Problems solved by technology

[0004] In the above technical scheme, when the Eucommia leaves are dried at 40°C-60°C, if the humidity is high, they are prone to fermentation and deterioration; while drying at 150°C-200°C will cause some biologically active components and Nutrient failure
Although the extraction method at 65°C-80°C is suitable for the temperature, the process is complex and the extraction cost is high, and about 50% of the active ingredients in Eucommia leaves cannot be extracted, and are wasted with the residue, reducing the effective ingredients of Eucommia leaves Utilization of

Embodiment 1

[0027] (1) Put the collected fresh eucommia leaves, alfalfa leaves and purple pearl leaves that are not eroded by diseases and insect pests into a vacuum drying oven with a temperature of 60 ° C ~ 80 ° C and a stirring device inside for vacuum drying, so that the water content reaches 12% ~ 15%;

[0028] (2) The dried Eucommia leaves, alfalfa leaves and Zizhu leaves are respectively crushed with a pulverizer to a fineness of less than 0.5 mm.

[0029] (3) The pulverized Eucommia leaves, alfalfa leaves and purple pearl leaves powders are weighed and mixed evenly according to the mass fraction of 60:20:20.

[0030] (4) The above-mentioned uniformly mixed feed additives are vacuum-packed, and when used, they are mixed according to the ratio of feed additives to 5% of the mass percentage of commercially available common feeds, and are suitable for feeding pregnant sows.

Embodiment 2

[0032] (1) Put the collected fresh eucommia leaves, alfalfa leaves and purple pearl leaves that are not eroded by diseases and insect pests into a vacuum drying oven with a temperature of 60 ° C ~ 80 ° C and a stirring device inside for vacuum drying, so that the water content reaches 12% ~ 15%;

[0033] (2) The dried Eucommia leaves, alfalfa leaves and Zizhu leaves are respectively crushed with a pulverizer to a fineness of less than 0.5 mm.

[0034] (3) The pulverized Eucommia leaves, alfalfa leaves and purple pearl leaves powders are weighed and mixed evenly according to the mass fraction of 75:20:5.

[0035] (4) The above-mentioned uniformly mixed feed additives are vacuum-packed, and when used, they are mixed according to the ratio of feed additives to 6% of the mass percentage of commercially available common feeds, and are suitable for feeding lactating sows and piglets.

Embodiment 3

[0037] (1) Put the collected fresh eucommia leaves, alfalfa leaves and purple pearl leaves that are not eroded by diseases and insect pests into a vacuum drying oven with a temperature of 60 ° C ~ 80 ° C and a stirring device inside for vacuum drying, so that the water content reaches 12% ~ 15%;

[0038] (2) The dried Eucommia leaves, alfalfa leaves and Zizhu leaves are respectively crushed with a pulverizer to a fineness of less than 0.5 mm.

[0039] (3) The pulverized Eucommia leaves, alfalfa leaves and purple pearl leaves powders are weighed and mixed evenly according to the mass fraction of 8:10:5.

[0040] (4) The uniformly mixed feed additive is vacuum-packed and mixed according to the ratio of feed additive to 3% of the mass percentage of commercially available common feed when used, and is suitable for feeding fattening pigs.

Abstract

The invention relates to the technical field of a feed additive and particularly relates to a compound type pig feed additive as well as preparation and application methods thereof. The compound type pig feed additive is formed by the following components in parts by weight: 50-85 parts of eucommia ulmoides leaf powder, 10-30 parts of alfalfa leaf powder and 5-20 parts of folium callicarpae pedunculalae leaf powder. The compound type pig feed additive is prepared by taking fresh eucommia ulmoides leaves, alfalfa leaves and folium callicarpae pedunculalae leaves, which are not corroded by plant diseases and insect pests as raw materials, crushing the leaves into powder of being less than 0.5 mm after drying the leaves in vacuum, and mixing according to the mass ratios. The feed additive has the advantages that the immunity of live pigs is effectively improved, the growth of the live pigs is accelerated and the meat quality is improved.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and relates to a multifunctional compound feed additive for pigs prepared by compounding powders of leaves of Eucommia ulmoides, leaves of alfalfa and leaves of purple pearl and methods for preparing and using the same. Background technique [0002] Since the use of some chemical synthetic drugs such as antibiotics can increase the daily weight gain and lean meat percentage of pigs, the phenomenon of abuse of antibiotics or other synthetic drugs in feed is quite common. "Clenbuterol" problem not only restricts the development of my country's pig breeding industry, but also arouses great concern in the world, especially developed countries such as Europe and the United States. Many countries in the world have successively banned or restricted the application of antibiotics in feed. Therefore, it has become a research hotspot to find a natural feed additive that has the function of antibiot...
