Embodiment Construction

[0007] Aiming at the special metabolic characteristics of grouper, the present invention creatively develops a "high-efficiency liver-enhancing agent for grouper", forming a new technology to support the sustainable and efficient development of grouper feed industry and breeding industry.

[0008] Weigh 30kg of vitamin C-polyphosphate, 20kg of vitamin E, 15kg of choline; 10kg of L-carnitine, 10kg of lecithin, 5kg of selenium methionine, 5kg of EPA, and 5kg of DHA. These raw materials are fully mixed evenly, which is the grouper liver strengthening agent.

[0009] From 2005 to 2006, experiments in Guangdong and Hainan showed that the grouper feed coefficient decreased by 14.6% and 16.3% and the survival rate increased respectively compared with the control group when the liver-enhancing agent was used in the whole cycle of grouper inshore cage culture. 18.9% and 23.3% (Table 1).

[0010] Table 1 Adding liver-enhancing agent to compound feed, experimental results of offshore ca...

Abstract

The invention relates to a rudd hepatinica which comprises the following ingredients by weight percentages: 20 to 30 percent of vitamin C-phosphate, 15 to 20 percent of vitamin E, 10 to 20 percent of choline, 5 to 10 percent of l-carnitine, 5 to 10 percent of lecithin, 5 to 10 percent of selenium methionine, 5 to 10 of eicosapentaenoic acid and 5 to 10 of docosahexaenoic acid. The invention has the advantages that the the rudd hepatinica functioning as the feed additive in rudd feed is added only by 0.1 percent to 0.2 percent; the fatty infiltration of rudd liver can be prevented, the liver function of the rudd is enhanced, the feed efficiency is improved, the growth of the rudd is promoted, and the live rate of the rudd is improved. The invention has no influence on the palatability of the rudd feed, and raw materials adopted in the hepatinica have stable resources, low cost and simple production technology.

Description

technical field [0001] The invention relates to a feed additive, in particular to a grouper liver strengthening agent. technical background [0002] Fatty liver problem is a fairly common problem in the artificial culture of marine fish. Diseased fish show loss of appetite, slow growth, low feed remuneration, and severe death. Although there are sporadic reports on the basic research on the pathogenesis of fatty liver at home and abroad, the research is not systematic. Although there are also some additives or drugs for preventing and treating fatty liver in the domestic market, the effect is not good, and the outstanding performance is that the effect is unstable, and the improvement of disease resistance and survival rate is not obvious. [0003] Grouper is a warm-water offshore bottom rare fish. The meat is plump, tender, and nutritious, and is highly praised by people. Live fish is sold in Hong Kong and Macao markets, and is regarded as a first-class delicacy, and the...
