Abstract

The invention discloses feed additive which improves the quality of large yellow croaker. The feed additive consists of two or three types in conjugated linoleic acid, vitamin E and soybean flavone by proportion. 1 percent to 5 percent of large yellow croaker quality modifying addition is added into large yellow croaker feed to feed the large yellow croaker, which can obviously reduce the content of malonaldehyde in large yellow croaker muscle, prevent fat oxidation, reduce the body fat content of the large yellow croaker, improve the figure of the large yellow croaker, improve the unsaturated fatty acid content in the large yellow croaker muscle, reduce the saturated fatty acid content in musculature, improve the skin color of the large yellow croaker, so that the large yellow croaker has tender fish and good taste. The feed additive which improves the quality of the large yellow croaker of the invention can obviously improve the quality of the cultivated large yellow croaker, and is safe without public harm and residue; and the cultivated large yellow croaker meets the green food sanitation requirements.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for improving the quality of large yellow croaker. Background technique [0002] Large yellow croaker is one of my country's traditional "four seafood" (large yellow croaker, small yellow croaker, hairtail, squid). Its meat is delicious and nutritious, and it can be processed into special aquatic products in addition to being eaten fresh. At the same time, the fish also has high medicinal value. Its otoliths have the functions of clearing away heat and blood stasis, dredging stranguria and diuresis; Due to predatory fishing and environmental pollution, wild large yellow croakers are hard to find. With the success of large yellow croaker artificial fry technology, cage culture of large yellow croakers has developed rapidly. At present, more than 95% of large yellow croakers sold in the market are farmed. Large yellow croaker farming mainly adopts seawater cage technology. The a...
