Problems solved by technology

In order to increase the milk production of dairy cows, nutritional additives and traditional Chinese medicine additives are usually added to dairy cows. The purpose of the addition is to provide and increase nutrition, improve digestion and immunity to promote milk production, but the degree of improvement varies greatly. , and it will lead to drug residues in the cows. After drinking milk, drug resistance and various side effects may occur, which is not good for human health.

preparation example Construction

[0024] The present invention also provides the preparation method of the feed described in the above technical solution, comprising: mixing the straw, cotton meal, soybean meal, soybean cake, salt, baking soda, molasses, Bacillus subtilis and Corynebacterium glutamicum to obtain The mixed material is adjusted to have a water content of 20-30% to obtain a fermented material, and the fermented material is fermented at 25-40° C. for 5-10 days to obtain a feed.

[0025] In the present invention, there is no special limitation on the mixing method, and conventional mixing methods can be used to mix evenly. In the present invention, the water content of the mixture is 20-30%, preferably 22-28%, more preferably 25%. In the present invention, the fermentation temperature is 25-40°C, preferably 30-35°C; the fermentation time is 5-10d, preferably 6-8d.

[0026] In the present invention, the feed for improving the milk production of dairy cows provided can be used as a common dairy cow ...

Embodiment 1

[0030] Preparation of feed to increase milk production in dairy cows:

[0031] After mixing 70 straw, 40 cottonseed meal, 35 soybean meal, 20 bean cake, 1 salt, 5 baking soda, 5 molasses, 10 Bacillus subtilis and 3 Corynebacterium glutamicum, a mixture is obtained, and the water content of the mixture is adjusted to 20 %, to obtain a fermented material, which was fermented at 25° C. for 10 days to obtain a feed.

[0032] Among them, the stalks are corn stalks with a length of 0.5 cm; the number of live bacteria of Bacillus subtilis is 1×10 12 cfu / g; the number of live bacteria of Corynebacterium glutamicum is 3×10 11 cfu / g.

Embodiment 2

[0034] Preparation of feed to increase milk production in dairy cows:

[0035] Mix 80 straw, 50 cottonseed meal, 45 soybean meal, 40 bean cake, 3 salt, 8 baking soda, 10 molasses, 15 Bacillus subtilis and 8 Corynebacterium glutamicum to obtain a mixture, and adjust the water content of the mixture to 30 %, to obtain a fermented material, which was fermented at 40° C. for 5 days to obtain a feed.

[0036] Among them, the straw is wheat straw with a length of 1.5cm; the number of live bacteria of Bacillus subtilis is 1×10 12 cfu / g; the number of live bacteria of Corynebacterium glutamicum is 3×10 11 cfu / g.

Abstract

The invention provides a feed for increasing milk yield of cows, and belongs to the technical field of cow cultivation. The feed is prepared from the following raw material components of 70-80 parts of straw, 40-50 parts of cottonseed meal, 35-45 parts of soybean meal, 20-40 parts of bean cakes, 1-3 parts of table salt, 5-8 parts of baking soda, 5-10 parts of molasses, 10-15 parts of bacillus subtilis and 3-8 parts of corynebacterium glutamicum. The feed provided by the invention is adopted, drug remaining cannot be caused, and the milk yield of the cows is also increased; after the feed provided by the invention is adopted, the daily yield of the cows can achieve 38-41kg, the milk yield of the cows in a control group is 25kg, and compared with a contrast file 1, the milk yield of the cowsfed with the feed disclosed by the invention is 13-16kg higher that of the cows in the contrast file 1, and the difference is significant.

Description

technical field [0001] The invention belongs to the technical field of dairy cow breeding, and in particular relates to a feed for improving milk production of dairy cows, a preparation method and application thereof. Background technique [0002] With the continuous improvement of people's living standards and quality of life, people's demand for milk products is increasing day by day. One of the most important factors in increasing milk production depends on what the cows are fed. In order to increase the milk production of dairy cows, nutritional additives and traditional Chinese medicine additives are usually added to dairy cows. The purpose of the addition is to provide and increase nutrition, improve digestion and immunity to promote milk production, but the degree of improvement varies greatly. , and it will lead to drug residues in the cows. After drinking milk, drug resistance and various side effects may occur, which is not good for human health. Contents of the...
