Embodiment 1
[0053] Before mixing, all raw materials are ultrafinely pulverized and passed through an 80-mesh sieve, containing 20 parts by weight of alfalfa saponin, 10 parts by weight of methionine chelated zinc, 5 parts by weight of taurine, 20 parts by weight of feed additives per 100 parts by weight of the feed additive. Pueraria root powder in parts by weight, grape seed proanthocyanidins in 5 parts by weight, and the balance in the proportion of defatted rice bran are mixed to obtain a feed additive for alleviating endoplasmic reticulum stress of sea bass.
[0054] Among them, the ligand ratio of methionine chelated zinc is 3.5:1, and the chelation rate of zinc in methionine chelated zinc is 89%.
Embodiment 2
[0056] The difference between this embodiment and Example 1 is: before mixing, all the raw materials are ultrafinely pulverized and passed through a 100-mesh sieve, and the feed additive contains 30 parts by weight of alfalfa saponin and 20 parts by weight of methionine chelate Zinc, 15 parts by weight of taurine, 30 parts by weight of kudzu root powder and 10 parts by weight of grape seed proanthocyanidins, and the balance is the ratio of defatted rice bran to mix the raw materials to obtain a feed additive for alleviating the stress of sea bass endoplasmic reticulum .
Embodiment 3
[0058] The difference between this embodiment and Example 1 is: before mixing, all the raw materials are ultrafinely pulverized and passed through a 90-mesh sieve, and the feed additive contains 23 parts by weight of alfalfa saponin and 12 parts by weight of methionine chelate Zinc, 8 parts by weight of taurine, 22 parts by weight of kudzu root powder and 6 parts by weight of grape seed proanthocyanidins, and the balance is the proportion of defatted rice bran. The raw materials are mixed to obtain a feed additive for alleviating the stress of sea bass endoplasmic reticulum .
