Preparation method of high-protein and low-fiber biological nutrition maize straw forage grass

Abstract

The invention discloses a preparation method of high-protein and low-fiber biological nutrition maize straw forage grass. In the production process of the preparation method, two parts, namely comprehensive mechanical processing and biological modulation are accomplished together. The preparation method comprises the following steps of: crushing maize straw, winnowing the crushed maize straw to take hulls and leaves, and carrying out microbial fermentation on the crushed maize straw to obtain high-quality straw forage grass. Compared with the unprocessed maize straw, the processed and modulated forage grass has the advantages of obviously enhancing the total nutrient content, enhancing the crude protein by 40% and reducing low fibers by about 30%, and has the advantages of favorable palatability, high nutritive value and favorable feeding effect. Moreover, the preparation method is suitable for large-scale and specialized production.

Description

technical field [0001] The content of the invention belongs to the technical field of production of forage grass for livestock feeding, and relates to a straw microbial fermented forage grass suitable for feeding ruminant livestock such as cattle and sheep. Background technique [0002] The rapid development of my country's modern animal husbandry is taking the road of ecological grain-saving animal husbandry. The practical problems faced by the forage industry are the shortage of green fodder and the low utilization rate of roughage. This has become the main limiting factor seriously hindering the development of my country's animal husbandry. [0003] In production practice, due to the limited natural forage and planted high-quality green fodder, it is far from meeting the development needs of animal husbandry. In my country's current herbivorous livestock such as cattle and sheep, 80% of the roughage depends on agricultural straw resources to supplement. Due to the poor ...

Problems solved by technology

[0003] In production practice, due to the limited natural pasture and planted high-quality green fodder, it is far from meeting the development needs of animal husbandry. At present, in the breeding of grass-fed livestock such as cattle and sheep in my country, 80% of the roughage needs to be supplemented by agricultural straw resources.

Due to the poor quality of straw, it has many lignin and crude fiber components, low protein and carbohydrate content, hard texture, poor palatability, and low digestibility, which seriously affects the feed intake and digestion and absorption of livestock.
