Problems solved by technology

Therefore, during the fermentation process, it is difficult for lactic acid bacteria to quickly form a dominant flora and cannot reduce the pH value in a short time
The results: First, all kinds of bacteria are growing and multiplying, causing the temperature to rise rapidly, resulting in the extension of the pre-fermentation period
The second is that during the preparatory fermentation process, the silage will lose a lot of nutrients and energy due to heat, and also cause a pungent smell and poor palatability.
The third is the massive reproduction of mold and spoilage bacteria during the fermentation process, resulting in partial mildew and rot in the silage, especially the top, bottom and edge mildew and rot.
Fourth, due to the existence of a large number of miscellaneous bacteria, it is easy to ...

Embodiment 1

[0073] A method for preparing fermented concentrate silage special for sows, the steps are as follows:

[0074] ①. Preparation of silage:

[0075] Dry the fresh alfalfa to a moisture content of 40-50%. 500kg of fresh alfalfa with a water content of 40-50% was chopped and broken to 1cm by a crushing beater to obtain 500kg of fresh alfalfa powder. 100kg of carrots with a moisture content of 80-85% are crushed and beaten to obtain 100kg of carrot pulp.

[0076] 500kg of fresh alfalfa powder and 100kg of carrot pulp are mixed to make 600kg of silage raw materials with a moisture content of about 75%. Insert 10kg of lactic acid bacteria seed liquid and mix in 60g of compound enzyme (40g of cellulase, 8g of xylanase, 8g of pectinase and 4g of mannanase in the compound enzyme), fill and compact in the silo, and naturally enzymatically and After 15 days of anaerobic fermentation, 595 kg of silage was obtained.

[0077] ②. Preparation of fermented concentrate wet base:

[0078] Af...

Embodiment 2

[0084] A method for preparing fermented concentrate silage special for sows, the steps are as follows:

[0085] ①. Preparation of silage:

[0086] The fresh silage corn stalks are air-dried to a moisture content of 65-75%. Using a crushing beater, 1000 kg of fresh silage corn stalks with a water content of 65-75% are chopped and crushed to 1 cm to obtain 1000 kg of fresh silage corn stalk powder.

[0087] Inject 10kg of lactic acid bacteria seed solution and mix 30g of compound enzyme (20g of cellulase, 4g of xylanase, 4g of pectinase and 2g of mannanase in compound enzyme) into 1000kg of fresh silage corn stalk powder, pack and compact in In the silo, after 15 days of natural enzymatic hydrolysis and anaerobic fermentation, 995kg of silage was obtained.

[0088] ②. Preparation of fermented concentrate wet base:

[0089] After mixing 100kg of clean water, 100kg of soybean meal, 50kg of corn gluten powder, 50kg of rice bran, and 20kg of molasses syrup, insert 30kg of lactic ...

Embodiment 3

[0095] A method for preparing fermented concentrate silage special for sows, the steps are as follows:

[0096] ①. Preparation of silage:

[0097] Dry the alfalfa to a moisture content of 50-60%. Using a crushing beater, 1000 kg of fresh silage corn stalks with a moisture content of 50-60% are chopped and crushed to 1 cm to obtain 1000 kg of fresh silage corn stalk powder.

[0098] Insert 20kg of lactic acid bacteria seed solution into 1000kg of fresh silage corn stalk powder, mix with 30g of compound enzyme (20g of cellulase, 4g of xylanase, 4g of pectinase and 2g of mannanase in the compound enzyme), pack and compact In the silo, after natural enzymatic hydrolysis and anaerobic fermentation for 15 days, 1110kg of silage was obtained.

[0099] ②. Preparation of fermented concentrate wet base:

[0100] After mixing 100kg of clean water, 100kg of soybean meal, 50kg of DDGS, 50kg of bran, and 20kg of molasses syrup, insert 20kg of lactic acid bacteria seed liquid and mix in 5...

Abstract

The invention belongs to the technical fields of feeds, enzyme preparations and microbial fermentation, and particularly relates to a preparation method of zymohydrolysis concentrated silage special for sows. The preparation method comprises the following steps of cutting short fresh pasturage or tuberous roots and stems, performing mashing, inoculating lactic acid bacteria, and performing natural enzymolysis and anaerobic fermentation so as to obtain silage; mixing one or more of cake meal, food processing by-products and cereals, with clean water and molasses syrup, inoculating lactic acid bacterium liquid, and performing natural enzymolysis and anaerobic fermentation so as to obtain fermented concentrated wet basis; and inoculating oxygen consumption fermentation bacterium liquid into a concentrated silage fermented substrate, and performing natural oxygen consumption fermentation so as to obtain the zymohydrolysis concentrated silage special for sows. The zymohydrolysis concentrated silage is rich in fermented cellulose lactic acid, calcium lactate, small peptide, amino acid, vitamins and probiotics, has the characteristics of being high in nutrition, easy to digest, good in palatability and the like, and can obviously increase the lactation quantity of the sows, obviously increase the food consumption and notably reduce the constipation of the sows.

Description

technical field [0001] The invention belongs to the technical field of feed, enzyme preparation and microbial fermentation, and in particular relates to a method for preparing fermented concentrate silage special for sows. Background technique [0002] China is a country with a large population and the largest pig raising country in the world. In 2015, the output value of China's animal husbandry industry reached 3.5 trillion yuan, 643 million pigs were slaughtered, of which 45 million sows were on hand, and pork output was 54.87 million tons. According to statistics from the Ministry of Agriculture, the national commercial feed production reached 218 million tons in 2015. Among them, 179 million tons of full-price feed, 21.51 million tons of concentrated feed, 6.4 million tons of premixed feed, including 89.74 million tons of pig feed, 90 million tons of poultry feed, 53 million tons of aquatic feed, and 8.5 million tons of cattle and sheep feed, 3.5 million tons of feed ...
