Embodiment 1
[0013] Weighed 60 g of cytosine nucleotide, 8 g of uracil nucleotide, 10 g of thymine nucleotide, 2 g of hypoxanthine nucleotide (IMP) and 20 g of bioactive peptides purchased from Beijing Sangpu Biotechnology Co., Ltd., the mixture was ground and pulverized, and then sieved with a sieve, wherein the fineness of the sieve was required to be 80-120 mesh. The filtered powder is dried until the weight of the powder is reduced by 10% compared with that before drying; thus the required immune enhancer is prepared.
Embodiment 2
[0015] Weighed 55g of cytosine nucleotides, 10g of uracil nucleotides, 15g of thymine nucleotides, 5g of inosine nucleotides and 5g of inosine nucleotides purchased from Shandong Shuangfeng Co., Ltd. Bioactive Peptides of Technology Ltd. 15g. The fineness requirement is 80-120 mesh, and the loss on drying is ≤10.0%. Get the needed immune booster.
Embodiment 3
[0017] Weighed 65 g of cytosine nucleotides, 5 g of uracil nucleotides, 15 g of thymine nucleotides, 3 g of inosine nucleotides and 3 g of inosine nucleotides purchased from Shandong Shuangfeng Co., Ltd. Bioactive Peptides of Technology Ltd. 12g. The fineness requirement is 80-120 mesh, and the loss on drying is ≤10.0%. Get the needed immune booster.
[0018] The use method and dosage of the above-mentioned immune enhancer are as follows: add 0.2-0.5 g of the immune enhancer to each kilogram of flounder feed, and make pellet feed for feeding.
[0019] The present invention will be further described below in conjunction with the non-specific immune index and disease resistance obtained from the compound nucleotide immune enhancer feeding test.
