Embodiment 1

[0017] Add 0.5 times the rice bran weight of 50% medical glucose solution and 0.2 times the compound amino acid injection 18aa to the rice bran, adjust the pH to 5.5, inoculate Geotrichum candidum, culture and ferment at 23°C for 42 hours, squeeze and separate to obtain the fermentation liquid;

[0018] Take fresh Hyacinth fruit, wash it and add fermentation broth 1 times its weight to make a slurry, continue fermentation at 23°C for 13 hours, dry it in a drying chamber with a feed temperature of 22°C, an air inlet temperature of 80°C, and an atomizer pressure of 80kPa. Spray dry under conditions.

[0019] The obtained feed additive for laying hens in summer has an apple flavor and a slightly sweet taste, and the number of live bacteria of Geotrichum candidum is 10 6 More than one per g, the protease activity is 983U / g, the lipase activity is 358U / g, the amylase activity is 1200U / g, and the B vitamin content is 0.0351mg / g.

Embodiment 2

[0021] Add 0.8 times the rice bran weight of 50% medical glucose solution and 0.25 times the compound amino acid injection 18aa to the rice bran, adjust the pH to 6, inoculate Geotrichum candidum, culture and ferment at 24°C for 43 hours, squeeze and separate to obtain the fermentation liquid;

[0022] Take fresh Hyacinth fruit, after cleaning, add 1.2 times its weight of fermented liquid for beating, and continue to ferment at 24°C for 14 hours, then dry it in a drying chamber with a feed temperature of 22°C, an air inlet temperature of 80°C, and an atomizer pressure of 85kPa. Spray drying under the condition to obtain the summer feed additive for laying hens of the present invention.

[0023] The obtained feed additive for laying hens in summer has an apple flavor and a slightly sweet taste, and the number of live bacteria of Geotrichum candidum is 10 6 The protease activity is 992U / g, the lipase activity is 354U / g, the amylase activity is 1258U / g, and the B vitamin content ...

Embodiment 3

[0025] Add 50% medical glucose solution with a concentration of 1 times the weight of rice bran to the rice bran, 0.3 times the compound amino acid injection 18aa, adjust the pH to 6.2, inoculate Geotrichum candidum, culture and ferment at 25°C for 45 hours, squeeze and separate to obtain the fermentation liquid;

[0026] Take fresh Hyacinth fruit, wash and add 1.5 times its weight of fermented liquid for beating, and continue to ferment at 25°C for 15 hours, then dry it in a drying chamber with a feed temperature of 22°C, an air inlet temperature of 80°C, and an atomizer pressure of 90kPa. Spray drying under the condition to obtain the summer feed additive for laying hens of the present invention.

[0027] The obtained feed additive for laying hens in summer has an apple flavor and a slightly sweet taste, and the number of live bacteria of Geotrichum candidum is 10 6 The protease activity is 992U / g, the lipase activity is 368U / g, the amylase activity is 1296 U / g, and the B vi...

Abstract

The invention relates to the technical field of poultry feed, in particular to a summer feed additive for laying hens. The feed additive is prepared from pyracantha fortuneana fruit and rice bran; during production, medical glucose solution and compound amino acid injection 18aa are added into rice bran, after inoculation of geotrichum candidum for fermentation is carried out, pressing and separation are performed to obtain fermentation broth, fermentation broth is mixed with fresh pyracantha fortuneana fruit prior to pulping, and further fermentation is carried out prior to spray-drying to obtain the summer feed additive for laying hens. The summer feed additive for laying hens has apple fragrance, is sweetish in taste and high in active enzyme content, and has the efficacy of clearing heat, reducing summer-heat, promoting appetite, improving immunity of laying hens and lowering heat stress response of laying hens.

Description

technical field [0001] The invention relates to the technical field of poultry feed, in particular to a summer feed additive for laying hens. Background technique [0002] In summer, the temperature is high, the skin of the chicken has no sweat glands, and the body is covered by feathers. Therefore, the chicken is not resistant to high humidity and cannot tolerate continuous high temperature above 30°C. When the house temperature is above 28°C, the chicken starts to open its mouth to breathe, and the hen loses appetite. , Often lead to insufficient intake of nutrients such as protein, energy, vitamins, amino acids and minerals, resulting in decreased egg production, decreased egg weight, and even heat stroke or death. [0003] At present, in order to increase the egg production rate of laying hens in summer, it is generally necessary to improve the environment of the chicken house and add feeding drugs or Chinese herbal medicines to the daily feed; [0004] At present, th...
