Embodiment 1

[0039] The nutritional components of konjac flying powder collected from two manufacturers in Shaanxi and Yunnan were analyzed, as shown in Table 1.

[0040] Table 1 Nutritional composition of konjac powder (air-dried basis)

[0041]

[0042]

Embodiment 2

[0043] The water absorption of embodiment 2 konjac flying powder

[0044] Weigh m1 2g of the sample to be tested into a 50mL centrifuge tube, add 20mL of water with a pipette, shake the centrifuge tube vigorously back and forth by hand, and place it on a shaker for 30 minutes to fully disperse the sample and absorb water; then centrifuge at 3000r / min for 5min, Pour out the supernatant in the centrifuge tube, weigh the weight m2 of the precipitate, and calculate the water absorption of the sample according to the following formula. Repeat for each sample.

[0047]

[0048] Weigh 5g, 2.5g, and 1.67g of konjac flying powder from a company in Yunnan into 50ml of water, stir well, and make konjac flying powder aqueous solutions with ratios of 1:10, 1:20, and 1:30.

[0049] The ratio of konjac flying powder to water is 1:10, which is relatively viscous, and 1:20 and 1:30 are less viscous...

Embodiment 3

[0051] 1 Experimental animals and design

[0052] The experiment was carried out in Taicang breeding pig farm of Anyou Group, Jiangsu. A total of 36 sows with 3-6 parities in good body condition, expected date of farrowing and similar parity were selected and randomly divided into 3 groups with 12 replicates in each group and 1 sow in each replicate. The control group was fed according to Table 3, and the two test groups were added with 2% and 4% konjac fly powder respectively. The experiment was divided into two stages: the first stage was from 30 days before delivery to the day of farrowing; the second stage was from the day of farrowing to weaning of piglets on 30 days. Konjac flying powder was provided by a company in Shaanxi. The nutrient composition of the diet is shown in Table 3.

Abstract

The invention discloses an application of konjac flying powder in sow feed and the sow feed, based on the mass percentage content, the application comprises the following steps of adding 1%-6% of thekonjac flying powder in conventional sow feed, controlling the content of insoluble fibers in daily feed for sows to be 10%-20%, controlling the content of soluble fibers to be 2%-5%, and controllingthe ratio of the insoluble fibers to the soluble fibers to be 3: 1 to 6: 1; and the invention further discloses the sow feed containing 1%-6% of the konjac flying powder, the konjac flying powder is applied to reduce the feed cost, so that the feed intake and immune function of the sows are improved, the weaning litter weight and daily gain of piglets are increased, the pH of excrement is reduced,digestion is promoted, constipation of the sows is improved, mycotoxin is adsorbed, and the granulation quality of the feed is improved. As a cheap functional raw material, the konjac flying powder has obvious effects in improving intestinal health of the sows and improving production performance of the sows and the piglets, and has important significance in improving live pig breeding benefits.

Description

technical field [0001] The invention belongs to the field of sow breeding, and in particular relates to a feed eaten during sow breeding, in particular to the application of konjac flying powder in sow feed and the sow feed. Background technique [0002] Constipation is the main problem in the breeding process of sows, especially in summer, which can easily lead to dystocia and postpartum agalactia in sows, which seriously affects the breeding performance. At present, the solutions to constipation in sows include increasing drinking water, increasing the amount of fiber, applying probiotic products, applying drugs such as magnesium sulfate, and increasing the amount of oil. The application of fiber raw materials is a commonly used method in feed. Such as bran, rice bran, beet meal, apple pomace, soybean skin, grass powder, etc. These raw materials are prone to mold and deterioration, and mycotoxins can easily exceed the standard. Beet meal belongs to soluble fiber, but th...
