Embodiment 1

[0034] The preparation of embodiment 1 fermented leaf powder

[0035] (1) Preparation of mixed bacterial liquid of Aspergillus niger and Bacillus subtilis:

[0036] Preparation of Aspergillus niger spore suspension:

[0037] Seed medium (PDA) preparation: distilled water 1000mL, potato extract powder 6g, glucose 20g, agar 16g, sterilized at 115°C for 30min;

[0038] Strain preparation: insert the activated mold into the PDA medium with an inoculation loop, and culture at a constant temperature of 30°C for 3-4 days until the spores mature;

[0039] Preparation of the spore suspension: elute the spores with an appropriate amount of sterile water, put them into a shaker flask equipped with glass beads, shake horizontally at 140r / min for 1h, and make a concentration of 1×10 after hemocytometer counting. 6～7 CFU / mL of spore suspension.

[0040] Preparation of Bacillus subtilis bacterial liquid: 3g / L beef extract, 10g / L peptone and 5g / L sodium chloride were dissolved in an approp...

Embodiment 2

[0047] The preparation of embodiment 2 fermented leaf powder

[0048] (1) Preparation of Aspergillus niger and Bacillus subtilis mixed bacterial liquid: with embodiment 1

[0049] (2) Mixed fermentation:

[0050] After mixing the dried and pulverized leaves and 10% glucose water according to the mass concentration (W:W=2:1), add 12% mixed bacterial liquid of Aspergillus niger and Bacillus subtilis respectively, after stirring evenly, in 32°C Under the condition of constant temperature, the Qupan was solid-state fermentation for 6 days.

[0051] (3) Dry crush detection:

[0052] Dry and pulverize after fermentation, and pass through a 40-mesh sieve.

[0053] Before fermentation, the leaf powder was detected: the content of crude protein was 20.13%, the content of crude fiber was 14.32%, and the content of lysine was 1.26%. Fermented leaf powder: crude protein content 24.75%, crude fiber content 9.71%, lysine 2.02%.

Embodiment 3

[0054] The preparation of embodiment 3 fermented leaf powder

[0055] (1) Preparation of Aspergillus niger and Bacillus subtilis mixed bacterial liquid: with embodiment 1

[0056] (2) Mixed fermentation:

[0057] After mixing the dried and pulverized leaves with 10% mass concentration of glucose water (W:W=2:1), add 15% mixed bacterial liquid of Aspergillus niger and Bacillus subtilis respectively, stir evenly, and set the temperature at 35°C Under the condition of constant temperature, the koji plate was fermented in solid state for 5 days.

[0058] (3) Dry crush detection:

[0059] Dry and pulverize after fermentation, and pass through a 40-mesh sieve.

[0060] Before fermentation, the leaf powder was detected: the content of crude protein was 20.13%, the content of crude fiber was 14.32%, and the content of lysine was 1.26%. After testing, in the fermented leaf powder: the content of crude protein is 23.95%, the content of crude fiber is 9.86%, and the content of lysine...

Abstract

The invention discloses a lactating sow feed and belongs to the technical field of animal feed. The lactating sow feed comprises fermented broussonetia papyrifera leaf powder, corns, brown rice, extruded soybeans, beet pulp, flaxseeds, soybean hull, alfalfa meal, cane molasses, calcium hydrophosphate, mountain flour, phytase, salt, lysine, methionine, threonine, choline chloride, mildew preventive, microecologics, a compound premixed feed and antioxidant. The fabrication method includes the steps of preliminary screening, crushing, compounding, feeding, mixing, pelletizing and the like. The coarse fiber content of fermented broussonetia papyrifera leaves is low, the coarse protein content is increased, amino acid is more complete, palatability is greatly improved, and the mixed feed fabricated by matching the fermented broussonetia papyrifera leaves with other raw materials can increase food intake of sows, improve the constipation condition of the sows, improve growth performance of suckling pigs and thus increase pig farm production benefits.

Description

technical field [0001] The invention belongs to the technical field of animal feed, in particular to a feed for sucking sows and a preparation method thereof. Background technique [0002] The sow is the engine of a pig farm. The reproductive performance of the sow determines the production index of a pig farm to a certain extent. Sow constipation will greatly affect the reproductive performance of the sow, which is manifested as: reducing feed intake , Prolonged labor time, increased number of stillbirths, induced MMA (mastitis-metritis-anagalactia syndrome), decreased lactation, decreased number of live weaned piglets, etc. Moreover, the milk production and quality of sows determine the growth rate and physique of suckling pigs. Therefore, solving the constipation of sows and improving the milk production performance of sows are the prerequisites for improving the production performance of sows, and then improving the production indicators of the whole pig farm.
