specific Embodiment 1

[0018] 1 Select 50 kg of fresh queen bee fetuses, and the queen bee fetuses are required to be intact, white and tender, without damaged black spots. Put it in the container, add 100 kg of pre-cooled (4°C) cleaning and fresh-keeping aqueous solution, and the cleaning solution is composed as follows according to the mass percentage of each component: 2% ascorbic acid, 20% absolute ethanol, and 78% deionized water. Place the container on a shaker for oscillating rinsing, the frequency of oscillating cleaning is 50 rpm; the duration of oscillating cleaning is 20 minutes; after the end, drain the aqueous solution, leave the queen bee, add 100 kg of fresh-keeping aqueous solution again, and carry out the second cycle according to the above conditions. Shake rinse. A total of 2 shock cleaning times. Finally drain the water solution, leaving the queen bee.

[0019] 2 Add 5 kg of pre-cooled (4°C) aqueous solution containing stabilizer to the above queen bee embryo, and mix well. Th...

[0025] Specific Example 2: This example provides the application of the queen fetoprotein announced by the present invention in the feeding of nursery pigs

[0026] 1. Materials and methods

[0027] 1.1 Test material

[0028] Fetal protein powder for feeding

[0029] 1.2 Experimental animals and experimental design

[0030] This experiment adopts a single factor experimental design, selects 80 healthy Du × long × large nursery pigs with a weight of about 10KG, and divides them into 4 groups according to the principle of similar parity and half male and female, with 2 repetitions in each group. The control group was the basal diet, and the other three experimental groups added 100 mg / kg, 200 mg / kg, and 400 mg / kg of queen bee fetal protein powder to the basal diet respectively.

Abstract

The invention relates to a queen fetoprotein used for a feed and a preparation technology thereof. The royal jelly byproduct-bee larva is taken as a main raw material, high protein content is fully used, amino acid composition is reasonable, and the biological activity component is abundant, and the material is developed to the novel protein used for the feed. A key point of the preparation technology comprises the steps of fresh-keeping and cleaning of bee larva, addition of a stabilizing agent, refrigeration and crushing of the raw materials, and vacuum low-temperature microwave drying. On one hand, the queen fetoprotein and its active substance can be maximally preserved; on the other hand, the automation degree is high, cost is low, and the technology is suitable for large-scale industrial production, and the product takes the queen fetoprotein as the novel protein powder used for the feed, which can be used for the feed and a breeding industry.

Description

technical field [0001] The invention relates to a novel feed protein mainly composed of queen bee fetal protein and a preparation process thereof, belonging to the field of feed protein processing. Background technique [0002] The queen bee fetus is the larvae formed by the fertilized eggs of bees fed by worker bees with fresh royal jelly, that is, the queen bee larvae collected from the royal platform. The study found that the water content in the queen bee fetus accounts for about 80% of the total mass, crude fat and crude protein account for 18% and 56% of its dry weight respectively, the total content of 18 kinds of amino acids is 46g / 100 g dry weight, and the content of essential amino acids accounts for 46% of the dry weight. The ratio of essential amino acid to non-essential amino acid content (NEAA) is 0.98. It is also rich in vitamins and minerals. Therefore, the queen bee fetus can be used as a feed protein resource with high nutritional value, and has high deve...
