Application of Schisandra Extract in Animal Husbandry

The extract of Schisandra chinensis is mainly obtained from mature Schisandra fruit through ethanol extraction, and its main active ingredients are lignans, such as schisandrin A, schisandrin B, schisandrin A, schisandrin B, schisandrin C, schisandrin Class A, has the function of protecting the liver.

Application of Schisandra Extract in Animal Husbandry

1. Application in laying hen production

The schisandra alcohol, vitamin C and vitamin E of Schisandra chinensis have excitatory breathing, excitatory uterine smooth muscle, protect liver and detoxify, promote liver glycogen decomposition, resist stress, increase appetite and adrenaline-like effects, can improve metabolic efficiency, promote follicular development and Adding 0.5% Schisandra to the feed of laying hens after ovulation, the egg production rate can be increased by 5% for 8 to 10 days. Studies have shown that adding 1% Schisandra to the feed can significantly improve the egg production rate of laying hens under hard heat stress conditions. Increase egg weight and egg production rate, reduce egg feed, and prolong egg production period.

2. Application in broiler production

First, Schisandra significantly improves the production performance of broilers. Adding 50mg/kg and 100mg/kg of Schisandra extract to broiler diets can effectively improve the production performance of broilers compared with the feed without adding Schisandra , can increase the weight of broilers by more than 100 grams, and the ratio of feed to meat can be reduced by 0.04 and 0.05 respectively.

Second, improve the intestinal microbial environment, enhance the body's immunity, and have antiviral effects. Adding 0.125% Schisandra extract to the diet can significantly increase the average daily gain of 4-6 week-old broilers, reduce the number of E. coli in the cecum, and facilitate the proliferation of Lactobacillus in the cecum. Adding 1% Schisandra chinensis in the total ration can improve the antibody titer of Newcastle disease in broiler chicken serum. Adding 50, 100, and 150 mg/kg of Schisandra extract to the broiler diet, the total number of diarrhea in the test group was reduced by 5%, 43.8% and 33.1% respectively compared with the control group. Adding 100mg/kg and 150mg/kg has the most obvious effect on preventing diarrhea. The schisandra extract can effectively prevent broiler chickens from diarrhea, improve the health status of broiler chickens, and has the effect of disease prevention and disease resistance.

Third, enhance the antioxidant effect of broilers. Schisandrin, the active ingredient of Schisandra chinensis, has strong antioxidant activity, and its antioxidant performance is stronger than that of vitamin E, and can effectively inhibit the production of malondialdehyde caused by free radicals and reduce lipids. Peroxide damage to cells. Addition experiments showed that adding 0.5% Schisandra chinensis to broiler diets had an antioxidant protective effect on liver and abdominal fat.

3. Application in pig production

Adding Schisandra extract to piglet diet can significantly improve the activity of superoxide dismutase and total antioxidant capacity in serum or tissue, and can significantly reduce the content of malondialdehyde in serum liver and heart, which is helpful for improving piglets The central nervous system, cardiovascular system and blood circulation ability play an important role in enhancing anti-oxidation. In addition, the daily weight gain ratio of the survival rate of piglets is higher than that of the control group, while the feed-to-meat ratio is lower than that of the control group. Experiments show that 0.125% Schisandra extract can enhance the humoral immunity and cellular immunity of growing and finishing pigs, and can reduce the use of antibiotics in the late growth and finishing period.

4. Application in ruminants

There are few studies on the application of Schisandra chinensis and its extracts in ruminants. The test shows that after the test sheep ate the stems and leaves of the branches of Schisandra chinensis, it can improve the vitality of adult goats in Liaoning cashmere goats, and relatively prolong the survival time of sperm.

5. Application in aquatic animals

Schisandra affects the water quality of aquaculture water. Experiments have shown that the extract of Schisandra chinensis can accelerate the metabolism of koi carp and inhibit the metabolic growth of microorganisms at a certain level, and can significantly reduce the rate of ammonia nitrogen produced by microbial metabolism in water.
