Example 1
The feed additive for promoting grass carp immunity improvement is prepared from the following components in parts by weight: DDGS5 parts, broad bean protein 5 parts, dandelion 0.15 parts, garlic and ginger powder 0.05 parts, tea mushroom 0.01 parts, barberry 0.01 parts, alpha-amylase 0.01 parts, wild chrysanthemum flower 0.05 parts, water peanut 2 parts and spirulina 1 part.
The raw material products are selected from the raw materials sold in the market, wherein dandelion, agrocybe aegerita, berberis thunbergii, wild chrysanthemum, alternanthera philoxeroides and spirulina are cleaned by deionized water, dried in the shade, ground into 80-100 meshes, uniformly mixed with DDGS, broad bean protein, garlic and ginger powder and alpha-amylase, doped according to 5% of the conventional feed of grass carp feed, and processed into the commercial feed according to the conventional processing mode of the grass carp feed.
The experimental grass carp was domesticated in a water pond for 2 weeks, during which commercial grass carp juvenile feed (crude protein content 32%, crude fat content 4%) was fed. After 24h of hunger treatment, selecting individuals with strong physique and similar physique and weighing, setting 3 times of hunger treatment, randomly distributing the hungry test grass carps into 800L water tanks, and stocking 20 test grass carps with initial body mass of (57.11 +/-0.19) g in each water tank. The feed additive and commercial grass carp juvenile feed adulterants (8:00 and 16:00) in the embodiment are fed for 2 times per day of apparent satiation, and natural illumination is adopted in the period, and air inflation and oxygenation are ceaselessly performed.

Through determination, the survival rate of the experimental fish is 100%, the mass of the terminal body is 141 +/-0.38 g, the activity of the serum lysozyme is 9.38 +/-0.42 unit/mu L, and the content of the serum protein is 55.22 +/-1.08 mg/mL.
Comparative example 1
The pure commercial young grass carp feed (the crude protein content is 32 percent, and the crude fat content is 4 percent) is adopted.
The experimental fish were kept in a water tank for 2 weeks, during which commercial young grass carp feed (crude protein content 32%, crude fat content 4%) was fed. After the domesticated experimental fish is subjected to starvation treatment for 24 hours, individuals with strong physique and similar physique are selected, grouped and weighed, 3 times of treatment are set, the individuals are randomly distributed into 800L water tanks, and 15 tails of the experimental fish with the initial body mass of (57.12 +/-0.19) g are stocked in each water tank. Commercial young grass carp feeds (8:00 and 16:00) sold in the embodiment are fed for 2 times every day after apparent feeding, and natural illumination is adopted during the feeding period, and the feeding is continuously carried out through aeration and oxygenation. The culture experiment lasts for 60 days. At the beginning of the breeding experiment, 5 fish were randomly selected and stored at-80 ℃ for analysis of the body composition of the initial sample. And (4) after the culture experiment is finished, fasting the experimental fish for 24 hours, and counting the fish tails and the total mass of each water tank. Then, 1mL of blood was randomly sampled from the vein of 5 experimental fishes, and the blood was left standing at 4 ℃ for 4 hours and centrifuged (836 Xg, 10min, 4 ℃) to obtain serum for measuring immunological index. Through determination, the survival rate of the experimental fish is 100%, the mass of the final body is 120.87 +/-0.26 g, the activity of the serum lysozyme is 5.53 +/-0.11 unit/mu L, and the content of the serum protein is 42.63 +/-0.21 mg/mL.
Comparative example 2
The difference from example 3 is that no garlic ginger powder and no alpha-amylase are added.
Experiments were conducted in Tongwei feed Limited in Jiangsu salt City. The experimental fish were domesticated in the pond for 2 weeks, during which commercial young grass carp feed (crude protein content 32%, crude fat content 4%) was fed. After the domesticated experimental fish is subjected to starvation treatment for 24 hours, selecting individuals with strong physique and similar physique and weighing, setting 3 times of the starvation treatment, randomly distributing the starvation treatment to 800L water tanks, and stocking 15 tails of the experimental fish with initial body mass of (56.12 +/-0.14) g in each water tank. The feed additive and commercial grass carp juvenile feed adulterants (8:00 and 16:00) in the embodiment are fed for 2 times per day of apparent satiation, and natural illumination is adopted in the period, and air inflation and oxygenation are ceaselessly performed. The culture experiment lasts for 60 days. At the beginning of the culture experiment, 5 fish were randomly picked and stored at-80 ℃ for analysis of the body composition of the initial sample. At the end of the culture experiment, the experimental fish are fasted for 24h, and the fish tails and the total mass of each water tank are counted. Then randomly taking 1mL of blood from 5 experimental fish veins, standing the blood at 4 ℃ for 4h, centrifuging (836 Xg, 10min, 4 ℃), and taking serum for measuring immunological index. Through determination, the survival rate of the experimental fish is 100%, the mass of the final body is 126 +/-0.32 g, the activity of the serum lysozyme is 5.78 +/-0.24 unit/mu L, and the content of the serum protein is 43.38 +/-0.68 mg/mL.
In conclusion, the feed additive for promoting the immunity of the grass carps to be improved and the application thereof are characterized in that DDGS, broad bean protein, dandelion, garlic ginger powder, agrocybe aegerita, berberis thunbergii, alpha-amylase, wild chrysanthemum flower, alternanthera philoxeroides and spirulina are adopted, the synergistic effect of the garlic ginger powder and the alpha-amylase is utilized, and the DDGS, broad bean protein, dandelion, agrocybe aegerita, barberry, wild chrysanthemum flower, alternanthera philoxeroides and spirulina are combined, so that the immunity of the freshwater fish can be enhanced, and the survival rate of the grass carps is ensured without adding hormones.
