Embodiment 1

[0035] In this example, Schisandra chinensis is placed in an oven at 65°C and dried to constant weight, processed and crushed into fine powder, passed through a 40-mesh sieve to make the original powder of Schisandra chinensis, and extracted with alcohol (8 times the amount of 80% ethanol reflux extraction, 2h times), It is 0.354% to measure its schisandrin A content with high performance liquid chromatography, and the schisandrin B content is 0.664%, and concrete chromatographic condition is chromatographic column (C 18 Symmetry); mobile phase: methanol-water (75:25); flow rate: 1.0ml / min; detection wavelength: 254nm; column temperature: 25°C; injection volume: 10μl. Add it to the diet of broiler chickens, laying hens, laying hens, heat-stressed laying hens and weaned piglets at a ratio of 0.1% to 0.3%.

[0036]It has been proved by experiments that the addition of schisandra alcohol extract to each group in this example has no significant effect on the activity of superoxide...

Embodiment 2

[0052] The basic process of this embodiment is the same as that of Embodiment 1, the difference lies in the use of CO 2 Supercritical extraction, that is, using supercritical CO at 30MPa and 45°C 2 Extraction 2.5h, supercritical CO 2 The extraction equipment adopts HA221-40-48SFE device, Jiangsu Nantong Huaan Supercritical Extraction Co., Ltd., and finally obtains a yellow viscous liquid extract with a yield of 12.5%. In this embodiment, Schisandra supercritical CO 2 The extract is added to livestock and poultry feed as a feed additive at a ratio of 0.1% to 0.4%. Experiments have shown that at the age of 35 days, adding 0.2%, 0.4% Schisandra supercritical CO 2 The extract group can significantly improve the total antioxidant capacity of broiler kidney. At the age of 56 days, Schisandra supercritical CO 2 The extract can significantly improve the total antioxidant capacity of the heart (see Table 14).

Abstract

The invention provides an application method for taking magnolia vine fruit as a feedstuff additive. The method comprises the following steps: baking the magnolia vine fruit into a baking oven at the temperature of 60 to 70 DEG C till reaching constant weight; processing and crushing the magnolia vine fruit into fine powder; screening the fine powder through a 40-mesh sieve to prepare magnolia vine fruit initial powder; obtaining yellow sticky liquid extract through extraction; and adding the extract serving as the feedstuff additive into the feedstuff for beasts and birds in a proportion of 0.1 to 0.4 percent. The product which has natural oxidation resisting activity can be applied to the ration of pigs and chicken as the feedstuff additive. The feedstuff additive is capable of effectively removing excessive lipid peroxides in an organism, improving the activity of the antioxidase in the organism, improving the lipid stability of the organism, promoting the immunity of the organism, and improving the internal environment of the intestinal tract. In addition, the feedstuff additive can also remarkably improve the productivity of heat stress laying chicken and the lipid stability of the immunity.

Description

(1) Technical field [0001] The invention belongs to the application field of agriculture, animal husbandry and veterinary medicine, and specifically relates to a feed additive technology. (2) Background technology [0002] The use of Chinese herbal medicines as feed additives has a long history of thousands of years in my country. For example, the earliest medical book "Shen Nong Cao Mu Jing" in my country has the record of "feeding pigs with tung leaves, three times the fat, and easy to raise". Chinese herbal feed additives are based on the theory of traditional Chinese medicine in my country, scientifically formulated and compatible, not only have the effects of strengthening the body and eliminating pathogens, invigorating the spleen and appetizing, antibacterial and growth promotion, enhancing animal immune function, improving the quality of animal products, etc., but also have a wide range of sources, no toxic side effects, and no residues , no drug resistance, has arous...
