Embodiment Construction
[0014] The technical solution will be described in detail through specific experiments below.
[0015] Before the experiment, they were temporarily raised in a recirculating aquaculture system for 10 days, and fed with basic feed. Before the formal experiment, all experimental fish were stopped for 24 hours and anesthetized and weighed (MS-222, 40 mg / L). 396 Atlantic salmon juveniles were randomly selected, healthy and lively, with the same size, and an average weight of (142.65 ± 17.64) g. In 12 experimental recirculating aquaculture systems, 4 treatment groups were designed in the experiment, each treatment had 3 replicates, and each replicate had 33 fish. The control group was fed with basal feed, and the treatment group was fed with 100 mg / kg, 200 mg / kg, and 400 mg / kg experimental feed of antioxidant compound preparation, respectively, for 83 days.
[0016] The composition and nutrient composition of the experimental basal feed are shown in Table 1. The test feed is a sp...

The present invention belongs to the technical field of preparations of antioxidants and discloses an antioxidant for maricultured young salmo salar and a preparation technology thereof. The antioxidant comprises 8% of glutathione, 20% of vitamin C, 10% of vitamin E and 62% of saccharomyces cerevisiae cell walls, wherein the saccharomyces cerevisiae cell walls comprise 43% of crude proteins, 17% of mannooligosaccharides and 20% of beta-glucan. A technical scheme uses a natural antioxidant compound preparation. The antioxidant solves problems of oxidative damages and liver damages in an industrial culture of the salmo salar via a nutrition regulation, reduces the oxidative damages and liver damages of the salmo salar, is greener, promotes an improvement of growth performances, improves antioxidant capacities and immune levels, significantly improves tolerance and survival rates of the industrially cultured salmo salar in high-density culture, ammonia nitrogen concentration increase, hypoxia and other unfavorable environment, and is advanced in technology, strong in maneuverability, true and reliable in effects and convenient in operations.
Description
technical field [0001] The invention belongs to the technical field of antioxidant preparation, and in particular relates to an antioxidant, a preparation process and a feed for Atlantic salmon juveniles cultured in seawater. Background technique [0002] Atlantic salmon belongs to the family Salmonidae and is a cold-water fish. According to its different living habits, it can be divided into two types: migratory type and land-sealing type. Atlantic salmon muscle is rich in omega-3 long-chain highly unsaturated fatty acids, which has high food nutritional value and economic benefits. However, due to the high density and high feeding frequency of industrialized Atlantic salmon, the probability of fish infection is very high. At the same time, the feed of Atlantic salmon is high-fat and high-energy feed, and the intake of high-energy feed increases the digestive organs such as the liver. The burden and pressure of the fish can easily cause oxidative damage to the liver and ot...
