Problems solved by technology

[0003] Oat grass is a kind of annual high-quality gramineous grass, which has the characteristics of high yield, high sugar content and good palatability. The crude protein (CP), crude fat (EE) and neutral detergent fiber (NDF) of oat green hay The contents of acid detergent fiber (ADF) and acid detergent fiber (ADF) are 13.29%, 2.61%, 58.54%, and 30.23%, all of which are suitable for feeding dairy cows. It caused problems such as high cost and shortage of forage grass in winter and spring, which affected the development of large-scale dairy cow breeding

Embodiment 1

[0023] This example relates to a milk cow feed component that can replace oat grass—forage millet hay and its preparation.

[0024] Preparation: Dry the fresh forage grasses of forage millet harvested from the grouting stage to the milk maturity stage by flattening the stalk drying method, that is, use stone rollers to crush and flatten the fresh forage grass stalks on the cement floor, or use pasture stalks After the fracturing machine crushes and flattens the stems, spread them into grass ridges or grass strips, and then dry them in the sun and dry them naturally in a sunny day (the best daytime temperature range is 19°C to 31°C). , until the water content of aspartate grass drops below about 15%, and the whole plant is green, fragrant, leaves do not fall off or fall off very little, the stems, leaves and ears can be eaten by livestock, and the texture is soft and palatable. Millet is green hay, and the protein, fat, fiber, minerals, amino acids and other nutrients of fresh ...

Embodiment 2

[0047] This example relates to the influence of the preparation conditions of forage millet hay in Example 1 on the product quality.

Embodiment 21

[0049] This example relates to the effect of cutting at different growth stages on the quality of forage millet obtained.

[0050] The preparation of high-quality and high-yield forage millet hay should be based on the nutrition and feed value of the mowed forage millet, and at the same time take into account the biological yield, hay forage value, and water content or dry-to-fresh ratio (dry-to-fresh ratio = hay quality / fresh grass quality) and other indicators; therefore, the quality and yield of forage millet have an important relationship with its growth period. The number of days from emergence to maturity of forage millet is called the growth period of forage millet. The growth period of forage millet is affected by the variety and sowing date. The growth period of forage millet sown in spring is generally about 115 days; The growth period of millet is generally about 90 days; when the millet is sown in autumn idle fields, it generally cannot mature normally, but it ca...

Abstract

The invention discloses an ingredient constituent capable of substituting for oat grass in milk cow feed. The ingredient constituent is feeding millet green hay with whole green plants which is prepared from fresh millet straw of feeding millet mowed from a grain formation stage to a milky-ripe stage through pressing stalks flat and performing drying in a natural airing way instead of manual tedding. The obtained feeding millet green hay is suitable for feeding milk cows in the aspect of each nutrient indicator, does not cause unwell emergency reaction of the milk cows, has no negative effects, can promote the lactation yield increase of the milk cows, also can significantly improve the milk calcium level of milk and is the ideal milk cow-feed ingredient constituent substituting for the oat grass. The feeding millet green hay provided by the invention has a simple preparation method and low cost and can be widely used as the milk cow feed. The milk cow feed prepared from the feeding millet green hay can produce remarkable economic benefits in the aspects of reducing feed cost, increasing the lactation yield of the milk cows, improving milk quality, etc. and has positive promotion significance.

Description

technical field [0001] The invention relates to the technical field of dairy cow feed, in particular to a raw material component that can replace oat grass in dairy cow feed, a preparation method of the raw material component, and a dairy cow feed composed of the raw material component. Background technique [0002] As the output of animal husbandry increases year by year, consumers have higher and higher requirements for product quality. For large-scale animal husbandry, the quality of feed directly determines the quality of aquaculture products. The production of ruminants occupies a relatively large proportion in the animal husbandry industry. The so-called ruminants refer to animals that have the phenomenon of ruminating the half-digested food in the stomach after a period of time after eating and chewing again. After ruminants eat roughage, Most of them are swallowed into the rumen without being fully chewed. After soaking and softening in the rumen for a period of time...
