Background
The pennisetum hydridum is a perennial plant of pennisetum genus of Gramineae family, and is called as pennisetum hydridum because its stem is similar to bamboo. The plant height is 2.5-3.5 m, the plant has 12-16 knots, the stem is 2-4 cm thick, the leaf length is about 160 cm, and the leaf width is 3-6 cm. The stem and leaf after drying contains crude protein 14.33%, crude fat 3.33%, crude fiber 33.64%, nitrogen-free extract 33.85%, and each hectare corresponds to the protein content of 8-10 hectare corn, so the stem and leaf is nutritious. The leaves of the bamboo-wood composite plant are soft, crisp and tender, have good palatability, can replace bamboo-wood frames, and can grow well in the south of China, in the Henan, in the Hebei and other places. Especially, the root system of the product is developed, the root length can reach more than 3 meters, a fibrous root network can be formed in a short time, moisture and soil can be firmly locked, and the product is an ideal plant for preventing water and soil loss and treating the barren beach steep slope and river levee.
The pennisetum hydridum is used as a high-quality pasture, contains a plurality of necessary nutrients required by livestock and poultry, and can be used with little or no additive so as to save cost. The pennisetum hydridum is not easy to age, not easy to be fibrillated and high in yield, so that grains can be greatly saved and the cultivation cost can be reduced when the pennisetum hydridum is used for cultivating the pennisetum hydridum, and the pennisetum hydridum has wide prospect in the field of pasture and livestock cultivation.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a method for processing wangcao.
In order to achieve the above object, the present invention provides the following solutions:
a method for processing wangcao, comprising the following steps:
s1: harvesting the prince grass mechanically, crushing the prince grass by a crusher, then introducing a water press to press out 35-55% of water, introducing a pulverizer, and sieving to obtain powder; sieving to obtain powder with particle size of 1-5 mm;
s2: placing the powder into a stirrer, adding the bacteria and enzymes to cooperatively ferment the composition, and mixing to obtain a mixture;
s3: placing the obtained mixture into a fermentation tank for fermentation, keeping the height of the mixture at 50-80cm in the tank body for normal fermentation, automatically turning the stack in the fermentation tank at the temperature of the mixture being higher than 40 ℃ during normal fermentation, ventilating and cooling, performing normal fermentation for 24-30h, performing anaerobic fermentation for 18-30h, and performing secondary normal fermentation for 24-48h after anaerobic fermentation; finally granulating to obtain a finished feed product;
the synergistic fermentation composition of the bacterial enzymes takes 100 parts of added weight per 100 parts of fermented wangcao as a unit, and comprises the following components: 0.5 part of mixed microbial inoculum, 0.6 part of compound enzyme, 10 parts of corn fiber, 5 parts of cane molasses, 10 parts of sargentgloryvine stem and 7 parts of peanut bran; the mixed microbial inoculum is prepared by mixing lactobacillus acidophilus, bacillus amyloliquefaciens, bacillus subtilis and saccharomycetes according to the mass ratio of 1.7-2.5:0.5-1.3:1.8-2.1:2-3.5; the complex enzyme is prepared by mixing phytase, mannanase, protease, cellulase and saccharifying enzyme according to the mass ratio of 1-2:0.1-0.4:1-1.7:3-5:1.9-2.6;
in the step S3, anaerobic fermentation is carried out for 26 hours at the temperature of 27-38 ℃ and secondary normal fermentation is carried out for 36 hours.
Preferably, the mixed microbial inoculum is prepared by mixing lactobacillus acidophilus, bacillus amyloliquefaciens, bacillus subtilis and saccharomycetes according to a mass ratio of 2.1:0.9:2:2.8.
The beneficial effects of the invention are as follows:
1. as can be seen from Table 1, the feed prepared in example 3 is the most preferred example. The daily average daily gain of the feed is improved by 6.6% compared with that of the feed of the comparative example 4, the feed conversion ratio is improved by 8.4%, the cost of the feed per unit weight is reduced by 5.6%, the secondary normal fermentation is favorable for the cellulose and lignin in the wang grass to be fully degraded, the microbial inoculum can be fully contacted with the wang grass fiber, the fermentation activity is promoted, the synthesis amount of mycoprotein and volatile fatty acid is increased, the nutritional value and the digestibility of the feed are improved, and the effect of the feed can be more obvious when the feed is used in large and medium pig farms.
