed efficiency, and overall animal health. This article explores the applications and benefits of creatine in animal nutrition, particularly for poultry, swine, ruminants, and aquatic species.

1. The Role of Creatine in Animal Metabolism

Creatine plays a vital role in ATP (adenosine triphosphate) regeneration, which fuels muscle contractions, cellular functions, and metabolic activities in animals. including:

Enhanced muscle growth and lean meat production

Optimized feed conversion ratios (FCR), reducing feed costs

Reduced muscle fatigue and stress, especially during transport or heat exposure

2. Applications of Creatine in Animal Nutrition

2.1 Poultry Nutrition (Broilers & Layers)

Layers: It improves egg production and shell quality by supporting energy metabolism.

Heat stress resistance: Creatine helps mitigate heat stress in poultry by optimizing cellular hydration and ATP regeneration.

2.2 Swine Feed (Piglets & Sows)

Piglets: Creatine supplementation boosts early growth performance and reduces mortality rates during weaning.

Breeding sows: Supports reproductive health, improving litter size and piglet viability.

2.3 Ruminant Nutrition (Cattle & Dairy Cows)

Beef cattle: Creatine helps improve muscle mass development and carcass quality.

Dairy cows: It supports milk production efficiency by enhancing energy metabolism.

Calves: Creatine supplementation can strengthen immunity and promote healthier growth.

2.4 Aquaculture (Fish & Shrimp Feeds)

Fish: Creatine increases swimming endurance, improves growth rates, and enhances survival rates.

Shrimp: It boosts molting efficiency and enhances stress resistance in high-density farming conditions.

3. Key Benefits of Creatine in Animal Feed

Enhanced Growth and Muscle Development – Increases lean body mass and improves meat quality.

Better Feed Efficiency – Optimizes nutrient absorption and utilization.

Increased Stress Resistance – Helps animals cope with transport, heat, and environmental challenges.

Reduced Dependency on Antibiotics – Supports natural metabolic functions and immunity.

Cost-Effective Production – Improves feed conversion, reducing overall feed costs.

4. Recommended Dosage of Creatine in Animal Feeds

The ideal creatine inclusion levels vary depending on species and production goals:

Poultry: 0.05% - 0.15% of total feed formulation

Swine: 0.08% - 0.20%

Ruminants: 0.10% - 0.30%

Aquaculture: 0.05% - 0.12%

Creatine supplementation in livestock and aquaculture nutrition offers numerous benefits, including improved growth, feed efficiency, and stress resistance. As the global demand for sustainable and high-quality animal protein increases, the use of creatine in animal feeds presents a promising solution for farmers and feed manufacturers.
