Embodiment 1

[0025] A kind of alfalfa silage for dairy cows, which comprises the following components and raw materials by weight: 20-40 parts of alfalfa, 60-200 parts of ryegrass, 5-10 parts of sweet sorghum straw, 5-20 parts of hawthorn, and astragalus polysaccharide 2-4 parts, lactic acid bacteria preparation 4.0mg / kg-7.0mg / kg.

[0026] Optionally, the alfalfa silage for dairy cows also includes the following raw materials in parts by weight: 7-10 parts of ginseng stems and leaves, and 1-2 parts of licorice extract.

[0027] The alfalfa silage for dairy cows provided by the application prevents rumen inflation caused by frequent consumption of dairy cows by adding hawthorn powder, and improves the palatability of the alfalfa silage feed by adding sweet sorghum stalks and astragalus polysaccharides. In addition, the alfalfa silage for dairy cows provided by the application has a simple preparation process, reduces the pH value of the silage, increases the content of lactic acid and water...

Embodiment 2

[0029] A kind of alfalfa silage for dairy cows, comprising the following components and raw materials by weight: 30 parts of alfalfa, 70 parts of ryegrass, 8 parts of sweet sorghum straw, 10 parts of hawthorn, 3 parts of astragalus polysaccharide, and 6.0 mg / kg of lactic acid bacteria preparation .

[0030] Optionally, the alfalfa silage for cows also includes 8 parts of ginseng stems and leaves and 1 part of licorice extract.

Embodiment 3

[0032] A kind of alfalfa silage for dairy cows, comprising the following components and raw materials by weight: 40 parts of alfalfa, 200 parts of ryegrass, 6 parts of sweet sorghum straw, 8 parts of hawthorn, 2 parts of astragalus polysaccharide, and 5.0 mg / kg of lactic acid bacteria preparation .

[0033] Optionally, the alfalfa silage for dairy cows also includes 7 parts of ginseng stems and leaves and 2 parts of licorice extract.

Abstract

The invention relates to the technical field of dairy cow feed processing, in particular to alfalfa silage for dairy cows and a preparation method thereof. The alfalfa silage comprises, by weight, 20-40 parts of alfalfa, 60-200 parts of lolium perenne, 5-10 parts of sweet sorghum straw, 5-20 parts of fructus crataegi, 2-4 parts of astragalus polysaccharide and 4.0-7.0mg/kg of lactobacillus preparation. Rumen swelling of dairy cows caused by frequent eating of the alfalfa silage is prevented by adding hawthorn powder, and palatability of the alfalfa silage is improved by adding the sweet sorghum straw and astragalus polysaccharide. The preparation method is simple in preparation process, pH value of the silage is lowered, content of lactic acid and water-soluble carbohydrate is increased, ensiling quality of alfalfa is improved obviously, and the preparation method is an effective way to solve the problem that fresh forage grass lacks in winter during livestock production and is of important significance in reasonably utilizing alfalfa.

Description

technical field [0001] The application relates to the technical field of dairy cow feed processing, in particular to an alfalfa silage for dairy cows and a preparation method thereof. Background technique [0002] Silage is a kind of feed, which is made of plant feed with high moisture content after sealing and fermenting, and is mainly used to feed ruminants. Silage is more resistant to storage than fresh feed, and its nutritional content is stronger than dry feed. Plus, silage storage takes up less land and has no fire problems. [0003] Silage is a kind of roughage obtained by chopping green feed with a moisture content of 65%-75%, and inhibiting the reproduction of various bacteria through the fermentation of anaerobic lactic acid bacteria under airtight and hypoxic conditions. . Silage has a sour and fragrant smell, is soft and juicy, has good palatability, is rich in nutrition, and is good for long-term preservation. [0004] Alfalfa is a high-quality perennial leg...
