Embodiment 1

[0027] (1) The dairy cow feed additive is composed of the following mass ratios: 60 parts of seaweed, 30 parts of cockscomb inflorescence, 3 parts of honeysuckle, 5 parts of Tongcao, 4 parts of gentian, 8 parts of dandelion, and 5 parts of purslane.

[0028] (2) Select 20 black-and-white dairy cows in the pre-lactating period 5±2 days after calving in the first parity as experimental cows. The initial milk production of the experimental cows is similar. The 20 dairy cows are randomly divided into experimental group and control group. Each group 5 repetitions.

[0029] (3) Under the same feeding and management conditions, the experimental dairy cows were fed intensively in the troughs of the same area in the barn respectively, and the same basic ration was provided for the experimental dairy cows. The basic feed formula composition: concentrate (corn 45.0%, wheat Bran 20.0%, bean cake 13.0%, cottonseed cake 13.0%, etc.) 8.0kg, alfalfa 4.5kg, brewer's grains 10.0kg, silage corn ...

Embodiment 2

[0035] (1) The dairy cow feed additive is composed of the following mass ratios: 80 parts of seaweed, 40 parts of cockscomb inflorescence, 6 parts of honeysuckle slag, 10 parts of Tongcao, 6 parts of gentian, 10 parts of dandelion, and 10 parts of purslane.

[0036] (2) Select 20 black-and-white dairy cows in the peak lactation period with similar milk yield after the second parity calving 20 days as the experimental cows, and divide the 20 cows into the experimental group and the control group randomly, with 5 replicates in each group.

[0037] (3) Under the same feeding and management conditions, the experimental dairy cows were fed separately in the troughs of the same area in the cowshed, and the same basic feed was provided for the experimental dairy cows. The basic feed formula composition: concentrate (corn 45.0%, wheat bran 20.0%, bean cake 13.0%, cottonseed cake 13.0%, etc.) 8.0kg, alfalfa 6.0kg, brewer's grains 6.0kg, silage corn 16.0kg. Feeding 3 times a day, milkin...

Embodiment 3

[0043] (1) The dairy cow feed additive is composed of the following mass ratios: 70 parts of seaweed, 35 parts of cockscomb inflorescence, 4.5 parts of honeysuckle, 7 parts of Tongcao, 5 parts of gentian, 9 parts of dandelion, and 8 parts of purslane.

[0044] (2) In summer, 20 middle-lactating black-and-white dairy cows with 160 days of second parity lactation and similar milk yield were selected as experimental cows, and the 20 cows were randomly divided into 3 test groups and control groups, 5 in each group repeat.

[0045] (3) Under the same feeding and management conditions, the experimental dairy cows were fed separately in the troughs of the same area in the barn, and the same basic feed was provided for the experimental dairy cows. The basic feed formula consisted of refined grains (corn 45.0%, wheat bran 20.0%, bean cake 20.0%, cottonseed cake 10.0%, etc.) 10.0kg, alfalfa 4.5kg, brewer's grains 10.0kg, silage corn 14.0kg. Feeding 3 times a day, milking time is 6 am a...

Abstract

The invention relates to the field of breeding, and particularly discloses a cow feed additive and a preparation method thereof. The cow feed additive disclosed by the invention comprises the following components of seaweed, cockscomb inflorescences, honeysuckles, medulla tetrapanacis, radix gentianae, herba taraxaci and purslane herbs. When 2.0-7.0% of the cow feed additive is added to a conventional feed, the milk producing performance of cows can be obviously improved, and increasing of the milk producing quantity of the cows, the milk protein rate and the milk fat rate is facilitated; in addition, raw materials of the cow feed additive disclosed by the invention have the advantages of being rich in sources, low in price, simple in processing, safe, free from toxic and side effects and the like, and the cow feed additive has a practical application value and a practical popularization value for the breeding industry and the production of high-quality milk.

Description

technical field [0001] The invention relates to a feed additive, in particular to a dairy cow feed additive mainly composed of seaweed powder and cockscomb powder and supplemented by various Chinese herbal medicine powders. Background technique [0002] Chinese black-and-white cows are the breed of dairy cows with the highest milk production, the largest number, and the widest distribution in China. The healthy milk production of black-and-white cows is directly related to the milk source of Chinese people. Affected by the external environment, feed, etc., dairy cows have poor lactation stability, and both milk production and milk quality will be affected. First of all, dairy cow feed is often composed of relatively simple coarse material and concentrated material, lacking high-quality and rich dietary nutrition, such as rich amino acids, vitamins, dietary fiber, mineral elements, trace elements, etc., which reduces the appetite and digestion ability of dairy cows And diarr...
