Problems solved by technology

[0003] The lack of some mineral elements in the diet of modern intensive farming mode, the high content of polyunsaturated fatty acids, the high temperature, high humidity, radiation, pathogenic microorganisms and certain chemical agents in the environment, as well as the use of a large number of drugs and vaccines, etc. Factors can induce oxidative stress in pigs, which seriously affects the economic benefits of the pig industry; at the same time, oxidative stress can seriously affect the quality of pork. Appearance; on the other hand, oxidative stress will increase the lactic acid metabolism of the pig body, which will greatly reduce the taste and nutritional value of pork

Embodiment 1

[0023] A plant extract feed additive that relieves pig oxidative stress and improves meat quality, the mangosteen bark extract is prepared by the following method:

[0024] (1) Clean the fresh mangosteen peel, dry it in an oven at 100° C. for 30 minutes, take it out and pulverize it, and pass it through a 60-mesh sieve to obtain dried mangosteen peel powder.

[0025] (2) Add mangosteen peel powder and 80% ethanol solution to the ultrasonic extraction tank at a ratio of 1:25 (g / mL) to extract for 30 minutes, filter under reduced pressure, and filter the filtrate under the condition of 3000r / min Centrifuge for 30 minutes, take the supernatant, add the filter residue to 80% ethanol solution, add it to the ultrasonic extraction tank at a ratio of 1:15 (g / mL) to extract for 40 minutes, collect and combine the two filtrates.

[0026] (3) The filtrate was concentrated, dried in vacuum and crushed through a 60-mesh sieve to obtain the mangosteen bark extract, which was used in the fol...

Embodiment 2

[0028] Application of mangosteen bark extract in the preparation of feed additives:

[0029] 1. Experimental animals and experimental design

[0030] In the experiment, 100 “Du×Chang×Da” three-way hybrid pigs with an average body weight of 30±1kg were selected and randomly divided into 5 groups, each group had 5 replicates, and each replicate had 4 pigs (male and female: half and half). Including a blank control group and 4 test groups. Add 5% oxidized fish oil to the diet of the blank control group, and add 150g / t, 200g / t, 250g / t, and 300g of mangosteen bark extract to the diet of the other four test groups on the basis of the diet of the control group. / t, respectively named: test group 1, test group 2, test group 3 and test group 4, the test period was 90 days, the pigs were free to drink water and feed during the test period, and the diarrhea, flu and mental status of the pigs were observed and recorded every day. During the feeding process, statistics were made on the i...

Embodiment 3

[0048] A plant extract feed additive for relieving pig oxidative stress and improving meat quality, including: 30 parts of grape seed extract, 40 parts of mangosteen bark extract, 15 parts of Rhodiola rosea extract, 15 parts of Schisandra fruit extract, all of which Refers to parts by weight.

[0049] The preparation method of described grape seed extract is:

[0050] (1) Clean the fresh grape seeds, dry them in an oven at 105° C. for 40 minutes, take them out and pulverize them, and pass through a 60-mesh sieve to obtain dried grape seed powder.

[0051] (2) Put the grape seed powder and 75% ethanol solution into the ultrasonic extraction tank for extraction for 30 minutes according to the ratio of material to liquid ratio of 1:25 (g / mL), filter under reduced pressure, and put the filtrate under the condition of 3000r / min Centrifuge for 30 minutes, take the supernatant, add the filter residue to the ethanol solution, and add it to the ultrasonic extraction tank at a ratio of...

Abstract

The present invention belongs to the field of feed additives and particularly discloses a plant extract feed additive for relieving porcine oxidative stress and improving meat quality and an application thereof. The applicant finds that a use of a mangosteen peel extract in the feed additive can greatly enhance antioxidant capacity of pigs, reduces acidity of pork and improves flavor quality and nutritional value of the pork. The feed additive prepared by compounding the mangosteen peel extract with a grape seed extract, a rhodiola rosea extract and a fructus schizandrae extract enables plantactive ingredients to better exert medicinal and nutritional dual effects, reduces production of lactic acid in the pig body, improves the antioxidant capacity of muscles and the liver, improves the quality of the pork, promotes promotion of immune-related functions, and has effects on relieving oxidative stress-induced adipose tissue inflammation and liver fat accumulation. Besides, the used additive is prepared from all natural plants, free of residues, toxicity and side effects, improves the growth performance of the raw pigs, and greatly improves production efficiency of pig farms.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a plant extract feed additive for alleviating pig oxidative stress and improving meat quality and its application. technical background [0002] Large-scale pig breeding plays an important role in my country's animal husbandry production. The annual pig slaughter in China accounts for 50% of the global pig slaughter, and my country's pork consumption accounts for 65% of the total meat consumption in the country. Therefore, the development of large-scale pig farming It is closely related to the development of the national economy. The "National Pig Production Development Plan (2016-2020)" report indicates that the efficiency of pig farming and feed utilization will continue to increase, while the quality of meat is also required to focus on health, without antibiotics and drug residues. [0003] The lack of some mineral elements in the diet of modern intensive farming mode, the high ...
