Problems solved by technology

Because it cannot be compacted, there is too much air remaining in the straw, which causes aerobic bacteria to multiply and makes the feed moldy and rotten; during the feeding process, air invades the cellar, causing a new round of mildew
The total loss of traditional silage is as high as 30%, and due to the musty smell in the feed, it will seriously affect the feed intake of dairy cows

Embodiment Construction

[0016] (1), timely harvest. Harvest when there are more than four green leaves in the sorghum ripening period to ensure that the nutritional content of the feed and the moisture content of the straw are 60%. When harvesting the sorghum straw, the length is 2 to 4 cm to prevent straw pollution.

[0017] (2), straw rubbing. Use a kneader to finish. The 9RC-3 rubbing machine is used to longitudinally flatten and rub the sorghum stalks and cut and rub them to destroy the cuticle and stem nodes on the surface of the straw. bundles to reduce the probability of puncturing plastic bags.

[0018] (3), spray additives. For example, Baokangsheng silage agent, which contains cellulase, xylanase, and glucose oxidizing mold, can decompose crude fiber, especially effectively degrade NDF and ADF, improve the palatability and digestibility of feed, and increase the yield of dairy cows. Food intake and speed, milk production increased significantly.

[0019] (4), pressing and baling. The ...

Abstract

The invention discloses a preparation method of animal feed added with sorghum straw. The preparation method includes following steps: harvesting the straw, rubbing the straw, spraying an additive, press-baling, bagging and sealing, stacking, and externally packaging. The sorghum straw feed is high in palatability, intake rate can reach higher than 90%, the defect that conventional sorghum straw ensiling technology causes mildewing and rotting and low in palatability is overcome, and yield and quality of the ensiled sorghum straw feed are improved; ecological returning of the sorghum straw tothe field is facilitated, and environment pollution is reduced; product added value of crops is increased, breeding feed cost is lowered, and increase of both planting benefit and breeding benefit isrealized.

Description

technical field [0001] The invention relates to a preparation method of animal feed added with sorghum stalks. Background technique [0002] Sorghum straw is an important biological resource that can be transformed and utilized in various forms. However, in recent years, with the transformation of farming methods and lifestyles, the effect of returning sorghum stalks to the field is not satisfactory, which has led to repeated bans on farmers burning sorghum stalks. Sorghum straw burning is very serious, which seriously pollutes the environment and directly affects traffic safety and residents' lives. It is imperative to ban sorghum straw burning. [0003] Sorghum straw silage has many advantages: less nutrient loss, generally no more than 10%, tender and juicy stems and leaves, rich in digestible vitamins, protein, fat and other nutrients, sweet and sour smell, high digestibility, good palatability, and can promote Appetite, promote digestion, can be fed in all seasons. B...
