| Definition |
Animal nutrition is the science of supplying animals with energy, protein, amino acids, minerals, vitamins, water, and other functional nutrients required for maintenance, growth, reproduction, health, and production. |
Balanced nutrition supports productivity while reducing nutrient waste, production losses, and avoidable health problems. |
Food and Agriculture Organization of the United Nations (FAO); National Research Council animal nutrition references. |
| Main Production Species |
The scope includes pigs, poultry, cattle, sheep, goats, rabbits, aquatic animals, horses, companion animals, and other farmed or managed species. |
Different species and production stages have different digestive systems, nutrient requirements, feed ingredients, and safety risks. |
FAO; Chinese feed and animal husbandry regulatory classifications. |
| Core Nutrient Groups |
Energy-yielding nutrients, crude protein, essential amino acids, fats, fiber, macro-minerals, trace minerals, vitamins, water, and selected feed additives. |
Deficiency, excess, or imbalance can affect growth rate, feed conversion, fertility, bone development, immunity, and product quality. |
FAO; Chinese feed formulation and feed evaluation standards. |
| Feed Categories |
Common categories include single feed ingredients, concentrated feeds, compound feeds, additive premixes, complete feeds, and supplementary feeds. |
Clear categorization supports correct formulation, labeling, quality control, and regulatory compliance. |

| Feed Formulation |
Formulation matches nutrient supply with species, breed or genetic line, body weight, production stage, environmental conditions, and target performance. |
Precision formulation can improve feed efficiency and help control feed cost without compromising animal performance. |
National and sector-specific Chinese feeding standards; FAO feed formulation guidance. |
| Feed Safety |
Safety management covers contaminants and prohibited substances, including mycotoxins, heavy metals, excessive pesticide residues, microorganisms, and unauthorized additives. |
Safe feed protects animal health, reduces food-chain risks, and supports the safety of meat, milk, eggs, and aquatic products. |
GB 13078-2017, Hygienical Standard for Feeds; relevant Chinese maximum-residue and contaminant standards. |
| Feed Additives |
Feed additives may include nutritional additives, sensory or technological additives, and other permitted substances listed or approved under China’s regulatory system. |
Controlled use can support nutrient balance, feed stability, processing quality, and animal performance; unauthorized use creates compliance and safety risks. |

| Antibiotic Reduction |
China implemented a national feed-antibiotic reduction policy, including the removal of growth-promoting antibiotic feed additives from the permitted feed-additive framework from 2020, while veterinary medicines remain subject to separate rules. |
The policy increases the importance of biosecurity, vaccination, hygiene, farm management, and evidence-based nutritional strategies. |

| Animal Health and Welfare |
Nutrition is linked with gut function, immune response, metabolic health, reproductive performance, stress resilience, and the physical quality of animal products. |
Healthy animals generally use nutrients more efficiently and are less vulnerable to production losses associated with nutritional disorders. |
FAO; World Organisation for Animal Health (WOAH) animal health and welfare principles. |
| Environmental Sustainability |
Sustainable animal nutrition focuses on efficient use of protein and energy, lower nitrogen and phosphorus losses, responsible sourcing of ingredients, and improved feed conversion. |
Better nutrient utilization can reduce emissions and nutrient discharge per unit of meat, milk, eggs, or aquatic production. |
FAO; United Nations Environment Programme; Chinese agricultural and feed-efficiency guidance. |
| Quality Control Indicators |
Typical indicators include moisture, crude protein, crude fat, crude fiber, ash, amino-acid levels, mineral content, microbial quality, mycotoxins, and label accuracy. |
Routine testing verifies that feed conforms to specifications and helps identify adulteration, deterioration, contamination, or formulation errors. |
Chinese feed testing methods and relevant national standards issued by the State Administration for Market Regulation and MARA. |
| Regulatory Scope in China |
China regulates feed production, licensing, feed additives, product quality, labeling, inspection, traceability, storage, transport, and the use of prohibited substances. |
Compliance is essential for market access and for protecting animal health, consumer safety, and the integrity of the feed supply chain. |
