Problems solved by technology

[0004] Artificially cultivating Cordyceps militaris with rice and pupa powder is a new technology developed in recent years. After the fruiting body is harvested, the culture medium residue covered with mycelium is discarded as waste, resulting in serious waste of resources and environmental pollution.

Embodiment 1

[0026] A method for preparing chicken feed from steam-exploded Cordyceps militaris medium residue, comprising the steps of:

[0027] 1) Cut the residue of Cordyceps militaris culture medium into flakes, soak in tap water to make the final water content 40-60%; 2) Then add the flake Cordyceps militaris obtained in step 1) to the steam explosion reactor Culture medium residues are blasted under a pressure of 1 MPa, and the pressure holding time is 5 minutes; after the blasting is completed, quickly open the ball valve at the bottom of the reactor to take out the material and dry it naturally; 3) 30 kg of the blasted material obtained in step 3) , 15kg of water peanuts, 12kg of mulberry leaves, 40kg of corn flour, 1kg of wheat bran, and 2kg of soybean meal are mixed and ground into 20-40 mesh fine powder; 4) adding biological enzymes, including 0.2kg of hemicellulase and 0.20kg of cellulase, Protease 0.28kg, amylase 0.32kg, glucoamylase 0.25kg. Use HCl or NaOH to adjust its pH v...

Embodiment 2

[0028] Embodiment 2: the preparation method of embodiment 2 is the same as that of embodiment 1, the only difference is that step 2) the pressure of the steam explosion reactor is 0.5MPa, and the material, water peanuts, mulberry leaves and starch raw materials after the explosion in step 3) The proportioning is the following parts by weight: blasted material 25kg; water peanut 10kg; mulberry leaf 10kg; starch raw material 40kg. Among them, corn flour:wheat bran:soybean meal in the starch raw material is mixed according to the weight ratio of 40:1:2. In step 4), 0.14 kg of hemicellulase, 0.16 kg of cellulase, 0.20 kg of protease, 0.30 kg of amylase, and 0.20 kg of glucoamylase.

Embodiment 3

[0029] Embodiment 3: the preparation method of embodiment 3 is the same as that of embodiment 1, the only difference is that step 2) the pressure of the steam explosion reactor is 1.5MPa, and the material, water peanuts, mulberry leaves and starchy raw materials after the explosion in step 3) The proportioning ratio is the following parts by weight: 45 kg of blasted material; 20 kg of water peanuts; 15 kg of mulberry leaves; 45 parts of starch raw materials. Among them, corn flour:wheat bran:soybean meal in the starch raw material is mixed according to the weight ratio of 40:1:2. In step 4), 0.30 kg of hemicellulase, 0.25 kg of cellulase, 0.35 kg of protease, 0.35 kg of amylase, and 0.30 kg of glucoamylase.

[0030] Chicken feed of the present invention and the contrast of existing chicken feed:

[0031] Choose 600 chickens, control group (adopting existing feed) raises 50 chickens, repeats 3 times, totally 150; Test group (respectively adopts the chicken feed that the embodi...

Abstract

The invention belongs to the field of feed development and specifically relates to a method of preparing chicken feed by performing steam explosion on cordyceps medium residues. The method includes the following steps: (1) cutting the cordyceps medium residues into slices; (2) adding the sliced cordyceps medium residues obtained in the step (1) into a steam explosion reactor, performing explosionat a pressure of 0.5-1.5MPa and performing pressure holding for 5min; (3) mixing the exploded materials obtained in the step (2) with alternanthera philoxeroides, mulberries and starch-type ingredients and performing grinding into powder of 20-40 mesh; (4) adding biological enzymes into the powder, regulating the pH value to 6.5-8.0 and performing complete mixing and stirring for 20-43h; and (5) after stirring uniformly, taking out the mixture and performing drying, grinding and granulating. The formula of the chicken feed provided by the invention improves egg quality, reduces the breakage rate of eggshell, also relieves the heat stress reaction of chicken and increases egg production.

Description

technical field [0001] The invention belongs to the field of feed development, and in particular relates to a method for preparing chicken feed by steam explosion culture medium residue of Cordyceps militaris. Background technique [0002] With the improvement of people's living standards, people's demand for eggs and quality requirements also increase thereupon. Feed is an important factor affecting the quality of eggs. On the one hand, the research and development of most chicken feeds now mainly focus on the production speed and egg production rate of chickens, while ignoring the improvement of their quality. On the other hand, the proportion of corn, wheat, soybean meal, etc. in the traditional feed formula is relatively high. With the increasing price of food, the cost of feed is getting higher and higher, which seriously affects the economic benefits of poultry farming. [0003] Cordyceps militaris [Cordyceps militaris (L.) Link], belonging to the phylum Fungi, Ascomy...
