Embodiment 1
[0055] refer to figure 1 , a Caragana mechanically fermented full mixed feed and a preparation method thereof, comprising:
[0056] A caragana mechanically fermented full mixed feed, comprising the following components in terms of mass percentage: 23% Caragana, 8% Hubing, 1.5% premix, 6% soybean meal, 31% corn, 3% bitter bean dregs, licorice 0.6%, urea 0.4%, bran 10.5%, sudan grass 16%;
[0057] It is a biological feed made by finely pulverizing caragana bar → high temperature disinfection → aerobic fermentation → nutritional formula → anaerobic fermentation.
[0058] Wherein, in the high-temperature disinfection step, the temperature is controlled at 75°C-80°C, and the duration is 2-2.5 hours;
[0059] In the aerobic fermentation step, add aerobic fermentation strains and stir evenly, supply oxygen and control the temperature at 50°C-60°C, and the fermentation time is 6-24 hours;
[0060] In the anaerobic fermentation step, add anaerobic fermentation strains and stir evenl...
Embodiment 2
[0063] The difference between this embodiment and embodiment 1 is:
[0064] A caragana mechanically fermented full mixed feed, the mass percent of each component is: Caragana 20%, Hubing 9%, premix 1%, soybean meal 7%, corn 32%, licorice 0.5%, urea 0.5% %, Bran 10%, Sudan Grass 20%.
Embodiment 3
[0066] The difference between this embodiment and embodiment 1 is:
[0067] A caragana mechanically fermented full mixed feed, the mass percentage of each component is: Caragana 25%, Hubing 6%, premix 2%, soybean meal 5%, corn 30%, bitter bean dregs 5%, licorice 0.7%, urea 0.3%, bran 11%, sudan grass 15%.

Abstract
The invention discloses caragana microphylla mechanical fermentation type full-mixed feed and a preparation method thereof. The caragana microphylla mechanical fermentation type full-mixed feed is prepared from the following components in percentage by mass: 20 to 25 percent of caragana microphylla, 6 to 9 percent of rape seed cakes, 1 to 2 percent of premix, 5 to 7 percent of soybean meal, 30 to 32 percent of corn, 0 to 5 percent of bitter bean dregs, 0.5 to 0.7 percent of liquorice root, 0.3 to 0.5 percent of urea, 10 to 11 percent of bran and 15 to 20 percent of sudangrass. The preparation method comprises the following steps of: rubbing and crushing, high-temperature disinfection, aerobic fermentation, nutrition formulation and anaerobic fermentation. According to the caragana microphylla mechanical fermentation type full-mixed feed and the preparation method thereof, a mechanical fermentation method can be adopted, and mechanical production can be realized; and by adopting combination of aerobic fermentation and anaerobic fermentation, the prepared fermentation type full-mixed feed is high in nutritional quality and easy to digest and absorb.
Description
technical field [0001] The invention relates to the field of feed processing, in particular to a caragana mechanically fermented full mixed feed and a preparation method thereof. Background technique [0002] Caragana, as an excellent windbreak and sand-fixing shrub, has the characteristics of strong ecological adaptability, well-developed root system, strong water absorption, and strong stress resistance. However, with the increase of stand age, stand aging and biomass decline will generally occur in Caragana forest , stand aging and other phenomena, its economic and ecological benefits continue to decline. In order to give full play to the ecological and economic benefits of windbreak and sand fixation, soil and water conservation, etc. of Caragana forest, and to achieve the resource utilization of Caragana forest, it is particularly important to carry out reasonable stubble and rejuvenation. The problem of utilization of agricultural and forestry wastes produced after st...
