Problems solved by technology

[0007] Aiming at the current use of premixed feed plus other raw materials to make sow feed, the available fiber raw materials are single, especially the feed that is mainly bran has high levels of toxins, resulting in many disadvantages. The inventor has conducted in-depth research and clarified According to the acceptance criteria of bagasse and poplar wood, and according to the characteristics of the fiber composition of bagasse and poplar wood, the corresponding lye soaking and steam explosion treatment were carried out respectively, so as to obtain the semi-finished products of bagasse and poplar wood fiber

preparation example Construction

[0041] The preparation method of the invention comprises the following steps: processing two kinds of fiber raw materials, sugarcane bagasse and poplar, to obtain corresponding fiber semi-finished products, then mixing the two fiber semi-finished products in a certain proportion, granulating, and crushing to obtain irregular flake particles. In the production process of premixed feed for pig farms, due to the light specific gravity of powdered raw materials and the large volume of materials, there is a lot of dust when mixing the ingredients, and it is prone to stratification, resulting in uneven mixing. Therefore, it is necessary to further compress and granulate the powdered fiber with low specific gravity to ensure the convenience of the pig farm's ingredients and the uniformity of the feed. A detailed description will be given below.

[0043] In step (1) of the present invention, bagasse raw materials and wood raw materials are collected, wherein the ra...

Embodiment 1

[0060] The present embodiment is the preparation method of functional fiber and its application on sow, and the specific method is as follows:

[0061] 1. Processing of bagasse

[0062] (1) Alkali treatment: The bagasse is mixed with a 2% mass fraction of sodium hydroxide solution (99% purity) in a weight: volume ratio of 1:2, the temperature of the solution is 30°C, and the soaking time is 2 hours , and then soaked in tap water with a temperature of 30 ° C for 1 hour, and then washed.

[0063] (2) Steam flash explosion: put the bagasse into the flash chamber through the feeding barrel, increase the pressure of the flash chamber to 2MPa through the pressurizing valve, and then blast for 1min. , The elevator is used for grinding to a ball mill pulverizer, and the crushing particle size is more than 90% and passes through a 20-mesh sieve to obtain a semi-finished product of bagasse fiber.

[0064] 2. Treatment of poplar

Embodiment 2

[0085] The present embodiment is a preparation method of functional fiber and its application on sows, and the specific method is as follows:

[0086] 1. Processing of bagasse

[0087] (1) Alkali treatment: The bagasse is mixed with a 3% mass fraction of sodium hydroxide solution (99% purity) in a weight: volume ratio of 1:3, the temperature of the solution is 40°C, and the soaking time is 2 hours , and then soaked in tap water with a temperature of 40 ° C for 1 hour, and then washed.

[0088] (2) Steam flash explosion: put the bagasse into the flash chamber through the feeding barrel, increase the pressure of the flash chamber to 2MPa through the pressurizing valve, and then blast for 1min. , Elevator to ball mill pulverizer for pulverization, and the pulverization particle size is more than 90% and passes through a 20-mesh sieve.

[0089] 2. Treatment of poplar

[0090] (1) Primary powder of trees: peel the trees, wash with tap water, and then enter the poplar into the wo...

Abstract

The invention discloses a functional dietary fiber used in cooperation with a premixed feed and a preparation method of the functional dietary fiber. The functional fiber comprises a modified bagasse raw material and a modified wood raw material which are compounded. The functional dietary fiber can effectively replace bran to be used in pregnancy feed and lactation feed, and the content of vomitoxin in the feed is remarkably reduced, so that adverse consequences of toxins on sows are reduced, and the production performance of the sows is improved. Besides, the functional fiber can obviously improve constipation of the sows and improve satiety of the sows, and has a wide market application prospect in sow feed as a functional fiber raw material.

Description

technical field [0001] The invention relates to the field of feed, in particular to a functional dietary fiber used with premixed feed and a preparation method thereof. Background technique [0002] Sows are usually restricted during gestation to control the size of the pregnant sow and prevent problems such as dystocia due to excess weight. However, excessive feed restriction embarrassing sow starvation, and sows exhibiting abnormal behaviors during pregnancy such as empty chewing, biting, frequent standing and lying down, all negatively impact sow reproductive performance. Dietary fiber is low cost and an effective way to keep sows properly satiety. Therefore, the main development direction of "high fiber" feeding in the future of sow feeding: the intake of high fiber diet during pregnancy can significantly improve the number of live births and weaned piglets, and can significantly increase the feed intake during lactation. , to improve the performance of piglets.
