Natural Feed Additives - Application of Astragalus in Swine Production

Astragalus membranaceus is a dry root of the leguminous Astragalus mongholicus or Astragalus membranaceus. Mongolian astragalus contains saponins, polysaccharides, flavonoids, amino acids, and inorganics. It contains 21 kinds of amino acids, of which 7 are high in content, and also contains betaine, linolenic acid, and other inorganic elements such as iron, manganese, and zinc. Astragalus membranaceus contains baicalin I, II, carotenoid, β-gutenol, palmitic acid, sucrose, choline, betaine, folic acid, glucuronic acid, amino acids, bittersin, etc. (Chun Chunru et al.: modern practical Chinese herbal medicine Quality Control Technology, People's Medical Publishing House, 2000, P890)
Modern studies have shown that Astragalus has strong cardiac diuretic and antihypertensive effects, and has antibacterial effects on dysentery, anthrax, diphtheria, staphylococcus, streptococcus, and pneumococcus. As a feed additive, it has the effect of accelerating the metabolism of organisms and promoting the growth and development of livestock and poultry. Adding 600-800 mg/kg Chinese herbal additive based on astragalus to pig diets, pigs can increase weight gain by 20% to 30%, feed utilization rate by 15%, and 2.5% in sow diets. It can increase milk production by 22.7% for sows, and 19.7% for weaners at 35 days of age. (Edited by Li Shangbo et al., “Top Ten High-efficiency Feed Additives for Livestock and Poultry, Liaoning Science Press, 2000, P199) According to Meng Zhaoju, using single-flavored baicalin as feed additives, the additive amount was 1%, and the daily weight gain was 23.6% higher than that of the control group. The feed cycle was shortened by 17 days, the feed conversion rate was increased by 13.3%, and the economic benefit was increased by 41%.

[Usage] According to the pig per kg body weight 0.5-1g mix feeding.
[Process] total research to fine.
[Illustration] The test results show that the weight gain can be increased by about 20%.
2, growing pigs promote Changling
[Source] According to Delong County Agricultural Bureau Zhu Longsheng reported.
[Composition] Astragalus membranaceus, Radix Paeoniae Alba, Radix Polygoni multiflori, Guan Zhong, five kinds of trace elements, and double enzyme protein powder.
[function] Qi and blood, insecticide. For growing pigs to promote growth.
[Usage] Add 1% to feed in the diet.
[Process] a total of fine research, mixing evenly.
[Note] Zhu Longsheng et al. ("Zhejiang Animal Husbandry and Veterinary Medicine" (2): 10-11, 1995) reported that the daily gain of experimental pigs after feeding this product was increased by 16.95%; the feed conversion rate was increased by an average of 15.2%, and the feed efficiency was very significant.
3, weight gain and disease resistance additives
[Source] "Chinese Herbal Feed Additives"
[Composition] Astragalus 200g, Jianqu 200g, Chinese slag 200g, Malt 200g, Polygonum multiflorum 100g, Guanzhong 100g, Tonglea 300g, dried tangerine peel 100g, white peony 200g, pine needle 300g, Daqingye 200g.
[function] Bugan Yishen, spleen digestion, qi solid table, detoxification insecticide.
[Usage] Pharmacopoeia total fine, added by 10% of the amount of feed. (Note: This additive can be reduced)
[Illustration] According to the 60-day test results of 40 pigs of 30 days old, the test group gained 35 g per head per day compared to the control group. During the epidemic, there was no hair disease in the test group and the protection rate was 100%. In the control group, there were 9 cases and the incidence rate was 45%.
