[0046] In order to better realize the present invention, preferably, on the basis of the above formula, the grains are young grains expanded by airtight fermentation.

[0047] In order to better realize the present invention, preferably, on the basis of the above formula, the temperature of the airtight fermentation is 27°C-32°C, the pressure is 1.20*105pa-1.33*105pa, and the fermentation time is 4-8 days.

[0048] In order to better realize the present invention, preferably, on the basis of the above formula, the crude fiber green material is one or more of cut or crushed sweet potato vines, ryegrass, purple cabbage, green grass and corn leaves mixture.

[0049] In order to better realize the present invention, preferably, on the basis of the above formula, the Chinese herbal medicine adjuvant is a powdered mixture of sun-dried Polygonum argyi, Artemisia argyi, Angelica dahurica, Atractylodes atractylodes and Tsaoguo, and the water content is less than 10%.

Embodiment 3

[0051] The present invention also provides a method for preparing pig feed mixed with crude fiber, which specifically includes the following steps:

[0052] Step S100, weighing straw biological feed, bran, bean cake, rapeseed meal, grape pomace, Salix leaves and grains, and recording to obtain weight data M1;

[0053] In step S200, the straw biological feed, bran, bean cake, rapeseed meal, grape pomace, Salix leaves and grains weighed in step S100 are placed in the sun or placed in a dryer for drying, according to Light intensity and time determine the drying cycle, and then weigh again to obtain weight data M2; calculate N1=(M1-M2) / M1*100%; when N1 is greater than 40%, proceed to the next step; when N1 is less than 40%, repeat Steps S100-S200;

[0054] Step S300, put the dried straw bio-feed, bran, bean cake, rapeseed meal, grape pomace, Salix leaves and grains obtained in step S200 into a pulverizer for crushing to obtain a powdered straw bio-feed , bran, bean cake, rapese...

Abstract

The invention discloses a preparation method of coarse fiber mixed pig feed. The preparation method is characterized by specifically comprising the following steps: step S100, weighing straw biological feed, bran, soybean cakes, rapeseed meal, grape pomace, salix psammophila leaves and cereal grains, and performing recording to obtain weight data M1; step S200, drying the straw biological feed, the bran, the soybean cakes, the rapeseed meal, the grape pomace, the salix psammophila leaves and the cereal grains weighed in the step S100 under exposure to the sun or in a drying machine; step S300,pulverizing the dried straw biological feed obtained in the step S200; step S400, preparing fresh sweet potato vines into block green feed with the maximum size smaller than or equal to 2 centimeters; and step S500, thoroughly mixing the straw biological feed, the bran, the soybean cakes, the rapeseed meal, the grape pomace, the salix psammophila leaves and a corn flour mixture obtained in the step S300 with the green feed blocks obtained in the step S400, and adding trace elements.

Description

technical field [0001] The invention relates to the field of pig feed, in particular to green mixed feed for domesticated pigs, in particular to a method for preparing pig feed mixed with crude fiber. Background technique [0002] Feed is very important for raising livestock. It can not only meet the nutritional elements needed by livestock, but also promote rapid growth, shorten the feeding cycle of livestock and reach the edible conditions as soon as possible. Therefore, since the appearance of feed, people have abandoned the traditional use of fresh green plants or grain as the main or even all food source for livestock; more or less industrial feed is used for feeding. For example, the most common pig feed is prepared into pellet feed by extruding technology, which has the advantages of convenient transportation, storage and feeding. [0003] Pig feed is usually the feed for raising domestic pigs composed of protein feed, energy feed, roughage, green feed, silage, miner...
