Embodiment 1

[0048] Take by weighing sweet potato vine powder 100Kg, glucose 3Kg, nutrient salt 0.5Kg, water 200Kg and lactic acid bacteria (the live bacteria concentration of lactic acid bacteria is 1.0 * 10 6 CFU / g) 10Kg was stirred at 2000r / min for 3min, and then the mixture was anaerobically fermented at 25°C for 24h to obtain a lactic acid bacteria fermentation broth. Mix the obtained lactic acid bacteria fermentation broth with citric acid (the mass ratio of sweet potato vine powder and citric acid is 20:1), obtain the citric acid mixed solution, adjust the pH value to 7, mix it with Aspergillus niger, and ferment it at 28°C for 72h to obtain Aspergillus niger fermentation broth. Mix the obtained Aspergillus niger fermentation liquid with cellulase, pectinase and protease in a mass ratio of 100:0.1:0.05:0.005, carry out enzymolysis at 35°C for 12 hours, filter, collect the filtrate and filter residue respectively, and obtain the filtrate For soluble dietary fiber.

Abstract

The present invention provides a soluble dietary fiber, a lactating sow feed, and a preparation method and applications of the lactating sow feed, and belongs to the technical field of pig feeds. Thesoluble dietary fiber is prepared by the following steps: 1) preparing lactic acid bacterium fermentation liquor; 2) preparing a citric acid mixed solution; 3) fermenting the obtained citric acid mixed solution by aspergillus niger to obtain aspergillus niger fermentation liquor; 4) mixing the aspergillus niger fermentation liquor with cellulase, pectinase and protease to obtain an enzymolysis liquid; and 5) filtering the enzymolysis liquid, and respectively collecting a filtrate and filter residues, wherein the obtained filtrate is the soluble dietary fiber. The soluble dietary fiber preparedby the method can improve intestinal functions, has high nutritive value, and is easy to absorb. Further, the present invention also provides a lactating sow feed comprising the soluble dietary fiber, and the feed has the characteristics of being high in nutrient content, easy to digest and good in palatability, and can improve the production performance of sows.

Description

technical field [0001] The invention belongs to the field of pig feed technology, and in particular relates to a soluble dietary fiber, a feed for sucking sows and a preparation method and application thereof. Background technique [0002] China is the world's largest pig raising country. In 2017, the output value of China's animal husbandry industry reached 3.6 trillion yuan, and 689 million pigs were slaughtered, including 42 million sows. In pig production, the phenomenon of constipation in sows is relatively common. It is a stubborn problem that plagues the majority of pig producers in production management. According to statistics, about 40% to 60% of sows have constipation. Sows with long-term constipation will lead to prolonged delivery and even dystocia. In severe cases, elevated body temperature will be accompanied by diseases, stillbirths, and agalactia syndrome. [0003] Fiber is known as the seventh largest nutrient besides the six major nutrients of protein, fa...
