Embodiment Construction

[0037] 1. Making fermented okara:

[0038] 1). Okara: 50kg

[0039] 2).Based on bean dregs, add 2.5-5kg soybean meal, 1-4kg sweet potato starch, 2.5-5kg wheat bran, 0.1-0.2kg salt, 0.025kg yeast, 0.018-0.02kg Vitality 99 starter, 0.018 -0.02kg roughage degradation agent, 0.2-0.3kg calcium hydrogen phosphate.

[0040] 3). Put the raw materials into a mixer, add 10-20kg of water and stir for 5-10 minutes to synthesize a premix with a water content of 40-60%.

[0041] 4). Put the premixed material into the underground fermentation tank, cover and seal it with a film, use geothermal heat to keep the temperature range of 15-35°C, and carry out fermentation under anaerobic conditions. Under the action of probiotics (such as yeast, lactic acid bacteria, bacillus, etc.), under the action of β-glucanase, cellulase, xylanase, etc., the feed will completely react within 5-10 days.

[0042] 5).Deflate once every two days.

[0043] 6). Fermentation for 5-10 days.

[0044] 7). After 5-...

Abstract

The invention provides forage improving ovulation amount of back-up nonpregnant sows and a manufacturing method thereof. A recipe includes 42 kg of fermented bean dregs, 0.40-0.45 kg of soybean oil, 30-40 kg of corn, 15-18 kg of wheat bran, 8-10 kg of fermented soybean meal, 3-6 kg of premix, 2-4 kg of oil powder, 0.125 kg of baking soda, 0.040 kg of multivitamin, and 0.05 kg of lysine. The materials are sufficiently mixed by stirring to get the finished product. The back-up nonpregnant sows are raised by the forage. The primiparity sows ovulate 19.35 on average, and the multiparity sows ovulate 24.69 on average. Fecundity is significantly improved.

Description

technical field [0001] The invention relates to a feed formula, specifically a kind of fermented bean dregs as the main raw material, in which other auxiliary materials are added. Feed formulation to increase ovulation in gilts and empty sows. Background technique [0002] Okara contains a lot of ingredients that are useful to pigs, but it also contains anti-nutritional factors, and the fermentation of okara can effectively decompose harmful ingredients. [0003] In the traditional feeding of gilts and empty pregnant sows, in order to increase the amount of ovulation, 20mg of ovulation stimulation No. 3 is often injected intramuscularly after the first mating of sows, which can promote ovulation, increase conception rate and litter size. However, in this method of operation, it is difficult to grasp the exact date of injection, and long-term application of large doses will produce heterogeneous effects, that is, obvious inhibitory effects. [0004] The present invention ut...
