Beef cattle daily ration taking mushroom residues as raw material and preparation method and applications thereof

Abstract

The invention discloses a beef cattle daily ration taking mushroom residues as the raw material and a preparation method and applications thereof, and belongs to the technical field of beef cattle breeding. The daily ration is prepared from the following components in parts by weight: 25 to 35 parts of fermented mushroom residue, 20 to 25 parts of silage corn, 10 to 15 parts of crop straw, and 30 to 40 parts of fine fodder; wherein the fermented mushroom residue is prepared by mixing mushroom residues with corn flour according to a weight ratio of 100:4-5 and adding a fermentation composite bacterium liquid to carry out enclosed fermentation for 20 to 30 days; the fermentation composite bacterium liquid accounts for 1.5 to 2.5% of the weight of fermentation raw materials, and is composed of bacillus subtilis, lactobacillus plantarum, and candida utilis according to a bacterial colony ratio of 2-4: 4-5: 3-4; 0.5 to 2 wt% of cane sugar solution is added into the abovementioned bacteria to prepare the fermentation composite bacterium liquid, and for each liter of the fermentation composite bacterium liquid, the total active bacterium number is not less than 500 billion. The circulation utilization of mushroom residues is realized, the wastes are converted into valuable resources, moreover, the prepared mushroom residue has a good taste and is palatable, the cost is reduced, and the benefit is increased.

Description

technical field [0001] The invention belongs to the technical field of beef cattle breeding, and in particular relates to a beef cattle ration using shiitake mushroom chaff as a raw material and a preparation method and application thereof. Background technique [0002] As the country pays more and more attention to environmental protection, clean production, harmless waste disposal and recycling have become the inevitable requirements for sustainable agricultural development. In terms of edible fungus production, a large amount of edible fungus cultivation waste is produced in my country every year. Except for a small amount of these fungus chaff resources that are further processed and utilized, most of them are still discarded and incinerated at will, which not only occupies land, wastes resources, but also brings mold pollution. and pests, causing serious pollution to the environment. At the same time, during the production of edible fungi, a large amount of lignin and c...

Problems solved by technology

[0003] Because there is still a certain amount of wood fiber in the fungus chaff, the texture is rough, the palatability is poor, and it also contains nutrients such as mycelium and protein, which are easily spoiled and deteriorated. It is not suitable for direct use as feed raw materials and must be properly treated.

The existing fungus chaff feed technology mainly includes physical method, chemical method and biological fermentation method, among which the physical method cannot eliminate the contamination of bacteria, and the processed fungus chaff has poor palatability and low digestibility; the chemical method also has poor palatability problems; biological fermentation can further degrade crude fiber, improve flavor and palatability, and increase nutritional value, which has a good application prospect

[0004] In terms of the feed technology of shiitake mushroom chaff, there are few studies on biological fermentation methods, lack of technologies such as fermentation microorganism selection, fermentation process, and feed formulation, and the produced feed has low nutritional value and poor palatability
