Embodiment 1

[0047] Weigh 100Kg of alfalfa powder, 20Kg of corn flour and 16Kg of water and stir at a speed of 1000r / min for 10min, then puff the mixture at 180°C to obtain 114Kg of puffed alfalfa. Mix puffed alfalfa with 342Kg water, stir at 2000r / min for 3min, add 684g amylase and 912g pectinase, and perform enzymolysis at 70°C for 3h to obtain the first enzymolysis solution. 456 g of cellulase and 45.6 g of protease were added to the first enzymatic hydrolysis solution, and the enzymatic hydrolysis was carried out at 40° C. for 10 hours to obtain the second enzymatic hydrolysis solution. The second enzymolysis solution is separated from solid and liquid, and the filtrate and filter residue are collected respectively, and the obtained filtrate is soluble dietary fiber. The soluble dietary fiber is evaporated and concentrated at 50° C., and the mass of solids in the concentrated solution obtained after concentration is preferably 60% of the total mass of the concentrated solution.

Embodiment 2

[0049] Weigh 100Kg of alfalfa powder, 40Kg of corn flour and 8Kg of water and stir at a speed of 2000r / min for 3min, then puff the mixture at 150°C to obtain 135Kg of puffed alfalfa. Mix puffed alfalfa with 675Kg water, stir at 1000r / min for 10min, add 540g amylase and 81g pectinase, and perform enzymolysis at 60°C for 5h to obtain the first enzymolysis solution. 810 g of cellulase and 40.5 g of protease were added to the first enzymolysis solution, and the enzymolysis was carried out at 50° C. for 5 hours to obtain the second enzymolysis solution. The second enzymolysis solution is separated from solid and liquid, and the filtrate and filter residue are collected respectively, and the obtained filtrate is soluble dietary fiber. The soluble dietary fiber is evaporated and concentrated at 60° C., and the mass of solids in the concentrated solution obtained after concentration is preferably 70% of the total mass of the concentrated solution.

Embodiment 3

[0052] Weigh 100Kg of alfalfa powder, 30Kg of corn flour and 12Kg of water and stir at a speed of 1500r / min for 5min, then puff the mixture at 170°C to obtain 124Kg of puffed alfalfa. Mix puffed alfalfa with 500Kg water, stir at 1500r / min for 5min, add 620g amylase and 62g pectinase, and perform enzymolysis at 65°C for 4h to obtain the first enzymolysis solution. Add 3.12Kg of cellulase and 50g of protease to the first enzymolysis solution, and perform enzymolysis at 45° C. for 8 hours to obtain the second enzymolysis solution. The second enzymolysis solution is separated from solid and liquid, and the filtrate and filter residue are collected respectively, and the obtained filtrate is soluble dietary fiber. The soluble dietary fiber is evaporated and concentrated at 55° C., and the mass of solids in the concentrated solution obtained after concentration is preferably 55% of the total mass of the concentrated solution.

Abstract

The invention provides soluble dietary fiber, lactating sow feed as well as a preparation method and application of the lactating sow feed, and belongs to the technical field of pig feed. The solubledietary fiber is prepared through the following steps: (1) preparing puffed herba medicaginis; (2) mixing the obtained puffed herba medicaginis with amylase and pectase, thus preparing first enzymatichydrolysate; (3) mixing the first enzymatic hydrolysate with cellulase and protease, thus preparing second enzymatic hydrolysate; (4) carrying out solid-liquid separation on the second enzymatic hydrolysate, and respectively collecting filtrate and filter residue, wherein the obtained filtrate is the soluble dietary fiber. The soluble dietary fiber prepared by the invention is capable of improving intestinal functions, is high in nutritive value and is easy to absorb. Further, the invention also provides the lactating sow feed comprising the soluble dietary fiber. The lactating sow feed provided by the invention has the characteristics of high nutrition, easiness in digestion, palatability and the like, and is capable of increasing the production property 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...
