Problems solved by technology

However, in corn production, a large amount of corn cobs and corn husks are wasted and even become polluted
At the same time, when the corn is dry, it not only consumes a lot of energy, but also reduces the digestibility of starch and protein, and destroys some vitamins.

Embodiment 1

[0020] Use a crushing and beating machine to crush and beat 100kg of fresh corn cobs with coating, the length of the coating and corn cobs is 700-800 mm, and the fineness of corn kernels is 250-300 mm to obtain corn kernels, coatings and corn cobs 100kg of mixed pulp. Mix 4kg of clean water, 1kg of molasses, 0.15kg of cellulase, 0.05kg of xylanase, 0.05kg of pectinase, 0.5kg of lactic acid bacteria seed liquid, 0.15kg of Bacillus subtilis seed liquid, and 0.10kg of Saccharomyces cerevisiae seed liquid Mix to prepare 6kg of fermented liquid. After fully mixing 100kg of mixed pulp, 6kg of fermented liquid and 10kg of bran, bury and compact them under natural temperature and pH conditions (that is, what is the pH value and temperature after mixing, then what is the pH value and temperature during silage) , not artificially changed) to ferment and enzymatically hydrolyze to obtain enzymatically hydrolyzed corn silage.

Embodiment 2

[0022] Use a crushing and beating machine to crush and beat 500 kg of fresh corn cobs with coating, the length of the coating and corn cob is 800-1000 mm, and the fineness of corn kernels is 300-400 mm to obtain corn kernels, coating and corn cob 500kg of mixed pulp. Clean water 15kg, molasses 8kg, cellulase 0.3kg, xylanase 0.1kg, pectinase 0.1kg, lactic acid bacteria seed liquid 1.0kg, Bacillus subtilis seed liquid 0.25kg, Saccharomyces cerevisiae seed liquid 0.25kg Mix to prepare 25kg of fermented liquid. After fully mixing 500kg of mixed pulp, 25kg of fermented liquid and 50kg of bran, they are buried and compacted, fermented and enzymatically hydrolyzed under natural temperature and pH conditions, and enzymatically hydrolyzed corn silage is obtained.

Embodiment 3

[0024] Use a crushing and beating machine to crush and beat 1000kg of fresh corn cobs with coating, the length of the coating and corn cobs is 500-600 mm, and the fineness of corn kernels is 150-250 mm to obtain corn kernels, coatings and corn cobs 1000kg of mixed pulp. Clean water 20kg, molasses 20kg, cellulase 0.5kg, xylanase 0.2kg, pectinase 0.2kg, lactic acid bacteria seed liquid 1.2kg, Bacillus subtilis seed liquid 0.3kg, Saccharomyces cerevisiae seed liquid 0.5kg Mix to make 42kg of fermented liquid. After fully mixing 1000kg of mixed pulp, 42kg of fermented solution and 80kg of bran, they are buried and compacted, fermented and enzymatically hydrolyzed under natural temperature and pH conditions to obtain enzymolyzed corn silage.

Abstract

The invention belongs to the technical field of fermentation of a feed, enzyme and microorganisms, and particularly relates to a method for preparing special enzymolysis corn silage for sows. The method comprises the following steps: crushing and pulping the coated corns to prepare corn mixed slurry containing corn kernels, coatings and corncobs; mixing water, honey, cellulose, xylanase, pectinase with mixed bacteria liquid to prepare enzymatic hydrolysate; evenly mixing, then heaping and compacting the corn mixed slurry, the enzymatic hydrolysate and the bran; carrying out anaerobic fermentation and enzymolysis, so as to prepare the enzymolysis corn silage. The enzymolysis corn silage prepared by the method contains soluble polysaccharide, lactic acid, small peptide, amino acid, vitamin and probiotics, has the characteristics of being abundant and balanced in amino acid, high in nutrient, easy to digest, good in palatability and the like, the sow lactation quantity can be obviously improved, the feed intake is obviously increased, and the sow constipation is significantly reduced.

Description

technical field [0001] The invention belongs to the technical field of feed, enzyme preparation and microbial fermentation, and in particular relates to a preparation method of special enzymolysis corn silage for sows. Background technique [0002] China is a country with a large population and the largest pig raising country in the world. In 2013, the output value of China's animal husbandry industry reached 2.7 trillion yuan, and 719 million pigs were slaughtered, including 52 million sows and 50.53 million tons of pork. According to statistics from the Ministry of Agriculture, the total output of commercial feed in my country will reach 191 million tons in 2013, including 162 million tons of compound feed; 23 million tons of concentrated feed; 6.3 million tons of additive premixed feed. Ton. It is estimated that by 2015, the national compound feed output will reach more than 200 million tons, of which sow feed will reach more than 8 million tons. [0003] As we all know...
