Method for manufacturing biologically-fermented straw nutrition forage grass at low temperature for beef

Abstract

The invention discloses a method for manufacturing biologically-fermented straw nutrition forage grass at low temperature for beeves. The method comprises the steps of taking crop maize straw as raw materials, taking a mixed fungus culture of small filamentous fungi, bacillus subtilis, candida utilis, streptococcus faecalis and pediococcus acidilactici as a leavening agent, adding non-protein nitrogen to prepare a biological fermentation conditioner, uniformly spraying the biological fermentation conditioner on base straw forage grass materials in a layering mode, controlling the humidity between 50% and 55%, packaging resultants, and fermenting the resultant at 10 DEG C-20 DEG C for 7-10 days to obtain the biologically-fermented straw nutrition forage grass. By adopting the method, the biologically-fermented forage grass for fattening beeves is easy to manufacture in the natural environmental condition of the north, and can meet the requirements of favorable quality, favorable palatability and easiness for digestion.

Description

technical field [0001] The content of the invention belongs to the technical field of making edible forage grass for herbivores, and relates to a corn stalk bio-fermentation forage suitable for beef cattle fattening. Background technique [0002] In the cattle industry, the breeding of beef cattle occupies an increasingly important position. With the continuous improvement of people's living standards, the diet structure is also changing rapidly, and the market demand for beef cattle is increasing day by day. [0003] The northern region of my country is an ideal area for beef cattle breeding from geographical conditions to climatic conditions. A large number of agricultural straw resources provide a rich material basis for the breeding and development of beef cattle. These favorable conditions will contribute to the high return of beef cattle breeding in the north. [0004] But in production practice, the beef cattle breeding method in our country basically follows the tr...

Problems solved by technology

[0006] However, various straw fermented forage grasses known in the art have relatively unstable effects, difficult homogenization of quality, great influence of climatic conditions, poor operability and many other practical problems to be solved.

In particular, the nutrient content of the straw itself is low, and the straw fermented forage produced by conventional methods has a large moisture content (65-75%) and less dry matter, which is not suitable for the growth and development of beef cattle and affects the fattening effect of beef cattle

In northern my country, the temperature changes rapidly after corn harvesting, the period suitable for straw forage processing is short, that is, it enters the pre-cold season, and the time for spring warming is still late, and the climate conditions limit the processing and modulation of straw forage grass to a large extent. and feeding
