Flavonoids are the main medicinal components in Ginkgo biloba. Flavonoids accounted for 5.9% of Ginkgo Leaf extract. In addition to being used as medicines at home and abroad, ginkgo extract products are also widely used in food and cosmetics. Ginkgo biloba extract has been gradually applied to livestock and poultry production in recent years.
Are ginkgo biloba good for you?
There are about 40 kinds of flavonoids in Ginkgo biloba extract, including 32 kinds of monoflavonoids, 6 kinds of flavonoids, and 4 kinds of catechins. Mainly for scavenging free radicals, anti-lipid peroxidation and so on. Flavonoids are the main chemical components of Ginkgo biloba that exert various unique pharmacological activities.
Role in Pig Production
1. Improve immunity
0.2%-0.3% Ginkgo biloba extract was added to the diet of 25-day-old weaned piglets. Feeding for 28 days could significantly increase the blood erythrocyte count, lymphocyte count, hemoglobin concentration and lymphocyte percentage in weaned piglets. This enhances the immune function of weaned piglets. In addition, Ginkgo biloba extract can be used as an immune booster to improve the efficacy of vaccines.
2. Antibacterial and anti-inflammatory
Ginkgo biloba extract (EGB) has in vitro antibacterial effects on several piglet intestinal bacteria. According to the research results, Ginkgo biloba extract has a good inhibitory effect on common polluting bacteria, and its inhibitory strength is related to its concentration.
3. growth-promoting effect
Ginkgo biloba extract is rich in nutrients, which can improve the nutritional value of the feed. At the same time, it can regulate intestinal flora, thereby promoting the growth and reproduction of animals. The study found that adding Ginkgo biloba extract to the diet can improve weaned piglets' digestion and absorption capacity.
In recent years, Ginkgo biloba extract, a safe and green plant, has been gradually introduced into livestock and poultry production as an alternative to antibiotics. However, ginkgo Biloba's processing and production scale in China is small and scattered, and the technology is also relatively backward. The extraction process still needs to be optimized. Different types of Ginkgo biloba leaves in different regions have other active ingredients such as flavonoids and polysaccharides in different seasons. Further improvement is needed in the formulation of use standards. Giving full play to the uniqueness of China's ginkgo resources and vigorously developing the application of ginkgo leaf extract to replace antibiotics in the field of aquaculture has a good development prospect.
