Problems solved by technology

[0003] In order to solve the unsatisfactory effect of preventing and treating swine fever by inoculating pig PRRS vaccine in recent years, the purpose of the present invention is to provide a feed that can improve the PRRS antibody level of piglets. Using the feed of the present invention during the growth period of piglets can significantly improve the piglets' PRRS antibody levels. Level to level, the effect of preventing PRRS in pigs during the whole growth period is better

Embodiment 1

[0010] A feed for improving the PRRS antibody level of piglets, the feed is composed of basal feed and Gardenia jasmine extract, and the weight ratio of basal feed and Gardenia jasmine extract is 100:0.85;

[0011] The basic feed is composed of the following raw materials in weight percentage: 54% puffed corn, 22% puffed soybean meal, 19% bran, 3% fishmeal, and the balance is 4% Beinongkangdi concentrated premix for pigs;

[0012] The preparation method of the Gardenia jasmine extract is as follows: crush the Gardenia jasminoides, pass through a 40-mesh standard sieve, add 85% ethanol according to the ratio of material to liquid 1:6-1:8, adjust the Ph to 5.5, and pass it into the extraction tank. Extract at 45° C. for 2 hours, recover ethanol, and spray dry to obtain Gardenia jasmine extract.

[0013] The present invention is described below in conjunction with specific comparative test:

[0014] The test pigs were selected from 30 Landrace piglets with a weight of 25-30 kg, ...

Embodiment 2

[0020] A feed for improving the PRRS antibody level of piglets, the feed is composed of basal feed and jasmine jasmine extract, and the weight ratio of basal feed and jasmine jasmine extract is 100:0.86;

[0021] The basic feed is composed of the following raw materials in weight percentage: 54% puffed corn, 22% puffed soybean meal, 19% bran, 3% fishmeal, and the balance is 4% Beinongkangdi concentrated premix for pigs;

[0022] The preparation method of the gardenia jasmine extract is as follows: crush the gardenia jasminoides, pass through a 40-mesh standard sieve, add 87% ethanol according to the ratio of solid to liquid 1:6-1:8, adjust the Ph to 5.5, and pass it into the extraction tank. Extract at 48° C. for 2.1 hours, recover ethanol, and spray dry to obtain Gardenia jasmine extract.

[0023] The present invention is described below in conjunction with specific comparative test:

Abstract

The invention relates to a feed, in particular to a feed for improving PRRS (porcine reproductive and respiratory syndrome) antibody level of piglets. The feed is composed of basic feed and gardenia florida extract, wherein the weight ratio of the basic feed and the gardenia florida extract is 100:0.85-0.88. The feed for improving the PRRS antibody level of the piglets facilitates generation of PRRS antibodies well in bodies of the piglets by adding the gardenia florida extract in basic rations of the piglets, and plays an important role in preventing pig blue ear disease in production practice, and experiments verify that the feed does not have side effects for the piglets, and is safe and effective.

Description

technical field [0001] The invention relates to a feed, in particular to a feed for improving the PRRS antibody level of piglets. Background technique [0002] PRRS--Porcine Reproductive and Respiratory Syndrome (commonly known as PRRS) This disease is characterized by reproductive disorders (abortion, stillbirth, mummified fetus) of pregnant sows and respiratory diseases of pigs of various ages, especially piglets. One of the main diseases in large-scale pig farms. At present, intensive pig farms have implemented comprehensive prevention and control measures based on vaccination of PRRS vaccine for the control of pig PRRS. PRRS vaccine has played a role in the prevention and treatment of pig PRRS. To the decisive role, but in recent years the immune effect is not ideal. The phenomenon of immune failure also occurred in the application of tissue culture attenuated vaccine. Contents of the invention [0003] In order to solve the unsatisfactory effect of preventing and tr...
