Embodiment 1

[0012] Add 0.3 times the weight of rice bran to 25% medical glucose solution and 0.8 times the compound amino acid injection 18aa to the rice bran, adjust the pH to 5.5, inoculate Geotrichum candidum, cultivate and ferment for 42 hours at 23°C, press and separate to obtain the fermentation broth;

[0013] The mustard seeds were kept under a steam pressure of 2.5MPa for 10 minutes, and 3 times the volume of distilled water was added for 3 hours at 95°C in a water bath to obtain the extract. Add the fermentation broth of 1 times the weight of the extract, After 20 hours of fermentation at ℃, the secondary fermentation broth was obtained, which was spray-dried under the drying conditions of feed temperature of 22℃, inlet temperature of 80℃, and atomizer pressure of 80kPa.

[0014] The obtained feed additive for laying ducks in summer has a clear fragrance of celery, a sweet and slightly spicy taste, and the content of B vitamins is 0.02654 mg / g.

Embodiment 2

[0016] Add a 25% medical glucose solution with a concentration of 0.4 times the weight of the rice bran to the rice bran, and a 0.9 times the compound amino acid injection 18aa, adjust the pH to 6, inoculate Geotrichum candidum, cultivate and ferment for 43 hours at 24°C, press and separate to obtain the fermentation broth;

[0017] The mustard seeds were treated with a steam pressure of 2.65MPa for 11 minutes, and 3.5 times the volume of distilled water was added for 4 hours at 96°C in a water bath to obtain an extract. Add 1.2 times the weight of the extract to the fermentation broth. After 21 hours of fermentation at ℃, the secondary fermentation broth was obtained, and the feed temperature was 22℃, the inlet temperature was 80℃, and the atomizer pressure was 85kPa. The feed additive for laying ducks in summer was obtained by spray drying.

Abstract

The invention relates to the technical field of poultry feed, in particular to a feed additive for a laying duck in summer. The feed additive is prepared by taking semen sinapis and rice bran as raw materials; when the feed additive is manufactured, a medical glucose solution and a compound amino acid injection 18aa are added into the rice bran; inoculating geotrichum candidum for fermenting, and then squeezing and separating to obtain a fermentation liquor; mixing the fermentation liquor and a semen sinapis leaching liquor, continuously fermenting, and spray-drying to obtain the feed additive for the laying duck in summer. The obtained feed additive for the laying duck in summer has the faint scent of celery, is sweet in taste, is slightly spicy, is high in active enzyme content, and has the effects of improving the immunity of the laying duck and reducing the heat stress response of the laying duck.

Description

Technical field [0001] The invention relates to the technical field of poultry feed, in particular to a feed additive for laying ducks in summer. Background technique [0002] Laying ducks are cold-tolerant and afraid of heat. Due to the hot summer climate, and since spring, ducks have been laying eggs and are undernourished. They are prone to hair loss and will stop laying eggs if they are not properly managed. In addition, the high temperature climate will cause severe heat stress to the laying ducks. If not managed properly at this time, not only will the laying rate decrease, but also the death of the ducks may be caused. Summary of the invention [0003] The purpose of the present invention is to provide a feed additive for laying ducks in summer. [0004] The technical scheme adopted by the present invention is: a feed additive for laying ducks in summer, the feed additive is made of mustard seeds and rice bran as raw materials, [0005] When making, add 0.3-0.5 times the we...
