Embodiment Construction

[0007] Vitamin A, 12kg; vitamin C-2-phosphate, 25kg; potassium dichromate, 12kg; vitamin E, 20kg; vitamin B2, 6kg; magnesium sulfate, 10kg; selenium methionine, 5kg; zinc methionine, 10kg. These raw materials are pre-crushed and passed through a 120-mesh sieve, and then mixed evenly to obtain the oval pomfret anti-stress feed additive.

[0008] According to the addition amount of 0.1-0.2%, the anti-stress feed additive for pomfret ovata and the feed raw material for pomfret ovata are evenly mixed and pelletized.

[0009] The breeding experiments in Ningde, Fujian, Zhanjiang, Guangdong and other places in 2005-2006 showed that after the popularization and use of this anti-stress agent, it can effectively prevent the stress of pomfret ovata during the whole cycle breeding process and effectively alleviate the stress of pomfret. The cold weather in the first half of the year and the typhoon and rainstorm in the second half of the year brought losses to the breeding industry. The...

Abstract

The invention relates to an anti-stress feed additive for golden pomfrets, which comprises following ingredients by weight percentages: 10 to 15 percent of vitamin A, 20 to 30 percent of vitamin C-2-phosphate, 10 to 15 percent of potassium dichromate, 10 to 20 percent of vitamin E, 5 to 10 percent of vitamin B2, 5 to 10 percent of bitter salt, 5 to 10 percent of selenium methionine and 5 to 10 percent of methionine. The invention has the advantages that stress of the golden pomfrets can be notably released, the ingestion rate of the golden pomfrets is improved, and the growth of the golden pomfrets is stimulated; the live rate of the golden pomfrets in a complete culture period and the unit yield are improved, and the economic benefits of golden pomfret culture are increased; the meat quality of the golden pomfrets is improved, the product quality is improved, and foreign currency by exporting the golden pomfrets is increased; and raw materials for the anti-stress feed additive have stable resources, low cost and simple production technology.

Description

technical field [0001] The invention relates to a seawater fish feed additive, in particular to an anti-stress feed additive for oval pomfret. technical background [0002] The so-called stress refers to a non-specific response of aquatic animals to adverse environmental factors. These factors include: sudden changes in water temperature (such as the impact of cold currents and intense heat), sudden changes in water quality (such as the impact of typhoons, heavy rains, etc.), excessive stocking density, malnutrition, and other external stimuli. [0003] Oval pomfret (Trachinotus ovatus), commonly known as golden pomfret, is a rare edible fish with tender meat and delicious taste. It is a marine cultured fish with important economic value in southern my country. Due to the high stocking density, the pollution of the sea area, and the complex and changeable environment of the sea area, the pomfret is often in a state of stress during the breeding process, which seriously affe...
