Embodiment 1

[0023] Embodiment 1. The preparation method of corn stalk feed.

[0024] The preparation method of the corn stalk feed described in the present embodiment specifically comprises the following steps:

[0025] (1) Air-dry the harvested stalks and bundle them into 3m 3 ;

[0026] (2) irradiating the baled stalks for 3 hours at a dose of 1400 kGy with gamma rays from an irradiation processing device (source strength 50,000 curies);

[0027] (3) cutting the irradiated stalk to a 3cm long stalk;

[0028] (4) preparation medium, the medium composition is the glucose that the mass fraction is 5%, the NaCl that the mass fraction is 13% and the water that the mass fraction is 82%, pass total ammonia water to adjust pH to 5, 120 degree autoclave sterilization. The strain concentration was 1×10 8 cfu / ml yeast and lactic acid bacteria are mixed with the culture medium according to the mass ratio of 1:1:40, and fermented in a sealed container at 30°C for 5 days to obtain a starter;

Abstract

The invention discloses a preparation method of straw feed, and belongs to the technical field of feed fermentation. In order to solve the problem of complex process for preparing ruminant animal feedfrom straw, the invention provides a preparation method of straw feed, which comprises the following steps: irradiating straw for 1-3h under the dosage of 1000-1400kGy of gamma rays; and further fermenting the irradiated straws by using saccharomycetes and lactic acid bacteria. The preparation method of the straw feed is simple in process, the digestibility of ruminants to straw can be improved,and the fermentation capacity of rumen can be promoted.

Description

technical field [0001] The invention belongs to the technical field of feed fermentation, and in particular relates to a method for preparing straw feed. Background technique [0002] The output of straw is huge and widely distributed, and the main component of its organic matter is cellulosic carbohydrates, which is a very valuable biomass energy resource in agricultural ecosystems. Due to the tight connection between cellulose and hemicellulose inside the straw, it is difficult to be digested and utilized by ruminants. Therefore, a large amount of straw is burned, which not only causes environmental pollution, but also causes a waste of resources. [0003] Ruminants have a large demand for roughage. Choosing high-quality and cheap feed to replace traditional conventional feed materials can improve the economic benefits of farming. Therefore, improving the utilization rate of ruminants to straw has broad prospects. At present, there are many ways to treat straw to improve ...
