Shrimp feed should be added cholesterol
Shrimp feed should be added cholesterol
Japan's fisheries experts recently pointed out that the shrimp in the whole period of the young normal growth require sterols, and cholesterol is the only
Biological activity of shrimp and crab in various sterols.. Therefore, in order to ensure the normal growth of juvenile shrimp should be in shrimp fed diets supplemented with cholesterol. The experimental results show that
The appropriate dose of cholesterol required for juvenile shrimp is about 0.5% of the feed.
Experts believe that the use of pure cholesterol as a direct additive for shrimp feed, which is the best way to ensure the rational effect of cholesterol meta bolism and the effect of cholesterol.
