Embodiment 1

[0035] Embodiment 1, the preparation of feed additive

[0036] Take 9 parts by weight of galactomannooligosaccharide and 1 part by weight of ligustalactone A, and mix them to prepare a feed additive S1 with a weight ratio of 9:1 between galactomannan-oligosaccharide and listonin A.

[0037] Take 5 parts by weight of galactomannooligosaccharide and 5 parts by weight of ligustalactone A, and mix them to prepare a feed additive S2 with a weight ratio of 1:1 between galactomannan-oligosaccharide and lisantrolactone A.

[0038] Take 8 parts by weight of galactomannooligosaccharide and 2 parts by weight of ligustalactone A, and mix them to prepare a feed additive S3 with a weight ratio of 4:1 between galactomannooligosaccharide and lisantrolactone A.

Embodiment 2

[0039] Embodiment 2, the application of the feed additive of the present invention in regulating the intestinal flora of weaned piglets

[0040] 1. Experimental animals and grouping treatment

[0041] Choose 120 weaned piglets of Duroc × (Landrace × Large White) three-way hybridization 28 days old, all boars castrated, according to body weight, sex, consanguineous principle, be divided into 6 groups immediately, promptly the composition group 1-3 of the present invention (implementation) Feed additives S1-S3) prepared in Example 1, galactomannan oligosaccharide group, ligustonin A group and control group, 20 piglets in each group. In the diet of S1-S3 composition group, galactomannan oligosaccharide group, and Ligustilide A group, add the above-mentioned feed additive according to 1% of the total weight of the feed (the total weight of the active ingredients added by each group is the same), the The diet was pig feed of the same weight without adding the above-mentioned feed ...

Abstract

The present invention relates to a feed additive for adjusting intestinal flora of piglets, wherein a weight ratio of active ingredients of galactomannan oligosaccharide to senkyunolide A is (10:1)-(1:10). Compared with common feed additives, the feed additive is simple n preparation method, reasonable in compatibility and remarkable in curative effects, and can significantly improve the intestinal flora of the piglets. Due to the fact that the additive is free of western medicine ingredients, the feed additive is free of toxic and side effects and drug resistance.

Description

technical field [0001] The invention relates to the field of feed, in particular to a feed additive for piglets. Background technique [0002] Since the discovery of the growth-promoting effect of antibiotics on animals in the middle of the 20th century, antibiotics have been widely used as feed additives in the aquaculture industry; in view of the negative effects of antibiotics and people’s growing concern about food health, many countries have enacted laws to ban antibiotics. and the laws and regulations on the use of chemically synthesized drugs. In recent years, research on the development of safe, non-toxic, and side-effect-free alternatives to antibiotics has begun. [0003] Studies have confirmed that fructooligosaccharides can improve the production performance and disease resistance of pigs, chickens, cattle and other animals; mannan oligosaccharides can improve the production performance of mice, pigs, chickens, cattle, aquatic animals and other animals and promo...
