Application of Garlic Extract in Feed Additives

Author : Naturalin　　Date :　Click : times

With the global focus on food safety and the phasing out of antibiotic growth promoters in animal husbandry, natural plant extracts have become ideal alternatives. Garlic extract, rich in bioactive compounds like allicin, has attracted wide attention in the feed industry for its multiple benefits to animal growth, health and product quality. This article explores its core value, action mechanisms, practical applications and market prospects, highlighting its role in advancing sustainable animal husbandry.





The Core Advantages: Why Garlic Extract Stands Out


The popularity of garlic extract in feed additives lies in its rich and stable bioactive components, mainly organosulfur compounds represented by allicin. Compared with synthetic additives, it is non-toxic, residue-free and compatible with animals' natural physiological needs, thus effectively solving the problems of antibiotic residues and bacterial resistance in traditional breeding. In addition, by-products of garlic processing (such as garlic skin) also contain similar active ingredients, which enables resource recycling and reduces production costs. From a market perspective, the global garlic extract market is expanding steadily, and the feed additive sector, driven by policies and industrial demand, shows strong growth potential—laying a foundation for its wider application in animal husbandry.

Mechanisms of Action: How Garlic Extract Benefits Animal Husbandry


The above core advantages of garlic extract are supported by its diverse biological mechanisms, which comprehensively regulate the physiological functions of animals to exert positive effects in breeding:

1. Regulating Gut Microecology and Improving Nutrient Utilization
For ruminants, garlic extract acts as a urease inhibitor, reducing ammonia nitrogen production in the rumen and regulating the rumen microbial community by inhibiting harmful bacteria and promoting beneficial ones, thus improving the utilization efficiency of non-protein nitrogen. For monogastric animals and aquatic products, it can also balance intestinal flora, promote the proliferation of beneficial bacteria (such as lactic acid bacteria) and inhibit pathogenic bacteria (such as Vibrio), optimizing intestinal structure and nutrient absorption efficiency.

2. Enhancing Immunity and Antioxidant Capacity
Garlic extract can significantly enhance animal immunity and antioxidant capacity. In broiler breeding, adding garlic powder increases blood immunoglobulin levels and enhances humoral immunity. For aquatic animals like shrimp, it boosts the activity of non-specific defense enzymes and activates the endogenous antioxidant system, reducing oxidative stress damage caused by environmental factors such as low temperatures. It also lowers the level of malondialdehyde (an oxidative stress marker) in animal blood, maintaining the balance of the body's oxidative system.

3. Promoting Growth Performance and Improving Product Quality
By improving nutrient utilization and regulating physiological functions, garlic extract effectively promotes animal growth. Adding garlic by-products or extracts to ruminant diets can increase average daily gain and improve feed conversion ratio. For broilers, garlic powder supplementation enhances growth performance and improves carcass traits. In terms of product quality, it increases the content of beneficial fatty acids and essential amino acids in meat and milk, making animal products more beneficial to human health.

4. Reducing Environmental Pollution
A prominent advantage of garlic extract in ruminant breeding is its ability to reduce methane emissions. Its organosulfur compounds inhibit the growth of methanogenic archaea, which is in line with the global goal of carbon neutrality in animal husbandry.

Market Prospects and Future Trends


The positive effects of garlic extract in practical breeding have laid a solid foundation for its market development. Driven by global policies on food safety and green breeding, as well as strong market demand, the application of garlic extract in feed additives has broad prospects. According to industry reports, the global garlic extract market is expected to grow steadily, with the feed additive sector's demand increasing from 31,000 tons in 2024 to 87,000 tons in 2030. Regional market dynamics show obvious differentiation: Asia, especially Southeast Asia and India, has become a core growth pole with a projected growth rate of 4.3%-6.8%, driven by the rapid development of the aquaculture industry and the industrialization transformation of animal husbandry. The African market is also growing at a steady rate of 4.0% due to the booming poultry industry. As the world's largest garlic producer, China has unique advantages in raw material supply and processing technology, laying a solid foundation for industrial upgrading. In addition, the continuous improvement of global feed safety supervision systems has raised the industry threshold, which is conducive to the development of enterprises with advanced technology and standardized production. At the same time, multinational enterprises are accelerating their layout in strategic regions such as Europe and ASEAN through localized operations, further promoting the global popularization of garlic extract feed additives.

In the future, the development of garlic extract feed additives will focus on three key directions: first, optimizing extraction processes (such as supercritical CO₂ extraction and water-oil miscible extraction) to further improve the purity and stability of active components; second, developing customized products for different species and growth stages, such as high-temperature-resistant coated products to adapt to feed processing conditions; third, strengthening research on the synergistic effects of garlic extract with other natural additives (such as thyme and probiotics) to enhance comprehensive application effects. With the deep integration of technological innovation and industrial chains, the application scenario of garlic extract will be further expanded, and it is expected to form a "garlic extract +" multi-field application pattern covering animal health, food safety and environmental protection.

Conclusion


To sum up, as a natural, safe and multi-functional feed additive, garlic extract plays an important role in regulating animal intestinal health, enhancing immunity, promoting growth and improving product quality. Its wide application in ruminants, poultry and aquatic products not only helps solve the problems of antibiotic residues and environmental pollution in traditional animal husbandry, but also effectively promotes the sustainable development of the industry. With continuous technological progress, improved industry standards, and favorable market and policy environments, garlic extract is expected to become a core product in the natural feed additive market, injecting strong impetus into the green transformation of global animal husbandry.
