Vegetable soybean hull silage and preparation method thereof

Abstract

The invention discloses vegetable soybean hull silage and a preparation method thereof. The vegetable soybean hull silage comprises the following raw materials in percentage by weight: 10-30% of dry corncob with particle size of 5-10mm, 5% of sweet potato skin, 0.05-0.75% of lactic acid bacteria, 0.1-1.5% of urea, 0.55-4.25% of dry corncob with the particle size of 3-5mm, and the balance of processed fresh green soybean hull. The preparation method comprises the following steps of: (1) uniformly mixing the lactic acid bacteria, urea and dry corncob with the particle size of 3-5mm according toa ratio, so as to prepare a feed additive; and (2) mixing the dry corncob with the particle size of 5-10mm, sweet potato skin and processed fresh green soybean hull with the feed additive according to a ratio, and placing the mixed raw material into a silage pit and compacting layer by layer until density reaches up to 550-600g / L; and carrying out silage fermentation at the temperature of 20-30 DEG C for 60-90 days. The vegetable soybean hull silage disclosed by the invention has acid flavour, soft texture and good palatability; and dry material content and other nutritional components of thesilage are improved, the vegetable soybean hull silage disclosed by the invention can hardly go bad and can be stored for a long time, and production cost is low.

Description

technical field [0001] The invention relates to silage for animal husbandry, in particular to a pod shell silage mainly composed of pod shells of vegetable soybeans (commonly known as edamame), a by-product of food processing, and a preparation method thereof. Background technique [0002] In the traditional dairy farming system, the conventional roughage is mainly silage corn, soybean meal and pasture such as alfalfa and ryegrass. With the rapid development of animal husbandry production, the price of conventional roughage for dairy cows continues to rise, labor costs are also increasing, the cost of dairy cow breeding is getting higher and higher, and the gap between the supply and demand of dairy cow conventional feed is getting bigger and bigger, which cannot meet the needs of the production and development of dairy farming. Therefore, dairy farming enterprises have to seek to develop new feed resources to replace or supplement the lack of conventional feed for dairy cow...

AI Technical Summary

Problems solved by technology

At present, most of the edamame varieties in Anhui Province are spring soybeans and summer soybeans, and there is a lack of autumn soybeans. In particular, summer soybeans are concentrated in the market. Because the water content of fresh pod shells after processing is as high as 70%, and there are some seeds, the crude protein content Rich, perishable and rotten, difficult to store; if squeezed or dried, its nutrient content will be reduced and the production cost will be too high; drying requires a huge site and is easy to be polluted

All this has limited the use of fresh pod shells as feed for grass-fed livestock
