Problems solved by technology

[0003] Although in the prior art, straw is also made into livestock feed, these feeds generally have the defects of poor palatability, not easily digested by livestock, and low nutritional value. When used for raising livestock, the feed intake and digestibility of livestock are very low. low, not conducive to the growth of livestock

Embodiment 1

[0025]The integrated preparation method of straw feed includes: drying the straw at a temperature of 60°C until the water content is 40%, then cutting the straw into pieces with a length of 3 cm, and placing the pieces in a cool place to spread them into pieces with a thickness of 15 cm. The first straw bed; weigh glucoamylase, hemicellulase and cellulase according to the mass ratio of 1:2:1, mix them uniformly, then add water to dissolve, and make the first mixed solution with a mass fraction of 10% , the first mixed solution is evenly sprayed on the first straw bed three times to obtain the second straw bed, wherein the weight of the first mixed solution is 25% of the weight of the straw (referring to the straw with a moisture content of 40% after drying), and the second The specific operation of spraying a mixed solution three times includes: first spraying 1 / 2 weight of the first mixed solution on the first straw bed, drying at room temperature, and then spraying 1 / 4 weight...

Embodiment 2

[0028] The integrated preparation method of straw feed includes: drying the straw in an environment with a temperature of 60°C until the water content is 40%, then cutting the straw into pieces with a length of 4cm, placing the pieces in a cool place and spreading them into pieces with a thickness of 15cm. The first straw bed; weigh glucoamylase, hemicellulase and cellulase according to the mass ratio of 1:2:1, mix them uniformly, then add water to dissolve, and make the first mixed solution with a mass fraction of 10% , the first mixed solution is evenly sprayed on the first straw bed three times to obtain the second straw bed, wherein the weight of the first mixed solution is 25% of the weight of the straw (referring to the straw with a moisture content of 40% after drying), and the second The specific operation of spraying a mixed solution three times includes: first spraying 1 / 2 weight of the first mixed solution on the first straw bed, drying at room temperature, and then ...

Embodiment 3

[0031] The integrated preparation method of straw feed includes: drying the straw in an environment with a temperature of 60°C until the water content is 40%, then cutting the straw into pieces with a length of 5 cm, and placing the pieces in a cool place to spread out the pieces with a thickness of 15 cm. The first straw bed; weigh glucoamylase, hemicellulase and cellulase according to the mass ratio of 1:2:1, mix them uniformly, then add water to dissolve, and make the first mixed solution with a mass fraction of 10% , the first mixed solution is evenly sprayed on the first straw bed three times to obtain the second straw bed, wherein the weight of the first mixed solution is 25% of the weight of the straw (referring to the straw with a moisture content of 40% after drying), and the second The specific operation of spraying a mixed solution three times includes: first spraying 1 / 2 weight of the first mixed solution on the first straw bed, drying at room temperature, and then ...

Abstract

The invention discloses an integrated preparation method for straw fodder. The integrated preparation method comprises the following steps: cutting straws into pieces, and spreading to obtain a firststraw bed; weighing glucoamylase, hemicellulase and cellulase, preparing into first mixed liquid of which the mass fraction is 10%, spraying the first mixed liquid on the first straw bed to obtain a second straw bed; weighing urea, ammonium bicarbonate, ammonium carbonate and ammonium chloride to prepare second mixed liquid of which the mass fraction is 20%, spraying the second mixed liquid on thesecond straw bed, carrying out sealing processing for 7 days, drying, and smashing into straw powder; mixing the straw powder and third mixing liquid, standing under the environment of -5 DEG C for 12h, taking out to be unfrozen, carrying out microwave radiation and rotary evaporation and concentration, and drying to obtain modified straw powder; adding a fodder additive into the modified straw powder to prepare the straw fodder. According to the integrated preparation method, the palatability of the straw fodder can be improved, the nutrition value of the straw fodder is improved, and meanwhile, the straw fodder can be more easily digested by livestock.

Description

technical field [0001] The invention relates to a preparation method of feed. More specifically, the invention relates to an integrated preparation method of straw feed, which belongs to the technical field of feed preparation methods. Background technique [0002] Straw is the general term for the stems, leaves and spikes of mature crops. In agriculture, it generally refers to the remaining part of the harvested seeds of corn, wheat, rice and other crops after they mature. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matter and other nutrients, and can be used as roughage for livestock, especially corn straw, wheat straw and rice straw. However, at present, except a small amount of straw is used for feeding livestock and some of it is used for composting, most of it is directly burned as fuel. The burning of a large amount of straw will not only pollute the environment, but also a great waste of biological resources. Making straw into feed...
