Description

Dairy cow feed added with dandelion

Technical Field

The invention relates to the field of dairy cow feed, and particularly relates to lactating dairy cow feed taking Chinese herbal medicine dandelion as an additive.

Background

With the improvement of the living standard of people, the demand of people on high-quality milk is continuously increased, and the feed is more and more emphasized as a decisive factor influencing the quality of the milk. In recent years, a large amount of antibiotics and chemical drugs are used in the breeding process, so that the quality of milk is reduced to a certain extent, and the healthy production of dairy cows is greatly influenced. In this year, a series of policies forbid the use of antibiotics are issued by the nation, and the decision of healthy production of high-quality milk is also shown. Therefore, the development of the green and environment-friendly feed capable of promoting the healthy production of the dairy cows is imperative.

At present, the milk cow breeding is mainly based on feeding of a full-mixed ration, and the milk yield of the milk cow and uncertain factors of the milk quality are improved by changing the feed formula of a pasture, so that the milk cow breeding is difficult to implement. Research shows that the Chinese herbal medicine feed additive can enhance the immunity of dairy cows and improve the milk quality and the milk yield, but most of the Chinese herbal medicine additives are mixed with a plurality of Chinese herbal medicines, the mixture ratio is complex, and although the comprehensive effect can be exerted, the Chinese herbal medicine feed additive is less applied to pastures because corresponding industries do not match in the actual production.

The influence of perilla, dried orange peel and argy wormwood leaf on the flavor, milk quality, rumen environment and blood biochemical indexes of cow's milk in the ministry of defense (2010) is informed: three medicinal and edible plants such as perilla, dried orange peel and folium artemisiae argyi are selected, and have pharmacological effects of antibiosis, anti-inflammation, antioxidation and the like. The experimental design and results are as follows: in the test, 12 Holstein cows with the same number of fetuses, good body conditions and similar weight in the lactation period are selected and divided into 3 groups, each group has 4 cows, and the design of a 4 multiplied by 4 Latin method is adopted. On the basis of feeding basic daily ration, perilla is added in group A, dried orange peel is added in group B, and folium artemisiae argyi is added in group C. Each test group was divided into 4 levels, 0, 300, 600, 900 g/day/head. The results show that: 1. the perilla frutescens can reduce the feed intake of dry substances of the dairy cows and has no obvious difference; with the increase of the addition amount of the dried orange peel and the folium artemisiae argyi, the feed intake of dry substances of the dairy cows is increased firstly and then reduced, and the difference is not obvious. 2. With the increase of the addition amount of the perilla, the tangerine peel and the folium artemisiae argyi, the milk yield of the dairy cow is increased firstly and then decreased. 3. The perilla, the dried orange peel and the folium artemisiae argyi have no obvious influence on milk fat, milk protein, lactose, total milk solid and urea nitrogen in the milk, but can obviously reduce the number of somatic cells in the milk.
